A casement window is the name we give to the typical style of UPVC window you’ll find in homes across the UK. It is hinged at the top or the side, and swings either outwards or inwards. Its sleek, simple design makes it suitable for most types of property. As well as optimising the natural light in your home, our UPVC double-glazed windows come with an A+ energy efficiency rating to help reduce your heating costs.
