I use a reflective radiant heat barrier insulation. It has two layers of Aluminum with plastic bubble insulation in between.www.lowefeflectiveinsulation.com is the link. It can burn leaves that sit against it too long. It bonces light all over the box, one reason my 400w work better than it should, I live at 5,000ft and have over 30 degree temp. changes everyday, so need some insulation. I learn to get them big from the people around here, of course 12/12 are supposed to be smaller...rw
