Sash window on spiral balance

SASH WINDOWS are traditional constructions found mainly in Great Britain and Ireland and Northern France. Windows of this type operate in an up-down sliding system. 

In sash windows we use cords and weights, which are placed on both sides, and the whole piece is finished with internal and external lintels. Each window is equipped with an access pocket that allows access to the weights in the mounted window. 

We also offer sash windows on springs located in the sashes. This reduces the window frame size and therefore increases the amount of light.

The windows are fully equipped with rollers, fitch fasteners, lifts and rings.

The characteristic external horns and the possibilities of making wooden, astragal bars refer to the traditional style of the windows.
