Air Sealing

Mudsills - Where the Framing Meets the Foundation

January 21, 2011 by Anne

The framing meets the foundation at the mudsill and the space between them can be the cause of serious air leaks which transport moisture and waste heating/cooling energy.  In order to insure an airtight crawl space we made a tight seal between the mudsill and the top of the foundation by placing polyethylene sheeting between the mud sill and the top of the foundation.
