High Performance Crawl Spaces: a practical approach to air sealing and insulating.

March 28

This eight hour class is a comprehensive class focused on applying building science principles to
California crawlspaces. Frequently crawls performance issues must be addressed prior to air
sealing the building enclosure to avoid poor moisture balance in the house.

The class will cover moisture management with targets, measurement and monitoring. We will review techniques for drying out wet crawlspaces. We will cover commissioning of mechanically vented crawlspaces.

It will address the field application of insulation systems that are durable and appropriate to
individual surfaces. The class will cover management of continuity in the air and thermal
boundary at crawlspace stem walls that are adjacent to conditioned zones such as daylight
basements. The class will cover the integration of soil gas and chemical vapor mitigation
systems where necessary and appropriate.

Discussion will focus on real world instillation techniques for managing the wide array of complex floor assemblies found on California homes built on steep topography. In the class we will evaluate how material choices impact the pressure and thermal boundary of the building. The instructor will share insights on converting vented crawlspaces to unvented and conditioned crawlspaces. The class will cover thermal, air and bulk water control strategies for maintaining building durability. Finally the class will cover the test methods for ensuring the integrity of the air barrier before it’s too late. The class covers specifications and instillation strategies that will benefit general contractors, designers, and insulation companies, and owner builders.
