HEAT creates sustainable construction systems through innovation in the material’s microstructure and the reuse of waste materials. One of our patented products is HEAT concrete, a new material for exterior walls of sustainable houses with 10x more thermal insulating and 3x lighter than conventional concrete. We also developed a HARD version 2x lighter for precast elements of higher strength. The core of our concretes is HEAT aggregates: novel lightweight aggregates made from recycled glass with 15x thermal insulating and 5x lighter than normal weight aggregates.
