EPS Foam?

Hey guys,
Just wondering what EPS foam is?
What is the standard white bead foam we use in Canada for construction?
Where can one get EPS foam?

ok, I guess I jumped the gun on this question. A little bit of research revealed that EPS is 'expanded polystyrene' which I believe to be the white bead insulation foam we use in Canada?
Am I correct? Anybody have any other info?

Plastifab also has a plant in Kitchener, ON. They supply the local Home depot Stores.

If you are intending to cut the foam with a hot wire cutter then the type of white foam you buy is important. There is 'Virgin" foam and "Recycled" foam. Virgin foam is exactly that, made up of all new ingredients. Recycled foam has ground up old foam thrown in. It is perfectly suitable for builders needs but creates problems for us. Recycled foam has hard beads of old stuff in amongst the new stuff. The cutting wire will dwell on the hard beads and create ridges along the cut surface.

For my wing cores I use 1 lb. virgin foam (That is 1 lb/cu.ft), made by plastifab purchased from Home Depot. Some years ago I purchased direct from Plastifab, but I had to buy twelve sheets as a minimum order. It has all been used, Pylon Racing is hard on airplanes!
