Welcome to Librarium Online!
I was wondering what is the type of foam that people use for scenery called? Also I where can I get it? And how much can i expect to pay?
If you can find blue or pink extruded polystyrene foam it aparently shapes very nice and you can detail in a brick pattern with a pencil etc, I use the cheaper white expanded polystyrene foam, cuts with a hacksaw, shapes with a wire brush or sand paper, its just needs a layer of plaster to disguise the foam pattern.
I made my stupidly large crater out of white foam, shaped with an automotive wire brush, plastered over and then PVA + sand to finish.
My fortress is made the same, the brick pattern is easy to carve into the plaster.
I get my foam from the local hardware shop in the house insulation section, $10 gets you a 1.2 x 2.4M x 25mm thick sheet, blue foam is 7 times the price.

Polystyrene? Weird I would've thought polystyrene wouldn't work to well because isn't it made up of those small ball shapes?
Also that fortress is great the plaster makes it look plastic or resin. Wonder why blue foam costs more. Maybe its tougher or insulates better in which case it isn't worth
the extra cash for modelling. Also is there any particular plaster to use or will any sort work?
Edit: Nvm about the balls part just realised what the plasters for. (feel like an idiot now lol!)

The low weight white poly has those balls you can pick out (like in cheap electronics packing) the higher weight is denser and is a lot easier to work with, but any will work well if youre carefull.
I prefer Polyfilla interior powdered plaster, it seems to set harder and so is easier to work with, Selleys No More Cracks works OK.
I use balsa spacers so that the thickness of the plaster can be controlled, PLOg here -> Apoc 40k terrain
Do a small experiment before you try something large!
PS - polyurethane foam is that plastic feeling foam and is not good for terrain IMHO.
Thanks bugbait might have to drop by Clark Rubber and see if they sell polystyrene.
