Finishing the Modular Cabin On-site Connection

Finishing the Modular Cabin On-site Connection

The carpenter finished the area where the cabin is attached to the foundation. This is the part of the process I have had the most questions about, so I’m telling you everything I’ve seen.

The cabin is attached to the foundation and has passed another inspection, so we can move on and cover the work.

They filled the gaps with pressure treated wood to make an even surface for the ZIP System OSB

The carpenter added PT (pressure treated) wood between the rails so that there is  an even surface to nail to.

Next the plan calls for OSB Filler to attach to the perimeter rail and sill plate.

OSB is Oriented Strand Board or Particle Board, engineered wood manufactured from waterproof heat-cured adhesives and wood strands that are arranged in cross-oriented layers.

They covered the side of the sill plate and cabin rail with ZIP System OSB

Taylor (Fowler Excavating) used ZIP System OSB. It adds insulation.

ZIP System R-sheathing is the simple all-in-one structural panel with built-in exterior insulation. Featuring integrated moisture, air and thermal protection, ZIP System R-sheathing completely reimagines traditional wall assemblies by streamlining exterior water, air and thermal management.

ZIP System OSB Filler is attached to the perimeter rail and sill plate.

The carpenter built landings for the front and back doors. We plan to have a porch and a carport, but this will be enough (once the steps are done) to pass inspection and get a CO.

Then 1 x 12 Pressure Treated Decorative Trim Boards covers it all. Westwood Cabins provided the trim. It was already pre-primed and ready for paint.

It only took about an hour to paint the trim and clean up.

We saved some money by painting it ourselves later.
