Spiral Balance Vertical Sliding Windows | Timber Windows

IDEAL FOR SMALLER REVEALS

Concealed spiral balance sliding sash windows are a great alternative to cords & weights and slide & tilt options.

Combining period style with modern technology, spiral balance sash windows are great because they can be fitted into smaller reveals. The sashes slide by means of partially hidden pre-tensioned springs, with a smooth, easy-to-use mechanism that’s simply a joy to use.
