Future proof your home with design excellence

Aluminium continues to grow as the material of choice for windows and doors throughout the UK, and it’s easy to see why!

The sleek, stylish profile of aluminium clearly sets it apart from the competition. Slimmer yet stronger frames support larger spans of glazing. This means homeowners can enjoy expansive, picture-perfect views of their outside space whilst enjoying bright, airy interiors.

But aluminium’s attractive finish is not its only asset. By its very nature, aluminium is strong, secure, durable and thermally efficient – all qualities that every homeowner should expect as standardSAS aluminium is also fully recyclable, helping you reduce your carbon footprint.

For over 30 years, Senior Architectural Systems has been behind aluminium windows and doors of the highest calibre. We are proud to install their products in homes throughout Cheshire, with the pressure-free and dedicated service our customers have come to expect.

You want your home improvement project to be very everything you’d envisioned – and so do we.
