A load bearing thermal insulation block which eliminates the cold bridge at the wall/floor junction. Marmox Thermoblock is a block of load-bearing insulation material designed to be placed at the base of a masonry or timber–frame wall to address the thermal bridge. Its thermal conductivity is 0.047W/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. Additionally, because they are impermeable to water they can be used in damp conditions without any loss of their insulating properties. So, not only do Thermoblock thermal insulation products reduce thermal bridging, but they also create a moisture barrier.
