Extruded Polystyrene Foam: Owens Foamular 150 v. DOW Wallmate v. white R-Tech
So I'm foaming at the mouth. (another foam thread) been searching, it can be confusing.
Got some of the white foam at Home Depot.
Its the only thing I can find so far.
Seems usable for my practice diorama, but crumbles easily, kinda chunky surface too?
Searching for the good stuff, if not for this diorama for the somday layout plan.
So far seems like Owens Corning Insular 150 "pink" in 1" is the best choice?
Seems the 150 or 250, either is OK? Or what about R 2,3 ,7 10 etc I'm guesing the higher the R number the denser the foam? Maybe better for details but harder to cut.
I'll just be happy to find any of the pink stuff (ha ha that sounds funny LOL)
The blue DOW stuff seems comparable but has tounge and grove edges I dont think I want.
The white stuff is "expanded" polystyrene not 'extruded', its a big difference in density.
Anyone know were I can find some pink stuff in San Diego county?
I think I may have found a place in Riverside county.
Seems this stuff isnt so popular her in Southern Cal. no basements.
This is why I ask, if I'm going do all this searching and driving I might as well get the best stuff I can but also dont want to break the bank either.
Another question:
Once I shape and glue the foam should I paint it or cover it with plaster of Paris or Hydrocal or mold a scene or...
I'll start "My first practice experimental learning diorama" thread once I download/upload some more pics.
