I am collecting materials to build a tiny house. So far I have a used steel trailer frame from a mobile home, and some recovered lumber and steel siding. I am going to put the electrical wiring in the baseboard. The outside of the walls will be the steel siding, the inside will be some kind of
wood. Because the wiring is not going to be in the walls, each section is going to be a sealed area (no gaps for outlets, etc) with post recycled consumer cotton waste as insulation.
Should I install a small vent inside near the bottom of each 16" wall section to facilitate breathing? I am also going to paint the walls inside and out with primer and sealer to help prevent leakage and
water damage. Are there any environmentally friendly products that will do the job?
