If you want to buy a roll I can give you the details of the company ( in China) I got mine from, the best info though is from Parabeam in the Netherlands, who invented it. Freight was a lot from Europe so we didn't go with them. Price for us was about NZ$30 per metre including freight but it's a 1.5 metre wide roll and only one layer per side is used so for example it's enough for 20 eight footers ay NZ$80 per board. http://parabeam.nl/ [video=youtube;FSAgsiFp_G4]https://www.youtube.com/watch?v=FSAgsiFp_G4[/video]
