140mm Thermaclass Cavity Wall 21 – Sopratherm Thermaclass (1190mm x 450mm x 140mm) – 2.14m2

Soprema Thermaclass 140mm

Soprema Thermaclass 140mm Cavity Wall 21 is specifically designed for full fill masonry cavity wall applications. They consist of a PIR core, which features a low emissivity foil facing. This helps to provide improve thermal performance in sealed cavity air spaces. These Soprema 140mm cavity wall boards are manufactured by Soprema, who are a leading force in the construction industry. The Soprema Thermaclass Cavity Wall 21 board is made using a blowing ageny, which is CFC/HCFC free and has zero Ozone Depletion Potential (ODP) with a low Global Warming Potential (GWP). The thickness of this board is 140mm with dimensions of 1190mm by 450mm (1205mm by 465mm including tongue).

The 21 in ‘Thermaclass Cavity Wall 21’ refers to the thermal conductivity rating, which is 0.021W/mK. The lower the thermal conductivity, the better the thermal performance.
