Preserved Wood Foundations

#1 Framing the Wall

The wall will be framed, but not sheathed, complete with opening and framing clips for the opening. Then the wall will be fastened to the Preserved Wood Foundation footing plate which may include a bracing system. During the demonstration there will be a brief overview of Preserved Wood Foundation construction.

#2 Sheath & Damp Proof the Wall

Install the sheathing on the wall, also demonstrating the spacing and sealing at joints both horizontal and vertical. Install the 6 mil poly damp proofing. Install and seal the 1/2" Preserved Wood Foundation plywood grade strip. In the demonstration there will be discussion on the orientation of the sheathing and how the backfill heights affect the required sheathing thickness the times when the sheathing fastening requirements can change and the requirements for laps, sealing and the fold down at the top.

#3 Install Outlet & Insulate the Wall

Install an electrical outlet in a box, with poly hat for the Air Vapour Barrier, and run a feed wire for it through the top plate. Insulate the wall stud cavities, showing proper techniques for fitting insulation and insulating around electrical boxes and wires. In the demonstration there will be discussion about the Preserved Wood Foundation specific requirements for running electrical and other services and the option for insulating the lintel space.

#4 Install the Air Vapour Barrier & Framing Straps

Install the Air Vapour Barrier, paying special attention to the electrical penetration and window opening. Seal the wiring penetration with foam or acoustic sealant. Install framing straps to each foundation wall stud. During the demonstration there will be discussion about Air Vapour Barrier building science and how to properly install and seal and framing strap requirements.
