T2 - Thermalwall Building Technology - Thermal Mass Effect - Thermal Wall T2, Thermalwall Building Technology is an integrated approach to constructing insulated concrete buildings. The objective is applying the insulation layer to the exterior of the structure. Thermal mass effect is simply the ability of concrete mass to absorb and store heat. Thermal mass walls have a much higher R value. Thermalwall.com~Site InfoWhoisTrace RouteRBL Check
