Features and Benefits

Excellent Thermal Performance
Fills all gaps and voids, creating a thermal barrier against outside air and better temperature control.
Resists heat flow with an R-value of:
R-15 in 2 x 4 construction
R-24 in 2 x 6 construction

One Product, one inventory, two applications.

Energy Conservation
Reduces fuel usage and utility bills for heating and air conditioning.

Each bag contains the equivalent of over 47 recycled bottles, with a minimum of 61.9% post- consumer recycled glass content.

Noise Reduction
Improves Sound Transmission Class (STC) ratings by 4 to 10 points.

Non-combustible, non-corrosive.
Will not rot, mildew or deteriorate.

Blows fast and smooth.

Thermal Performance

Jet Stream MAX Blowing Insulation provides you with a choice of R-values based on the installed thickness and installed weight per square foot. The tables to the right show the minimum requirements for obtaining the desired R-value.

The stated thermal resistance (R-value) is provided by installing the required number of bags per 1,000 sq. ft. 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.

Framing Adjustments

As shown in the table on the last page, to compensate for the framing members in open attic applications, the number of bags per 1,000 sq. ft. of area.

Equipment Required

To achieve labeled R-value, this product must be applied with a pneumatic blowing machine and a corrugated hose with a minimum ?” 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. Acceptable material feed rate is 5-35 lbs./minute. The recommended feed rate is 15-25 lbs./minute. For closed cavity applications, netting must be applied.


Jet Stream MAX Blowing Insulation is packaged in a strong, white, sealed poly bag that offers excellent protection from abuse, dust and moisture.
Knauf Insulation packages are lightweight, stack without slipping and are easy to handle and store.

Fiber Glass and Mold

Fiber glass 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.
