AT3: Airtightness specification drawings – the process from a contractor’s perspective
November 22 @ 9:00 am - 11:00 am
A new series delivered over four sessions, each lasting two hours. Each event can be attended as a stand alone course or, if attending the whole series they will compliment each other.
There will be a recap on the red line rule for the air barrier line and how to define and review it. Also taking a brief look at wind tightness, how it’s defined, and looking at the blue line rule. In the first part of this session, we will demonstrate how drawings are marked for 3 common building types and the strategies to adopt for sealing; CLT, Timber Frame and Masonry. Define the air barrier line and all the connections, how they are made, what the air barrier is and how it connects to the different components.
In the second part of this third session, delegates can choose a Breakout room with a build type, Block, Timber Frame, or CLT and look at elevation drawings with examples of different junctions and mark them up live. An experienced technical mentor will work along side each group to facilitate the process and discussion.
At the end of this session, each breakout group will come back to the main group to summarise their drawings and give feedback on their airtightness conclusions and solutions.
This session will show why an Airtightness Champion is key to success. Showing that communication and coordination to interpret drawings and create an airtightness strategy on site among different construction disciplines is key.
