This partial fill cavity board is a rigid PIR insulation product with tongue and groove edges, measuring 1200mm by 450mm and 75mm thick. Designed for installation in masonry cavity walls, it supports consistent insulation while maintaining a clear cavity for ventilation and moisture control.
Commonly used in both new build and refurbishment projects, the board helps reduce heat loss through external walls. The tongue and groove profile assists with straightforward jointing and fitting, while also minimising the risk of thermal bridging at board edges and corners.
