Product Information
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 24:201 as standard and exceeds the requirements for weather resistance and security performance.
Available with a flush or chamfered profile, the slim lines of Alitherm 400 provide excellent weather and thermal performance, as well as the security assurance provided by PAS24 accreditation. While the flush, flat face option is suitable for off-set, face-mounted espagnolette locks, the chamfered design features a eurogroove, to enable in-line espagnolette locking mechanisms to be used.

What are Alitherm 400 Contemporary Windows made from?
Alitherm 400 windows are crafted from high-quality thermally broken aluminium. This material offers excellent strength, durability, and slim sight lines, while maintaining top energy efficiency through an internal thermal break that reduces heat loss.
Can Alitherm 400 windows be used in both modern and traditional homes?
Yes. These windows are designed with versatility in mind. Their clean, slim profiles suit contemporary architecture, while the flush casement and chamfered options also complement more traditional or heritage-style homes.
How do I maintain and clean aluminium windows like the Alitherm 400?
Aluminium windows are low-maintenance. Regular cleaning with warm soapy water and a soft cloth is usually enough. Unlike timber, they won’t warp, rot, or need repainting, just an occasional check of seals and moving parts to ensure optimal performance.
