where can I buy stuff

Hi I am just in the early stages of designing and building my 4th pair of T-lines. I have spent the last three years on the computer making sure I get them exactly right. I am lucky enough to work at a place that has a huge CNC machine to get the cabinets perfectly cut. Anyway, I am wanting to use a combination of acoustastuff and long fibre wool, for the filing. The only problem is that my usual supplier (falcon acoustic) has moved on. Does anyone know where I can get decent long fibre wool in Britain or anywhere for that matter, and that nice thick acoustic foam, the kind that naim use for there driver covers to, well cover the drivers.

cheers for any help.:)
