The 43mm SIPs EPS and OSB Structural Insulated Sandwich Panel is a cost-effective and energy-efficient construction board designed to provide reliable thermal insulation, structural support, and durability for a wide range of building applications. Manufactured with a closed-cell EPS (expanded polystyrene) insulation core combined with strong 9mm oriented strand board (OSB) facings, this panel offers an effective solution for modern construction projects.

Featuring an R-value of 0.68m²K/W and thermal conductivity values of 0.037 W/mK for the EPS core and 0.13 W/mK for the OSB facings, the panel provides dependable insulation performance while maintaining structural strength. The EPS core offers lightweight insulation properties, making the panel easier to handle and install compared to traditional construction methods.

Designed with a square-edge profile, the panel allows accurate installation using the butt joint technique. Suitable for roofs, walls, floors, and general construction applications, this EPS and OSB SIP panel provides a strong, energy-efficient, and economical building solution manufactured by Custom made®.
