Martin Cooper Posted June 22, 2011 Share Posted June 22, 2011 I'm a bit worreod by soem of suggestin' polystyrene. I know its cheap, and easy to get. But... highly flammable. Have you seen that 'kin stuff go! You'll fry in there before you had time to get out. Nasty. Almost explosive whne it goes. Use bitumen panels and high density foams made for the job. Suggest: Raid the breakers for automotive grade stuff, fimd a old jag it'll ahve all you need. Quote Link to comment Share on other sites More sharing options...
