Alitherm 400 Windows
The Alitherm 400 system offers outstanding quality, performance and value via a range of stylish aluminium windows. As the first thermally broken aluminium system to feature an extruded glazing gasket, it provides enhanced performance and reduced installation time. Its innovative design incorporates polyamide thermal break technology that significantly reduces thermal transmittance, enhancing the systems overall ‘U’ value. Available in stock colours, Alitherm 400’s new Quick-Glaze Bead is simply tapped in on site with the gasket already in place, eliminating the need for wedge gaskets on internally beaded windows. Making for a faster, simpler and more cost-effective glazing process.
Design Options
Alitherm 400 casement windows are currently available in two options. The popular Alitherm 400i range is an internally beaded system with dummy sashes which can achieve PAS 24 security standards. Alternatively, the externally glazed Alitherm 400x range can be upgraded to PAS 24 security standards by introducing glass security clips.
NEW! Alitherm 400 Flush Sash window, tilt and turn window and Heritage windows and doors are also available!
Quick Glaze Knock-In Bead
Quick Glaze Knock-In Bead is standard on internally glazed windows with 28mm double glazing, ensuring a faster, simpler and more cost-effective glazing process.
