SUMMARY:Crawlspace Retrofits in Electrification Projects: Air Sealing and Insulating
DESCRIPTION:Part 1 of 2 \nCrawlspaces come in all shapes and sizes including shallow or hillside\, and crawlspaces adjacent to conditioned spaces. The geometry of a crawlspace is an important factor when deciding where to establish a continuous air barrier. Ultimately the insulation will follow and remain aligned with that air barrier. In this course\, Dan Perunko of Balance Point Home Performance will present air sealing and insulating strategies for various crawlspace types\, along with the myriad benefits effective crawlspace solutions provide for the occupants and the home. \nAgenda: \n\nIntroduction and safety message\nUnderstanding the geometry of the crawlspace\nUsing test tools identifying leakage and understanding their limitations\nAir barrier alignment for vented and unvented crawlspaces\nImplications for equipment make-up air in unvented crawlspaces\nCreating continuity in the crawlspace\nStrategies for air sealing leaks in the subfloor\nAir sealing around plumbing fixtures that may require future maintenance\nRemoving abandoned or soon-to-be abandoned mechanical equipment that interfaces with the subfloor air barrier\nAir sealing electrical systems and conduits that pass through the subfloor\nAddressing air leakage at masonry fireplaces that pass though the subfloor\n\nThe objective of this course is that at the conclusion\, participants will be able to: \n\nCite areas where the crawlspace air barrier typically lacks continuity\nIdentify tests to assess the continuity of the air barrier\nList examples of crawlspace subfloor penetrations that require an air sealing method that can be undone if maintenance is needed\nName alternatives to batt insulation in the subfloor\nExplain key benefits to air isolating a vented crawlspace from the conditioned spaces\nSummarize post-retrofit testing strategies for continuity and thermal performance
