The InSpire wall solar air heating system is used to pre-heat outside air before it enters the building to provide fresh-air changes and natural humidification, as well as opportunities to reduce energy consumption. The panel is mounted at a specified distance of several inches from the outer wall of the building. InSpire features proprietary engineered perforations which allow outside air to be transpired (drawn through the panel) into the wall cavity via ventilation fans. InSpire panels are coated with a fluoropolymer (PVDF) coating system in colors which allow absorption of the sun’s energy to pre-heat surface and cavity air. The solar generated heat transpires into the wall cavity and is drawn into the building’s interior through conventional ductwork.
