Understanding Foam Board

If you’re new to the foam board world, it’s not just the stuff you see in art classes. Foam board, often made from a polystyrene core, is used in everything from crafts to construction. It comes in various types, each suited for different jobs.

Types of Foam Board

  1. Polystyrene Foam Board: The most common type. It’s lightweight and great for insulative properties.
