Nov 28, 2010, 10:10 AM - Huge styrofoam blocks?
Where can I purchase huge blocks of styrofoam in the U.S.?
Something like 4'x4'x8'
I want to do some large scale carving.

Pretty much any hardware store, mind you'd have to stack a few sheets together so the seem-lines could be a problem.

I haven't looked at google yet, but I am not sure if that is something readily available or not. If not what about using multiple sheets of 4'x8' home insulation sheets glued together to reach the desired thickness?
Found this site but they want about $800 for a block the size you are looking for, and that is only for expanded polystyrene...without shipping.
Hope this helps.

I've been looking for the same thing for about a year now. $800 per block (not including shipping) is outta my price range though. I keep thinking of that old show Monster House - they'd get that crap delivered by the truckload and just go to town on them. Was thinking of starting with an Easter Island head for myself. Please keep us updated on here if you have any luck - I'll do the same.

You need to find a local manufacture as you will get charged balloon rate shipping and it will slaughter you... Yellow page searches for sculpting, plastic and foam suppliers in your area... Don't be shy about asking around, like maybe a call to the local community college art department...
Short of that house foam and great stuff from your local hardware store... It works wonderful for an on the cheap build up, and with some selective layering you can actually knock out a lot of the initial shape...
Or if you want a DIY solid block knock together a plywood mold and line it with thin painters plastic sheeting and get yourself several gallons of 2 foam, mix pour and watch your creation come to life...

If you're looking to do it on the cheap, then you can forget about solid foam blocks. $800 per block is the norm.

What about doing a combination? make a mold as Exoray suggested, but use a few of the thick pink foam sheets to take up some space so you don't have to use as much 2-part foam? kind of like a giant multi-layer eva foam ice cream sandwich

Yes and no. There's another thread aroud here where a guy did some large scale foam sculpting, including a mos eisley landspeeder, with layered foam.
The results looked fantastic, don't worry about te layer lines if u bond them together real good and San the final project good with a surface coat of something, you should be great.
The pink/blue foam costs about $20-25/sheet at your local hardware store. It's not a cheap medium, not the bigger you go.
What are you building? What if you made a chickenwire frame covered with papier mâché and a hard shell sealant instead?

I got a few from my professor for a senior project for a sculpting class when I was in college. I don't remember where he got them, but they were free.
But forget trying to sculpt anything out of them, as they make a horrible mess. I gave up on that as a medium and went with something else.

They use those full (4x4x16) EPS billets for large scale civil construction projects, overpasses, etc... always wondered what was done with the left-overs?

Although I havn't seen them used lately, you might try a boat dock manufacturer/dealer/installer in your area. They used to use them as floats, but I think they're mostly rotomolded floats now.
Good luck, let us know if you find it because I've wondered this myself.

I just went through the same search myself in my area. Finally got a couple slabs of extruded foam -- the crunchy stuff -- from the crafts sections at my local Ace hardware and pieced that together.
It was not a happy experience.
I came out of theater, and I got used to having access to great big chunks of white bead foam. In my mind, you start with a great big lump and you carve it down.
But next project, I'm going with pink foam, and will pre-cut and laminate UP. I've seen what a couple of people here have been doing with that, especially combined with CAD and printed templates, and I'm eager to try that instead of continuing the fruitless search for giant chunks of pristine foam.

Anybody else notice the thread was from a year and a half ago?

Yeah, what do people have against old posts, anyway?
That's gorgeous! What's funny is that I just got the urge to add a moai and a tiki to my back yard, and my first instinct was to carve them myself. (Of course, if I actually want to have them, I'd be better off just buying them.)

There are some at The Point at Walden. They were purchased for a dock repair but were not used. Lake Conroe - Montgomery, TX
