    What are aluminium windows?

    Aluminium window frames are made from extruded profiles welded together to from the required shape. They are fabricated to minimise heat transfer, offering good energy performance in addition to their security and durability. The strength of aluminium makes it possible for large panes of glass to be held in narrow frames, increasing available light.

    What aluminium windows can do

    Slimline design

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

    Effective protection against corrosion

    Finished in an anti-fade, anti-corrosion coating, our aluminium windows are exceptionally strong and weather-resistant.

    Lightweight, energy efficient design

    Featuring a unique polyamide thermal break, our aluminium windows achieve energy A+ ratings and low U-values.

    Exceptional home security is locked in

    Able to last up to 45 years, the majority of our aluminium windows are certified by the Police Preferred Specification Secured by Design and tested to PAS 24 as standard.

    10 years’ product guarantees

    All new windows carry a standard guarantee for 10 years on fit, function and finish.

    Aluminium is a thermally insulating material, perfect for new windows

    Highly recyclable as a material, aluminium helps to lower your home’s environmental impact and with efficient thermal insulation, your heating bills will be lower too.

    A polyamide break—a rigidly fitted section in the window frame that prevents draughts—is a superior element of our aluminium windows that improves thermal efficiency. Alongside our A+ rated Comfort Glass, heat transfer is dramatically reduced so that your home is always the optimum temperature.

    Aluminium is a strong material which makes it the perfect choice for replacement windows. Its inherent durability will keep your home secure and protected from intrusion as well as bad weather. Aluminium window’s durability makes them perfect for homes in harsher environments such as coastal areas as they can withstand constant harsh winds and conditions.

    Excellent noise reduction with modern double-glazed aluminium windows

    New aluminium windows improve on noise insulation over older units or timber windows. Better quality glazing panes and more density in window frame designs keep exterior noises outside—ideal if you work from home. Whether you opt for double glazing or comfort glass in your new aluminium windows, noise reduction is improved by dense glass panes that are tightly bonded into the aluminium frames.
