Casement Windows
The most popular style window for UK homeowners, our high-quality casement windows offer both internal and external benefits for your home. Whether you live in a modern new build property, or an older, more traditional home; our casement windows are sure to complement your home’s design.
What is a casement window?
Available in both uPVC and aluminium frames, casement windows are capable of effortlessly enhancing both heritage and new build properties alike. Their low maintenance qualities also appeal to the busy lifestyles of the 21st-century homeowner.
A casement window is attached to the frame by one or more hinges and a mechanism that cranks the window outwards, away from the home. The casement window has many different configurations; the openers can be top hung, side hung, or even fixed. Where the window is hung describes where the window sits on the hinges. The most popular casement is the side hung, hinged at the side for easy opening.

Peace of mind with our aftercare package
Here at Puredoubleglazing and Doors, we pride ourselves on being on hand for our customers from start to finish, however, we don’t believe the journey is over once the installation is complete.
We offer what we call our aftercare package. We will make a call 4 weeks after the installation completion, and should there be any issues whatsoever, we will send out our aftercare team who are on hand to make adjustments, carry out repairs, glass replacements, and more.
Our aftercare package does not carry a call-out charge and nothing is too much trouble. Our team is passionate about completing each job to the highest standard.
