Union Premium Foam Board 20 x 30 x 3/16" 10-Pack : Matte Finish High-Density Professional Use, Perfect for Presentations, Signboards, Arts and Crafts, Framing, Display (White, 20x30)

I’m surprised with the quality and this is what I’m looking for for my special event demonstration!

I’m using these foam boards for wedding events. Going to print posters for $20 and then glue onto foam board. Saves about $50 each.

3 out of ten pieces of foamboard were damaged

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!

I used these boards as the backing for sound-deadening foam in my home studio. Spray adhesive holds the foam squares securely and the 24x36 inch boards were secured in place with small finishing nails and double sided tape. Lightweight, clean edges, and perfect size.

Purchased to use at work to mount campus maps onto. Good thick foam board, edges bend easily.

Used to temporarily cover windows until blinds could be installed

Glued posters to 15 of these for a community production of Gypsy. Worked great!
