AIRFLOOR™ is a hybrid radiant/forced air system that leverages the advantages of a forced air system; rapid response times, and provides both heating and cooling yet delivers the thermal comfort and efficiency advantages of a radiant system. In lieu of using heated water lines like a traditional radiant floor system, AIRFLOOR™ uses conditioned air from conventional mechanical equipment.
Simple sheet metal stamped bowls resembling mini-igloos, 12 inches square with openings on each side are hooked together over the entire subfloor of a home, and then covered with a thin layer of light weight self-leveling concrete. This creates a hollow concrete floor providing both radiant and forced air heating and cooling, with the ability to locate registers anywhere in the floor without conflict or coordination. Although the concrete floor is pressurized with air, the entire floor acts like a giant duct, so air is delivered to the registers at a low velocity. The noise of blowing air is almost eliminated entirely.
AIRFLOOR™ is an improved alternative to a hot water radiant system since it has the same radiant benefits plus the cost-saving advantage that both heating and cooling are provided by a single system.
