Flush Casement Windows, Kent

Affix Windows supply and install uPVC flush casement windows to homeowners in Sidcup, Blackfen, DartfordBexleyheath, WellingBromley, Chislehurst, and other surrounding areas of Kent and London.

Flush casement windows (otherwise known as flush sash windows or flush sash casement windows) combine a traditional aesthetic with modern design to offer a beautiful window. These windows capture the look of traditional timber joinery, allowing them to be a wonderfully traditional addition to any home in Sidcup.

Although Kent flush casement windows can be coloured to replicate timber, they are actually manufactured from uPVC. Operating much like a casement window, our flush casement window system offers an incredibly easy to use and practical design. This includes open out sashes that allow for increased ventilation without encroaching on living space.
