UPVC Casement Windows

Casement windows are the most popular window style in the UK and are mostly preferred by people looking for UPVC windows in Horsham. Our UPVC casement windows are available with side-opening, outward or top-hung vents; we can also install them as bow or bay windows, and even add fixed lights to create stylish combination frames. Southern Window Company’s UPVC windows can be tailored to your exact requirements – we supply custom windows that suit you!

Our excellent range of new and replacement UPVC casement windows will offer you the perfect solution in terms of the lowest possible levels of maintenance, ranging from the most popular and effective high gloss smooth white UPVC through to textured woodgrain foils and colours, such that you can still match your home to the aesthetic of the previous windows and the surrounding neighbourhood.

All of our UPVC casement windows are also internally glazed and feature multi-point locking which in combination makes it also impregnable to attack from intruders.

Our UPVC casement windows also offer you the added benefits of extreme energy efficiency. The glass that is used to construct the double glazed sealed unit has a thermal coating which when combined with argon gas filling and modern warm edge spacer bar technologies, offers you an ‘A’ rated thermal performance.
