Thermoblock®, an innovative steel-reinforced insulated concrete form (ICF), is one of the most energy-efficient building systems available today. The ThermoBlock system utilizes cast-in-place post and beam concrete construction, giving the customer a 300% stronger building compared to conventional construction. Resembling large-scale Lego® blocks, the system uses a combination of interlocking, lightweight, stackable polyurethane blocks which can be fabricated on-site, along with concrete, steel reinforcing rebar, and a patented internal stud. Because the system utilizes high density closed cell polyurethane foam, it offers exceptional insulation value (R 38); is resistant to insects; does not allow moisture transmission, eliminating mold and mildew; and is very quiet with excellent sound transmission characteristics. ThermoBlock provides a more comfortable and secure living environment.
