Types of Double Glazing Glass

Energy Efficient Glass

This type of glass has a special coating that reflects heat back into the room. This reduces heat loss and lowers energy bills.

Noise Reduction Glass

This glass uses extra thick glazing and laminated layers to block outside noise. It is ideal for homes near busy roads or airports.

Safety Glass

Safety glass is tempered for added strength. When broken, it shatters into small, blunt pieces rather than dangerous shards.

Self-Cleaning Glass

This glass has a special coating that uses UV light to break down dirt. When rainwater hits, it takes the loosened dirt with it.

Solar Control Glass

This glass partially blocks solar radiation from entering your home. It saves on cooling costs and prevents furniture fading.

Decorative Glass

For a unique look, decorative glass comes in styles like frosted, coloured, etched, or patterned.
