Knauf Insulation EcoFill Wx blowing wool insulation is an unbonded, virgin fibrous glass blowing insulation having a high degree of post-consumer recycled content, designed for weatherizing and retrofitting existing housing.

Knauf Insulation EcoFill Wx blowing wool insulation is used to dense-pack sidewalls using the drill and fill technique common in retrofitting homes or in home weatherization activities. EcoFill Wx blowing wool insulation is also excellent for doing open blows in attics. This means that only one product is needed to complete an insulation retrofit/weatherization project.

The stated thermal performance of EcoFill Wx blowing wool 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 wall cavities, creating a thermal barrier against outside air and better temperature control
  • Greater resistance to air infiltration than cellulosic materials
  • Resists heat flow with an R-value of R-15 in 2 x 4 construction and R-23 in 2 x 6 construction
  • Absolutely will not settle in walls
  • Will not change from its intended R-value over its lifetime
• 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 - Contains a high degree of recycled glass verified every six months by UL Environment
• Improves Crew Productivity
  
  • Installers spend less time handling bags In a 2,000 square foot home, about 46 bags of EcoFill Wx blowing wool insulation are required, compared to 145 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, EcoFill Wx blowing wool insulation requires no additional fireretardantchemical treatments. Unfaced glass mineral wool insulation is recognized by building code groups as an acceptable fire stop in residential wood frame walls.
• Air Infiltration Resistance - When tested against three cellulose products using ASTM C522, EcoFill Wx blowing wool insulation showed 20 to 100% better air flow resistance than three leading brands.
• Noise Reduction - Improves Sound Transmission Class (STC) ratings by 4 to 10 points, with a 3 point STC change being a noticeable improvement
