What You Should Know About Custom Foam Core Ultra Signs

You may think you're familiar with this material, but you're not. That's because Foam Core Ultra is a unique material exclusive to TheSignChef.

Regular foam core, commonly used in school presentations, is comprised of a foam interior covered with a smooth paper coating. You're probably asking yourself, "Why would I ever want a paper sign?" You wouldn't! That's why here at TheSignChef, we only offer Foam Core Ultra custom signs.

While regular foam core signs are delicate and easily susceptible to damage, Foam Core Ultra is much more resistant to scratches and indentations and banged-up corners. Foam Core Ultra is still lightweight and economically priced, (in fact, Foam Core Ultra costs no more than regular foam core!) and it's also completely waterproof and durable enough for handling and transportation. Foam Core Ultra is a popular sign material for corporate and sales presentations, mission statements for office lobbies, tradeshows and mounting posters.

Frequently Asked Questions about Foam Core

Let me tell you why!


Many people choose Foam Core for their custom signage because it is lightweight, rigid and economically priced. But what they don't know is how sensitive to damage the material really is.

Foam Core is 3/16" thick foam with a smooth paper coat on both sides. This material…

  • takes almost no effort to damage
  • is prone to surface imperfections and indentations
  • is easily scratched and bent up …compresses but does not spring back into place
  • and any amount of moisture will cause irreversible damage!

In short, after very little handling, your Foam Core sign will begin to look unprofessional.

Introducing Foam Core Ultra!

Here at TheSignChef, we prefer a little something called Foam Core Ultra. This is a completely different product than Foam Core, but has all of its good ingredients and none of the bad. Foam Core Ultra is 3/16" thick foam, and is coated on both sides in perfectly smooth plastic, rather than paper.

Foam Core Ultra is as lightweight as Foam Core but far more rigid. It is more dent resistant than Foam Core and is completely waterproof. So Foam Core Ultra is better for signs that are handled and transported repeatedly.

Foam Core Ultra Signs are perfect for indoor use. Outdoor use is also okay in short spurts, but we do not recommend using Foam Core Ultra for long-term, outdoor signs.
Are you concerned that your custom Foam Core Ultra signs may not turn out the way you want? After all, we are probably hundreds of miles away from you, so how can you be certain your order will turn out right? Fortunately, it only takes seconds to transmit full-color custom Foam Core sign designs from our computer to yours because e-mails travel so fast these days. Upon order approval, here’s how the process works: First, your order goes straight to our Art Department Our graphic designer will then e-mail you a proof (a “proof” is a picture of what your sign will look like) Once you review the layout, let us know if you would like to see any changes, and … If you have any changes, we will e-mail you proofs as needed until you’re completely happy with your design.
Unusual signs and large order requests usually dispatch within 3-7 normal business days. If your order is time sensitive, please confirm the particular turnaround time with Customer Service at 1-800-899-6272.
Definitely! You can get virtually any design or color scheme you choose on the custom foam core sign.
Absolutely! The more custom foam core signs you receive, the less each of them will cost. Consequently your custom foam core signs can reach an increased number of people for a more cost-efficient price!

The main difference between these two materials is that regular foam core has a cardboard coating on both sides of its interior foam, whereas Foam Core Ultra is coated with plastic.

Both materials are lightweight, fairly rigid and are used for the same types of signage.

But you will run into the following problems with regular foam core:

  • The material is sensitive to damage
  • Its paper coating is prone to surface imperfections and indentations
  • It is easily scratched up and bent
  • It compresses but does not spring back into place
  • Any amount of moisture will cause permanent damage Even minimal handling can cause damage


Alternatively, with our Foam Core Ultra, you won't need to worry about any of those problems. Foam Core Ultra is plastic coated, durable, waterproof, scratch and dent resistant.

Foam Core Ultra has everything you were looking for in a foam core sign, only more!

Your Foam Core Ultra sign can be any size you want! Unlike most companies, we don't put a limit on the size of your signage. Our largest single, seamless piece of Foam Core Ultra is 4'x8', but we can put multiple panels together to create a sign as large as you want.
The choice is yours! We are capable of handling any project of any size. You can order one or thousands of Foam Core Ultra Signs at once!

Although custom foam core signs are sold by other sign companies, we're not a big fan of utilizing PVC Plastic Sign material outdoors. PVC Plastic Signs are sensitive to solar heat which might cause the plastic sign material to warp. Plus, there's virtually no price savings above the predictable qualities of aluminum.

Manufacturing defects fit into our Workmanship Guarantee, therefore we will replace your sign for free.

Foam Core Ultra is intended for inside use and temporary outdoor use. It is not recommended for long-term outdoor purposes. As such, Foam Core Ultra is ideal for use in schools, corporate and sales presentations, point-of-purchase signage, tradeshow signs, mounting posters and mission statements in office lobbies. But go ahead and use your imagination — the possibilities are endless!
