Xtratherm CavityTherm wall insulation board is a high performance board of enhanced PIR. It is the best solution when designers demand additional thermal insulation in the masonry walls. Xtratherm Thin-R achieves high standards of insulation and at the same time maintains residual cavity to prevent moisture penetration, without any considerable increase in cavity and of the overall wall thickness.
The board includes specifically designed rebated edge detailing on all four edges to allow the system to tightly interlock when installed. The jointing of the insulation layer ensures continuity and excellent results in thermal binding and bridging.
