Sentence 9.25.3.2.(1)

Intent 1:

To limit the probability of an inadequate resistance to air pressure loads, which could lead to:

• the air barrier rupturing, tearing or puncturing at fasteners, or
• the opening of joints in the air barrier.

Where the air barrier system separates a garage, or suite containing a garage, from residential space, this is to limit the probability of a loss of airtightness, which could lead to the leakage of carbon monoxide gas into living space, which could lead to the asphyxiation or acute poisoning of persons.
