Description
The 42mm Structural Insulated Sandwich Panel (SIP) with PIR and Plywood is a high-performance insulated construction board designed to deliver superior thermal efficiency, structural strength, and durability. Combining a rigid polyisocyanurate (PIR) insulation core with 6mm WBP plywood facings , this panel provides an effective solution for energy-efficient building projects including roofs, walls, floors, and general construction applications.
With an excellent R-value of 1.36m²K/W and a low thermal conductivity of 0.022 W/mK , the panel helps reduce heat transfer and improve overall building performance. The foil-faced PIR core provides an integrated vapour control layer , helping to minimise moisture movement and maintain a comfortable internal environment.
Designed with a square-edge profile , the 42mm SIP panel offers straightforward installation using the butt joint technique. Its strong yet lightweight construction makes it a practical choice for builders, contractors, and construction professionals requiring reliable insulation with structural performance.
