• A high-quality fiber glass batt or roll used in residential construction for thermal and acoustical insulation of walls, ceilings and floors.
• Unfaced insulation is manufactured in increased widths to permit friction-fit installation in wall cavities. This insulation is used with a separate vapor retarder or where a vapor retarder is not required.
• Kraft Faced insulation is manufactured with an integral vapor retarder. The kraft facing includes attachment flanges at the edges that are used for either face or inset stapling. The kraft facing, applied with asphalt to the fiber glass insulation, has a vapor transmission (permeance) rating of one perm or less.

BENEFITS

• Thermally efficient to help fight rising utility bills
• Lightweight and flexible for easy installation
• Good sound absorption; reduces noise level wherever applied
• Inorganic glass fiber is noncorrosive; it will not rot or mildew or otherwise deteriorate
• Does not absorb moisture
• Noncombustible per ASTM E136 (unfaced only)
