Description
The 57mm Structural Insulated Sandwich Panel (SIP) with PIR and Plywood is a high-performance insulated construction board engineered to provide superior thermal efficiency, structural strength, and durability for modern building projects. Manufactured with a rigid polyisocyanurate (PIR) insulation core combined with 6mm WBP plywood facings , this panel delivers an excellent balance of insulation performance and mechanical stability.
With an impressive R-value of 2.05m²K/W and a low thermal conductivity of 0.022 W/mK , the panel helps minimise heat loss and improve energy efficiency in residential, commercial, and industrial applications. The foil-faced PIR core provides an integrated vapour control layer , helping reduce moisture transmission and support long-term building protection.
The square-edge profile enables straightforward installation using the butt joint technique, while the lightweight construction allows easier handling and fitting on site. Suitable for roofs, walls, floors, and general construction applications , this 57mm SIP panel is a reliable choice for projects requiring high insulation performance and dependable structural support.
