Used for connecting exhaust blowers to air cooled grow lights and venting. The insulated duct tube keeps the heat from the lights from escaping into the grow room with the R-4.2 insulation. The sound from the exhaust blowers is also significantly reduced. The inner surface is quite smooth compared to low cost white vinyl tubing. Black polyester inner tube with a fiberglass wrap covered with a metalized polyester (mylar) outer wrap.
