Aluminium Windows & Frames

Choosing the right windows for your home is a must, with benefits ranging from kerb appeal to security and top-of-the-line insulation.

The most informed decision you can make is the decision to switch to aluminium windows over your standard uPVC.

As the uPVC market shifts and aluminium windows continue to surge in popularity, many are noticing the benefits of aluminium double-glazed windows’ sleek design, customisable options, enhanced durability and energy efficiency. These windows also have superior noise reduction and are durable in adverse weather conditions.

On average, aluminium windows last up to 45 years with little maintenance – that’s 15–25 years longer than uPVC windows.

Years of perfecting our aluminium window designs have allowed us to engineer incredibly slim frames, perfect for those concerned about solar control, insulation and noise reduction.

Slimline aluminium frames also help to maximise the amount of natural light in your home, bringing more of the outside in.

We are serious about introducing the benefits of high-end aluminium windows to British homes, which is why we engineer all of our windows right here in the UK.
