Hi, I'm whipping together a temporary display layout (just an oval,
The display will rest completely on a flat surface, so the foam is only bearing the weight of the layout itself.
Thanks, Chris

Yes. Traveling layouts need extra support. I'd recommend either using a super high quality 1/4" plywood or a decent quality (4-ply) 1/2" ply.

Yes, I would advise that if you are starting with a 1" layer for the base, the plywood will make the layout sturdy enough to carry around. However, if you make the base of 2" or thicker styrofoam, you probably won't need the plywood reinforcement.
I built a 32"x48" display layout on 4" black styrofoam for a base (and "sea level"), and 1" pink foam for the contours. I glued two pieces of
14/" ply 32"x8" crosswise underneath, because the 4" foam was in two pieces, and I didn't trust the glued joint between them. As it turned out, I didn't really need the wood.HTH

Figures. I have 1.5" foam. Right between your recommendations! 3" is probably going to be "un-aesthetic" to the customer (SWMBO).
4"? Black? I've seen thick blocks of white expanded foam (the stuff made of little beads pressed together) used as flotation for cottage docks and I've seen pink, blue and green, but never black. Any idea what it is used for in the real world?Chris
The black stuff comes in 3-1/2" and 4" thicknesses, and is used in the walls between studs. A friend who's in construction gave me cut offs. They also make nice high cliffs. ;-) Up here in the North, we insulate to keep the heat in. Down south, where it gets real hot in summer, it should be used to keep the heat out. But it isn't. Dunno why. Maybe overheated brains don't think straight. ;-)
Is it available with foil facing for radiant transfer resistance (down here we'd put it with the foil facing out)?
Yes, since its job is to reflect infrared. I installed aluminised vapour barrier for this reason. Also messes up radio and TV reception, however. OTOH, it shields over 90% of the wireless network from snooping. You have to be just in correct line with one of two windows to get a signal from it outside the house.
DIY Faraday cage - neat!

AFAIK, the building code up here (Ontario) doesn't require anything to address ir transfer. It does require continuous vapour barrier on the warm side (to keep ice from forming in the walls) and continuous air infiltration barrier (ie Tyvek) on the cold side (to keep the drafts out).
My wireless net is reasonably locked down, but my son's friends frequently use the neighbour's wide open wifi link when they come over to our house (since I won't get them the keys to mine!!!).
