Despite their traditional window design, the Alitherm Heritage system boasts of a performance that is impressive even by modern standards. Maximum U-values of 1.5 W/m²k far exceed modern standards for thermal performance, making them ideal for use in applications requiring energy-efficient windows.
A PAS24:2016 accredited system, we can fit them with a selection of high-quality hardware from Yale for enhanced security performance too. They’re also BS6375-1:2009 accredited, proof of their ability to keep interiors wind and weather-free.
