The ICF-Therm system consists of two opposing insulation panels moulded from high density expanded polystyrene, the panels are spaced apart using high strength polypropylene webs to form straight and 90° corner ICF blocks. To enhance the systems thermal performance, header and cavity closer panels are inserted around window and door openings. During ICF wall assembly steel reinforcement is fixed in specified locations and the wall temporarily braced. Readymix concrete is then placed into the ICF-Therm wall to deliver a super strong and air-tight insulated structure. The ICF-Therm system is available in three different U-value options each with either a 150mm or 200mm concrete core thickness.
