Is this the right insulation for my heat box?

Insulation from Lowes

Yep thats what I used.  I used the Mossy Oak OSB that Lowes sells for the outside so it looks pretty sweet and it was cheep.   I lined the inside with the same insulation that you have in the picture and with six 100 watt bulbs it got to 190 degrees after and hour and a half.  So it works.  I glued one up the other day and used urac 185.  I unscreewed all but two bulbs and it kept around 95 degrees for 24 hours

I made mine from 1/2" foil backed foam insulation sheets.  I cut 3/4" X 3/4" wood stringers for the corners to screw the insulation to.  Very light weight and easy to move and cheaper since I didn't buy plywood.

I insulated my box with foil backed foan board, the kind in a 4'x8' sheet, similar to Aeronut. His method is about as simple yet effective way to make a hot box.

I used the same stuff.  My 3/8" plywood box would not make enough heat with four 200 watt bulbs to trip the thermostat that Bingham sells.  After lining with the same stuff you used, it makes heat in about 45 minutes.
