[RCSE] Source of Foam

[Dan Ahearn]

A few years ago the company I was with built a refrigerated warehouse. In the deep freeze section they literally used a truckload of 2 inch think high density Dupont blue foam to cover nearly a 1/4 acre in the floor. It was .   I'll bet they didn't get that stuff from CST at   Were can I find that stuff?  Building supply maybe?   Seems like I might be able to get a better price then 3 to 5 bucks a square foot to learn how to cut foam with.   Everything at home depot and lowes is like 3/8 in thick.   Any ideas?   Dan in Dallas .....
