SOPRATHERM TB4000 is a high-performance PIR insulation board designed for building projects where effective thermal insulation is required within a limited thickness. Formerly known as Celotex TB4000, this rigid polyisocyanurate insulation features low-emissivity aluminium-composite foil facings on both sides and a thermal conductivity of 0.022 W/mK.

Available in thicknesses from 20mm to 40mm, SOPRATHERM TB4000 PIR insulation boards provide a space-efficient solution for improving thermal performance where thicker insulation may not be practical. The rigid boards are suitable for specified building applications and can help reduce heat transfer through the building fabric.

Applications of SOPRATHERM TB4000 Insulation

SOPRATHERM TB4000 PIR boards can be used in compatible pitched roof insulation, internal drylining and floor insulation systems, subject to the design requirements of the construction. Their slim profile makes them useful for refurbishment, renovation and new-build projects where maintaining available space is important.

When choosing thin PIR insulation boards, consider the required thermal resistance, available installation depth and intended application. Always consult the manufacturer's technical datasheet and installation guidance to confirm suitability and ensure the complete construction meets relevant UK Building Regulations.
