Timber Sash Windows

We understand replacing your windows is one of the biggest purchases in when improving your property. You want to ensure what is installed will not only look the part, but will last the test of time. This is why we replace the whole window and frame rather than restoring the existing box.

Our timber sash windows come in a choice of engineered hardwood or Scandinavian slow grown red wood, to ensure strength and durability. The windows benefit from A-rated argon gas filled glazing and neoprene seals to all joins, eliminating cold and draughts. Our products come factory sprayed with micro-porous paint; because of this we are able to offer a 10 year guarantee on the paint finish.

Spiral Balance

Spiral balanced windows were introduced back in the 80’s as an alternative more economical method of operation. Sashes are fixed to a spring tension spiral and operate on friction. Although this method got off to a shady start they have been vastly improved over the years and have superseeded cord and weight as the preferred mechanism. 

This modern day alternative of the classic box sash window reproduces the original charm and character of English sash windows and incorporates all the traditional features of an original box sash window with a modern method of operation.

Cord & Weights

The Sliding Sash Cords & Weights window is a vertical sliding sash, incorporating a traditional pulleys and weights lifting system. The Cords & Weights design utilises a heavy weight nylon cord on self-lubricating wheels to operate the window. This profile is particularly suited to stone or brick new build mansions and prestigious refurbishments. Our Cords & Weights Sliding Sash window ensures the traditional character and charm of a period building is maintained, whilst incorporating the latest advances in timber window technologies, security and performance for 21st century living.
