Product information

Product name

IGLOO Wall Insulation

Product description

The “IGLOO Wall Insulation” system is built on the job site. The system comprises three components: the thermal insulating product, the frame wall construction and the installation method.

The insulating product is the loose-fill cellulose insulation produced by Igloo Cellulose Inc. and bearing the phrase “CCMC 08532-L.” The framing consists of conventional 38-mm × 140-mm or 38-mm × 89-mm wood studs spaced at either 400 mm or 600 mm.

The product is dry-blown using one of two retaining methods: the 360 HD method, which uses a vapour barrier with reinforced vertical strips and horizontal furring, or a knitted membrane method. Each retaining method uses a membrane that permits inspection of the installed product before closing the wall with the interior finishes.

360 HD method

The 360 HD method uses a polyethylene vapour barrier (minimum 6 mil) certified by the Canadian General Standards Board (CGSB). Reinforced vertical strips are stapled every 100 mm with 12.5 mm or larger staples. Wooden furring strips measuring 25 mm × 75 mm are installed horizontally at 400 mm or 600 mm on centre (o.c.). As illustrated in Figure 1, a 75-mm × 75-mm incision is made in the vapour barrier approximately one third from the top of the wall cavity to allow the insertion of a specialized ventilated rotary nozzle (360 HD), which is used to fill the cavity. As the cavity is being filled from the bottom up, the nozzle must be constantly rotated to ensure uniform, high-density compaction of the insulation at a minimum specified design density of 48 kg/m3. An auto adhesive patch is placed over the incision onto the existing vapour barrier.

Knitted membrane method

The knitted membrane method uses netting that is stapled 50 mm o.c. across the interior stud wall. A 75-mm × 75-mm incision is made in the netting approximately 450 mm to 600 mm from the top of the wall cavity. As shown in Figure 2, the hose is inserted through the opening, filling the cavity from the bottom to the top. The vapour barrier is then installed over the membrane.

The installation equipment consists of an adjustable blowing machine and a 75-mm diameter blowing hose with a minimum length of 30 m. By carefully controlling the filling time and filling pressure with the blowing equipment, the cavity will be filled completely to a minimum specified design density of 48 kg/m3.

  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 “IGLOO Wall Insulation” system is designed to act as a thermal insulation in wood-frame walls (the coverage chart is shown in the table below).
  • The thermal insulating product that is used must be cellulose insulation bearing the valid phrase “CCMC 08532-L.” The blowing equipment used shall be approved by Igloo Cellulose Inc.
  • 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 at least 75 mm or the distance required by the local authority having jurisdiction (AHJ).
  • The pierced vapour barrier must be repaired in accordance with current trade practices.
  • The installation must be done by an installer trained by Igloo Cellulose Inc. in accordance with the manufacturer’s current installation instructions and the usage and limitations in this Report. The installer must carry an identification card bearing their photograph and signature issued by Igloo Cellulose Inc.

  Technical information

This evaluation is based on demonstrated conformance with the following criteria:

Performance requirements


The measured densities, which were determined on wall sections using 89-mm- and 140-mm-deep studs spaced at 400 mm and 600 mm, ranged from 55 to 57 kg/m3.

Thermal resistance

The average density used to determine the thermal resistance was approximately 56 kg/m3. The thermal resistance per unit thickness ranged from 25.69 to 25.73 m2·K/W/m. Using 25.7 m2·K/W/m for design calculations, the thermal resistance of the insulation is 3.6 m2·K/W in a 140-mm-thick wall and 2.3 m2·K/W in an 89-mm-thick wall.

This product shall be applied using the following wall coverage chart as a guide.
