Casement windows may be the standard modern window system today, but SashLine’s window units are far from ‘standard’. We manufacture and install bespoke casement windows to any dimensions in any of five woods, decorated to any RAL code colour or stained to perfection to bring out the true beauty of the natural wood.

Traditional French doors have never looked so good or been so affordable. SashLine manufactures Victorian, Edwardian, Georgian and contemporary style French doors for clients who are looking for an elegant addition to their home, and developers and main contractors seeking a company that can deliver on quality, volume and price.

Bifold doors add a touch of flair and enhance the value of any home. A whole wall of glass doors that slide and fold effortlessly to one side to provide a seamless transition from inside to outside, extending living spaces into garden spaces for entertaining or relaxation.

At SashLine we recognise the importance of aesthetic authenticity, so we offer a service where any original window can be meticulously replicated for homeowners or contractors. We can help you obtain planning permission to install our timber conservation windows, so they can improve the energy efficiency of your home while retaining the traditional elegant look of your property.
