These past few days we have been working on finishing the floor of the tiny house. The spaces between the floor joists have OSB planks to fit in between them and are nailed in place. We are now working on doing the insulation and we have chosen to use two different types if insulation for the floor. The types that we chose are R-11 foam insulation and some thinner fiberglass insulation, which has a three to four r value, like what you would see in a wall. The foam insulation has to be cut to fit exactly in the space between joists but the fiberglass insulation can be a little bit over sized to make sure it is sealed better. The next steps for the tiny house floor is finishing the insulation and then adding the top decking of more OSB before we attach it to the frame of the trailer.
