Air barrier strategy
Deciding what sealing products and processes are required to deliver the target airtightness leads to the development of a formal air barrier strategy. For clarity and ease of communication, we suggest that this is summarised in the manner shown below, tailored for an individual project:
For a specific project the manufacturer of sealing tapes and airtightness membranes should be detailed, and a list of penetrations and how they are to be sealed would also be needed. Your project would be individual and almost certainly different, but summarising it in this way is an essential step in communicating how the Passivhaus target is to be achieved. The next step should be to prepare a set of airtightness drawings, detailing the line of the airtightness barrier on plans and sections.
