Enhance your cavity wall thermal efficiency with this premium-performance Kingspan Kooltherm 75mm, measuring 1200 mm × 450 mm and covering approximately 3.24 m² per pack. Designed for partial-fill cavity wall systems, this board features a rigid thermoset phenolic core and low-emissivity foil facings on both sides, delivering outstanding thermal performance with a thermal conductivity of just ~0.019 W/m·K.
The reduced thickness means you can achieve high insulation value even in constrained cavity widths, helping maintain internal floor space and ensuring a residual cavity for ventilation and moisture drainage. The board’s dimensions match standard masonry tie spacing, promoting rapid installation with minimal off-cuts.
Durability is built-in: the phenolic core is fibre-free and dimensionally stable over time, and the foil facings help resist air infiltration and moisture ingress. The product is engineered for use in standard cavity wall builds, new work or refurbishment, and supports compliance with current building regulation U-value requirements.
