Knauf Jet Stream® 73.3 Blowing Wool

Description

Knauf JET STREAM^® 73.3 Fiber Glass Blowing Insulation is an unbonded, virgin fibrous glass blowing insulation designed with optimal thermal properties, and excellent coverage and blowing characteristics. Jet Stream 73.3's unique platinum color identities it as the high performing product that you require.

Application

Knauf JET STREAM 73.3 Fiber Glass Blowing Insulation is typically installed in open attics of both new and existing structures. It can also be used in retrofit closed-cavity applications such as exterior sidewalls or floored attics. Loose-fill blowing insulation is intended for use where pneumatically installed insulation is most cost-effective.

Features and Benefits

Installation

Blows fast and smooth.
Clean, white, professional-looking appearance.
Processes better than a bag a minute.

Permanence

Noncombustible, non-corrosive.
Will not rot, mildew, or deteriorate.

Thermal Performance

Knauf JET STREAM 73.3 Fiber Glass Blowing Insulation provides you a choice of R-values based on the installed thickness and the installed weight per square foot. The tables below show the minimum requirements for obtaining the desired R-value. The stated thermal resistance (R-value) is provided by installing in accordance with the manufacturer's instructions, the required number of bags per 1,000 sq. ft. of net area, at not less than the labeled minimum thickness.

Jet Stream 73.3's new 32 pound bag gives you coverage of 73.3 square feet at R-30. Failure to install both the required number of bags and at least the minimum thickness will result in lower insulation R-values.

Coverage and installation data were determined using a Volu-Matic^® II blowing machine in 3rd gear with 13" gate opening, 2.0 psi air pressure, 150' of 3" diameter internally-corrugated hose.

* "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 a third party 2-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.
