Gilly Posted July 13, 2007 Share Posted July 13, 2007 I've done the good old search, and dragged up a thread from around 3 years ago which came to no conclusion on this, so I'm hoping this might be more successful. I'm looking for flame retardent polystyrene blocks to carve and skrim. Aproximately 2000mm x 1500mm x 300mm. Does anyone know of any decent suppliers? Thanks!

Brian Posted July 13, 2007 Share Posted July 13, 2007 You could use ordinary polystyrene and cover it in Rosco Foamcoat which is a) a flame retardant and b) a protective coating a bit like plaster. Link to comment Share on other sites More sharing options...
Gilly Posted July 13, 2007 Author Share Posted July 13, 2007 Good call! Do you know where I can get any non-flame retardant polysyrene of the appropriate dimensions (above)? Link to comment Share on other sites More sharing options...
Brian Posted July 13, 2007 Share Posted July 13, 2007 Thinner bits glued together with Rosco Flexbond? Hmmm, starting to sound like a Rosco ad.... [EDIT]Just spotted that Flints do FR polystyrene 2440 x 1220 x 50mm so 6 sheets glued together will do it. Link to comment Share on other sites More sharing options...
AndrewGrant Posted July 13, 2007 Share Posted July 13, 2007 I had to build a polystyrene and steel deck mountain recently. We bought 7 blocks of poly which were 8'x4' by 2' depth from Fast Shield in London. They were good and fully flame retardent. Site is http://www.fastshield.com/ To carve this to the correct size we hired a hot wire cutter from Flints. HTH! Andrew Link to comment Share on other sites More sharing options...
Tomo Posted July 13, 2007 Share Posted July 13, 2007 When it comes to carving, you really do need a hot knife or hot wire cutter. Sharp blades really don't work too well - you tend to 'tear' the PS which leaves a poor finish for your final coating. Link to comment Share on other sites More sharing options...
Jivemaster Posted July 13, 2007 Share Posted July 13, 2007 Ordinary PS sheet comes from builders' merchants as they use in in floor rafts. It is never truly fire retardant. just when plastered it is hard to ignite Link to comment Share on other sites More sharing options...
Psychedelic Theatre Posted July 14, 2007 Share Posted July 14, 2007 I don't have any experience with EPS. But when you cut a piece of fire retardant EPS, is the surface that you have cut still fire retardant? Link to comment Share on other sites More sharing options...
