For any non-foundation structure, free moving air under the home will affect your indoor heating and cooling. However, because we use spray foam insulation and cover the underside of your tiny home with a critter barrier that doesn’t allow any disruption to the insulation, this is a minor issue for Wind River homes. Additionally, there are endless skirting and decking options that not only add curb appeal to your Wyoming tiny home, but act as a further critter and weather barrier.
