Blending the old with the new

Ideal for home improvement projects which require sympathetic installation such as listed buildings and conservation areas, the Alitherm heritage range allows for no compromise when it comes to aesthetics. The range has been approved for use by many local authorities including London boroughs and CADW – the Welsh government’s historic environment service.

Using innovative polyamide thermal break technology, a barrier is created between the warm air inside and the cold air outside. This ensures that the windows and doors achieve high U values with no draughts. Utilising the exceptional strength of aluminium, these windows and doors are expertly made to the highest standard. The strength of aluminium allows it to hold more glass with slimmer sightlines to bring more light in.

A resilient yet attractive range for residential and commercial properties

Highly durable, they are tested to ensure they can withstand the harshest of storms and whatever the British weather throws at them. With no rusting, fading or deterioration, they are perfect for use even in harsh coastal areas.

Security is a priority when it comes to our products and the Alitherm Heritage range is no exception. All of our windows and doors come with multipoint locking mechanisms for peace of mind.

One of the key selling points of aluminium as a material for windows and doors is that it requires little to no maintenance. Just a simple wipe down is all that’s needed to keep it looking as good as new. Our powder coated finishes offer a wide array of colours including metallic and heritage options and heritage hardware is also available to maintain a traditional style. Slim sightlines ensure the windows and doors allow more light in and give a sophisticated appearance.

Aluminium is recyclable so at the end of its use it can be reused - a plus point for the environment and the carbon footprint of your project.
