SOPRATHERM GA4000 is a high-performance PIR insulation board designed to improve the thermal efficiency of buildings. Formerly known as Celotex GA4000, this rigid polyisocyanurate insulation features low-emissivity aluminium-composite foil facings on both sides and a declared thermal conductivity of 0.022 W/mK.

Available in thicknesses from 50mm to 100mm, SOPRATHERM GA4000 insulation boards offer a range of thermal resistance values to suit different building specifications. Each board measures 2400mm × 1200mm and has straight edges for consistent installation within compatible insulation systems.

Applications of SOPRATHERM GA4000

SOPRATHERM GA4000 PIR insulation is suitable for specified pitched roof insulation, internal drylining and floor insulation applications. It can be used in appropriate new-build and refurbishment projects where effective thermal insulation is required without adding unnecessary thickness to the construction.

When choosing PIR insulation boards, consider the required thickness, thermal resistance, available space and intended application. Always follow the manufacturer's technical datasheet and installation guidance to ensure the insulation system meets the relevant UK Building Regulations and project requirements.
