77.5mm Recticel Eurothane PL PIR Insulated Plasterboard

This 77.5mm Recticel Insulated Plasterboard combines rigid polyisocyanurate foam with factory-bonded plasterboard, engineered for both mechanical and dot-and-dab installation methods. Precision-controlled dimensions minimise thermal bridging whilst maintaining consistent performance across applications.

Ideal for internal wall insulation and pitched roof projects, this integrated insulation board and plasterboard solution delivers thermal control and vapour management in a single product.

Key benefits

1. Excellent thermal performance: λ = 0.022 W/mK
2. Three-in-one system: insulation, vapour control layer and plasterboard
3. Flexible installation options with multiple fixing methods

Performance and installation

Recticel's 77.5mm solution delivers superior thermal efficiency whilst maintaining ease of installation. The lightweight construction simplifies handling and cutting, allowing rapid site deployment without compromising performance. Thinner overall wall or roof build-ups preserve valuable internal space whilst achieving robust thermal control and maintaining stable indoor temperatures.

The integrated plasterboard facing eliminates separate finishing steps, reducing labour time and material costs. Straightforward cutting capabilities enable precise fitting to project specifications, making this product suitable for both straightforward and complex installation scenarios.
