  • Publication number: 20140034274
    Abstract: A heat transfer inhibitor system to minimize the heat transfer through the structural opening closures with an interior and an exterior panel such as windows, doors and skylights that are the weak links in interior insulation. By moving a stream of constant temperature air through a space between the external panel and the interior panel, the temperature differential between the exterior surface of the internal panel and the interior is minimized thus reducing the load and maintenance costs on heater/AC systems. It also reduces the required size and costs of installations. Minimizing the resistance to flow of air through the system with butted tubing joints secured with plastic straps and molded deflectors at a specific angle enhance the cost effectiveness of the system.
