The 106mm Unilin XO/STP XtroLiner Soffit+ PIR Insulation Board is a high-performance structural ceiling insulation solution designed to deliver exceptional thermal efficiency, fire performance, and durability in commercial and residential buildings. Manufactured from polyisocyanurate (PIR) rigid foam insulation, this soffit board provides outstanding insulation performance for structural ceiling applications.

With a low thermal conductivity of 0.021 W/mK and an excellent R-value of 4.75m²K/W, the XtroLiner Soffit+ offers superior thermal resistance to help improve building energy efficiency. The board features a durable 6mm impact-resistant building panel finish, providing a suitable surface for decorative finishes where required. The foil-faced design enhances vapour resistance and contributes to long-term insulation performance.

With a Euroclass B, s1-d0 fire classification and BBA certification (No. 12/4956), this insulation board provides an effective thermal and fire performance solution for structural ceilings. Suitable for installation using timber battens or direct fixing to concrete, the 106mm XtroLiner Soffit+ is ideal for high-performance ceiling insulation systems.
