I had never seen that idea before. It looks like it works very well, and give superior R values to your home, and a DIY'er can do it fairly easily too. I like it !
On another note,,,,,,,,,,,Great job Tru, you will be ready for your stove when it arrives in Dec. Let us know how you like it, and how well the heat gets distributed. That was always a problem for me with my Riteway down in the basement. I had a vent to the upstairs right over it, but it was still hard to get the heat distributed through out the house.
Never doubt that a small group of dedicated people can change the world, indeed it is the only thing that ever has.
