“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. To achieve stated R-values, the insulation must be installed at stated minimal thicknesses and maximum coverages. Stated R-value will be reduced with the use of re-feed material. Field manufacturing variables such as density and installation techniques may affect stated R-values. Following recommended manufacturer’s installation guidelines will minimize application variances. Field blending of this product with other loose fill insulations or application of this product in conjunction with adhesive or binder systems may affect its thermal performance and is not recommended by the manufacturer. To achieve stated R-values, this product must be applied with a Knauf-approved pneumatic blowing machine equipped with a fluid delivery system, a collector box and a corrugated hose with a minimum 1/4" internal corrugation and a minimum length of 150'. Additional equipment needed to finish wall sections would include an approved spray nozzle, wall scrubber, and a vacuum. See list of Knauf-approved equipment for installing Jet Spray Thermal.
