RCD Corporation's® low VOC Mastics, Duct Sealants, and Barrier Coatings help create energy efficient residential, commercial, industrial, and institutional buildings by preventing heat gain or heat loss by sealing leaking air ducts and conditioned spaces. Typical residential air ducts leak over 10% of their conditioned air. Even worse – commercial and institutional buildings leak over 15%! The U.S. Environmental Protection Agency's Energy Star® Program recommends sealing air ducts as does the U.S. Department of Energy's Energy Efficiency and Renewable Energy program. All  state, national, and international  building codes require air ducts to be sealed.  Professionals and do-it-yourselfers (DIY) alike 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.
