Heritage Flush Sash Windows

Our Flush Sash casement windows have been designed to replicate the appearance of traditional timber casement windows. A flush casement is defined by their ability to close into the outer frame giving a flat appearance. These windows combine the elegance and style of traditional timber with all the added thermal and security benefits of PVC.

Much like their wooden counterparts, the PVC flush casement windows tend to have equal sightlines (frames of the same width). This look is achieved by using dummy sashes for any non-opening casements. The purpose of this is to keep a balanced look to the whole of your property which undoubtedly improves the overall appearance of a property.

This range is ideal for those who wish to add or improve a period property. It’s unique aesthetic appearance make it one of the most attractive, affordable windows currently on the market.
