What are Flush Casement Windows?

Flush casement windows are a type of window where the opening window (the casement) sits flush with the frame, giving a flat and clean appearance. Appealing to all kinds of homes this type of windows gives a timeless feel to your home complementing traditional and modern style homes. This is in contrast to regular casement windows where the casement protrudes from the frame. Flush casement windows were traditionally made from timber, but our modern flush casement windows are made from uPVC and aluminium which are highly durable and weather resistant materials. Unlike timber windows, our flush casement windows won’t crack, rot or fade when exposed to harsh weather conditions. 

The distinctive features of flush casement windows include their sleek, flat appearance, their energy efficiency, and their versatility in terms of colour and finish options. They are also known for their excellent weather resistance and durability.
