one half inch foam board is sturdier then the standard 3/16th inch foamcore board. But the weight increase is negligible. Made to exacting standards, our foam board is a resilient, polystyrene foamcore board "sandwiched" between paper liners.
The foamcore has a built-in memory, allowing it to return to its original thickness after cutting.
White foam board has smooth, clay-coated, glossy liners.
