Due to their energy efficiency, long lasting durability and design flexibility, precast/prestressed Insulated wall systems have gained allot of popularity. Thermomass was one of the first insulation and pin systems available for creating precast sandwich panels. From the day the Thermomass inventor showed up at our plant, pulling a prototype from his trunk, we saw the merit of encasing the insulation between two layers of concrete that protected it from damage or moisture infiltration. After offering the system to some innovation-minded customers, we found it exceeded their expectations and ours. From there we used it in other types of buildings and other parts of the country and it continues to be a building system of choice to our customers today.
