Casement Windows

Casement windows in upvc

Casement windows are perfect for homeowners who want the thermal benefits of modern glazing technology with the beautiful aesthetics of traditional windows. The casement window is a versatile traditional style suited to a range of different properties: from period to modern.

A rated casement windows from Phoenix

All of our casement windows are A rated. This means that they have passed rigorous thermal efficiency testing to prove that they are excellent thermal insulators. A good, energy efficient window can save you as much as 20% on the cost of your heating bills.

Available in uPVC and aluminium

Our casement windows are also available in a range of materials. Aluminium casement windows offer increased thermal performance and easy maintenance, often lasting up to 60 years when well maintained. uPVC casements are likewise just as easy to maintain and are a great value alternative with good all-round performance.

Repair service

At Phoenix we also offer a casement window repair service. If you’d like to replace a particular part of a casement window, or to improve its thermal performance without having to completely replace it, Phoenix can help.
