When you're considering adding a skylight to your home, one of the most crucial decisions you'll face is choosing the right type of glass. The glass you select can significantly impact your skylight's performance, energy efficiency, and overall aesthetics. In this comprehensive guide, we'll explore the various types of skylight glass available, helping you make an informed decision that best suits your needs and preferences.
What is Skylight Glass?
Before we dive into the different types, let's briefly touch on what skylight glass actually is. Essentially, it's a specialised type of glass designed specifically for use in roof windows and skylights. It's engineered to withstand various weather conditions, provide insulation, and allow natural light to filter into your home.

Types of Skylight Glass
Now, let's explore the different types of skylight glass you can choose from:
Clear Glass
Clear glass is the most basic and common type of skylight glass. It allows maximum light transmission, making it an excellent choice if you're looking to brighten up a dark room. However, it offers minimal heat control, which might be a concern in certain climates.
Tinted Glass
If you're worried about excessive heat or glare, tinted glass might be your solution. It comes in various shades and can reduce heat gain and UV radiation. While it slightly reduces light transmission, it can create a more comfortable indoor environment.
Tempered Glass
Safety is paramount when it comes to skylights, and tempered glass addresses this concern head-on. It's heat-treated to be significantly stronger than regular glass and, if broken, shatters into small, relatively harmless pieces rather than sharp shards.
Laminated Glass
Another safety-focused option is laminated glass. It consists of two or more panes of glass with a layer of polyvinyl butyral (PVB) between them. This design makes it highly resistant to breakage and, if it does break, the PVB layer holds the glass pieces together, reducing the risk of injury.

Low-E Glass
Low-emissivity (Low-E) glass is coated with a microscopically thin, transparent layer of metal oxide. This coating reflects heat while allowing light to pass through, making it an energy-efficient choice that can help reduce your heating and cooling costs.
Reflective Glass
Reflective glass has a metallic coating that reflects both light and heat. While it's excellent for reducing heat gain and glare, it also significantly reduces light transmission. It's typically used in commercial buildings or homes in very hot climates.
Insulated Glass
Insulated glass units (IGUs) consist of two or more panes of glass separated by a space filled with air or gas. This design provides excellent thermal insulation, making it a popular choice for energy-efficient homes.
Self-Cleaning Glass
For those hard-to-reach skylights, self-cleaning glass can be a game-changer. It's coated with a photocatalytic and hydrophilic layer that uses sunlight and rain to break down dirt and wash it away.
Factors to Consider When Choosing Skylight Glass
When selecting your skylight glass, there are several factors you should keep in mind:
Climate and Weather Conditions
Your local climate plays a significant role in determining the best glass for your skylight. In hot climates, you might prioritise heat-reducing options like tinted or reflective glass, while in colder regions, insulated or Low-E glass might be more beneficial.
Energy Efficiency
If reducing your energy bills is a priority, consider options like Low-E or insulated glass. These can help maintain a comfortable indoor temperature year-round, potentially lowering your heating and cooling costs.
Safety and Durability
For peace of mind, prioritise safety features. Tempered or laminated glass can provide added protection against breakage and potential injury.
Aesthetic Preferences
Don't forget about the visual impact of your skylight. Clear glass might be your preference if you want to maximise natural light, while tinted glass can add a subtle colour to the light entering your space.
Budget
While it's tempting to opt for the most advanced glass type, it's important to balance your needs with your budget. Some specialised glass types can be significantly more expensive than basic options.
Installation and Maintenance Tips
Once you've chosen your skylight glass, proper installation and maintenance are key to ensuring its longevity and performance:
Professional Installation
We always recommend professional installation for skylights. Proper installation is crucial for preventing leaks and ensuring optimal performance.
Maintenance Tips
Regular cleaning and inspection of your skylight can help prevent issues. For most glass types, a simple solution of mild soap and water is sufficient for cleaning.
Dealing with Common Issues
Be aware of common skylight issues like condensation or seal failure. If you notice any problems, it's best to address them promptly to prevent more serious damage.
The Bottom Line
Ultimately, choosing the right skylight glass can significantly enhance your home's natural lighting, energy efficiency, and overall comfort. If you consider the various types available and factoring in your specific needs and local climate, you can make an informed decision that you'll be happy with for years to come.
