Replacing pipe insulation
Hi all -
I am in the process of having the old 1” asbestos pipe insulation (duct tape wrapped) removed from my steam mains and am looking for some feedback as to whether I should replace with 1” fiberglass or go up to 1.5 inch.
The basement is comfortably warm through the winter from the heat loss through the insulation and also from the boiler itself and I’d like to keep it that way. My thought is that if 1” fiberglass has comparable insulation properties to 1” asbestos I should keep it at 1”. If the fiberglass has less insulation value for the same thickness it might make sense to go up to 1.5 inch.
Any feedback appreciated.
