The 58mm SIPs EPS and OSB Insulated Sandwich Panel is a cost-effective, energy-efficient construction board designed to provide reliable thermal insulation, structural support, and durability for a variety 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 a practical solution for modern construction projects.

With an R-value of 1.08m²K/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 delivers effective insulation performance while maintaining structural stability. The lightweight EPS core improves handling efficiency, while the OSB facings provide a durable and robust construction surface.

Featuring 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®.
