The Passive House Build, Part Two: Air-Sealed Mudsill Assembly
You only have one chance to get this critical detail perfect.
Synopsis: Part Two of the Passive House Build is devoted to “Air-Sealed Mudsill Assembly.” Architect, Steve Baczek writes that the mudsill is one of the most critical components of a successful Passive House. Airtightness is essential to a Passive House. Minor irregularities of the stemwall or shrinkage of the sill plate once the water and preservative treatment dry alone will make a mudsill prone to gaps, which would pose a major problem to the Passive House design. The article gives a detailed process of assembling an airtight, mudsill sandwich comprised of poly, termite shield, EPDM, Pressure-treated 2×6, and, interestingly enough, acoustical sealant.
