I have 5 rolls of 4' x 50' double bubble radiant barrier. It is NOT like fiberglass insulation. It's very similar to this: http://www.radiantbarrier.com/double-white-insulation.htm I don't know what brand it is. I'm not an expert on installing it, so you'd need to do your own homework to figure out the proper method. It can be cut with a knife or sharp scissors. I bought it for insulating my garage, but after a lengthy layoff, I need the money more than the insulation. $60 per roll. I'm 5 miles West of Greenville, IN, approx. 25 minutes from Louisville. E-mail or call 502-523-4384. I'm on the edge of cell coverage. If I don't answer, please leave a message. Thanks for your interest! Csam kentucky
