All Alitherm 400 profiles utilise Smart’s innovative polyamide thermal break technology which creates a barrier between the cold air outside and the warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U Value of a product.
Flush Sash or Stepped Sash is available within this versatile system:
- Fully compliant with changes to Document L of the building Regulations in June 2022
- Smart Quick-Glaze Beads featuring integrated gasket and ‘tap-in’ design for easier fabrication and faster installation
- PAS 24:2016 Approved – enhanced security for aluminium windows and doors
- Unrivalled Choice of Colour
- Suitable for Residential and Light Commercial Properties
The Alitherm 400 window is the first thermally broken aluminium system to feature Smart’s pioneering coextruded glazing gasket. This means the beads are supplied with the glazing gasket post-extruded into the profile. This enables the Quick-Glaze beads to be simply tapped in on site, significantly reducing fabrication and installation time.
