Flat Sash Aluminium Windows

This was a really interesting project to work on, with flat sash aluminium windows in grey and white being installed.


This particular installation was in Cheam

Products Used

Flat sash Aluminium windows have been installed. At the front of the property they are grey on the exterior with a white interior to increase light within the home. They also have square lead glass.

At the back and side of the property they have a white exterior as well as interior, with clear glass. We also installed a stained lead design, which looks really effective.

Aluminium windows are growing in popularity. They come in a wide range of styles, colours and designs to suit almost any property and have slim sight lines. They offer modern security, thermal performance and virtually no maintenance.
