MARMOX Thermoblock Load Bearing Insulation Block (Extra 100mm) - 140mm (10 p/bx) Black Celotex XR4000 PIR is aMarmox Thermoblock is a block of load bearing insulation material designed to be placed at the base of a masonry or timberframe wall to address the thermal bridge. Its thermal conductivity is 0. 05W mK which will result in a significant reduction in y values when used at wall to floor junctions. Its mean compressive strength is 9N mm2 allowing it to be used under most load bearing walls and its characteristic shear strength is 0. 18N mm2.
