Casement windows are among the most efficient windows available due to the tight seal between the sash and frame. Their airtight seal aids the thermal performance of our uPVC windows, stopping the ingress of cold air and preventing damp. All our windows are made using modern technology.

Thermal Efficiency

We use the best insulating materials for our plastic windows, ensuring optimal thermal performance. Our uPVC casement windows are available with energy ratings of up to ‘A’. With energy prices soaring, our windows can insulate the home and could help reduce the homeowner’s energy bills.


Our uPVC windows have been designed to achieve the perfect balance between style, energy efficiency and security. As standard, the windows come with a multi point locking mechanism. For enhanced security, homeowners have the option to upgrade to our comprehensive PAS 24 security package.

Manufacturing Guarantee

With all casement windows manufactured here in West Yorkshire, there is a manufacturing guarantee of up to ten years as standard. While all our windows provide outstanding, long term quality, we appreciate that having a decade long guarantee on key components offers peace of mind.

How much do casement windows cost?

We offer competitive pricing on all products. It would be difficult to pinpoint an exact price, as it depends on the dimensions, style and accessories that the homeowner chooses for the project. You can use our online window designer or get in touch with our West Yorkshire team to get a price.

Will uPVC casement windows reduce the noise levels from outside?

If you are replacing your single glazed windows with new casement windows from Quickslide, the homeowner will likely see a noticeable reduction in noise pollution. With the extra layer of glass found in the double glazed unit, less sound will be able to filter in.

How long does the replacement work take?

Replacing a casement window can be a complex job and requires excellent attention to detail. It takes between one to two hours to install into a new build, and three to five hours to remove an existing window and replace it with a new one.

We have a fantastic installation guide for you to take a look at if you need more information. A double glazed uPVC window replacement is definitely worth the work, as it can offer much more energy efficiency and security.

What is a casement window?

Casement windows are recognisable by sashes that are attached to their frame via one or more hinges.

At Quickslide, we have a range of popular uPVC double glazed windows beyond our casement range. The windows for sale via our website include sash windows, French, flush, and more.

I have used Quickslide a few times for their sliding sash windows. The service from the staff is quick and professional, they are always there to give advice and offer help with any query. The quality of the windows is excellent. They are a pleasure to install and have not had any problems with them since. They are easy to operate and keep the rooms warm and draught free in the winter months. All in all, I would not hesitate to recommend Quickslide and their products, one of, if not the best company I have dealt with.

Phil Wooller

Been using Quickslide for a few years now. Really happy with their product and customer service. Staff are always friendly and willing to help. An all round really nice company to deal with.

Swift Windows

Our customers, particularly in the traditional buildings around York, mainly request the 'Legacy' Sliding Sash windows. These windows look fabulous; so authentic that many people are shocked to discover they are not made of wood. The windows are a great advert and more often than not, having installed Quickslide 'Legacy' windows in a property, the neighbours will approach us for quotes for their own houses.

Juliet Waters

Our experience from first encounter at the Quickslide Sales office in Brighouse to the completion of 14 fantastic new sash windows, was absolutely first class. The company was a pleasure to work with throughout the process. Knowledgeable and extremely pleasant and capable staff at all points along the way.

Kevin Galloway

We ordered over 30 mainly sliding sash windows in 2 batches for a project. The quality of the windows is excellent and great value for money. The lead times for both orders were accurate. The communication prior to each delivery and from their own drivers were faultless.
