Air Ducts Leak. Sealing heating and cooling air ducts with RCD Mastics saves energy and allows central air conditioning units, heat pumps, and furnaces to operate efficiently. RCD Corporation adhesives, caulks, mastics, duct sealants and insulation coatings save energy by sealing leaking sheet metal ductwork, flexible duct and fiberglass ducts. Repairing leaky ductwork and crawl spaces improves indoor air quality and saves electricity. HVAC contractors, mechanical contractors and weatherization contractors depend on RCD water-borne building products.
RCD Mastics save energy by preventing heat gain or loss and provide permanent, air tight, flexible, and weather resistant repairs and installations on HVAC air ducts, thermal insulation, and crawl spaces. RCD adhesives, duct sealants and mastics earn LEED Credits, are low odor, low VOC and easy to use. Sealing leaking air ducts can be a do-it-yourself project. Sealing duct leaks in homes, apartments, offices, hospitals, high rises, government and military buildings improves comfort, indoor air quaility and saves energy.
