DATA SHEET
EcoFill ® Wx Blowing Insulation
DESCRIPTION
EcoFill Wx blowing insulation is an unbonded, fiberglass blowing insulation with a high degree of recycled content, designed for weatherizing and retrofitting existing housing or new construction.
APPLICATION
• Open blows in attics
• Dense-pack sidewalls using the drill-and fill-technique
SPECIFICATION COMPLIANCE
• ASTM C764; Type I
• HH-I-1030B; Class B Certified
• Meets the Quality Standards of the State of California
INDOOR AIR QUALITY
• UL Environment
• GREENGUARD Certified
• GREENGUARD Gold Certified
• Validated to be Formaldehyde-Free
• EUCEB Certified
FIBERGLASS AND MOLD
Fiberglass insulation will not sustain mold growth. However, mold can grow on almost any material when it becomes wet and contaminated. Carefully inspect any insulation that has been exposed to water. If it shows any sign of mold it must be discarded. If the material is wet but shows no evidence of mold, it should be dried rapidly and thoroughly. If it shows signs of facing degradation from wetting, it should be replaced.

DOING MORE FOR THE WORLD WE LIVE IN.
All of our products are made from sustainable resources, such as recycled glass and sand. And we’re proud to be putting glass bottles back to work rather than into landfills. Our products are made with a minimum of 50% recycled glass—totaling an average of 26 million bottles each month.

THERMAL PERFORMANCE
The stated thermal resistance (R-value) is provided by installing the required number of bags per 1,000 square feet of net area, at not less than the labeled minimum thickness (per the manufacturer’s instructions). Failure to install both the required number of bags and at least the minimum thickness will result in lower insulation R-values.
Field blending of this product with other loose fill insulation or application of this product in conjunction with adhesive or binder systems may affect its thermal performance and is not recommended by the manufacturer.
EQUIPMENT REQUIRED
To achieve labeled R-value, this product must be applied with a pneumatic blowing machine and a corrugated hose with a minimum 0.25" internal corrugation, a minimum length of 150' and a diameter of at least 3". Coils in the hose should not be less than 36" in diameter. The recommended feed rate is 15–25 lbs./min. For closed cavity applications, fabric or netting must be applied.

Coverage and installation data were determined using a Volu-Matic ® III blowing machine in third gear with 13" gate opening, 2.5–3.0 PSI air pressure, 150' of 3" diameter internally-corrugated hose. Volu-Matic III is a registered trademark of CertainTeed Corporation.
*“R” means resistance to heat flow. The higher the R-value, the greater the insulating power. To get the marked R-value, it is essential that this insulation be installed properly.
If you do it yourself, get instructions and follow them carefully. Instructions do not come with this package.
**Based on Third Party 10-year settling study, the predicted settlement over a 20-year period would be 1 percent or less. This amount of settling is thermally insignificant.
Therefore, the installed and settled thicknesses are effectively the same.
