Sash Seal is a spring device designed to improve the seal of a sash at the hinged side of a window. It consists of 1 acetal moulding and 1 spring steel component designed to universally fit all 13mm and 17mm stack height systems.
The simple act of closing the window causes the unique Sash Spring to push against the Frame Wedge to ensure an efficient seal.
Locate the components on the stay fixing area as shown in both diagrams. This position is a universal fixing point and will enable the Sash Seal to be used on all PVCu, Aluminum, and Timber frames. One Sash Seal set will give adequate seal if fixed centrally on the hinge stile.
