I finished insulating the tiny house today. Yesterday we bought some polystyrene sheets at $4.50 each (30 of them), to use for the interior walls. They are white on one side and actually have a layer of thin plastic, so they should be easy to keep clean. They will break easily if we fall into them, but most of the wall space will be behind furniture, so we should be okay. I think we’ll have a few extras for serious breakage.

We also bought three more sheets of styrofoam – 4×8 sheets this time. It was just enough to make up for all the pieces that were missing. I got most of it done yesterday before play practice, but I went back today and finished it entirely. I discovered along the way that the best way to keep them in place was to put styrofoam “shims” in all the spaces where they were a little loose. So they are all held nicely in place now. But Don is still going to hold each row with a 1″x1″ strip. That strip will also be what we nail or screw the polystyrene sheets to. I think it is going to work out well. It will also give us somewhere to put hooks or hang pictures or clocks or the such. I’m getting excited about how nice it is going to turn out!

Don also got the electric line buried and hooked up to the tiny house, so we have a couple of outlets and two overhead lights that work! There is also an exterior outlet on the house, so we can run an extension cord from that to the tiny house if we need things on more than one circuit.
