Alitherm 400 Contemporary Doors

Alitherm 400’s design incorporates Smart’s innovative polyamide thermal break technology, which creates a barrier between the cold air outside and warm air inside, significantly reducing thermal transmittance and enhancing the system’s overall U-value. The system is also fully compliant with changes to Document L of the Building Regulations, is rigorously tested to PAS 24:2016 as standard and exceeds the requirements for weather resistance and security performance.

Alitherm 400 doors perfectly complement the window range, with the same stylish lines and providing the same ease of fabrication and installation. Available as open-in or open-out, single or double doors, the system provides excellent weather and thermal performance, as well as the security assurance provided by PAS 24:2016 accreditation.

Suitable for both residential and commercial applications, Alitherm 400 can also be combined with Smart’s Designer Door Panels and the company’s range of standard door furniture (including colour matched lever handles, and the Quantum range of stainless steel)
