Energy Efficient Flush Casement Windows by SolarFrame • SolarFrame

Flush Casement Windows

Flush casement windows offer the aesthetics of a pre-1932 timber window but with 21st century thermal benefits.

Offering both contemporary and traditional looks, flush sash windows can be foiled to have a woodgrain appearance. They are ideal in conservation areas or where the need to replicate timber is a must. You can however go for a modern appearance with a smooth grey finish, ideal for updating homes or for new build properties.

Whatever look is chosen for our flush casement window, enhanced security is a priority with our full range of high-performance hardware. From handles to locking mechanisms, hinges to accessories, all will perfectly complement the look you want to achieve.

Timber Replica

Paired with a woodgrain foil, our flush casement windows have the appearance of traditional timber windows, with modern thermal efficiency.

Flush Fit

The sash fits snug within the frame,
which means the windows have a completely
flush appearance.


Multi-chambered technology means our windows ensure the warmth stays inside your homes. They're also fully recyclable at the end of their lifespan!
