Description
Session 3 will focus on Airtightness specification drawings from a Contractors perspective. Niall Crosson and Joe Fitzgerald will recap on the red line rule for the air barrier line and how to define and review it, along with taking a look at how windtightness is defined and the blue line rule. In this session there will be a demonstration on how drawings are marked up for 3 common build types (Masonry, Timber Frame and CLT) and the strategies to adopt for airtight sealing.
Participants will then have the opportunity to look at elevation drawings with examples of different junctions and mark them up with the help of an experienced technical mentor who will facilitate the process and discussion.
