Introduction
When choosing a sign for your business, the right material is critical to ensuring it is suitable for its intended purpose. In our business, we have often witnessed real horror stories of customers ordering signs that aren’t fit for purpose.
If you’re considering which type of signage material is best for you, you’re likely considering both Aluminium Sign Board and Foamex Signs. Each of these materials is equipped with its unique set of advantages and disadvantages.
Whether you require a temporary indoor sign or a long-term outdoor sign, understanding the key differences between these two materials is crucial to achieving your signage objectives.
This article compares both materials and helps you decide which suits your requirements. We explain both materials and their applications, discussing some key advantages and disadvantages.
What are Foamex Boards?
Fomaex is a lightweight material made from PVC foam board. Although its name suggests foam, its structure is not foamy. Foamex sign printing boasts durability and rigidity and has a super-smooth surface that facilitates stunning print quality.
It is commonly used for medium—to long-term application requirements. It can be used indoors and outdoors, offering short—to medium-term protection against rain, UV, and general wear and tear.
Frequently used by businesses needing a flexible signage solution for events, advertising boards or displays, this material provides an elegant and eye-catching finish without breaking the bank.

What is an Aluminium Sign Board?
Aluminium Composite is a durable material made from two aluminium sheets that sandwich a Polyethylene core. It is well known for its robust and weatherproof features and is used extensively in harsh working environments, such as construction, manufacturing, and engineering.
Aluminium Sign Board’s core strength is its unrivalled toughness. It offers long-term protection against rain, UV, chemicals and general wear and tear. It can be placed in wet outdoor environments for 5-10 years without losing its print vibrancy. Although made using aluminium, it is exceptionally lightweight thanks to its soft core, which allows for a stress-free installation.

Foamex Sign Printing Disadvantages
Despite its extensive list of benefits, like all things in life, Foamex has disadvantages. These are –
Limited Outdoor Lifespan: Although Foamex Signs can undoubtedly be used outdoors, they do not offer the same long-term resistance to the elements as Aluminium Sign Board.
Warping Risk: Foamex is susceptible to warping, especially with thinner thicknesses such as 3mm or 5mm. To reduce the risk, try to keep it away from high temperatures.
Durability: Although it can hold its own, it’s nowhere near as tough as Aluminium Sign Board.

Aluminium Sign Board Printing Advantages
Now, let’s move on to Aluminium Composite. Here’s a few key reasons why this signage material is extremely popular –
Unrivalled durability: Aluminium Composite is undeniably your best option if you’re after a durable sign. Offering long-term protection against whatever the elements throw its way.

Aluminium Composite vs Foamex – Which One is Best?
Now for the big question. Which sign is best, Foamex or Aluminium Composite?
Well, when it comes to signage, there are no absolutes. Instead, the best sign for you depends upon how your sign will be applied.
