Alitherm 400 Doors

Combining outstanding value and quality, with class-leading performance and security, the new Alitherm 400 system provides a range of stylish casement windows and single and double doors.

The system is perfect for a wide variety of projects, including both new build and refurbishment, residential and light commercial applications and is proudly made in Britain by Smart. 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 the Building Regulations Approved Document L, 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. Security options include a choice of key wind, lift lever or slam lock multipoint locks.

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 hardware), to create elegant and contemporary entrance doors.
