The Trentham Range of Stormproof Windows

Our timber stormproof casement windows are designed to offer greater protection with advanced performance and maximum security. They offer higher energy/insulation values and noise reduction levels than standard flush casement windows.

Sometimes referred to as lipped casement windows, the stormproof design features a rebated casement opener which lips over the outer face of the window frame – protecting your home from the elements.
