Spiral Sash Balances

The Ellipsis range of spiral sash balances are designed for use in both conventional vertical sliding windows and vertical sliding windows with a tilt-in-facility, together with serving hatches and counter screens.

Spiral balances are in use throughout the world in PVC-U, aluminium and timber windows. They are designed to counter balance a sash, holding it in any position. Whilst balances are not designed as a mechanical opening device, they do give a degree of assistance when operating the window.
