Selatex material under siding
I have a question for you.
I'm going to remove the old aluminum siding and have vinyl put on. AND insulation blown in the side walls after the siding is removed. ( thanks for the previous info)
The question is.... should I remove the old original selatex.. ( the thin black ... not so strong stuff) and replace it with OSB board for better insulation?
Or would that be a waste of time and money.?
