Description

Features:

Galvanized steel is used to support the heavier load on the inner leaf of the cavity wall.

Subjected to a fire test in accordance with BS EN 1363-1, at Exova Warrington Fire and achieved a one hour fire performance.

Benefits:

Up to five times more thermally efficient than a steel cavity wall lintel, Hi-Therm outperforms other lintels.

The significant reductions in thermal bridging due to the GRP component will assist in the building design process to achieve compliance with Part L and The Code for Sustainable Homes.

The use of Hi-Therm will make a significant contribution to a building's performance in respect of the Fabric Energy Efficiency Standards (FEES).

Usage:
