Weekend 2: Subfloor finished!
This weekend was much better for working outside in, as it was a little breezy, and sunny but not beating down. Metal flashing with sun on it is fairly blinding.
Bought the 3/8″ plywood and laid it down, feeling much better about that than only flashing. Finished boxing in the 5 compartments of the trailer, making sure that we “boxed in” the spots for all of our plumbing drains (in our case, the tub and the two sinks, as we will be treating greywater on site for irrigation). No toilet drain needed, as we are going the humanure route (I’ll post pictures of our potty at a later date). We also ran 5/8″ all-thread through the outside stringer in the main compartment, and through both boards in the fender compartments, bolting everything together securely. Another nice feature of the Iron Eagle trailer is that they ask you where you want your bolt holes, and weld washers in place on either side of the box beam so that it is powder coated with the rest of the trailer. That way there is no damage to the finish, and nothing can rust!
A side note: if the ceiling under your loft is only 6’2″-6’4″ as most are, did you think about how your tub drain sticks out? Don’t want to hit your head on the ceiling because you forgot to account for that stupid drain outlet when plumbing in. Of course our tub drain landed exactly on a floor joist, so we had to cut it and box the area in, but better realizing it now than later…
Once the drains were boxed in, the floor screwed together and bolted to the frame, it was time to “sheep and sheet” as we said! The wool smelled like clean sheep, and no gloves, respirator or goggles are required; even the kiddies helped “fluff fluff” the insulation:
As we insulated each compartment we sheeted over everything with 3/4″ thick subfloor plywood, which is expensive but really the best; PAD and Tumbleweed agree on this. I thought maybe 1/2″ thick flooring would be fine, to save on height, but everyone says you’ll feel the floor sag if you do anything less. So shell out for the 3/4″ sheathing!
We were frustrated at first that it took us two whole weekends to do the subflooring, but many tiny housers say it took them more time too, so we are trying not to panic. Since we are doing a curved roof that will probably also slow us down a little as well. But she sure does look good, all fleshed out with no more ribs showing!
