Knauf Insulation Blowing Insulation is an unbonded, virgin fibrous glass blowing insulation having a high degree of postconsumer recycled content.

Knauf Insulation Blowing Insulation is used in residential and commercial construction as a thermal and acoustical insulation. It is designed for pneumatic installation in open attic or ceiling plenum areas with flat flooring or up to a maximum slope of 4.5:12.

The stated thermal performance of Knauf Insulation Blowing Insulation requires installation in accordance with the manufacturer’s instructions. Failure to install the material properly will impact the performance of this product. This product must be installed according to the coverage charts provided.

Features

• Excellent Thermal Properties
  
  • Fills all gaps and voids in ceilings, creating a thermal barrier against outside air and better temperature control
  • Greater resistance to air infiltration than cellulosic materials
  • Will not change from its intended R-value over its lifetime
  • Will not settle
• Saves Warehouse and Truck Space - Requires about one-half of the warehouse and truck space of competing cellulosic products
• Better Coverage than Cellulose - More than 2x the coverage per bag
• Sustainable - Made from a high degree of recycled content
• Improves Crew Productivity
  
  • Installers spend less time handling bags. In a 2,000 square foot home, about 50 bags of Knauf Insulation Blowing Insulation are required, compared to 100 bags of cellulosic material
  • Installs cleaner than cellulose, virtually dust-free
  • Blows clean and smooth and does not require stabilizing
• Strong Poly Bag Packaging - Packaged in a very strong poly bag that prevents bag breakage and jobsite spillage. The bags stack well and have a coefficient of friction sufficient to reduce slippage.
• Non-combustible - Glass mineral wool is naturally noncombustible and remains so for the life of the product. Unlike cellulose, Knauf Insulation Blowing Insulation requires no additional fireretardant chemical treatments. Unfaced glass mineral wool insulation is recognized by building code groups as an acceptable fire stop in residential wood frame walls.
• Noise Reduction - Improves Sound Transmission Class (STC) ratings by 4 to 10 points, with a 3 point STC change being a noticeable improvement
