126mm XO/STP Unilin XtroLiner Soffit Plus Board (pack of 8)

The 126mm Unilin XO/STP XtroLiner Soffit+ PIR Insulation Board is a high-performance structural ceiling insulation solution designed to provide outstanding thermal efficiency, fire performance, and durability for commercial and residential buildings. Manufactured from polyisocyanurate (PIR) rigid foam insulation, this soffit board delivers excellent insulation performance for structural ceiling applications where high thermal resistance is required. With a low thermal conductivity of 0.021 W/mK and an impressive R-value of 5.70m²K/W, the XtroLiner Soffit+ provides superior thermal protection while maintaining an efficient board thickness. The board features a durable 6mm impact-resistant building panel finish, allowing decorative finishes to be applied where required. The foil-faced surface enhances vapour resistance and supports long-term insulation performance. Providing a Euroclass B, s1-d0 fire classification and BBA certification (No. 12/4956), this insulation board offers an effective thermal and fire performance solution for structural ceiling systems. Suitable for installation using timber battens or direct fixing to concrete, the 126mm XtroLiner Soffit+ is an ideal choice for high-performance ceiling insulation projects.
