What is a casement window?

A casement window is traditionally one with a hinged sash that opens out like a door. However there are other options for your casement windows and you can choose to instead opt for side hung, top hung or even bottom hung. If you’re feeling unsure at which style to choose then our friendly team have more than 10 years of experience fitting windows in Surrey, Berkshire and Hampshire and will be able to give you all the information you need to make an informed choice about which style is right for you.

Our uPVC casement windows are available in a range of colours and finishes. If you are looking for something to enhance your traditional character property then our wood effect finishes could be ideal – choose from rosewood, mahogany, Irish oak or golden oak. For a more contemporary look, white, slate grey, dark grey or black could be a stylish choice. Or add some quaint English style to your home with our popular cream or chartwell shades.
