Mechanisms

Our timber sash windows are available with two distinct mechanisms: spiral balance or cords and weight mechanisms.

Spiral Balance

Spiral balanced windows were introduced back in the 80s as an alternative, more economical method of operation. Sashes are fixed to a spring tension spiral and operate on friction. 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.

CORDS AND WEIGHTS

The sliding sash cords & weights window is a vertical sliding sash, incorporating a traditional pulleys and weights lifting system. This 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.

Sash Window Horns

We offer three classic horn designs that will complement the traditional character of your sash windows. Sash horns extend from the lower corners of the top sash and were originally an integral detail of a sash window, used to strengthen the structure. Nowadays, sash horns feature solely for aesthetic purposes.
