Best place to buy big blocks or sheets of Styrofoam? (EPS)

[Shotzy]

Hey everyone! I'm working on a rather large build and need some advice, I'm searching for the best (or cheapest) place to acquire large blocks of expanded polystyrene foam? I need to carve a large dome shape, I'll probably need around a 2' x 3' x 4' block to start with. Any advice would be great!

You can always glue together eps foam insulation. though I recomend cutting it with conventional tools over hot knives. Can be found at your big hardware store.

These guys sell up 3inch panels of expanded foam. http://woodlandscenics.woodlandscenics.com/show/Item/FOAMSH/page/1

If you look for XPS blocks there are a few sites that show up as well but they don't seem to sell direct via the internet but might be worth sending email.

Awesome, thank you both for the links!

That's the route I'm leaning towards because of how easy sheets are to come by, do you have an adhesive that you'd recommend? I've seen people use expanding foam to adhere EPS blocks together before, maybe that would be the best route to take?
