What This Presentation Covers:
Builders and designers continue to push towards higher levels of airtightness, raising new questions about the impact of different materials and design choices. At passive house levels, every decision can feel critical. Well-designed research and testing can help sort out what really matters, bringing the big picture into focus and supporting evidence-based decision-making.
In this presentation, we’ll take a look at an example of a real-world observation and the question it raised: does the air permeance of sheathing material matter for airtightness? Join us to find out how we got to an answer, focusing on typical assemblies for low- to mid-rise wood-framed buildings.
