How to Choose the Best Display Board Material for Your Sign

Just like when choosing the right stock for your business card, you need to consider the purpose of your sign when deciding on which display board material to use.

From Correx to Dibond, each substrate has different properties that can affect your fixture. We’ll take you through the benefits of each and give you some examples of how each can be used. By the end of this blog post, you should know exactly which stock you need for your sign.


Correx is the brand name for a fluted polypropylene plastic board. A sheet consists of a corrugated layer of plastic bound by two flat sheets. The result is a lightweight, economical stock.

The major benefit of Correx is that it is waterproof, making it great for outdoor fixtures. You should note, however, that although Correx is rigid, it can become damaged if exposed to strong winds due to its light weight.

Correx is therefore best for temporary notices such as building site signage, or its most famous use as estate agent signs.



A much more robust alternative to Correx, Dibond is a composite material made of a polyethylene core finished with thin, brushed aluminium sheets on either side. The aluminium is covered in a lacquer that allows it to be printed on.

Still a lightweight material, Dibond has the sturdiness to last as a more permanent fitting outdoors. Thanks to its strength, you can order your Dibond products with drilled holes in each corner. This makes it easier for you to screw or nail your sign up for long-term displays.

Dibond can also be used for stylish indoor signage such as professional door signs. It makes a great alternative to expensive metal or glass signs


Foam PVC

Despite its name, Foam PVC is not a soft, squishy material. In fact, it is more like a solid plastic sheet and it’s made out of compressed PVC foam.

These sheets are strong, durable and super light for their size. They’re also waterproof so can be used outside – just remember that 3mm Foam PVC is recommended to remain inside as it is too flexible to withstand high winds.

Signs made out of Foam PVC are so light that they can be attached to the wall using blu tack or Velcro tape. However, they are sturdy enough that we can drill holes in each corner too, if you’d prefer.


Those are the three main signage materials; Correx, Dibond and Foam PVC. Hopefully now you have a much clearer idea of when you should be using each material. What’s your next signage project? Will you be using one of these display board types?
