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 Custom Foam Core Signs

"What are the differences between Foam Core Ultra and regular foam core?"

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!

"What kind of signage is Foam Core Ultra most commonly used for?"

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!

"What sizes can I order my Foam Core Ultra Sign in?"

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.

"What kind of image can I use on Foam Core Ultra?"

The sky is the limit! Your graphics can be vector, photographical or both. And your color choices are never-ending! Choose any color in the rainbow for your background, graphics or text.

"Why are regular Foam Core signs such a piece of junk?"

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.

"How many signs do I have to order at once?"

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!

"Is Foam Core Ultra suitable for both indoor and outdoor use?"

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.

"How can I mount or hang my Foam Core Ultra Sign?"

Since Foam Core Ultra is so lightweight, you can easily mount it many different ways. We can fit your sign with a full adhesive back that will stick to virtually any surface!

You can also easily mount your Foam Core Ultra sign using double sided tape, suction cups, Velcro, frames, stakes or grommets.

Or if you'd like to hang your Foam Core Ultra sign from the ceiling, just let us know. We can drill holes in the top of your sign to simplify the hanging process!

"How do I know that my custom Foam Core Ultra sign will turn out the way I want?"

Are you concerned that your custom Foam Core Ultra signs may not turn out the way you want?

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.

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!
