1). Start with a high R-value
Let’s begin with the obvious: the more insulation you pack into your Tiny House RV, the more efficient the space will be to heat and cool. For an extreme cold climate, we use rock wool insulation. Unlike a traditional RV that has 5-7 R of insulation a Tumbleweed Tiny House RV has about 17-18 R value. Even though this is lower than home insulation in extreme cold climates, we find that because the space is so small this proves to be enough insulation.
