Jack. To get your aluminum sheeting up. I used a 2' by 2' piece of plywood with a1' 2x4 centered on end to the plywood. then a floor to raise the plywood. The aluminum centered itself nicely. Then heled the sheet in place with some 1.75" wood screws with large fender washers. Then a sheet of 1/8th aluminum, 2' by 4'. Screwed the panel to the floor with 6 - 3/4" spacers to make an air gap between the floor, and heat shield. Bob Dunahugh
