Air-vapour barriers

Specified air and vapour control layers can help manage air movement, moisture risk, and enclosure durability across transitions and penetrations.

Technical scope

Air-vapour barriers

Specified air and vapour control layers can help manage air movement, moisture risk, and enclosure durability across transitions and penetrations.

Air movement

A continuous air-control layer is designed to limit infiltration and exfiltration through the wall assembly, including transitions and penetrations.

Vapour and condensation

Vapour-control selection and placement depend on climate, assembly design, and material properties so moisture does not become trapped in vulnerable layers.

Project conditions

What we review with you before mobilizing.
  • Membrane family, primer, substrate preparation, laps, terminations, and transitions follow the project specification and manufacturer instructions.
  • We install the membrane system named in the specification, following the manufacturer's installation requirements.
