Results of Testing the Air Leakage Rate of the Product
Type of Wall Tested	Requirement^{Footnote (3)}	Air Leakage Rate After Wind Loading^{Footnote (1)} at 75 Pa ΔP	Air Leakage Rate After Wind Loading at –20°C and at 75 Pa ΔP²
Exterior gypsum/metal stud walls	A1 (≤ 0.05 L/s∙m²∙Pa)	0.023 L/(s·m²)^{Footnote (2)}	0.014 L/(s·m²)^{Footnote (2)}
Concrete masonry units	A1 (≤ 0.05 L/s∙m²∙Pa)	0.016 L/(s·m²)^{Footnote (2)}	0.011 L/(s·m²)^{Footnote (2)}

Notes:

Footnote 1

The air leakage rate of the specimens was determined after structural aging of the air barrier system. Aging of the air barrier system was conducted to qualify it for various Q50 design structural wind loads. The air barrier system was subjected to a loading schedule involving one-hour sustained positive and negative pressure set at 650 Pa, 2 000 cycles of positive and negative pressure set at 950 Pa, wind gust of positive and negative pressure set at 1 410 Pa, and deflection loading at ±1440 Pa for ten seconds.

Footnote 2

The air leakage rate was determined in accordance with ASTM E 1424, "Standard Test Method for Determining the Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure and Temperature Differences Across the Specimen," at an air temperature of –20°C to verify any deformation causing leakage at low temperatures.

Footnote 3

The air leakage rate requirement is based on the Table for Rate of Permissible Air Leakage developed by CCMC/NRC with input from an industry consortium. Information in Table 4.1.1(3) is deemed to meet the intent of the NBC 2015 with regard to air barrier system performance.

Rate of Permissible Air Leakage
Water Vapour Permeance (WVP) of Outermost Layer of Wall Assembly (ng/(Pa·s·m²))	Maximum Permissible Air Leakage Rate (L/s·m²) @ 75 Pa ΔP
15 < WVP ≤ 60	0.05
60 < WVP ≤ 170	0.10
170 < WVP ≤ 800	0.15
> 800	0.20

Results of Testing of Durability of Components in the Product
Component	Requirement	Result
"Wrapsulate® Foam Jacket" polyurethane insulation	Air permeance before and after aging (NRC method): < 10% increase	Passed
"Wrapsulate® Foam Jacket" polyurethane insulation	Thermal resistance after heat aging and weathering: 90% retention	Passed
Transition membrane: "Blueskin SA" by Henry® Company	Physical properties testing^{Footnote (1)}	Passed
Sealant at membrane/foundation junctions: "925 BES" sealant by Henry® Company	ASTM C 920, Type S, Grade NS, Class 35^{Footnote (2)}	Passed
Membrane adhesion to DensGlass® sheathing	ASTM D 3330-04	Determined tension/peel strength values for field quality control

Notes:

Footnote 1

Blueskin SA has been tested to validate several physical properties such as elongation, WVP, puncture resistance, watertightness and crack bridging with a minor durability assessment. However, Blueskin® WP 200 (CCMC 13297-R) has been evaluated by CCMC for durability and is the same membrane technology as Blueskin SA, which is thinner. As the membrane will be protected and insulated by the product, the durability of Blueskin SA was deemed a pass for this application for low rise, 12 m high buildings.

Footnote 2

The sealant manufacturer has tested to ASTM C 920, "Standard Specification for Elastomeric Joint Sealants," as specified in Article 5.9.1.1., Compliance with Applicable Standards, and Sentence 9.27.4.2.(2), Materials, of Division B of the NBC 2015.
