For fiberglass blow-in/loosefill, we trust the durable PROPINK line from Owens Corning. No other loosefill insulation measures up to its coverage, performance and energy efficiency. PROPINK is a non-corrosive and non-combustible material. It resists moisture build-up and mold growth, reduces unwanted noise, does not require wet adhesives and does not settle or deteriorate with age. It’s a great solution for walls, attics, cathedral ceilings and floors.
