Energy Efficient

We can offer you ‘A’ rated and triple glazed windows, featuring the most technically superior glass available today, with U Values as low as 0.8.



Toughened glass can be a cost effective way to enhance security. Laminated glass is even stronger, but is more costly.


Our range of obscure glass offers you varying levels of privacy and a choice of designs.


Toughened glass is stronger and safer than normal glass. When it breaks it shatters into tiny fragments as opposed to dangerous shards of glass. We fit toughened glass as standard on all doors and windows below 800mm from floor height.

Self Cleaning Glass

Self cleaning glass has a titanium dioxide coating, which makes the glass very flat, this makes it harder for dirt to stick and causes water to sheet down and clean the glass. UV filters integrated within the surface coating, break down organic dirt such as bird droppings which enables it to be washed away (hydrophilic action).

Increased Privacy with Obscured Glass

Our range of obscure glass offers you varying levels of privacy and a choice of designs. There are over twenty designs to chose from, they all vary in their obscurity. Below are eight of the most popular choices. Call 01275 878153 to discuss with our helpful team.
