Oct 15, 2004 Model GR8 Duct System is wrapped in blanket of R8 fiberglass insulation and meets R8 codes. Because air stream is over polyethylene plastic, there is no potential to exhaust fiberglass from within ductwork into living space. System includes fitted elbows and T-joints as well as insulated jackets with adhesive tabs. Snap-in-place lockdown clamp eliminates need for male/female unions and tape, and ensures airtight seal, leak tested to 6 in. water column.
