Can I Insulate A Dryer Vent Pipe Hunker
Attach the insulation with a high quality, reinforced foil duct tape. Standard duct tape can heat up and fail over time, so get the good stuff. Wrap everything, including any pliable sections near the dryer, and secure it with the tape. Finally, caulk around the opening where the pipe vents to the outside to prevent any cool air from sneaking in.
