White or Pink Foam?

[GreenDiesel]

have used bead board (white foam) in the past it isn't as strong as extruded foam (pink or blue) needs more support as said its messy to cut  so instead of gouging out i just brushed lacquer  thinner and Wala you have a hole, depending on the financial aspect it will work the reason I used it  was it was easier and cheaper than extruded and easier to get in 1 and 1/2 inch than the extruded stuff.

Thanks, Jim. I'm using it generally for the same reasons. I had a 4x8' piece which I thought would be perfect to cut down to my 28.5 x 68" size. I could buy (or find) 1-2 small pieces of the extruded foam to build up some hills on the layout. Eventually, I hope to wired up my points (turnouts) -- are there any heat concerns if I run wires through holes in the white foam?
