They only sell this stuff by the box so I had to purchase 100 square feet of the 8#, 1/2" thick 24"x 50' of this stuff:
Ceramic Fiber Blanket - DS Industries Supplies
It's darn good for the tunnel, insulating the fire wall, etc. as the stuff is good to some 2000 degrees Fahrenheit. It took less than 10 square feet to do my tunnel so I have a lot of this stuff left over. If anyone wants some, I'll sell it by the linear foot (1' x 24" will yield two square feet of course). For those wanting to do their tunnel, I'd make that 5' long to give 10 square feet.
Cost is $1 per square foot plus shipping and will ship from TX, 75070.
