What Is A Flush Casement Window?

29th September 2020

Flush casement windows consist of a sash which sits flush with the window frame, creating a flat surface from an outside perspective. This creates a seamless and elegant design that can give an older property a modern makeoverbut also suit contemporary properties perfectly.

The flush casement was first designed to replicate the aesthetic of timber windows but to provide the modern functionality of other materials. Flush casement windows are available in uPVC and aluminium and serve as the cost effective choice over timber windows as well as having advantages in thermal efficiency and durability.

The flush casement window is ideal for someone looking to replace timber windows but would like to be rid of the high maintenance for a virtually maintenance free option with minimalist design.

Benefits of flush casement windows

This type of window is a more cost effective option to timber windows as mentioned before, and in addition to this, they are easy to maintain and clean – no need to sand and paint them every few years as you would need to do with timber windows. Just a quick wipe every now and then will keep them in pristine condition.

Flush casement windows are all high energy rated and highly secure. You are also able to customise the design to suit your personal taste with a wide variety of styles, colours and finishes available to accommodate you.

Seen above, the Deceuninck uPVC flush window has superior sound insulation, slim and aesthetically pleasing profiles, and a long and useful lifespan with minimum maintenance.
