Flush casement uPVC windows are a stunning and timeless window that can be used on a wide range of properties to provide a truly authentic finish to almost any building. These windows have a sash, otherwise known as an opener, that is flush with the outer frame, hence the name flush casement. Our windows are elegant in design with authentic aesthetics and provide an excellent alternative to timber which won’t need any repainting or costly maintenance.
Flush casement UPVC windows can be used for grade listing buildings, areas needing planning permission, heritage properties and conservation areas. The windows are designed to replicate the appearance in this type of period property and add a traditional feel to older properties that may need uplifting or renovating.

Although these windows were designed for older properties, they are equally in demand for newer buildings which may feature a traditional or modern design. This outlines the variety of properties this window is suitable for and shows the versatility of our flush casement windows.

Most special colours have a grained texture to replicate timber appearance. However a few have a smooth texture so if you are looking to replicate aluminium or just want a more modern look then smooth finishes would be perfect.
There are 4 cill sizes and the one you select will depend on whether you will be mounting your windows on a stone cill or directly into the aperture. If you have a stone cill then the 95mm stub will be most suitable and if not then the 150mm/180mm will be most practical as they will allow you to set the windows deep enough whilst taking the rainwater away from the brickwork.
