If using as sheathing on a shed, does the interior have to be covered as well or can it be left exposed? I know some foam boards must be covered because of toxin being released in the event of a fire.
Asked by: stereotypicalDIYer
You should not have to cover this on the interior of a shed. This particular product has an very thin layer of aluminum on both sides. Recommend reviewing the product on R-Max website. They have pretty good information there.
