Casement Window Features
We offer an extensive range of colours and wood effects across our casement window range. Thanks to our in-house spraying facility, we are able to supply uPVC windows in over 250 RAL colours.
Low sightline grey gaskets are installed into our window design to ensure enhanced weatherproofing, protecting your home from draughts and extreme weather.
We install Warm Edge spacer bars in conjunction with low emissive glass into all of our casement windows. Spacer bars are used to prevent condensation, overall greatly contributing to the products durability and window energy performance.
With an eye for detail, all of our casement windows feature a traditional look with classic scotia beading. This combines function and form to result in a traditional window design that excels in performance.
