Flush Casement Window Materials

With strength like no other material and a lifespan measured in decades rather than years, aluminium has become the perfect choice for homeowners. One of the main benefits of aluminium is its low and straightforward maintenance, as well as the whole host of configurations available. Aluminium windows can be fixed, top hung or side hung with ease.

Flush Casement Window Designs

If a project requires elements of heritage without compromising on performance, then our aluminium flush casement windows are the obvious choice. When closed, the window sashes sit flush into the frame. This design is considered in-keeping with traditional aesthetic as it imitates the construction of original timber or metal windows.

Product Options

Our Colour Options

Our aluminium flush casement windows come in three stock colours, with the option of other bespoke finishes on request. Consistently fade proof and long lasting, we can also apply a different finish inside and out. Dual colour windows are ideal when internal spaces are very different to a building’s façade.

The flush casement window has not only been engineered to demonstrate a unique design, but also a top of the class weather performance. Advanced seals help keep rain, wind and snow at bay, while also helping to keep energy bills low and the home at the desired temperature all year round.

Thermal Efficiency

It’s the well thought through composition of the aluminium profile found beneath the external flush design that enables this window to achieve an outstanding U-value of as low as 1.5 W/m2K. The aluminium flush casement windows enable homeowners to get a solution that’s beautiful and performs inside out.


Our aluminium windows have been security tested to PAS 24, and our flush fitting system is no exclusion to that. Also, utilising a multi point locking mechanism and key locking handle, our aluminium flush casement windows can provide complete peace of mind for the homeowner.

Manufacturing Guarantee

Protecting customer investments, we provide a manufacturing guarantee of up to ten years with our aluminium flush casement windows. When you supply through Quickslide, you can market this warranty to prospective customers, turning enquiries into window installations.

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.
