What is the difference between foam board and PVC foam board?

Foam Board: Foam board is a generic term referring to a lightweight material made from foam core sandwiched between paper or plastic sheets. It is commonly used for mounting artwork, crafting, and signage.

PVC Foam Board: PVC foam board specifically refers to foam boards made from polyvinyl chloride (PVC). These boards are more rigid, durable, and moisture-resistant compared to traditional foam boards. They are commonly used in construction, signage, and other applications requiring a sturdy yet lightweight material.
