How Do Skylights Save Energy

How Do Skylights Save Energy and Reduce Electricity Bills?

Author skylights Categories Al-Mamary Blogs

Skylights are known for being energy-efficient roofing solutions that reduce power consumption and energy bills, making them an ideal choice for spaces that require constant lighting as well as cooling or heating around the clock, depending on the climate. 

Skylight energy efficiency proves most useful in places like shopping malls, airports, hospitals, warehouses, and factories, among other public, commercial, or industrial spaces where lighting and temperature control account for a large proportion of energy consumption. 

So, how do skylights reduce electricity bills? How do they save energy? Continue reading this guide to learn about the features and properties that help skylights lower energy use and discover more valuable information about their thermally efficient performance. 

What Makes a Skylight Energy Efficient? Features & Properties

A lot of work goes into making skylights energy efficient, from the initial planning of their shape and orientation to the manufacturing process. In other words, skylights do not simply happen to be energy efficient. Their design incorporates various features and considerations that help optimise energy use and improve overall performance.

So, why are skylights energy-efficient? Here are some of the technical features and properties of energy-efficient skylights:

1. Low-E Glazing

If you are looking into various skylight materials or exploring skylight installation, you may have already come across the term “Low-E glazing,” which stands for Low-Emissivity Glazing. 

In this context, glazing is the transparent material used in skylights that lets natural light into your interior space. When this material, typically glass, is described as low-emissivity, it means that its surface emits less radiant heat, helping provide better temperature control. 

To make the glazing low-emissivity, it is designed with a very thin, almost invisible coating that helps reflect indoor heat back into the building during winter, instead of allowing it to escape. Low-E skylights also help reduce the amount of solar heat entering from outside during summer. 

This way, your indoor place remains cool in the summer and warm in winter, significantly reducing reliance on HVAC systems for heating and cooling. This first feature is very important in designing energy-efficient skylights. 

2. U-Value 

“U-Value” stands for “thermal transmittance” and it measures how much heat passes through the skylight. Unlike low-E glazing, U-value is not a singular feature but rather an overall measure of the skylight’s thermal performance, taking into account various factors, such as: 

  • Glass/glazing: The material type, its thickness, and the application of the low-e coatings all impact the skylight’s U-value. 
  • Number of panes: Glazing provides better insulation when the panes are doubled or tripled, especially when there is insulating gas between them. 
  • Frame: The material and design of the skylight frame also affect heat transfer.
  • Installation: Poor installation can negatively impact thermal performance.

That being said, a skylight with a low U-Value provides better insulation and greater energy efficiency, while a skylight with a high U-value does the opposite. But how does U-value make skylight energy efficiency possible?

With the proper glazing, coatings, installation, and more, the U-value is reduced, meaning that the skylight limits heat transfer through its panes. The end result? Less heat loss in winter and heat gain in summer, minimising the workload on heating and cooling systems and improving energy efficiency.

3. SHGC 

SHGC (Solar Heat Gain Coefficient) measures how much solar heat enters a building through the skylight. A lower SHGC limits solar heat gain, making it useful in hot climates like the UAE, while a higher SHGC allows more solar heat to enter, which is beneficial in colder climates by helping warm the space. In both cases, the proper SHGC rate is crucial to skylight energy efficiency. 

It is important to distinguish between U-value and SHGC; the first measures heat transfer through the skylight, while the latter measures solar heat entering through it. Notably, SHGC is impacted by a variety of aspects, including but not limited to: 

  • Type of Glazing: Different skylight materials absorb, reflect, and transmit varying amounts of solar radiation. 
  • Low-E Coatings: Some low-emissivity coatings can minimise the amount of solar heat passing through the skylight. 
  • Tinting: Tinted glass can transmit less solar radiation through the skylight, depending on its shade and formula. 
  • Design & Orientation: The skylight design, configuration, and orientation have a direct impact on the amount of solar heat that can enter through it, significantly affecting the SHGC measurement.  

So, how does the SHGC rate contribute to skylight energy savings? The proper SHGC rate minimises the need for cooling and heating systems to work continuously to control indoor temperature and keep it at a comfortable level. Therefore, energy-efficient skylights reduce energy bills through a combination of features that achieve the suitable SHGC levels. 

4. Double & Triple Glazing 

Skylight glazing can comprise a single pane, or it can be double glazed or triple glazed. Meaning? A double-glazed skylight has two layers or panes of glass with a sealed space between them, which can be filled with an insulating gas for better insulation. A triple-glazed skylight has three panes of glass and two sealed spaces between them. 

How do skylights save energy, then? Double and triple panes are one of the most effective ways to improve the skylight’s thermal performance and energy-saving capacity. What these additional panes do is create greater resistance to heat transfer, keeping your place cool in summer and warm in winter by reducing heat gain and loss. 

As a result, such double- and triple-glazed energy-efficient skylights lower HVAC demands and help reduce energy bills. 

5. Visible Transmittance (VT)

This aspect is part of the reason why skylights are energy-efficient. Visible transmittance means the percentage of visible light that passes through the skylight’s glazing to illuminate the indoors, and it is determined by laboratory testing of the glazing. The higher the transmittance, the more visible light passes through, so brighter the space is. 

But how does a high VT help skylights reduce electricity bills? 

Skylights with good visible transmittance bring more natural daylight indoors, meaning that you do not need to rely on artificial lighting as much during the day. This is significant in big places that need constant lighting and a pleasant environment, including hospitals, schools, public buildings, shopping centres, and others. 

Now that you know how and why skylights are energy-efficient, it is important to understand how they reduce energy consumption. So, how do skylights save energy? 

How Do Skylights Save Energy? 

How do skylights reduce energy costs? How do the above energy-saving properties and features translate into lowered electricity bills and reduced energy consumption? Now that you know what makes an energy-efficient skylight, here is exactly how it saves you energy: 

1) Natural Daylight 

A skylight’s most prominent function is providing natural lighting. No matter the type of skylight, its shape, or material—it is designed to allow natural daylight to fill in the place. And since skylights are positioned overhead, they distribute light deeply into interiors, illuminating the area more efficiently compared to vertical windows. 

As such, skylights with a high visible transmittance play a major role in reducing reliance on artificial lighting. There is no need to switch to electrical lighting when the entire place basks in sunlight with no hues or harsh glare. As a result, skylights reduce electricity bills and minimise operational costs. 

2) Reduced Cooling Energy

Skylights can be designed to allow an abundance of natural light to come inside while minimising solar heat gain, which is a major advantage in hot climates like the UAE and other GCC countries. Such skylights integrate proper glazing, suitable SHGC rates, and insulation mechanisms like double- or triple glazing and insulating gas. 

With the right features and mechanisms, skylights do not let much heat pass through them. Consequently, HVAC systems do not need to work excessively to keep the place cool, reducing energy consumption and bill amounts. 

3) Passive Solar Heating

Skylight energy efficiency is not limited to daylight and cooling performance only, as it plays an important role in heating as well. Skylights installed in colder locations can let sunlight inside, which provides useful heat to the interior. With the proper insulation and SHGC, these skylights help maintain a warm and comfortable temperature through passive solar heating. 

How does this contribute to skylight energy savings? 

Instead of relying entirely on heating systems, skylights can help warm the space by harnessing the sun’s natural heat and energy, reducing energy consumption and heating costs. 

4) Natural Ventilation

You may still be thinking about how to make skylights more energy-efficient. In this case, you can choose to install an operable skylight (also known as a retractable skylight) to further elevate your skylight energy savings. 

Installing an openable skylight allows you to open it either manually or electronically to let stagnant air leave the place and let fresh air in. This creates a natural airflow, ventilating your space thoroughly while reducing dependence on HVAC systems and energy costs.

Here are some further insights about skylights and their energy efficiency: 

1- Are skylights suitable for every climate? 

Yes, skylights are suitable for hot and cold climates, as they are designed and manufactured to suit climate conditions like excessive heat, strong rain, potential falling debris, and other factors. Skylights also integrate various features that help maintain suitable indoor temperatures, taking into account external weather conditions.

2- Can skylights cause a room to become too hot?

Yes. Skylight shape, material, size, and position are all factors that determine how well it can keep the room warm or cool. So a poorly selected or positioned skylight can surely make a room too hot. 

3- Do skylights require regular maintenance to remain energy efficient?

Yes, regular maintenance is essential for skylight energy efficiency, which can include cleaning glazing material, inspecting frames and seals, and checking for cracks, leaks, or other signs of damage.

4- Are skylights a good investment for commercial buildings?

Yes, installing a skylight is a great investment for commercial buildings, especially if you want to save costs in the long term. While the upfront price can be high, skylights reduce energy costs for ventilation, lighting, cooling, and heating, proving to be energy-efficient and cost-efficient in the long run.

Operable Skylights vs Fixed Skylights: Pros, Costs & How to Choose

Author skylights Categories Al-Mamary Blogs

Choosing between an operable skylight and a fixed skylight is not always a straightforward process. Each skylight type has its strengths and considerations, making them best suited for different spatial requirements, applications, and preferences. 

That being said, our guide provides you with a comprehensive breakdown of opening vs non-opening skylights, their pros and cons, and which is best for you—assisting you in making the right choice with confidence and ease. 

What is an Operable Skylight? 

Operable skylights, also known as opening or retractable skylights, are roof skylights that can be opened either manually or automatically, depending on how they operate. They allow natural light to fill the space while also promoting natural ventilation by releasing stale indoor air and letting fresh outdoor air circulate throughout the building.

  • How Do Operable Skylights Work? 

Retractable skylights come in two types: motorised (electric) and manual. Electric models operate via a wall switch or remote control, while manual models are opened and closed using a handle, crank, or control rod.

Discover more: What is an Operable Skylight? Advantages and Reasons to Install One

What is a Fixed Skylight? 

A fixed skylight, also known as a non-opening skylight, is a roofing solution that is permanently sealed and cannot be opened. The main function of this skylight type is to illuminate the indoors with sunlight without contributing to natural ventilation. Fixed skylights come in various sizes and shapes, all of which remain closed at all times. 

  • How Do Fixed Skylights Work? 

Fixed skylights have no opening mechanism, as they remain permanently closed. They simply allow natural daylight to pass through their transparent panels, with the light either diffused or kept clear depending on the material used.

Opening vs Non-Opening Skylight: Pros and Con

To fully leverage the benefits of skylight installation, you should carefully explore the pros and cons of opening vs. non-opening skylights so you can decide which is best for you:

Advantages of Opening Skylights

Wondering if you should install a skylight that opens? Below are some of the advantages of opening skylights: 

  • Natural Ventilation 

Retractable skylights’ biggest advantage is natural ventilation. When opened, they release hot air trapped near the ceiling while drawing fresh air into the building. When paired with open windows or doors, they create continuous natural airflow.

  • Improved Indoor Comfort 

Operable skylights elevate indoor comfort in several ways. The gentle, natural airflow created by an open skylight often feels more pleasant than the forced air from HVAC systems. They also help remove excess humidity and odours to keep the indoor environment fresher.

  • Better Air Quality 

Another advantage of opening skylights is improved indoor air quality. This is the natural result of releasing stagnant air, excess carbon dioxide, and odours, while helping to remove excess moisture and airborne pollutants.

  • Improved Energy Efficiency 

The use of operable skylights for ventilation and passive cooling significantly reduces reliance on HVAC systems, minimising energy consumption and lowering bills. 

  • Convenient Operation

Opening and closing operable skylights can be easily done using a remote control or a wall switch. Some advanced retractable skylights also feature sensors that automatically close as soon as rainfall begins. 

  • Supports Passive Cooling 

It is worth noting that retractable skylights are used for ventilation and passive cooling as well. As hot air escapes through the open skylight, cooler, fresh outdoor air replaces it, naturally lowering the indoor temperature without relying on air conditioning.

Disadvantages of Operable Skylights 

There are some disadvantages of operable and retractable skylights that you should consider, and they are as follows: 

  • Higher Initial Price

When it comes to the cost of retractable skylights vs fixed skylights, operable models are typically more expensive, as they integrate moving parts, opening mechanisms, and electrical components in motorised skylights. 

  • More Maintenance 

Operable skylights generally require more regular maintenance to inspect components such as hinges, seals, and motors, ensuring the opening mechanism continues to operate smoothly and efficiently.

  • Potential for Air Leakage

Since operable skylights have moving parts, unlike fixed skylights, they are more likely to leak air into the building if the movable components wear out or if the skylight is not installed properly. 

  • Greater Risk of Water Infiltration

Similar to the risk of air leakage, operable skylights have a higher potential for water infiltration if weather seals, flashing, or moving components become worn over time, or if the skylight is improperly installed.

  • Dependence on Power 

When exploring the pros and cons of opening vs. non-opening skylights, it is important to note that motorised, operable skylights need a source of power to operate. This can be an issue during power outages or electrical failures, although many skylight manufacturers address it with battery backup systems and other solutions.

  • More Complex Installation 

Considering how operable skylights work, they tend to have more complex installation processes than fixed skylights. But expert skylight installers ensure smooth and safe installation for reliable, long-term performance.

If those are the advantages and disadvantages of opening skylights, what about fixed skylights? 

Advantages of Fixed Skylights 

As part of our breakdown of the pros and cons of opening and non-opening skylights, it is crucial to grasp the fixed skylight benefits for well-informed decision-making. They are as follows: 

  • Maximised Daylight 

Fixed skylights are excellent skylights for natural light, as they fill the place with clear or diffused light, depending on the glazing material. The result is a bright, evenly illuminated interior with no glare and enhanced visual comfort.

  • Enhanced Energy Efficiency 

As fixed skylights light up rooms without using power, they reduce electricity consumption. This is a major fixed skylight benefit, especially in commercial and industrial buildings that operate for long periods of time or around the clock. 

  • Less Maintenance

Non-opening skylights have less maintenance needs than operable models because they do not contain moving parts. However, they still need regular cleaning and routine inspections of the glazing, weather seals, and other components to maintain optimal performance and longevity.

  • Improved Weather Resistance

Since fixed skylights are permanently sealed and have no sashes that open, they are less likely to leak water and air into the building. Meaning? Rainfall falls off the panels smoothly and easily while also protecting the indoors from unwanted air coming through gaps. 

  • Cost-Effective

Regarding the price of retractable skylights vs fixed skylights, the fixed models are more cost-effective, as they do not integrate opening mechanisms, motors, or moveable components. The price can be a major selling point for property owners looking for more budget-friendly options.  

  • Greater Durability

Another fixed skylight benefit is their great durability. While operable skylights are also quite durable, fixed types are more resilient and robust. Such strength is simply the result of having simpler construction and no moving components, so there are fewer parts that can wear out or fail over time. 

Disadvantages of Fixed Skylights 

There are some disadvantages that you should take into account when it comes to fixed skylights, such as the ones listed below: 

  • No Natural Ventilation

Unlike vented skylights, fixed skylights cannot be opened. Therefore, they do not provide natural ventilation or promote indoor airflow, meaning that indoor spaces rely more heavily on HVAC systems for ventilation instead of benefiting from natural air circulation.

  • No Passive Cooling 

Fixed skylights cannot release the warm air that naturally accumulates near the ceiling. So, they do not contribute to passive cooling. However, the right glazing delivers excellent thermal performance by reducing heat transfer and maintaining a comfortable indoor temperature.

  • Limited Functional Versatility

Fixed skylights are the ideal skylights for natural light, as they are installed to serve one primary purpose: bringing daylight into a space. But they cannot be used for ventilation or passive cooling, making them less functionally versatile.

  • Not Suitable for Ventilation-Dependent Spaces

Fixed skylights may not fit spaces heavily dependent on ventilation—think indoor pools, spa areas, bathrooms, kitchens, attics, and sunrooms. Those areas benefit more significantly from opening skylights to prompt natural airflow for a more comfortable environment and improved air quality. 

  • No Emergency Ventilation 

Fixed skylights cannot provide ventilation in cases of emergency like power outages and HVAC downtime. This is unlikely to be a concern in most applications, but it may be a limitation in spaces such as kitchens, bathrooms, lofts, or workshops, where natural ventilation is sometimes desirable.

As such, we concluded our opening vs non-opening skylights’ pros and cons breakdown. 

Operable Skylights vs. Fixed Skylights Comparison: Key Differences

Here is a brief and straightforward skylight comparison between operable and fixed skylights, demonstrating their key differences:

Fixed or Operable Skylights: Which Skylight Type Should You Choose? 

The skylight type that is best for you depends entirely on your needs and the building’s requirements. Below is a straightforward framework guiding your choice: 

  • Choose an Operable Skylight If You Need Ventilation

Operable models are best suited for kitchens, bathrooms, living spaces, and areas where humidity control is necessary, like laundry rooms, greenhouses, pools, and wellness facilities—to mention a few. 

  • Choose a Fixed Skylight If You Need More Natural Light

If daylight is the priority, go with fixed skylights. They are ideal for hallways, stairwells, living rooms, and spaces where ventilation is not a priority.

  • For Residential Projects

Operable and retractable skylights work well in homes where fresh air circulation is desired, while fixed skylights are sufficient for residential places requiring only natural daylight. 

  • For Commercial Buildings

Fixed skylights are best for areas needing only natural light, but opening skylights are best suited for buildings requiring natural ventilation as well for maximum comfort. 

  • For Hospitality and Luxury Spaces

Glass vs Polycarbonate Skylights

Glass vs Polycarbonate Skylights: Pros, Cons & Which to Choose

Author skylights Categories Al-Mamary Blogs

Are you planning to install a skylight but are unsure of which material is best for you—glass or polycarbonate? Is polycarbonate better than glass, or is it the other way around? Understanding the difference between these glazing options is essential for making the right choice with confidence and ease. 

Continue reading to explore our detailed breakdown of glass vs polycarbonate skylights, covering their advantages and disadvantages. While they are the standard in the industry thanks to their structural and compositional characteristics, choosing the glazing material that best suits your needs is what will help you get the most from your skylight.

What Are Glass Skylights?

Glass skylights are roof-mounted glazed openings designed to illuminate a building with crisp, clear natural light. They are characterised by excellent optical clarity, UV protection, scratch resistance, and other properties. 

Beyond their functionality, glass skylights are distinguished by their visual appeal, particularly when fitted with coloured glass. They are available in a wide range of shapes and sizes and can be manufactured using different glazing types to suit various architectural needs and performance requirements.

Glass vs Polycarbonate Skylights: Key Differences

Skylights are built to last you decades, so be sure to choose the right glazing material to support such longevity and reliability for years to come. Our glass vs polycarbonate skylight comparison below outlines the advantages and disadvantages of each type, exploring their unique features and how they benefit you. 

  • Durability 

Durability refers to the glazing’s ability to resist external factors without sustaining damage. That being said, both materials are highly durable but in slightly different ways. Glass skylights can endure environmental elements without yellowing or degrading with time, keeping their high-end appearance intact. They are also incredibly scratch resistant, so the surface retains its sleek look despite abrasive particles rubbing against the surface during cleaning. However, glass is less resistant to strong impact compared to polycarbonate. 

Polycarbonate skylights, on the other hand, are extremely resistant to high impact coming from hail, falling debris, and accidental impact, so they are very difficult to shatter and crack. In addition, they endure weather conditions and sun exposure, yet they are more likely to yellow or degrade with time. To counter this, specialised coatings are added to keep the material in good condition. Notably, polycarbonate is less scratch-resistant than glass, so it is your unique needs that determine which one is more suitable for you.   

  • Thermal Performance

One of the main benefits of skylights is their ability to regulate indoor temperature, keeping it warm in winter and cool in summer. Therefore, thermal performance is a key aspect of the glass vs. polycarbonate skylights comparison. Both glass and polycarbonate panels deliver satisfactory thermal performance—but there is more nuance to this statement. 

Glass generally offers superior thermal insulation, especially when manufactured as double- or triple-glazed units with Low-E (low-emissivity) coatings or insulating gas fills, reducing heat transfer and improving temperature control. To compare, multiwall polycarbonate sheets provide good insulation as well thanks to their internal air chambers, which are hollow spaces in-between layers, functioning like insulating barriers that slow down heat transfer. 

Nevertheless, glass thermal insulation remains stronger, positioning polycarbonate as a more practical choice for applications where heat control is not a primary concern, such as warehouses or agricultural buildings.

  • Light Quality

If you are debating whether or not glass or polycarbonate roofs are better for natural lighting, each option offers incredible daylighting, but in their own unique way. Glass skylights provide exceptionally clear natural daylight, allowing colours to appear more accurate. And since glass does not significantly diffuse sunlight, it maintains excellent optical clarity. However, this does not result in excessive glare, as glass is usually treated with features that help control glare and improve indoor visual comfort.

Polycarbonate skylights, on the other hand, fill interior spaces with soft, diffused natural daylight, creating more uniform illumination with fewer harsh shadows and reduced contrast. Unlike glass skylights, they scatter incoming sunlight, resulting in a lighting effect that is less direct and less optically clear. While the light is not as crisp or transparent as that provided by glass, its even distribution helps minimise glare and creates a comfortable, balanced indoor environment.

  • Weight and Installation

These are crucial elements when exploring the pros and cons of glass and polycarbonate skylights and roofs. Regarding weight, glass is significantly heavier than polycarbonate, especially double- and triple-glazed units. This means that glass roofs require stronger structural support to carry the load safely and efficiently. As a result, their installation process needs careful handling, and it tends to be more complex. 

On the contrary, polycarbonate is significantly lighter than glass, which is the case even with multiwall panels. Therefore, installation procedures are easier and simpler, and structural integration can be carried out without major reinforcements. Polycarbonate skylights, as such, can be installed on lighter roof structures that would not be able to handle glass skylights without lots of additional support.

  • Maintenance and Lifespan 

The comparison of glass vs polycarbonate skylights goes beyond installation and into their long-term needs and longevity. Glass skylights generally have a longer lifespan than polycarbonate skylights, typically lasting between 30 and 50 years, whereas polycarbonate skylights have an average lifespan of 10 to 15 years. 

Glass is a highly stable glazing material, meaning that it resists yellowing, weathering, and degradation, making its maintenance requirements relatively minimal. With regular cleaning, it retains its optical clarity, transparency, and premium appearance for decades. Meanwhile, high-quality UV-protected polycarbonate offers good resistance to weathering and long-term deterioration, too. However, its softer surface is more prone to scratching, so it requires more careful cleaning and upkeep. 

  • Appearance 

The glass vs polycarbonate skylights comparison also entails a general overview of both their appearances. Glass has a premium and superior look to it, especially with its luxurious finish, making it a highly sought-after option in modern architectural settings and elegant destinations. Coloured glass skylights featuring floral, geometric, or other designs are also breathtaking architectural statements that elevate the entire place to a new level of visual aesthetic. 

Polycarbonate skylights generally appear less sharp and optically clear than glass, particularly when multiwall sheets are used, making them perfect for practical applications, such as warehouses, factories, and industrial facilities, where durability and functional performance is prioritised over aesthetics. Although polycarbonate is not typically available in decorative coloured glazing like glass, it is offered in a range of finishes, including clear, bronze, grey, and opal, allowing different levels of light transmission, privacy, and solar control.

  • Cost 

Cost is the final aspect of our glass vs polycarbonate skylights breakdown, highlighting it as a crucial element for buyers to look into. It is worth mentioning that the exact cost of any skylight depends on the material, coatings, frame material, shape, size, and many other elements. That being said, glass skylight prices are generally higher than polycarbonate roofing solutions, due to the former’s greater weight and more complex manufacturing and installation procedures. 

Here is a summary of the differences between glass and polycarbonate skylights, outlining the key takeaways from the comparison above:

Differences between Glass and Polycarbonate Skylights
Differences between Glass and Polycarbonate Skylights
Key Difference Glass Skylights Polycarbonate Skylights
Durability Highly durable, extremely scratch-resistant Highly durable, incredibly impact-resistant
Thermal Performance Superior insulation, especially with coatings and insulating gas Good insulation, especially with multiwall sheets

Weight Significantly heavier, especially if double- or triple-glazed Not only lighter than glass, but also very lightweight in general
Installation More complex, likely to need additional structural support Simpler, less likely to need additional structural support
Maintenance Minimal needs Needs more maintenance
Lifespan Longer lifespan Shorter lifespan
Appearance More high-end, premium, and sleek looks. Preferred for aesthetic purposes Less clear than glass, used for more functional purposes
Cost Generally higher upfront cost Generally lower upfront cost

Considering all the above factors, which skylight material is best for you? 

Glass or Polycarbonate Roof: Which Should You Choose?

After having explored an in-depth analysis of both types, which one is best for you? The answer entirely depends on the spatial requirements of the building and the project. So, choose glass if you prioritise optical clarity, visual appeal, energy efficiency (double- or even triple-glazed), and long-term durability. Keep in mind that glass would require a bigger investment upfront. Nevertheless, glass skylights are best suited for homes, offices, hotels, retail places, and architecturally focused projects. 

Polycarbonate, on the other end, should be your pick when impact resistance is the priority. It is also perfect for lightweight structural loads, softer daylight, incredible design flexibility, and a more limited budget. Considering that polycarbonate is performance-driven, it is best suited for warehouses, factories, industrial buildings, sports halls, schools, and other large-span commercial applications.

Types of Glass Used in Skylights

Not all glass skylights are made of the same glazing material. There are several types of glass used in skylights, each one of them serving different functions and delivering various advantages. 

That said, there are two main categories for the types of glass used in skylights: the structural safety types and the performance types. Here is a brief overview of both of them: 

  • Safety Glass Types 

Standard (annealed) glass, typically used for windows, is not allowed for skylights due to safety requirements. Instead, building codes mandate the use of safety glazing, usually encompassing tempered glass and laminated glass. These two glass types are combined into a double-pane unit, working together as an integrated system to enhance both safety and performance.

  • Tempered Glass: This is heat-treated glass that is manufactured to be much stronger than standard glazing, making it incredibly resistant to heavy impact. This layer is the outer shield of the double pane, as it faces outwards.  
  • Laminated Glass: This pane consists of two layers of glass with a clear plastic layer (PVB) between them. If the glass breaks, the plastic coating holds the broken pieces together, preventing them from falling into the room. Laminated glass faces inwards, as it is the interior layer. 

This is the first type of glazing used in glass skylights, fulfilling safety requirements. Below is the second kind: 

  • Functional & Performance Glass Types 

These glass options are meant to handle lighting, heat, and other core functions. Such types include but are not limited to the following:

  • Low-E Glass: Glass treated with a microscopic metal oxide coating to keep the indoors cool during summer and warm in winter, achieving better energy efficiency. 
  • Gas-Filled Glass: This type of glass used in skylights is made of two or more panes of glass. Instead of air between these layers, a dense and non-toxic gas is added for slowed heat transfer. 
  • Tinted or Solar Control Glass: This glazing type is infused with coloured tones to minimise intense sun glare and limit heat gain, which is especially helpful with skylights in the UAE, for instance. 

If those are the types of glass used in skylights, what are their benefits? Why should you install a skylight for your home or commercial building? 

Glass Skylight Benefits

Glass skylights offer invaluable benefits for both form and function, transforming the way buildings are experienced. Here are a few glass skylight benefits:

  • Premium & Luxurious Appearance 

Glass skylights are considered the more high-end and fine option in terms of appearance when compared to skylights made of other materials like polycarbonate. This is mainly due to its refined and clearer appearance, which seamlessly integrates with modern architectural designs. 

  • Customisable, Coloured Designs 

The glass for skylights can be coloured and tinted, delivering uplifting hues that enhance the overall wellbeing and create a breathtaking look. Additionally, glass skylights can feature customised designs, including floral and geometric ones, for an exceptional architectural statement. This glass skylight benefit is highly sought after by property owners who prioritise aesthetics and visual appeal.

  • Clear Natural Lighting 

Skylights are mainly installed to provide natural lighting and reduce reliance on artificial light. Glass skylights, in particular, provide clear, natural, and crisp illumination. While some materials diffuse the light, glass keeps it clear and bright. Tinted glass, however, subtly alters the colour of the light but does not flood the room with obvious colours. 

  • Energy Efficiency 

Another glass skylight benefit is enhanced thermal performance. Glass skylights feature specialised glazing that maintains comfortable indoor temperatures, reducing reliance on HVAC systems for heating and cooling. They also minimise the need for artificial lighting by filling interiors with natural daylight. As a result, they lower utility bills and improve the overall energy performance.

  • Enhanced Safety 

All skylight types follow safety requirements, and glass skylights are no different. And with the way they are manufactured with laminated and tempered glass, they provide additional safety. Laminated glass helps keep broken fragments in place if the glass is damaged, while tempered glass is designed to break into smaller, less hazardous pieces. These safety features reduce the risk of injury and enhance the skylight’s safety and reliability long-term.

All these glass skylight benefits can be found in all types of glass skylights, which are explored below.

Types of Glass Skylights

There are various types of glass skylights, from which you can choose the most suitable one for your property needs, personal preferences, and long-term considerations. 

Here are some of the types of glass skylights you should look into: 

  • Fixed Glass Skylights 

Fixed glass skylights are completely sealed and remain permanently closed, meaning they cannot be opened for ventilation. As such, they function as overhead windows to the sky, with the primary purpose of bringing abundant natural light into a building without providing natural airflow. 

  • Operable (Retractable) Glass Skylights 

Operable glass skylights, also known as retractable skylights, can be opened and closed to let fresh air in and improve natural airflow. They can be operated manually or by using electric remotes. Some of them include rain sensors, allowing them to close automatically when needed.

  • Structural Glass Skylights

This type of glass skylight is integrated within the building’s structure, enabling it to support heavy loads like the wind, rain, snow, and high traffic. Structural skylights are not simply mounted into a roof opening like a window, but rather fundamentally incorporated into the building’s construction.

  • Custom Glass Skylights

A custom glass skylight is tailor-made for the property’s performance needs, spatial requirements, and shape preferences. The standard skylights are engineered with common features and have a more limited set of options when it comes to shapes, like conical skylights, dome-shaped skylights, barrel-shaped skylights, and pyramid shapes. 

Custom glass skylights, on the other hand, are made to fit custom dimensions. They also come in a variety of configurations and feature tailored glazing and performance functions. This type is best suited for unique projects like commercial glass skylights inserted into unconventional and irregular spaces.

Knowing the benefits of glass skylights, how are they installed? Below is a step-by-step breakdown of glass skylight installation. 

Glass Skylight Installation: Step-by-Step

Glass skylight installation follows a structured implementation process, ensuring efficient insertion for long-term reliability, safety, and excellent performance. While the specifics of installing a residential or a commercial glass skylight vary depending on the project’s niche requirements, here is the general installation workflow: 

  • Roof Assessment & Skylight Planning

The glass skylight installation process begins with a thorough assessment of the roof structure before any physical work takes place. This evaluation ensures the roof can safely support the skylight by examining its load-bearing capacity, slope, and insulation layers. During the assessment, experts also identify the most suitable location for the skylight to achieve optimal performance and best sunlight exposure.

Once the assessment is complete, professionals proceed to plan the skylight’s size, design, and shape, taking into account their findings from the earlier inspection. The planning stage aims to ultimately achieve smooth integration and efficient insertion in later stages of the process. 

  • Structural Opening & Base Preparation

The second phase includes cutting a precise roof opening according to the previously finalised skylight design and measurements. The opening must accommodate the skylight perfectly to ensure seamless integration, and it is created by cutting through the roof’s material and the underlying layers. 

After this opening is ready, the surrounding structure is reinforced to protect the roof’s structural integrity. So, additional framing is installed around the opening to distribute loads evenly and keep the structure solid and secure. These enhancements ensure overall safety and durability. 

  • Placing the Frame & Installing the Panels 

Next in the glass skylight installation process comes the actual insertion of the glazing unit. But before the glass panels are put in place, the skylight frame is first positioned within the roof opening. This frame serves as the structural support that holds the glazing system and anchors it to the roof, making it essential for the frame to be installed first. 

Now, the glass units are lifted into place and fitted within the installed frame according to precise alignment and safety specifications. Then, experts ensure that the panels are positioned well for the best insulation performance, structural integrity, and long-term durability. 

  • Weatherproofing & Flashing

When installing residential or commercial glass skylights, professionals carry out weatherproofing and flashing to prevent water and air leakage. These processes are crucial for proper sealing and protection against damage and environmental impact, enhancing the skylight’s reliability, longevity, and performance. 

Weatherproofing seals the skylight’s area completely by applying waterproofing membranes around its edges and surrounding roof material. Flashing, however, involves installing thin layers of metal around the skylight’s frame to direct rainwater away from the opening. Combined together, they protect the glass skylight from leaks and weather exposure. 

  • Interior Finish 

The last step of the glass skylight installation process is the interior finish, which is concerned with the area around the skylight but from inside the building. This same area is integrated seamlessly with the roof’s or ceiling’s design, resulting in a finished and effortless look. The process may include adding drywall, refining edges, and installing insulation around the opening.

These skylight benefits cannot be obtained without proper installation. So, how is installation handled? 

How to Install a Skylight: The Process Step-by-Step 

How should a skylight be installed? Here are the exact steps of how to install a roof skylight​, as followed by professionals, and what each of them entails: 

  • Step 1: Assessment and Planning 

During the first stage of skylight installation, experts make an in-person visit to your property to determine the roof’s suitability. They inspect its type, framing, load-bearing capacity, and steepness to decide whether or not it can handle skylight installation safely. Then, they proceed to identify and plan the most suitable location for the skylight, which is decided by various factors, including: 

  • Orientation: The direction that the skylight faces, influencing light quality. 
  • Sizing: An initial estimation of the size must be defined to avoid excess heat and glare. 
  • Mechanical Systems: The chosen spot must be clear of obstructions like plumbing stacks, electrical wiring, and HVAC ducts. 
  • Desired Aesthetics: The skylight’s final look is taken into consideration for efficient installation and maintained aesthetic appeal.

Additionally, the assessment considers structural and regulatory requirements such as wind load zones, thermal performance targets, and full compliance with local building codes including Dubai Municipality regulations, UAE Fire & Life Safety Code, Estidama Pearl Rating, and Al Sa’fat requirements. Fire-rated glazing and smoke ventilation integration (AOV systems) are also evaluated where applicable, particularly for commercial projects. At the end of this stage, professionals choose the optimal location for the skylight on your roof.

  • Step 2: Choosing the Skylight 

Choosing the right skylight for your home or commercial place is just as important as the skylight installation process itself. Based on spatial requirements, personal preferences, and safety standards, professionals help you decide on the best skylight for you. They consider the following aspects: 

  • Type: Includes exploring structural and non-structural options as well as retractable and fixed skylights.
  • Shape: Skylights come in various shapes like cones, domes, barrels, and pyramids, or they can be completely flat. 
  • Size: Choosing the right skylight size is based on structural load considerations, long-term durability, and installation requirements. 
  • Glazing: This refers to the skylight materials used within the skylight frame and plays a key role in thermal, visual, and safety performance. To choose the right glazing materials, many factors have to be considered, such as thermal insulation, solar heat control, and natural light transmission, among others. 
  • Framing: You should decide on the proper material for the framing, which supports the roof opening holding the skylight in place. 
  • Design: Some skylights feature artistic designs of floral arrangements, geometric shapes, or coloured glass. Let professionals know of your vision to help actualise it.

Choosing the right option for your place makes the entire skylight installation process easier and more streamlined.

  • Step 3: Marking the Roof Opening

Having decided on the suitable skylight and its location on the roof, the opening is first verified in accordance with the original approved shop drawings of the building to ensure full design coordination. Based on these references, experts then mark the opening on both the interior ceiling and the exterior roof surface. This outline transfers the approved measurements into the property, guides the upcoming work, and maintains accuracy and alignment, ultimately reducing the risk of errors and structural damage. This opening is also designed to optimize daylight usage, achieve visual balance, and prevent excessive heat and glare. After outlining the opening, experts ensure that the interior ceiling markings align exactly with the exterior roof markings, preventing any mismatch.

  • Step 4: Cutting the Opening 

Once the skylight position has been marked on both the ceiling and the roof surface, a small pilot hole is drilled from inside the building to verify alignment. This hole acts as a precise reference point that helps installers confirm accurate correspondence between internal and external markings before any major cutting begins. 

Once alignment is validated, the layers of the outer roof are cut. This includes cutting tiles, shingles, and metal sheets using the appropriate tools and following the best practices. Then, the roof deck is cut along the marked lines. Finally, installers remove all loose materials, clean the opening, and inspect it one more time to ensure accuracy. 

  • Step 5: Framing and Reinforcement 

At this stage of skylight installation, experts carry out structural work within and around the roof opening to strengthen it where needed, ensuring it is solid and durable enough to support the skylight properly. As such, framing refers to the process of building a structural border around the opening after the roof is cut. It can be built of different materials, all of which support the opening, distribute the roof load across the entire hole, and solidify the overall structure for future maintenance. 

As for reinforcement, it involves enhancing the surrounding roof structure to make up for the lost material and structural support due to cutting the opening. The needed reinforcements can include adding extra beams and reinforcing nearby rafters or joists. This step of how to install a skylight ensures a smooth and safe transition to the next stage. 

  • Step 6: Installing Flashing and Underlayment 

Underlayment is a protective, waterproof layer installed around the skylight opening to prevent water leaks. It is applied after the opening is cleaned and once the roof structure is reinforced, creating a reliable base for this layer. Once in place, the flashing system is installed. It is typically made of thin metal pieces fitted around the skylight edges, directing water away from the opening.

In a complete skylight installation system, additional detailing is also considered to ensure long-term waterproofing and performance. This includes an upstand kerb around the opening to provide a raised structural base, a waterproofing membrane (bituminous or liquid-applied polyurethane) to create a continuous moisture barrier, EPDM gaskets for enhanced sealing, counter-flashing to protect exposed edges, structural silicone seals for airtight joints, and thermal break details to reduce heat transfer.

Together, these components, along with flashing and underlayment, form an integrated protection system that safeguards interior spaces, enhances durability, and ensures the long-term performance of the skylight installation. Notably, skylight installation in hot and dry climates like the UAE still requires these layers to address occasional rainstorms, dust protection, and condensation control caused by temperature variations.

  • Step 7: Fitting & Sealing the Skylight Unit

Once the opening is fully prepared, the skylight system is installed as part of a complete engineered assembly rather than a simple placement process. The unit is positioned and integrated according to the manufacturer’s approved installation system, ensuring proper alignment with the supporting frame or upstand kerb. Fixings and brackets are applied as specified in the system design to secure structural stability, while all joints and interfaces are sealed using appropriate waterproofing and air-sealing methods to ensure full system performance. This controlled installation approach ensures weather resistance, structural integrity, and long-term durability.

  • Step 8: Interior Finishing & Final Inspection 

After installing the skylight, experts finish the ceiling area around it to ensure a seamless integration with the interior space. This involves installing finishing elements such as flashing, trims, and drywall around the opening, along with painting and other detailing works, ensuring an elegant appearance and a fully functional structure. Finally, installers inspect the skylight, checking its alignment, sealing quality, and water drainage performance, along with overall finishing, to verify that everything is installed properly and efficiently.

Now that you know the exact steps of how to install a skylight, does the process differ across residential and commercial buildings? 

Commercial and Home Skylight Installation: What’s the Difference? ​

Commercial and home skylight installation typically follow the same steps but have slight differences and varying considerations. On the one hand, home skylight installation usually implies smaller openings, simpler framing, faster procedures, and minimal disruptions to daily home use.
