Ontario Building Code
Ruling No. 10-13-250 (13494-R) authorizing the use of this product in Ontario, subject to the terms and conditions contained in the Ruling, was made by the Minister of Municipal Affairs and Housing on 2010-07-13 pursuant to s.29 of the Building Code Act, 1992 (see Ruling for terms and conditions). This Ruling is subject to periodic revisions and updates.
The above opinion is based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.
Product nameEnermax™ (thermal insulation)
The product is a 12.5-mm-thick wood-fibre thermal insulation board with a low-emissivity material (aluminized kraft paper) on one side that is adjacent to a furred-air space assembly. It is manufactured in 1 219 mm × 2 464 mm sheets. The combined assembly is installed on the interior side of a conventional insulated wood-frame structure as described below. The exterior side of the insulated wood-frame structure shall be sheathed with the sheathing specified below.
The wood frame is made of 38-mm × 140-mm studs spaced at 400 mm on centre (o.c.). The stud cavities are filled with friction-fit glass-fibre batt insulation with an RSI of 3.3 at a 140-mm reference thickness. The glass-fibre insulation shall comply with the NBC 2015. The exterior sheathing is BP Sheathing with an 11-mm-thick fibreboard corresponding to CCMC Evaluation Listing 12044-L. The product is nailed on the interior side of the wood studs and the joints are sealed with a 50-mm-wide aluminum tape. The furred-air space assembly consists of 19-mm × 64-mm wood furring strips installed horizontally at 400 mm o.c. and is closed with a gypsum board interior finish. The configuration of the wall system is shown in the figure below.
This evaluation is valid only for products produced at the following plant:

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 product is permitted for use in buildings that fall under the scope of Part 9, Housing and Small Buildings, of the NBC 2015.
- The product must be installed in accordance with the detailed description given in the Product information section of this evaluation, the manufacturer’s application instructions and Part 9 of the NBC 2015. The joints of the product must be sealed with aluminum tape. The product’s aluminum foil surface must be clean and free of defects.
- Attachment of the interior gypsum board, furring and exterior sheathing must comply with the requirements of Part 9 of the NBC 2015.
- The thermal resistance of the wall described in Figure 1 is 4.24 m²·K/W. This value does not take into account interior and exterior air film. See Heat transfer control performance for the design thermal resistance value including the air films. The 4.24 m²·K/W is valid if there are no construction imperfections, no condensation in the cavity and no dust on the surface of the aluminum foil.
Note: Additional insulation material may only be added outboard of the wall system specified in Figure 1. The thermal resistance provided by the additional insulation cannot be added algebraically to the thermal resistance of the wall system. To determine an accurate thermal resistance of the wall system, including an insulation material added outboard of the specified wall system in Figure 1, testing must be conducted.
- The performance of the product as an air barrier material is specified in the CCMC evaluation 13356-R.
- The product must be installed in compliance with the Building Products of Canada’s proprietary air barrier system, which must be approved by the building official. Otherwise, the product application requires a separate air barrier system to comply with Subsection 9.25.3., Air Barrier Systems, of Division B of the NBC 2015.
- The exterior wall sheathing must be the BP Sheathing specified in the Product information section or a board-type sheathing that provides a thermal resistance of at least RSI 0.18 and complies with Subsection 9.23.17., Wall Sheathing, of Division B of the NBC 2015.
- The product must be protected at all times by a 12.7-mm-thick gypsum board interior finish that conforms to Subsection 9.29.5., Gypsum Board Finish (Taped Joints), of Division B of the NBC 2015. The air space must also be sealed at the interior finish to prevent any air change between the furred air space and the interior space. Sealing the air space at the perimeter of the wall, around outlets, etc., must be done in accordance with the manufacturer's installation instructions.
- The heat transfer, water vapour diffusion and air barrier control details between the floor joists at the rim board must meet NBC 2015 requirements.
- The product packaging must include the following information:
- the manufacturer's name or logo; and
- the phrase “CCMC 13494-R” in reference to a drawing of the evaluated wall system including Enermax™ (thermal insulation).
This evaluation is based on demonstrated conformance with the following criteria:
