InSpire-Solar-Air-Heating-Drying-Metal-Wall-Render

InSpire® Solar Air Heating System is not just a wall panel, this is a solar collector and fresh air heating system. 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 (70% 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.

Traditional InSpire ® utilizes ATAS International’s Belvedere PenumWall profile. For architectural features, InSpire can be implemented using a number of ATAS International metal wall panels to accommodate your design goals.

Now offering a new finish, Selective. What is a selective surface? It’s an optical coating applied to the surface of an element of a solar energy device to reduce thermal radiation losses. Add Selective finish to enhance absorptivity and efficiency to an already solid foundation of the solar collector.

Back-Up Wall Assembly for solar air heating

The Isoleren Insulated Metal Panel Barrier Back Up Wall System provides an alternate all-in-one barrier wall solution vs a traditional multi-component wall system. This system incorporates a single component insulated metal wall panel that supports a secondary metal rainscreen system to meet a wide variety of architectural needs. The Insulated Metal Barrier Back Up panel is thermally efficient and provides the ideal air, vapor, and water barrier that can help reduce construction time by allowing buildings to be “dried-in” faster.
