        Answer This Question

        A:  Hello Shield, Pole barns are not typically designed to be insulated. Owens Corning does not have set recommendations for insulating pole barns because of this. We suggest contacting the manufacturer of the pole barn for their recommendations regarding insulation or there are contractors/companies that specialize in insulating pole barns that you may contact. Thank you for your inquiry!

        by|Dec 28, 2020

          A:  There is a YouTube channel, RRBuilding(?), that does post frame construction, and has one titled, ?Don?t call it a Pole Barn?. They?ve got lots of good info on the type of construction you seem to be referring to.

            Terrific density
            Fits between studs perfect. Wear thick gloves. There are large glass chunks in the fibers.

            Easy insulation
            I went with mineral wool because mildew resistant and practically fire proof. You can cut the material that ever size you need. I cut it using a bread knife. Literally like cutting butter with a hot knife. I flew in my insulation project in a few hours. I was insulating between the joist and the foundation wall. Easy pizzy even in the crawl space.
