/ SASH WINDOWS

SASH WINDOWS

Windows with vertically moving sashes are called “Sash Windows”.

Modern mechanisms have made sash windows as practical and safe to use as they have never been before.

Besides being used in period buildings, sash windows are also employed in new residences for the sake of practicality and architectural concerns all around Europe.

A modern mechanism, consisting of stainless steel springs placed in a pipe of 16-26 cm diameter is able to move a 45 kg sash simply by your fingers and to leave it at any position you like.

We use high technology spring balances in keeping the balance of sashes at any point of its movement. We also produce timber box sash windows. These are traditional vertical sliders working with weights and cords.
