	** NOTE TO SPECIFIER ** VTECH Industries ; VTech Skylights products. This section is based on the products of VTECH Industries , which is located at: 5534 Harvey Wilson Dr. Houston, TX 77020 Toll Free Tel: 866-491-0853 Fax: 713-672-7986 Email: request info Web: www.vtechindustries.com [ Click Here ] for additional information. VTECH Industries offers the latest in skylight technology using the Reaction Injection Molding process encapsulating glass and acrylic. Environmentally friendly, designed to bring warmth to your environment using natural light. VTECH Industries has consistently invested in research and development providing advanced manufacturing design and technologies that deliver leak proof skylights at a cost effective price. The utilization of Reaction Injection Molding (RIM) technology combined with a patented aliphatic polyurethane material makes our VTECH Skylights unlike any others on the market today. Encapsulating either glass or acrylic with the aliphatic polyurethane material ensures an absolute water-tight seal. The end result, a single bonded unit. You will not have to worry about leakage - period. The Next Generation Skylight System The Next Generation Skylight System by VTECH sets new standards in the industry. Our new injection molding technology allows you to bring the warmth of natural daylight into your environment with absolutely no leakage or warping . By fusing polyurethane directly to the encapsulated lighting surface, a continuous high performance bond is generated that eliminates the need for a gasket, creating a seal that will not fail due to improper installation, weathering or lack of compression.
