Aluminium Windows from Ipswich to Essex with up to 40% off

If you want the ultimate modern performance and aesthetics, aluminium should be your window material of choice. Thin-framed aluminium windows look particularly stunning in modern homes, but with a range of wood effect finishes optional in the design process, they can also blend with traditional properties. The slimline frames allow more light to enter your home as well as giving you wide-ranging views of your garden. With superior sturdiness and durable frames, it’s one of the strongest materials on the market. Advanced manufacturing also makes it extremely thermally insulating, able to achieve A+ energy ratings. For a premium window material that can last over 45 years, aluminium is an ideal solution.

    What are aluminium windows?

    Aluminium frames undergo rigorous extrusion mechanisms, with the profiles being welded together to a specific shape. During this process, they are fabricated to minimise the heat transfer of cold elements with thermal break technology. That's why aluminium windows offer unparalleled security and durability. The innate strength allows for large panes of glass to be held and with the edge of the aluminium frame being as close as 50mm to the glass, you can take advantage of more views.

    Why choose aluminium windows?

    Sleek & slender sightlines

    We offer six popular profile choices; the modern Chamfered style, classic Ovolo frames, heritage, flush, bay and contemporary.

    Lightweight, thermally sound design

    Featuring a unique polyamide thermal break, our thermally broken aluminium frames achieve A+ energy ratings and low U-values with ease.

    Effective protection against corrosion

    Aluminium is a thermally insulating material, perfect for new windows

    Benefiting greatly from recent manufacturing techniques, aluminium is an exceptional insulator. Our range of aluminium windows can attain A+ energy ratings, the top grade available, and impressively low U-values. This is achieved through a number of advanced features. The metal window profiles are configured with a special polyamide thermal barrier. This effectively traps the heat inside of your home, whilst the draught-free design stops any cold spots from entering. We also incorporate Aerogel for additional energy efficiency capabilities, as well as our inventive double-glazing panes and warm edge spacer bars.

    With their thermal abilities, you could save significant amounts on your energy bills. Thanks to the window frame’s thermally conductive barriers, no matter the weather outside, your room will become warm in the winter and cooler in the summer.
