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.

⦿ indicates that the product from this manufacturing facility has been evaluated by the CCMC

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:

Criteria number	Criteria name
CCMC-TG-072123.06-15	CCMC Technical Guide for Loose-Fill Cellulose Insulation System for Walls/Ceilings

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.

Administrative information

Disclaimer

This evaluation is issued by the Canadian Construction Materials Centre (CCMC), a part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:

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

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.
