Thermal Glass

We offer Thermal glass with all of our Composite doors.

All of or glass patterns that you can find on our Composite Door Designer are available with Thermal glass upgrades. 

However Thermal glass upgrades are not available on our triple glazed units. The reason for this is that triple glazed glass offers very similar benefits to those offered with Thermal glass.

Composite doors fitted by us with Thermal glass are rated as A rated glass.

How Does Thermal Glass Work?

Thermal glass can keep your home warm in the winter months whilst keeping your house cool during the summer.

The Thermal glass allows visible light to enter through it into your home, whilst at the same time keeping heat from passing through the glass.

During the colder months, the heat produced inside of your home is sealed inside.

During the warmer months, the heat from outside is prevented from entering your home.
