10 Inch Ventlon (Short Roll)
Ventlon®, a heavy glass fabric, double coated with Hypalon®/CSM (chlorosulfurated polyethylene), is air-tight, water-tight and fire retardant. Fabrics coated with Hypalon® have superb resistance to sunlight, ozone and weather. In fact, duPont’s brochure #E11875 states that the ability of Hypalon® synthetic rubber to resist the long term effects of weathering is documented by 30 year old exposure tests.
Ventlon® is accepted by the National Fire Protection Association for vibration isolation connectors in duct systems, in accordance with ANSI/NFPA 701
