Sealing and Insulating Existing Crawl Space Walls - Code Compliance Brief

Publication Date

May, 2016

The intent of this brief is to provide code-related information about sealing and insulating crawl space walls in existing residential buildings to help ensure that the measures will be accepted as being in compliance with the code. Providing the same information to all interested parties (e.g., code officials, builders, contractors, designers, etc.) is expected to result in increased compliance and fewer innovations being questioned at the time of plan review and/or field inspection.
