Cold temperatures make roofing supplies brittle, hard, and unworkable... causing many roofing contractors to close shop during winter months. Warehouse managers are constantly needing improved methods for heating shop materials, fluids, chemicals, and supplies!

Heat Authority's ProMAX HotBox has developed a series of heated wraps and enclosures designed specifically for warehouse and jobsite application. Asphalt shingles, paint, caulking, food products, oil, construction materials and other temperature sensitive and viscous items can now be pre-heated prior to application, producing ideal boundary conditions for product installation.
