Application

Suitable for partial and full fill cavity walls.

Description

A high-performance partial fill and full fill cavity wall insulation with improved thermal resistance.

BEWI Pro-Foil Cavity Wall board is an EPS board (grade 70 E HP) with a laminated air cushioned film and a reflective aluminium foil-facing. This provides a superior thermal resistance that lowers U-values enabling a reduction in cavity wall thickness. The board also provides a higher vapour resistance and a rainwater barrier. It can be installed below DPC and contributes to the reduction of the thermal bridge at the junction of the ground floor and the external wall. For further guidance refer to BS 5250 and Building Regulations.
