Product information

Product names

  • Knauf JetStream® MAX Blowing Insulation Wall System
  • Sidewall Blowing Insulation

Product description

The system is assembled on the job site and is intended for use in wood-frame constructions. The wall system uses a mesh that is stapled to the wood-frame members to contain the dry-blown mineral fibre insulation material. The insulation is injected into the wall, sloped ceiling or attic cavity with a manufacturer-recommended blowing machine (see Figure 1 and Figure 2). The thermal insulation used is Knauf JetStream® MAX (see CCMC 13404-L).

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The installation of the product must be carried out by Knauf Insulation installers.
  • The thermal insulation product must be delivered to the building site in unopened packages. The mesh must bulge less than 13 mm beyond the stud to indicate a conforming installation that provides the necessary product density.
  • The insulation must be kept away from heat-emitting devices, such as recessed light fixtures, chimneys, and propane or natural gas sources, at a distance of 75 mm or the distance required by the local authority having jurisdiction (AHJ).
  • If the system is installed in cathedral ceilings, there must be a ventilation system constructed in accordance with Subsection 9.19.1., Venting, of Division B of the NBC 2015.
  • The installation must be in accordance with the manufacturer’s installation instructions and as described in this evaluation.
  • Table 1 indicates the coverage for installation in attics and walls.
