Alitherm Heritage Windows

Our aluminium heritage windows replicate the slim, elegant lines of traditional steel windows. This makes them perfect for conservation areas, listed buildings, and period property renovations where maintaining the original look is essential.

At the same time, they’re made from durable aluminium, which won’t rust or warp. As a result, clients will be able to get a traditional look without much maintenance.

Thanks to aluminium’s natural strength,  our heritage windows support large panes of glass in slim frames. This brings in more light and results in a sleek, contemporary finish. Perfect for both residential and commercial applications where visual impact matters. 

The strong frames are lightweight and easy to install.  It helps speed up project timelines and reduces the strain on structural openings, which is perfect for older buildings.

Modern aluminium heritage windows come with a built-in thermal break, which is an insulated barrier between the inner and outer frame, which helps prevent heat loss. This means better insulation and lower energy bills for your customers. 

For trade developers, this ensures your projects meet current energy standards without affecting its visual aesthetics.

Aluminium Heritage windows are designed to meet planning requirements in sensitive areas, making them an approved option for listed or protected buildings. Their authentic design quickens the approval process with local authorities.

This makes it easier for trade professionals across Leicestershire and Derby to keep projects moving without any costly delays.

Heritage aluminium windows are ideal for listed buildings and properties in conservation areas, offering the traditional steel-look aesthetic required by planning authorities.

Unlike traditional steel or timber alternatives, aluminium requires minimal upkeep and resists corrosion over time.
