Worried about heat loss and condensation build up on your ducts? Make sure to use Dundas Jafine's BIS insulated sleeves, which help prevent heat loss and condensation build up. The air duct insulation sleeves consist of a thick glass fibre insulating blanket, jacketed by a heavy polyethylene vapour barrier or tear resistant silver vapour barrier liner. Both components of the product contain the same fire retardants found in Dundas Jafine's UL 181 approved flexible insulted ducting and are available in a wide variety of sizes to suit your job.
