That is so interesting! I think I might give this a try.. errr ummm, I mean make my husband give this a try! Lol! Very timely too as we have some deadly cold approaching next week (10-15 degree nights) so thank you for posting! :)

Great video.
I've used the foam insulation by itself before. It's not effective and still lost a fair amount of the wrapped branches.
Adding the heater, the blanket, the tarp and the bucket makes a huge difference.
