Monitoring Moisture Levels in Double-Stud Walls

Most wood-framed buildings have no insulation on the exterior side of the wall sheathing. Material, usually plywood or oriented strand board (OSB), but sometimes wooden boards, installed on the exterior of wall studs, rafters, or roof trusses; siding or roofing installed on the sheathing—sometimes over strapping to create a rainscreen. That means that the wall sheathing gets cold and wet during the winter.

Aero Barrier system article by Peter Yost, SEON sustainable energy outreach network member

AeroBarrier Air Sealing System

AeroBarrier is a stable, non-toxic, aerosol-applied acrylic sealant.  It is a patented air sealing system that uses a computerized process to pressurize the building and install the AeroBarrier to seal leaks in the building enclosure from the inside.  The particles deposit only at the leak sites and build to form a complete and tight seal, remaining firmly in place for years while staying completely pliable and flexible.  Certainly by reducing air leaks through the building envelope, it is possible to reduce energy loss, help mitigate moisture damage, and enhance overall comfort and health of the building.
