Real Aluminium ensures thermal efficiency with Alitherm

Real Alitherm

Real Aluminium, a manufacturer of bi-folding doors, sliding doors, residential doors and casement windows, is offering customers ‘the perfect balance of aesthetics and function’ with the Alitherm 400 System. Manufactured to incorporate a pre-gasketed system and a quick glaze bead to optimise performance and reduce installation times, Alitherm 400 is ‘the first of its kind to be built into a thermally broken aluminium system’ they say.

“The innovative design features polyamide thermal break technology, which works by creating a thermal barrier between the cold air outside and the warm air inside,” said Real Aluminium’s representative. “By reducing thermal transmittance, this serves to enhance the overall U-value of the product.” Additionally, the system is rigorously tested to PAS 24:2022 as standard, and exceeds the requirements for both weather resistance and security performance.

Phil Walker, managing director of Real Aluminium added: “We are delighted to be able to offer Alitherm 400 doors to our customers. The doors perfectly complement the window range, offering the same stylish lines and ease of fabrication and installation.”

All Alitherm products are available in an unlimited colour choice, Real Aluminium’s representatives say, as any RAL colour on top of the four stock colour collections is available. To find out more about Real’s Alitherm 400 System and Real Aluminium’s full range of aluminium systems, visit
