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.

What some of our customers have said

The craftsmenship of the windows supplied by glyngary were second to none, finish was absolutely impeccable.
I was quite nervous about switching to a new supplier as my livelihood relies on the quality they produce.
I can quite happily say it was the best move i ever did, they make my job so much easier with the fine quality of products they produce.

Thanks again J. Holingworth – Hollingsworth Windows and Doors Ltd
