Notes:

Footnote 1

The air leakage rate of the specimens is determined after structural aging of the air barrier system. Aging of the air barrier system was conducted to qualify it for a design structural wind load of Q50 = 0.55 kPa (NBC climatic data in Appendix C) for a 1-in-50 year return period. The air barrier system was subjected to a loading schedule involving one-hour sustained positive and negative pressure set at 0.55 kPa, 2 000 cycles of positive and negative pressure set at 0.80 kPa, and a wind gust of positive and negative pressure set at 1.2 kPa.

Footnote 2

The air leakage rate was determined in accordance with ASTM E1424-91(2008), "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 performance results in a Classification A1 as per CAN/ULC-S742-11, "Standard for Air Barrier Assemblies – Specification." The air leakage rate criteria is based on the permissible air leakage rates shown in Table 4.1.2, which are considered to be in accordance with the NBC in regard to the air barrier system performance and drying potential of the wall assembly.

Notes:

Footnote 1

The results of the testing were deemed a pass when reviewing the low air leakage performance and considering the error and bias of the test procedure.

Footnote 2

The thermal testing results after aging varied, but remained within the expectations of the published LTTR value.

Footnote 3

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 ProSeal spray urethane, the durability of Blueskin SA was deemed a pass for this application for low rise, 12 m high buildings.
