What Thickness to choose for Foam PVC Boards: 3mm, 5mm, or 10mm?

Foam PVC board is widely used across many industries, such as advertising and signage, construction, interior design, and in DIY projects. Foam PVC, referred to as PVC or Foamex, is highly regarded for its light weight, durable nature, and ease of use, making it popular amongst professionals and hobbyists.

One of the most common questions that come up is:
 “What thickness of foam PVC board should I choose, 3mm, 5mm or 10 mm?”

In this particular case, the answer varies based on how one intends to use the material. In this guide, we will discuss the advantages and common uses of each thickness to help users reach a decision that best fits their project requirements.

What is PVC Foam Board?

Foam PVC board is made of expanded polyvinyl chloride. They provide a sturdy, yet lightweight solution for both indoor and outdoor applications. Although referred to as “foam,” they are rigid and smooth, which makes them ideal to be printed on, mounted and used for crafting.

Foam PVC boards come with multiple benefits:

• Convenient to transport as they are lightweight.
• Protecting your material from the elements, such as rain, is not going to damage the board.
• They are safe from chemicals.
• Depending on the grade, the board can be flame-retardant.
• They can be easily drilled and shaped.
• They can be of different colours and textures.

Wholesale POS provides a variety of foam PVC sheets and also stocks the commonly used 3mm, 5mm and 10mm sheets.

Why Does Thickness Matter?

The choice of thickness determines how long the board lasts, how flexible it is, how much weight it carries, how it looks, and its price. Thicker options provide more rigidity, while thinner ones will be more flexible and affordable.

• The application could be indoors or outdoors (temporary or permanent)
• Installation type (attached to a wall, self-standing, suspended)
• Stiffness needed (will it hold its shape or will it be able to bend?)
• Expenditure available (economy variant increases the budget).
• Willingness to move it (some boards are heavier than others).

Let’s break down how each common thickness — 3mm, 5mm, and 10mm — performs.
