We got the trailer moved back up to Sue and Jesse’s place. (It’s been in our driveway for the last few weeks). They were generous enough to offer us space in the shop so that we can work on it through the winter.
When we ordered the trailer we decided to have it built without wheel wells and to build our own. We do a lot of surfing around the nets to read other tiny home-builders’ experiences and we have read that there are issues with the metal wheel wells on trailers and water seeping into the structure.
So, to start the wheel wells, Mr. Hart bolted on some pressure treated 2x6s to cap off the outside of the rail next the the wheels. This will offer a place to attach some metal to line the wheel wells, and also to attach the plywood subfloor.
We are so excited about our decision to go with wool insulation. We found a company near Portland, Oregon Shepherd, that produces an insulation made entirely out of sheep’s wool. We were looking for a product that would not off-gas in our tiny living space, something we need to be concerned about since the space is so tiny. We are psyched that it is a local company that raise the sheep themselves, plus it’s wool! How cool! And warm! (Oh no, not funny).
So we called the company and were amazed to find out that they have a special package designed specifically for a project like ours, a tiny-home-on-a-trailer. What a nice surprise, they had done this before.
We ordered enough wool to insulate the floor and it came in three big boxes that sat in our living room for a couple of weeks.
We couldn’t wait to break into it to feel it, so we did that right away.
One cool characteristic of wool that helped solidify our decision to use it is that it wicks moisture, thereby controlling condensation. Apparently, condensation and moisture are issues common to living in such small spaces and the wool will contribute in helping us battle some of that.
We are really stoked about benefitting from two other cool properties of wool insulation. One is that wool expands over time, filling in all small gaps and crevices, as opposed to other loose insulation that packs down over time leaving you with air spaces. (No, Caleb, it will not eventually blow the trailer apart, expansion is minimal, not destructive.) The other is that we were able to overpack the space to get a considerably higher r-value than the product lists.
Here’s the pic that shows the pressure treated wood on the wheel wells and the insulation. Mr. Hart spread it in by hand, although you can blow it in too, but it was such a small area that it seemed totally doable. And it was. And he says it was fun, too, like petting sheep for an hour…uh…no, not like that you perverts!
