Finest Aluminium Windows and Doors

Our aluminium range of quality double glazing solutions includes a selection of window and door systems designed to work together across the home. The window collection includes Alitherm 400, Alitherm 600, Alitherm Heritage and Alitherm 800. Each offers slim aluminium sightlines with different styling and performance options, allowing you to choose the most suitable system, whether you are replacing existing windows or designing windows and doors for a new extension.

For doors and larger glazed openings, the range expands to include Visofold bifolding doors, Visoglide sliding patio doors and Designer aluminium entrance doors. These systems allow you to open up garden views, create wider access to patios and terraces, or make a strong design statement at the front of the property.

Because these systems are designed as part of a wider aluminium collection, windows and doors can be specified together with consistent colours, finishes and hardware. This makes it easier to create a coordinated look across the property while selecting the individual products that best suit each room and opening.

Modern Aluminium Window Design in a Traditional House

Aluminium windows offer a unique combination of modern design and timeless versatility. While their sleek, slimline profiles and minimalist appearance make them an excellent choice for contemporary homes, they are equally well-suited to traditional and period properties.

Thanks to their customisable styles and finishes, aluminium windows can complement classic architectural features while offering durability, energy efficiency, and low maintenance.

This makes them a perfect solution if you want to blend modern performance with traditional charm.

This house perfectly embodies that traditional style house with modern aluminium windows. The flat-framed style is not unique to modern design. Crittal windows had a flat frame design over 150 years ago.

Aluminium Windows and Doors in Stowe on the Wold

These aluminium windows were installed at a beautiful home in Stow-on-the-Wold, where the homeowners wanted a clean, contemporary look without losing the connection to the surrounding countryside. The slim aluminium frames allow for larger panes of glass, which means more natural light in the room and uninterrupted views across the garden and landscape beyond.

For the homeowner, aluminium offers both practical advantages and a modern appearance that still works with their traditional furniture.

Energy efficiency is another benefit. These windows are fitted with high-performance double glazing and thermally broken aluminium frames to help keep warmth inside during colder months. The result is a comfortable living space with plenty of light while still helping to control energy use.

The anthracite style finish works well with both traditional Cotswold homes and modern interiors. It gives the property a crisp architectural feel inside and out, while the aluminium construction ensures the windows will continue to look good and perform well for many years.

These customers chose Anthracite inside and out, but could have chosen white for the inside. We think the anthracite provides a perfect frame for the view.

Based in Stratford upon Avon, Prior Products installs aluminium windows across Warwickshire including Warwick, Leamington Spa, Alcester, Evesham and the surrounding towns

Over 200 Colour Options

Aluminium gives you far more choice when it comes to colour and finish. At Prior Products, we offer a selection of popular colours available on short lead times, including White, Jet Black, Anthracite Grey and Anthracite Grey on White. These shades suit many modern homes and extensions and remain some of the most frequently chosen options.

If you are looking for something more individual, aluminium can be powder coated in over 200 colours from the RAL colour chart. This allows you to match existing features, complement brickwork or create a distinctive architectural look. Finishes are available in matt, gloss or textured coatings, depending on the style you prefer.

There are also additional specialist colour collections available with metallic, anodised and textured finishes that bring even more design flexibility.

With such a wide choice, aluminium windows and doors can be tailored to suit both contemporary and traditional homes while maintaining the durable, long lasting finish that powder coated aluminium is known for.
