Question
What is foam core and how thick is it?
Answer
Foam core is a lightweight display board: a polystyrene foam center sandwiched between two smooth paper facings.
| Thickness | Best for |
|---|---|
| 3/16 inch | Standard signs, presentation boards, and mounted prints |
| 1/2 inch | Larger displays that need extra rigidity |
- Light enough to hang or prop on an easel, stiff enough to stay flat
- Smooth facings take crisp, full-color printing
- Best kept indoors, since it can warp in heat and humidity
