Specification
Description
140mm Thermaclass Cavity Wall 21 is a rigid polyisocyanurate (PIR) insulation solution from Celotex for masonry full fill cavity wall applications. Featuring a tongue and groove edge profile, Thermaclass Cavity Wall 21 has an excellent thermal performance of 0.021 W/m.K (lambda 21) which can help to achieve lower U-values without increasing the overall wall thickness. For wall constructions featuring a 10mm residual cavity, the low-emissivity foil facing increases the thermal performance in sealed cavity air spaces, improving the achievable U-value. Thermaclass Cavity Wall 21 has been assessed by the British Board of Agrément (BBA) as fit for use in defined full fill cavity wall applications if installed, used and maintained as set out in the certificate.
