National Building Code of Canada 2015
|ID||Code provision||Solution type|
|05-04-01-02-00-0-00||22.214.171.124. Air Barrier System Properties||Alternative|
|09-29-08-01-00-0-00||126.96.36.199. Material Standard||Acceptable|
Ontario Building Code
Ruling No. 09-31-229 (13356-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 2009-12-02 (revised 2010-06-22) 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 descriptionThis Report addresses the performance of “Enermax” as an air barrier material. The product is a wood-fibre thermal insulation board manufactured from non-toxic organic wood fibres and laminated on one side with an aluminum membrane using water-soluble glue. The product is 12.7 mm thick, and the panels are available in 1.232 m × 3.657 m and 1.219 m × 2.463 m sizes. The product meets CAN/ULC-S706- 09, “Wood Fibre Insulating Boards for Buildings,” and is installed on the warm side of the exterior wood-frame wall.
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 capable of being the principal plane of airtightness in an air barrier system by demonstrating a sufficiently low air permeance, equivalent to the materials referred to in Sentence 188.8.131.52.(1) of Division B of the NBC 2015.
- When the product is installed as part of the airtight element in the designated air barrier system, the vapour barrier must comply with Sentences 184.108.40.206.(1), (2), (5) and (6), Vapour Barrier Materials, of Division B of the NBC 2015. In cases where an alternative low water vapour permeance element has been installed in the wall assembly, Sentences 220.127.116.11.(3) and (4) apply.
- A conforming installation must be installed:
- with the printed side visible and protected from exposure to ultraviolet (UV) radiation from the sun within 60 days; and
- in accordance with Building Products of Canada Corp.'s “Enermax” Application Instructions. Examples of the installation details are presented as Additional Information in Appendix A of this Report.
This evaluation is based on demonstrated conformance with the following criteria:
|Criteria number||Criteria name|
|CCMC-TG-072709.02-15A||CCMC Technical Guide for Fibreboard Air Barrier Materials|
The Report Holder has submitted technical documentation for the CCMC’s evaluation. Testing was conducted at laboratories recognized by the CCMC. The corresponding technical evidence for this product is summarized below
|Five 1-m2-membrane specimens tested and measured for air permeance at a minimum of six air pressure differentials (DP) between 0 and 250 Pa||unconditioned specimens||≤ 0.02 L/(s·m2)||0.0001 L/(s·m2)|
|Five 1-m2-membrane specimens tested and measured for air permeance at a minimum of six air pressure differentials (ΔP) between 0 and 250 Pa||conditioned specimens||Where less than 0.01 L/(s·m2) for unconditioned specimens, the air leakage rate for conditioned specimens must not increase by more than 0.001 L/(s·m2) at 75 Pa pressure difference.||Pass|

Appendix A - additional information
An air barrier material as part of an air barrier system
The CCMC has not evaluated the performance of the “Enermax” air barrier system for its conformance with Article 18.104.22.168., Air Barrier System Properties, of Division B of the NBC 2015. However, the CCMC’s opinion is that an air barrier system using this material and installed in conformance with the details outlined below, as well as in conformance with Building Products of Canada Corp.'s “Enermax” Application Instructions, should satisfy the requirements for continuity of the air barrier system stated in Articles 22.214.171.124., Required Barrier to Air Leakage, and 126.96.36.199., Continuity of the Air Barrier System, of Division B of the NBC 2015.
The CCMC’s evaluation of this material does not include the evaluation of its strength or the strength of the continuity details. The authority having jurisdiction (AHJ) must therefore determine whether an air barrier system that uses the product as described herein meets the intent of Sentence 188.8.131.52.(1) of Division B of the NBC 2015, as being an effective barrier for the proposed construction in its geographical/climate area. For example, the AHJ may deem the proposed air barrier system adequate for buildings in urban areas, sheltered sites, or areas of low wind, but inadequate in areas of high wind and exposed sites in rural or coastal areas.
The following air barrier system checklist is to be considered by the AHJ. An air barrier system must:
- have an acceptable low air leakage rate;
- be continuous;
- be durable;
- have sufficient strength to resist the anticipated air pressure load; and
- be buildable in the field
The product is attached to the inside face of the wood-frame wall. However, it does not contribute to an air barrier system until it is joined to the other components that make up the air barrier system of the building. Building Products of Canada Corp.'s “Enermax” Application Instructions outline how the product’s material must be joined to the foundation wall, the windows and doors, the penetrations in the wall, and the ceiling air barrier to form the system.
A successful air barrier system installation depends on coordination during construction. Coordination is required during erection of the framing and after completion of the air barrier system to ensure that no other trade breaches the integrity of the installed air barrier system.
The “Enermax” air barrier system is defined as possessing the following features:
- it has “Enermax” material as the principal plane of airtightness;
- its accessories include sealants, tape, foam and gaskets to maintain continuity at junctions with penetrations in the wall assembly (i.e., windows, doors, pipes, ducts, electrical outlets, etc.);
- it is durable, meeting CAN/ULC-S706;
- it has an interior board with specified fasteners and a fastening schedule as per Building Products of Canada Corp.'s “Enermax” Application Instructions; and
- it is buildable in the field by knowledgeable builders following Building Products of Canada Corp.'s “Enermax” Application Instructions, and is reviewed by building officials.
The figures below outline typical construction details for the installation of the proposed air barrier system in the field. See Building Products of Canada Corp.'s “Enermax” Application Instructions for additional details.
