Union Premium Foam Board Black/White 30 x 40 x 3/16" 10-Pack : Matte Finish High-Density Professional Use, for Presentations, Signboards, Arts and Crafts, Display (Black/White, 30x40)

Nice sturdy foam board for signs. Arrived in excellent condition.

Foam core itself is typical and exactly as expected but the folder box package is not cheap / is good to use for storage or reuse.

Some of the boards were a little dented on the corners, but it still worked perfect for picture boards.

I've done a TON of model building with foamcore over the years and was really loyal to Elmer's foamcore. But since the prices have gone WAY up for those, I figured I may as well try this brand I'd never heard of. I have to say that so far, I'm pretty satisfied with them. They don't seem to be warped any more than Elmer's would be and I've noticed no problems with the quality of the boards.

I use these for an entirely different purpose. In the winter, I place behind the sofa and the wall and against other cold walls to keep the house more confortable.

The media could not be loaded. The foam core boards arrived fairly flat. I generally chose the side that was curving downward rather than upward to glue the purple &black acoustic foam squares to the black foam core board. Oddly, they radically curve in the opposite direction after the spray glue dries. I don't fault the foam core boards for that. I believe when the glue sets it shrinks causing the boards to curve. They are plenty rigid, and to fix the problem I actually just ever so slightly creased the boards at the 1/3's and they lay perfectly flat on my walls now. I'm glad I got black boards as they basically disappear when they stick out from around the acoustic squares. It can be easily trimmed and I did that on some of my panels. Just use a sharp utility style knife and be careful to have a solid straight line to guide the cut or you will easily run amok! LOL no matter how careful, be sure to put a protective layer between the cutting and your floor. It is easy to accidentally scar the floor cutting through these boards!

When I ordered this I was worried about shipping damage. When I received the box I was Extremely Pleased with how it was packaged, Perfect Condition, Absolutely NO damage to the foam boards.

I used these boards to make two large V-flats for my home studio. They worked great, and I have no complaints. Get some 2" gaffer paint in both black and white, and you can easily make them for a fraction of the price to buy them.
