Retrofitting Crawlspaces: Air Sealing and Insulating Crawlspace Subfloors - Part 4 of 6

Thursday, March 23, 2023 (8:00 AM - 12:00 PM) (PDT)


Part 4 of 6 - March 23, 2023 (8am - 12pm) Testing your work is imperative to meeting or exceeding performance targets and ensuring a feedback loop is in place for continual process improvements. This four-hour class assumes that you have made the decision to align your air and thermal boundary at the subfloor of the crawlspace (rather than at the exterior walls and on grade). For most homes that have a raised floor, this is where the air and thermal boundary is typically located. 

The way that the subfloor is constructed depends on the era that home was built in. Instructor Gavin Healy of Balance Point Home Performance will cover the most appropriate air sealing tactics for common subfloor systems built over the last two centuries. Once we have established an effective air barrier, we will cover how to overcome the tendency for subfloor insulation to fail based on gravity and poor installation techniques.
