The roof glowed some over the stove end of the house.(1000 ft ranch modular home)......but tapered off down the roof line away from the stove..(friend said I needed more insulation,go figure.).Finally today we got some snow and the the place is 5 degree's warmer inside.(4 inches of snow).Nature's insulation cant be underestimated. Other noteworthy thing was my foundation(14 inches exposed above ground) glowed more then the roof...Im definatly gonna Insulate it this summer. Found a product that is a insulating foam with a durable exterior..just have to find a dealer. :roll: Anybody use this product? Pic is my other stove. You can see where the ash can was if you look hard enough,I dont use a vac on this stove , just the shovel and a small trash can.I leave about 2-3 inches of ash on the bottom when cleaning. and no, there is no fluid in the solvent tank in the background..lol http://www.styro.net/FoundationInsulationPanel.htm
