Everest uPVC Sliding Sash Windows offer the following benefits...

Easy to use and maintain

Easy to use and maintain

Everest uPVC Sash Windows feature spring balances so the window can be lifted with minimum effort. The durable uPVC will never rot, rust, peel or flake, and they even come with the option of self-cleaning glass. The tilt-in-hinge design makes cleaning the outside of the window from inside extremely simple.



Everest uPVC Sash windows are made with top of the range weather resistant materials and designed to ensure your home stays free from draughts. This means they retain more heat than traditional timber sash windows giving them a B-rating for thermal performance.



The multi-chamber profile, 16mm Argon-filled gap within the double glazing and interlocking sashes in our uPVC sash windows help keep out unwanted noise.

Greater choice

The key-lockable traditional style fitch lock is secured into a galvanised steel reinforcement for additional rigidity and security meaning it meets the British Standard for security. And there is an optional restrictor to limit opening to allow for secure ventilation.
