37.5mm SOPRATHERM PL4025 Insulated Plasterboard

37.5mm SOPRATHERM PL4000 PIR Insulated Plasterboard (previously Celotex PL4000) is a high-performance thermal laminate insulation board designed for internal wall insulation and pitched roof applications. The board features a 25mm rigid polyisocyanurate (PIR) insulation core with a low thermal conductivity of 0.022 W/mK, bonded to a 12.5mm tapered edge plasterboard to provide both insulation and a ready-to-finish internal surface.

This 37.5mm Soprema PIR insulated plasterboard is widely used for dry lining walls, ceilings and pitched roofs, helping to improve the thermal efficiency of homes and commercial buildings while reducing heat loss. The combination of PIR insulation and plasterboard allows for faster installation compared to installing insulation and plasterboard separately.

37.5mm SOPRATHERM PL4025 boards are available in overall thicknesses ranging from 37.5mm to 77.5mm, making them suitable for a variety of insulation requirements. The product is BBA certified for specific applications, including internal wall dry lining and pitched roof ceiling insulation, ensuring reliable performance and compliance with UK building standards.
