Woodland Scenics sells 1’x2’ foam boards in various thicknesses as a part of their Subterrain Lightweight Train Layout System. I was wondering if this is the same kind of foam as the extruded blue or pink insulation foam that many use for layouts and scenery. The blue/pink ones are rather difficult to find around these parts.
Thank you in advance.
It seems to be similar. They claim it does not give off fumes when cut with a hot knife. I have never used it, in that the blue(pink, green, yellow) foam in dumpsters is less money and works better. If you can find it, the green under concrete floor foam carves very nice.
Here, I’ll answer my own question. IF their foam boards–the ones that come in 1x2’ size in various thickness–are made of the same material as their risers and inclines, then they are not made of the extruded foam, but rather, the same kind of styrofoam that electronic goods are packaged in (expanded foam?). I just got yesterday the risers and that’s what I’ve found.
With the proper support I find it dosn’t really matter and as for flamability, the reserch I have done says its about the same.
The WS foam board is styrofoam bead board similar to that in packing materials and styrofoam cups, but perhaps a bit better quality. Go to http://www.woodlandscenics.com/ and from the menu on the left side of the screen, click on Foam System / Foam Products / Foam Sheets or / Profile Boards
Yup, exactly the same as the risers. [:)]
