Marmox Thermoblock is an insulation block designed to reduce thermal bridging at the base of the Masonry or Timber frame wall. When used in conjunction with low conductive building blocks like aircrete blocks, the heat loss at the wall floor junction can be eliminated completely. 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.
- Thermal Conductivity = 0.047W/mK
- Mean Compressive Strength = 9N/mm2 – can be used under most load-bearing walls
- Characteristic shear strength is 0.18N/mm2
The latest UK building regulations requires “continuous insulation over the whole building envelope.” Previously, insulation could not be placed under walls because it would compress but now using just one layer of Marmox Thermoblock allows the insulation to be completely gap free without any thermal bridge or heat loss.
