This PIR cavity wall insulation board is designed for use in traditional masonry cavity wall construction, measuring 1200mm by 450mm with a thickness of 90mm. It features tongue and groove edges for secure jointing and easy installation, helping to create a continuous insulated layer within the wall build-up.
Typically used by builders and installers as part of a partial fill cavity wall system, the board assists in minimising thermal bridging at corners and junctions. Its format maintains a clear residual cavity, supporting moisture management and helping to protect against wind-driven rain ingress on site.
