This company has created a self-sealing snap-lock pipe called GreenSeam for the environmentally conscious “green” building industry. GreenSeam was developed for high-efficiency systems made to conform to the Leadership in Energy and Environmental Design rating system. According to the company, with increased fuel cost, GreenSeam pipe reduces leakage, which provides higher efficiency and leads to lower energy costs. The installation of GreenSeam is identical to conventional snap-lock pipe, but does not require sealants and tapes. GreenSeam is available in galvanized, aluminum and Type No. 304 stainless steel.
