ProPink® L77 Product Features

Highest Coverage - Provides the highest yield per bag of any loosefill insulation available. In fact, one 32-lb bag of Owens Corning® insulation can cover 77 square feet at R-30.
Exceptional Thermal Protection - Completely fills the cavity and eliminates gaps that require additional handwork.
Design Integrity - Offers virtually no settling, enabling you to achieve high-quality, inspection-ready installs.
Excellent Sustainability - Formaldehyde-free, GREENGUARD® Gold Certified, and certified 55% recycled content.
NFPA 13 Standard - Meets standards for non-combustible insulation as an alternative to mid-floor sprinklers.
Non combustible non-corrosive and validated to be formaldehyde free.¹
Able to be blown into walls at 2.5 lb density to provide equivalent airflow reduction and create greater R-value than cellulose in walls.
Resistance to moisture, fungus and mold growth.²

Owens Corning® L77 ULF is validated formaldehyde free by the UL Environment.
As manufactured fiberglass insulation is resistant to mold growth. (ASTM C1338-96 Fungi Resistance of Insulation Materials and Facings.) However, mold growth can occur on building materials, including insulation, when it becomes contaminated with organic material and when water is present. To avoid mold growth on fiber glass insulation, remove any water that has accumulated and correct or repair the source of that water as soon as possible. Insulation that has become wet should be inspected for evidence of residual moisture and contamination, and any insulation that is contaminated should be promptly removed and replaced.
