Foamcore Signage

 (also called foam board signage) is a popular option for lightweight, rigid displays used in retail, events, presentations, and décor. Here’s a clear breakdown so you can decide if it fits your needs:

What Foamcore Signage Is

Foamcore consists of a polystyrene foam center sandwiched between smooth paper (or sometimes plastic) surfaces. It’s easy to print on or mount graphics to, making it a go-to for temporary signage.

Common Uses

• Trade shows and event displays
• Retail promotions and point-of-sale signs
• Presentations or school projects
• Directional signage (indoors)
• Photo mounting or art displays

Pros ?

• Lightweight – easy to transport and mount
• Affordable – cheaper than rigid plastics or metal signs
• Smooth surface – great for high-quality printing
• Easy to cut – can be custom-shaped

Cons ?

• Not weatherproof – warps with moisture
• Less durable – dents and bends easily
• Short-term use – best for temporary or indoor applications

Typical Sizes & Thickness

• Thickness: 3/16" (5mm) is standard; 1/2" for sturdier signs
• Sizes:
  • 18" × 24"
  • 24" × 36"
  • Custom cuts available

Mounting Options

• Easel backs (common for tabletop displays)
• Command strips or double-sided tape
• Velcro
• Framing or standoff mounts

Foamcore vs Other Materials

• Foamcore vs PVC (Sintra): Foamcore is lighter and cheaper, but PVC is more durable and weather-resistant
• Foamcore vs Corrugated Plastic: Corrugated is better outdoors
• Foamcore vs Gatorboard: Gatorboard is stronger but more expensive

When to Choose Foamcore

Go with foamcore if you need:

• Short-term indoor signage
• Clean, professional visuals on a budget
• Something lightweight and easy to install
