It's called "GatorBoard", but it is "Expanded Foam" in make-up. (...Don't fret...many people make that slip...)
A word of advice. Unless it's your only choice, Gatorboard carries with it a couple particular risks it's more sturdy Brother Sintra doesn't.
1. It's a much less denser "Foam" subject to Creasing, cracking/breakage if bent past a certain point.
2. It's soft surface is laminated with a Matte White Coated "Paper". It will dent pretty easily, and the dent doesn't pop out because it consists of crushed Foam Cells.
What all this means is that if GB is chosen, you lose a big advantage than many DIY Screens have over their Mfg Cousins (...far removed ...) The surface of virtually every Mfg Screen you can project upon / through is subject to permanent damage.
GB can be repaired...much in the same manner as Drywall can be, but with Sintra, you'd have to try to scratch the surface (...as in displace material, not paint...)
So get Sintra...or any similar Expanded Foam Board that is "NOT" Paper laminated, nor has any tactile surface (ie: smooth is best)
You asked where?
At Plastic Sheeting Supply Outlets.
The two predominant ones are Piedmont Plastics and Laird Plastics. Between them the make sourcing Sintra and other substrates possible in virtually every state. Go to either or both respective Websites and click on "Locations".
Beyond that, if your City / State doesn't have a Branch of either, look instead for Commercial "Sign Shops" in your area as those are the Businesses that draw from the inventory the Plastic Sheeting Supply Houses maintain.
Ask them for Expanded White PVC sheeting in 6mm 4' x 8' or 6mm 5' x 10'. They will know what your talking about, and while they may not carry "Sintra", both they (...and the Supply Houses...) often carry the same stuff only under different names / Mfgs.
