What Thickness of Foamex Board Do You Need?

Foamex board is one of the most popular materials used for retail displays, exhibition graphics, promotional signage, and outdoor advertising. Due to its rigid structure, the ability for a smooth print finish, and long-lasting performance, many businesses rely on signage like this to convey their message and branding effectively.

With a wide range of Foamex thicknesses and sizes, it’s difficult to understand which option suits your intended purpose. At Carrick Signs, we provide a wide range of custom Foamex boards suitable for every application.

Our following guide will outline the differences between 3mm, 5mm, and 10mm Foamex board printing, including the best uses for each thickness and how to choose the right option for your purposes.

What is Foamex?

Foamex is a strong foamed PVC material commonly used for signage to promote events, retail, commercial, or industrial signage. It’s a popular option for many businesses for long-term, durable indoor and outdoor signage. Foamex is also a stronger and more durable alternative to standard foam board sign materials used for temporary displays.

In comparison to softer foam board sign materials, Foamex provides durability, improved rigidity, and better weather resistance, making it a suitable advertising asset for a wide range of commercial signage projects.

Common applications include:

• Retail signage

• Exhibition and event displays

• Construction site boards

• Wall-mounted branding

• Directional signage

• Promotional displays

• Large-format outdoor advertising

Common Foamex Board Thicknesses Explained

Our Foamex board printing is available in three main thicknesses:

• 3mm Foamex board

• 5mm Foamex board

• 10mm Foamex board

Each thickness offers different benefits depending on how and where the signage will be used.

3mm Foamex Board

3mm Foamex board is the lightest and most cost-effective option. It is ideal for indoor displays, temporary signage, and mounted graphics where the board does not require heavy outdoor weather conditions.

Best uses for 3mm Foamex board:

• Indoor promotional displays

• Exhibition graphics

• Wall-mounted signage

• Retail branding

• Point-of-sale displays

Due to their lightweight composition and simple installation, 3mm Foamex boards are popular for short-term visual campaigns and interior branding.

5mm Foamex Board

5mm Foamex board offers flexibility and durability. It is one of the most commonly used thicknesses for both indoor and outdoor signage applications.

Best uses for 5mm Foamex board:

• Outdoor promotional signage

• Estate agent boards

• Event signage

• Construction signage

• Retail advertising

The additional rigidity helps reduce bending and warping, particularly in larger display formats or outdoor environments.

10mm Foamex Board

10mm Foamex board provides high rigidity and durability. It is ideal for premium signage applications, long-term displays, and larger installations where additional structural strength is required.

Best uses for 10mm Foamex board:

• Large wall-mounted signs

• Outdoor business signage

• High-impact branding displays

• Long-term graphics for exhibition/ trade shows

• Premium retail signage

Because of its thicker structure, 10mm Foamex board provides increased strength and a professional appearance for high-visibility signage projects.

What is the Best Foamex Thickness for Indoor Signage?

For most indoor signage, 3mm or 5mm Foamex boards provide excellent results.

3mm Foamex boards are ideal for:

• Lightweight promotional graphics

• Foam board sign displays

• Exhibition panels

• Temporary interior signage

5mm Foamex boards are better suited for:

• Higher traffic environments

• Larger mounted displays

• Semi-permanent branding

The right thickness depends on the size of the display, mounting method, and expected lifespan. Our boards can also be printed double-sided in high-quality UV-cured inks.

What is the Best Foamex Thickness for Outdoor Signage?

Outdoor signage generally benefits from thicker Foamex board printing to help maintain the stability of the sign.

For outdoor use:

• 5mm Foamex is suitable for many temporary outdoor campaigns

• 10mm Foamex is recommended for larger or longer-term installations

Outdoor durability also depends on:

• installation method

• wind exposure

• sunlight exposure

• board size

For large-format outdoor signage, thicker boards help maintain stability and a professional appearance over time. Our boards can also be printed two-sided in high-quality UV inks.

For short-term outdoor campaigns, some businesses also consider Correx® printing as a lightweight and cost-effective alternative to Foamex. However, Foamex boards generally provide greater rigidity and a more premium finish for semi-permanent signage applications.

How to Choose the Right Foamex Board Thickness For Your Application

The best Foamex board thickness depends on:

• whether the signage will be used indoors or outdoors

• the overall board size

• installation method

• required lifespan

• environmental exposure

As a general guide:

• 3mm Foamex works best for lightweight indoor graphics

• 5mm Foamex suits most standard signage applications

• 10mm Foamex is ideal for premium or large-format signage

Choosing the right signage material is just as important as selecting the correct thickness.
