Product description

The product consists of cellulose fibre insulation that is manufactured in accordance with CAN/ULC-S703-09, “Standard for Cellulose Fibre Insulation (CFI) for Buildings,” and that incorporates approximately 0.5% by weight of powdered adhesive, which is added during the manufacturing process.


This product is evaluated for use in typical wood-frame constructions using either 38 mm × 89 mm or 38 mm × 140 mm studs at 400 mm or 600 mm on centre (o.c.). The wall is provided with a polyethylene vapour barrier on the inside and permeable or semi-permeable sheathing material such as waferboard, fibreboard, glass-fibre thermal insulating sheathing or plywood on the outside.

The insulation is injected into the stud cavities by one of two methods:

  1. Through a polypropylene/polyester woven fabric netting (WallNET®) that is stapled to the face of the studs and plates, which would hold the cellulose insulation in its place (see Figure 1). The vapour barrier is installed afterward in this method.
  2. Through the polyethylene vapour barrier, where vertical splines, horizontal strapping or a combination of both is applied to the vapour barrier prior to installing the cellulose insulation (see Figure 2).

The insulation is applied in a dry state at a density of 45 kg/m3 or in a damp state with a moisture content of 15 ± 4% of dry weight at a density of 48 kg/m3 (with a range of ± 10%). To apply moisture, the dry insulation is misted with water during the installation process to cause the fibre to meld at interstitial points, forming a cohesive mat.

The installation for sloped and cathedral ceilings is the same as for walls (see Figure 3), except that there is a ventilation system. The insulation is always dry-blown into cavities, and for areas that are longer than 3 m the insulation must be blown in by stages.

  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 done by an installer who is certified by CCI Manufacturing Inc. and is performed in accordance with the manufacturer’s installation manual, “WallBAR Insulation System,” December 2016. Installers must carry a certificate bearing their signature. The manufacturer-certified installer is responsible for ensuring that the installation work is carried out in a workmanlike manner and in accordance with recommendations provided by CCI Manufacturing Inc.
  • The product can be applied using any commercially available blowing equipment. The application density can vary depending on the type of blowing apparatus used. The installer should be consulted for the correct application density.
  • The vapour barrier must be resealed with a patch according to the manufacturer’s installation manual.
  • The insulation must be kept away from heat-emitting devices, such as recessed light fixtures, by 75 mm; chimneys and propane or natural gas sources by 50 mm; or the distance required by the local authority having jurisdiction (AHJ).
  • The installer must ensure that the moisture content of the lumber is not greater than 19% after the installation in accordance with Article, Moisture Content, of Division B of the NBC 2015. The moisture content of the wood frame must be verified and recorded by the installer with a moisture meter after installing the insulation.
  • The system can only be used in cathedral ceilings that incorporate a ventilation system constructed in accordance with Subsection 9.19.1., Venting, of Division B of the NBC 2015.
  • Air flow vents for sloped ceilings can be manufactured with 175 B or C unwaxed corrugated cardboard, or expanded polystyrene with a minimum 8 mm thickness at a density of 16 kg/m3, or by stapling WallNET® netting to the face of 25 mm × 50 mm (or better) strapping fastened to the edge of the rafter/truss. Venting should be fastened to roof rafters, truss chords, truss webs, strapping or sheathing using 12 mm staples. The area over the top plate of the exterior wall must be blocked to prevent insulation from spilling into the soffit area.

Material requirements

Thermal insulation

The thermal insulation used is “Weathershield Cellulose Insulation/Sopra-Cellulose W,” CCMC 09218-L, which is compliant with CAN/ULC-S703-09.

Performance requirements

Moisture content, bulge and density

The results for density and moisture content were determined from material taken from three wall cavities with the same dimensions. The insulation was installed in accordance with the manufacturer’s instructions at densities ranging from 48.5 kg/m3 to 51 kg/m3 for dry applications and from 50 kg/m3 to 52.5 kg/m3 for damp applications. Samples from each cavity were taken, conditioned and then weighed to give the results shown in tables below.
