Is foam board and pvc board the same thing?

No, foam board is also called foam board or insulation board. The main raw material is polystyrene resin, which is made by foaming process. Foam board has excellent thermal insulation, fire prevention, waterproof, impact resistance and other properties, and is widely used in construction, decoration, packaging, thermal insulation and other fields.
