Our uPVC window and door frames have a high BAL rating of 40, are self-extinguishing and will not ignite.

Tilt Turn Window & Door Function

The unique and flexible tilt turn option functions like a normal swing out window or door, but with the added benefit of locking at the base to create a fixed opening at the top. This allows for simultaneous hot air release and cool air intake, and provides added security whilst the window or door is open.
