Good video. That would work. How could your stove not be burning? Try more pre-heat. Use the bottom of a peanut can as a preheat dish. Pour some fuel in the stove - spill some on the dish - light. The only drawback to that design that I have found is if your pot overboils (like with macaroni noodles) or if you spill water on top of it - once water gets in it there can be problems, but otherwise they work good. Attic insulation is the right stuff in most cases - what color was it? Post a video of your efforts and let the experts evaluate.
