Keeping warm in a harsh, snowy winter

[HawaiiYurts]

The Nasa developed insulation isn't ideal for R-value (meaning keeping the heat in long-term). It's great at reflecting heat, but without a heat source, it will quickly cool down. In the Alpine Yurt I mentioned above, they provide a totally different insulation made out of recycled blue jean material. Still trimmed out nice, but it's much thicker and gives a higher R-value insulation. You could double up and keep the astrofoil insulation but back it with the other kind...

Glad you figured out some kind of fix though! Brrr... I may live in Hawaii but my roots are from Maine
