What is the Best Type of Glass for Skylights?

Choosing Glass for Your Skylight

Skylights are a lovely addition to your home; they let in sunlight and have the added novelty of seeing the sky right over your head. Skylights allow natural light to brighten a room or give you an opportunity to stargaze from the comfort of your recliner. But what type of glass should you choose?

Safety Requirements

Building codes require specific types of glass for skylights:

• Tempered glass on the exterior (weather side)
• Laminated glass on the interior side
• This combination ensures safety if the glass breaks

Energy Efficient Options

For our Ottawa Valley climate, consider these energy-saving features:

• Low-E coating – Reduces heat transfer and UV rays
• Double or triple glazing – Better insulation
• Argon gas fill – Improved thermal performance
• Tinted glass – Reduces solar heat gain

Glass Tints and Coatings

Depending on the skylight's location and your needs:

• Clear – Maximum light transmission
• Bronze tint – Reduces glare and heat
• Grey tint – Subtle light reduction
• Reflective coating – Best for hot, sunny rooms

Maintenance Considerations

Choose glass with easy-clean coatings if your skylight is difficult to access. Self-cleaning glass uses UV rays and rain to break down and wash away dirt.
