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.

  Technical information

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

Performance requirements

Density

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.

Code compliance as an acceptable solution

Code Compliance via Acceptable Solutions

If a building design (e.g. material, component, assembly or system) can be shown to meet all provisions of the applicable acceptable solutions in Division B (e.g. it complies with the applicable provisions of a referenced standard), it is deemed to have satisfied the objectives and functional statements linked to those provisions and thus to have complied with that part of the Code.

National Building Code of Canada, Sentence A-1.2.1.1.(1)(a)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Acceptable Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

  • complying with the applicable acceptable solutions in Division B, or
  • using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.

Code compliance as an alternative solution

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions
