John Manville… Go Board. Workers were just bringing some into the building for building a new bathroom. As a construction material it is supposed to take the place of plaster board for wall construction since it will hold the tiles and the tiles will not pull the paper off of it. It is waterproff and can be cut with an Exacto knife.
Ok So much for what they were doing with it.
One look told me, YES! This is PERFECT for building a model railroad. It is only 1/2 inch thick but rigid, light weight, easy to cut, will hold nails and will span your table grid without problem.
If my railroad wasn’t finished, I’d rush out and get some. Availabe at Menards, and probably other big box house stores.
