Great material for building an outdoor cat shelter

I liked how thick the foam board was. I used it to be a shelter for an outside cat we take care of. I used this inside a plastic tote, along with insulation material and straw. The cat is in the tote all the time now that it's gotten cold.

I need a thick solid material to use for push pins to hold stained glass in place. This material was perfect. I used two prices with tape to protect my table. It held the pins great

Does the job.

Would Recommend

Very stiff. Good insulator. Nice size for small projects. Just wish it was a bit cheaper. Cuts okay with box cutter, but a foam cutter would be cleaner.
