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 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 1.0 kPa, 2 000 cycles of positive and negative pressure set at 2.56 kPa, and a wind gust of positive and negative pressure set at 3.82 kPa.

Footnote 2

The air leakage rate was determined in accordance with ASTM E 1424-91, "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. 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 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 Demilec spray urethane, the durability of Blueskin® SA was deemed a pass for this application.

Footnote 4

The Sopraseal Stick 1100T has a tri-laminate polyethylene facer that is designed to be compatible with the application spray polyurethane. The durability of other Soprema mod-bit membranes have been evaluated by CCMC, however, this Stick 1100T has not with the spray polyurethane compatible facer. With other performance properties remaining equal, the durability of Sopraseal Stick 1100T was deemed a pass for this application.
