Heating Duct Insulation
If your heating duct work is made out of fibered insulation duct board, every time your furnace kicks on it blows air across these fibers in the insulation. This can cause respiratory and itching problems, especially in children and the elderly. It is much better to use metal furnace pipe and seal all the seams good, then insulate the outside, preferably with a thick foam type insulation. Fiberglass type insulation works good, but it always needs to be sealed away from the living area. See you next time.
