About Aluminium Casement Windows

Aluminium casement windows are the most popular window choice for UK homeowners and building developers. Available with a range of customisable options, casement windows are the perfect choice for both traditional and contemporary residential designs.

Our aluminium casement windows are extremely versatile in terms of design aesthetics. They can be specified with a Bay, Chamfered, Heritage, Ovolo, or contemporary appearance to suit almost any building aesthetic. They can accommodate a frame depth of 58mm or 70mm and can be glazed with 24mm -40mm glazing either internally or externally.

Thermal Performance

The Aluk Optio 58bw aluminium casement windows that we provide are designed from the ground up with thermal efficiency in mind. They can be internally or externally glazed to suit your specific needs and can come with 24mm or 40mm glazing for optimal energy insulation. 

With U-values as low as 1.4 and with an ‘A’ energy rating, our aluminium casement windows can keep homeowners warm and comfortable throughout the year. No matter what type of configuration you’re after, from top hung, bottom hung, side hung and fixed light to multi-light and French casement, our aluminium casement windows provide some of the best insulation on the market.

The aluminium profile contains a series of polyamide thermal breaks to enhance the thermal performance further, providing incredible durability and insulation without compromising on a sleek and functional window design.


Safe & Secure

All our aluminium casement windows are certified under the Secured by Design scheme and rated A by Green guide. They have undergone rigorous and extensive safety inspections and tests to meet PAS 24 requirements so homeowners can have total peace of mind when you install our safe and secure aluminium casement windows.

Aluminium is a lightweight yet robust material that is capable of withstanding almost any weather conditions within the UK. Unlike other materials, they can easily resist warping, cracking, or swelling from absorbing moisture or intense heat. The PAS 24 certification showcases our aluminium casement windows’ ability to resist modern intrusion techniques so that homeowners can remain safe from the elements and unwanted guests.

We also provide the ability to choose between project in our project out options to suit your home improvement project needs. Our aluminium casement windows are also available for Lifetime Homes (LFT).

Low Maintenance

These aluminium casement windows only require occasional cleaning with a fresh wet cloth or sponge to keep them looking and performing at their best. The range of single, dual colour, and anodised finishes we offer are designed to last for years without fading from harsh weather conditions. You’ll never need to sand or varnish these slim and sleek profiles.

Adverse weather conditions aren’t to be feared, as the integrated deep head profiles allow easy trickle ventilation. Homeowners can keep out cold draughts and leaks while continuing to get excellent air ventilation throughout their homes.

Choose between 58mm or 70mm frame depth to best suit your needs, and pick the aesthetic that best matches your project from Bay, Chamfered, heritage, Ovolo, and Contemporary. No matter your choice, each one is constructed of high quality aluminium that is capable of lasting almost three times as long as any other type of window material.
