Everest Timber Sliding Sash windows come with the following benefits...

Greater choice

Greater choice

You can select the authentic cords and weights mechanism, or opt for the modern twist on sash windows with spiral balances; hidden springs that ensure the window opens smoothly. You can even choose from 10 different finishes, the colour of the traditionally styled fitch locks and, for real character, add Georgian bars. There is also the option of a side hung bottom sash for easy cleaning on windows featuring the cords and weights system.



Everest Timber Sash Windows maximise heat retention in your home using modern technology like low E glass, draft-resistant seals, and a 14mm Argon-filled gap combined with traditional solid timber material. They're also made-to-measure to ensure a perfect fit and the locks engage securely at the interlock to create a tight seal.


Softwood and hardwood options

Softwood and hardwood options

Our timber sash windows are available in two types of wood, softwood or hardwood. Our softwood timber frames use European Redwood, which can be finished in a range of paints. Our hardwood windows use Red Grandis, and are available in a range of grained and painted finishes.


More secure

More secure

Everest Wooden Sash Windows are designed to ensure your family and possessions are protected with an internal security bolt and key lockable fitch style locks. In addition the glazing bead is secured with concealed fixings. Safety glass is also fitted as standard within 80cm of the floor.

Guaranteed for 30 years

Guaranteed for 30 years

Our timber sash windows come with a 30 year guarantee against rot and fungus, a 10 year guarantee on the whole window and installation, and a 5 year guarantee on the paint and stain finishes.



Solid timber acts as a natural soundproof barrier to reduce noise disturbance and is further enhanced by sashes that engage snugly into their channels.
