Vari Vent Sash Windows

This is a window which we have designed and developed ourselves, and to our knowledge we are the only company in the world that manufactures this window.

Primarily it looks like a vertical straight slider but for ease of use and to obtain maximum ventilation, the top sash opens outwards on stainless steel friction stays and the bottom slides vertically and tilts inwards.

The bottom sash is fitted with two 100mm slide bolts, so that the bottom sash can be secured whilst the top sash is open. When completely closed, the sashes are secured by a locking casement fastener.
