Outside wall sheathing..

After pulling a bunch of plywood out of the tank, we then proceeded to use this on the side of the house. For the curved sections, we are using 11/15 inch / 18.62mm material plywood. However we are doubling this up to provide more strength since this is very thin material and would not add any real structural support. Also, to add incredible strength we are gluing all the plywood and nailing it in place. This will truly add serious rigidity to the walls. This is something normal contractors or builders would not bother doing. Actually, they don't even bother putting real plywood on the outside of the homes. Generally siding can be attached directly here with some bracing only.

Since the tank hole doesn't allow us to remove full 4ft x 8ft sheets we need to trim them to 4ft x 4ft sheets. It actually makes it easier to work with in this case also. Obviously since we're trying to use as much of the plywood we used for the concrete formwork, it looks very ugly on the outside. This will be covered by the tyvek house wrap and no one will see it at that point. Of course over that will come the western red cedar lumber we have ordered. We have chosen "Select Knotty" grade. You can get some idea from the Western Red Cedar Association web link. I would have preferred it without knots, however the price was 2x and really not worthwhile for this project.

We need to cut out the window holes tomorrow since we boarded over them today.

Finished outside view of corner (ugly eh?).

Finished inside view of corner (much nicer without the concrete residue).
