We wrapped the interior in 4 mil plastic this helped a little, but it's still cold. So I ordered 23 48"x75" denim hot water heater blankets which I will put up around the walls. Next year we will order more
also denim and do the roof. Today I am hunting down air leaks in the platform with a caulking gun. There is a gap around the bend board that is letting a lot of draft into the yurt. We bought the full insulation package, make sure you get extra insulation though before you put everything else into the yurt. Next year I also will get storm doors. The doors that come with the yurt are nice but they are very cold to the touch.
