I bought mime from the US when I was building my planes last year(from PLProd), pretty lite but the price was pretty high, of course it would depend on what plane you are building, mine require a false floor/two fuel tank bulkhead/firewall/and a bulkhead way back in the tail which I all did with the stuff.

The longest I could fine was 24", I required 36" for the pipe tunnel so I just laminated two pieces together with a light ply in between seem pretty solid so far.
