Result

Tested as per CAN/ULC-S741 with five 1-m2 membrane specimens and measured for air permeance at a minimum of six air pressure differentials (ΔP) between 0 and 300 Pa – unconditioned (prior to UV and heat aging).

Air leakage rate at 75 Pa ΔP (based on linear regression of 30 data points) ≤ 0.02 L/(s·m2)

0.0025 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 300 Pa – conditioned (after UV and heat aging).

Where less than 0.01 L/(s·m2) for unconditioned specimens, the increase of the air leakage rate at 75 Pa ΔP for conditioned specimens ≤ 0.001 L/(s·m2).

0.0032 L/(s·m2)Footnote (1)

0.0007 L/(s·m2)Footnote (2)

Water vapour permeance (infiltration direction)

Where less than 60 ng/(Pa·s·m2), the location of the product installation is restricted by the requirements listed in Article 9.25.1.1. of Division B of the NBC 2015.

424.9 ng/(Pa·s·m2)

Water vapour permeance (exfiltration direction)

475.7 ng/(Pa·s·m2)
