Timber Flush Casement Bay Window with SGU

ATW has refined its casement windows to exceed expectations of customers and requirements for the UK market, climate and traditional style. We offer several styles of casement windows:

– Flush style casement with a 92 mm frame OPENS OUT

– Storm-proof style casement with a 66mm frame OPENS OUT

– Pivot style casement with a 68mm frame OPENS by ROTATION

– Tilt and Turn European style casement which is the only one that OPENS INSIDE.

The Flush style is by far the most popular in the UK as it is perhaps the most traditional or most common.  Technical Drawings are available on request for your project.

Of course if you need something different to what you see here, we can completely custom make products for you, if you can provide some photos and dimensions, we will make a technical drawing for you to amend or approve as you like.
