The southern parts of the US generally. Places were it does not get
cold enough most of the time for people to worry about stuff freezing in
basements. The blue/pink foamboard is *commonly* used up here in New
England as insulation on the outside of poured concrete
basements/foundations. One can just stick it on and back fill against

When I lived in the Dallas area, I did some searching and
found several HVAC contractors that were listed with 3M as
dealers. Home Despot will order it if they don't stock it
in the local store. They stock it in St Louis @
This a response to several specific posts but I also thank all others

Well, you've got me there: the weight of plywood would indeed defeat the
benefit of a light weight foam-only base. From that angle it might be
better to glue the road bed and track to plywood -except I like the
thought of how easy it would be to poke holes in the foam to glue in
trees and possibly carve a creek bed in. I'll have to take this into
consideration but I doubt I'll go 'old school' with the hills and such.
I think at least in that area I could get away with white foam.
Good idea. I hadn't thought about special orders. I checked this out
yesterday at both Home Depot and Lowes. Results are sketchy: both places
said that they can't get anything from warehouses from central or
eastern states. Depot didn't seem to be interested in the thought of
only buying one or two sheets. Lowes was more helpful but I'll have to
check in during a weekday (I guess the person who does this type of
special order is off weekends) to know if a warehouse in northern CA
might have it and what a minimum purchase would be. So, I'll know
something this week.
Lol! If you've enough good stories you could probably write a book and
make a nice profit. Vintage or traditional Halloween is growing in
popularity and lots of folks enjoy hearing about how it used to be. It's
sort of a backlash to the look of so much of modern Halloween which
tends to either be too cutesy or all blood and gore with some demonic
imagery mixed in. I'm in my 40's now and can see how much better the
holiday was when I was a kid.
Thanks. If I end up using bead board I plan to experiment with a piece
before actually using any for the layout. Different cutting methods and
such. What sticks to it and what doesn't. I did find a piece that came
in a shipping box at work and tested it for fire resistance. Using a
micro torch I couldn't get it to catch fire. Interestingly, the fire
applied gently causes it, not to melt, burn or turn black, but to shrink
away. I'll need a bigger piece to test further but it looks like with a
little practice that rocky hillsides could be formed, even shallow caves
and overhangs just by sculpting with such a small flame source (and no
mess like filing creates).

Yep...really good for that. Also used in many commercial jobs between
the masonry and exterior walls......and used for insulation under
siding over the exterior sheathing , usually 1", under siding ,
exterior of commercial building under the pre-cast panels, under
floors both concrete and wood. I have seen it ,
although I wouldn't do it , as the only sheathing on exterior walls of
residential jobs. Usually 1" and then the vinly siding goes right over
that. Not very much strength there , most of the strength is now in
the drywall. The vinyl siding just hangs there and does nothing.
It is available in the south but it's not near as prevelant on the
west coast. I don't know why since they need to insulate for AC.
They use a lot of insulation out there called R Tek
Why am I going on like this.....this is a train group , not a
construction forum ?
My wife had me locked in the cellar all day :-(...and I needed someone
to talk to. I stayed up too late last night playing with my Big Boy
and she was upset.
Try looking in the yellow pages for insulation contractors...."cold
storage" or "low temp".
For the most part they will have tons of scraps on jobsites that you
can have for free.
Dow's blue board that is thick enough to build a layout on is usually
called SE ( square edged) or SM ( smooth material) and comes in 2'x8'
sheets( some plants are putting out 4 x 8 sheets, but not all) from
1/2 inch think up to 3" thickness.
I can't remember the PSI of the SE but is was higher than the material
used in homesites.
The best of the best is the grey board by Dow that is used in cold
storage warehouses and depending on the floor load and how high they
going to build pallet racks will determine whick PSI greyboard the
< scratching head and trying to remember>
SE blueboard is 30 psi
HL 60 is 60 PSI
HL 120 is 120 psi
They might have different types out now but when I was involved in cold
storage design those were the most common psi's.
Again, look for low temp or cold storage contractors or "industrial"
insulation suppliers in the yelloow pages.
While you're there check to see if they have hydrocal.....our "cost" on
it was usually about 6 bucks for 80 lbs sack of B-11. It's used for
making insulated fittings for industrial insulation on pipes usually in
petro chemical plants. The B-11 is mixed and used as a glue to bind
the pieces together to make the fittings.
Hope this helps

I'm in the process of landscaping my layout now. I used 1x3's for the
table frame, 3/8" plywood on top and then 1" white styrofoam on top of
that. Though it is messy to cut(I have no hotwire), it's excellent for
applying scenery, building up mountains, cliffs...etc. Any glue will
stick to it( that i've tried). I mostly use Elmers and Hobetac.
Acrylic paint will be fine but i'd avoid latex base, it will peel.
For building mountains or hills, break pieces to shape, pad with some
newspaper or cardboard strips and then hit it with plaster clothe.
Sounds cool! I've tried some more sources and that extruded foam stuff
just isn't used around here. The one home building site I found was
using the white foam and the guy at Lowes said he'd been in the area for
20 years and never got a request to order any of it. So, good or bad, it
looks like I'll be trying the white board. I think I'm actually looking
forward to the challenge of using something a bit more unusual to work
with (for some reason). And thank you especially for the acrylic good,
latex bad note. There's a pitfall I can avoid. :)
I bought a small piece today to pin flex track on and check different
radiuses and curves. I know I can get away with 6-8" with the On30 0-4-0
and stubby car kits (like Boulder Valley & International Hobby makes)
but will check with some old HO standard boxcars hooked up to see what
happens. Forward and reverse. Full speed. See what it can take.
If you come across anything interesting while working with the white
board, please let me know. Have you tried a mini torch for forming
shapes into the foam? I've only tested it on some really cheap foam used
as packing blocks in a shipping box but it seemed to work nice without
burning the surface. And no mess. If you try it, have an extinguisher or
something close by just in case as I've only tested on a small area so
This maybe a dumb question...Did you check your local mom & pop
hardware store? Even if they don't stock it, they can probably add it
to an order from one of their suppliers. You may have to wait a short
while until they get an order to justify shipping. Also check your
area lumberyards and concrete suppliers...more and more foam is used
for foundations and as a light weight filler. I check with my sources
frequently to purchase at a reduced price sheets that were damaged.
Usually anything less than a half sheet doesn't sell, I get it for
cents on the dollar...I break or cut them up anyway, so why not save a
few bucks in the process. Also check with manufacturers in your area,
sometimes they receive shipments that are packed with insulation
foamboard to prevent damage in shipping. Doors and window contractors
are a good source for foam used as packing material. I've also scored
some great deals at a distributor where I get my 4x8 sheets of styrene.
It comes sandwiched between sheets of foam to them, cheaper than
plywood and lighter. Just a thought.
