Modern Aluminium Windows

When looking to get the best possible performance from your Newbury home, upgrading to aluminium windows is a must. Delivering complete weatherproofing, unrivalled thermal efficiency and a superb lifespan, aluminium windows are one of the most modern and innovative renovations options on the market today. We also recommend you make the upgrade wherever possible.

Aluminium windows also offer superb visual appeal to partner these unmatched performance levels. With aluminium being a naturally more durable material, the window’s sightlines can be made slimmer without compromising on structural rigidity. Doing this allows the design of these windows to deliver sleek and contemporary aesthetics in any scenario.

However, our aluminium windows can be designed to suit both modern and traditional properties here in the Berkshire area. The framework can be finished both internally and externally thanks to our dual colour option. We have a wide array of different options and something for every taste. You can then complement the colour by choosing from a range of authentic accessories and handles.

Smart are our designated aluminium windows supplier. They provide us with both their Alitherm and their Heritage profiles for our installations, providing us with more choice to offer you. Each profile delivers the benefits you’d expect from aluminium windows. You know with Smart grade profiles that you’ll be getting the very best. We don’t compromise here at Castle Windows.

Thermally Retentive

Aluminium is a fantastic natural insulator. It can retain significantly more heat than uPVC or timber before the addition of thermal enhancements. With this, you can expect U-values as low as just 1.5W/m2K when you make the upgrade to aluminium windows.

The profile we use from Smart has been thermally broken, effectively adding internal chambers that prevent the ingress of cold air. Within the profile is modern double or triple glazing of varying thicknesses, which allows these windows to achieve an ‘A’ Window Energy Rating.

Reliable Weatherproofing

Our aluminium windows offer a reassuring standard of weatherproofing. Aluminium’s long lasting properties include the ability never to rot, bow or distort, as well the fact it will never become permeable to water. This leads to excellent weather protection.

Your home will never be bothered by problems including damp spots, mould or leaking. Internal systems ensure all rainwater is filtered away, preventing misted glazing. You have complete peace of mind, even in the most extreme conditions.

Low Maintenance

Aluminium is a naturally long lasting material. Despite this, it requires very little upkeep to look it’s best, with our aluminium windows only requiring occasional, specific maintenance. The coloured foil will never fade thanks to marine grade powder coating.

You’ll need to pay particular attention to the window’s moving components, such as the handles, locks and hinges. They’ll need to be kept free of excess dust, as this can cause any of them to jar or become sticky. Little else is required beyond that, however.
