When a print needs to stand rigid — a display sign, a presentation board, a directional sign — it gets mounted on a rigid board. The two most common are foamboard and PVC board, and they suit different jobs: one is light and inexpensive for indoor display, the other is tougher and weather-resistant for harder use. Choosing wrong means a warped indoor board or an overpriced one. This guide settles it. It is part of our complete posters & mounting guide.

A foamboard display sign

Foamboard — light, rigid, indoor

Foamboard is a lightweight board: a foam core sandwiched between paper or card. Its strengths:

  • Very light — easy to handle, hang and transport.
  • Rigid and flat — holds a print perfectly flat for a clean display.
  • Inexpensive — the budget choice for indoor mounted prints.

A foamboard mounting is the go-to for indoor displays, presentation boards, directional signs and point-of-sale. The catch: it is not for outdoors or wet conditions — moisture warps it and the edges can dent. Sizes like A1 foamboard are common for display.

PVC board — tougher, weather-resistant

PVC board (including hollow/corrugated PVC boards) is a sturdier, plastic-based rigid sheet. Its strengths:

  • Weather-resistant — handles moisture and semi-outdoor use where foamboard fails.
  • More durable — stands up to handling and the occasional knock.
  • Reusable — survives repeated display use better.

A hollow board is the choice for tougher indoor use, semi-outdoor signs and anything that needs to last or get handled. It costs more than foamboard, but it goes where foamboard cannot.

How to choose

  • Indoor display, light, on a budget → foamboard.
  • Semi-outdoor or wet conditions → PVC board.
  • Needs to be handled or reused a lot → PVC board.
  • A premium decorative wall piece → consider canvas instead of a mounted board.

The rule: foamboard for light, indoor, cost-sensitive display; PVC board when it must survive weather, handling or repeated use.

Finishing and display

Whichever board, mounting a print well makes the display:

  • Mount the print flat with no bubbles for a clean look.
  • A laminate protects the print surface on handled or semi-outdoor boards.
  • Stands and easels turn a board into a free-standing display; foamboard on a stand is a common directional or POS setup.

Frequently asked questions

Foamboard or PVC board — which is better? Neither — foamboard is light and cheap for indoor display; PVC board is tougher and weather-resistant for semi-outdoor or heavy use. Choose by where it lives.

Can foamboard go outdoors? No — moisture warps foamboard and dents its edges. Use a PVC board for semi-outdoor or wet conditions.

Which is cheaper? Foamboard — it is the budget rigid mount for indoor display; PVC board costs more but lasts in tougher conditions.

What's a hollow board? A corrugated PVC rigid board — sturdier and more weather-resistant than foamboard, good for semi-outdoor and reusable signs. See the mounting range.
