RCD Corporation's® low VOC Adhesives, Caulks, Mastics, Duct Sealants, and Barrier Coatings create energy efficient buildings by sealing leaking sheet metal ductwork, flexible duct, fiberglass air ducts  and conditioned spaces. Typical residential air ducts leak over 10% of their conditioned air and commercial buildings leak over 15%! Sealing air ducts is recommneded by all power companies and all  building codes require air ducts to be sealed.  HVAC, mechanical and weatherization contractors and do-it-yourselfers (DIY) depend on RCD's high quality products to get the job done right the first time.

RCD Mastics are carefully formulated to provide permanent, air tight, flexible, and weather resistant repairs and installations on HVAC air ducts, thermal insulation, and in conditioned spaces. Sealing leaking air ducts saves energy and reduces our dependence on foreign oil. RCD Corporation® is a member of the U.S. Green Building Council, AIA, and ACCA. Sealing duct leaks in homes, apartments, offices, hospitals, high rises, government and military buildings improves comfort, indoor air quaility and saves energy.
