The material that we have used (Mike and myself) is called PLAS-TEX Waterproof Wall Panel .060 x 4 x 8 Bright White. I have attached the label on a previous post (Page 2, attachment is called TAG) which you may download to make sure you purchase the correct material. The back side has small dimples in it which is the incorrect side to use. I hope this helps you locate the correct material.
Good luck, Ron
What I found, at both Home Depot and Menards, were two Parkland products - PLAS-TEX NRP and Poly-Wall. Both are described on the Parkland web page at:http://www.parklandplastics.com/residential.htm
The Poly-Wall product is the one with a matte-white side, in bright white color and is .060" in thickness. The PLAS-TEX NRP product has a dimpled (much larger textures than the matte) side, is in pewter white color and is .090" in thickness. Thus what Ron describes above is the Poly-Wall product, according to Parkland's own web page.
The Plas-Tex trademark that is shown on Ron's label is just that, a trademark of the material that was used.
Note that in the third post shown on Page 4 of this thread, Mike Eby states that both he and Ron used the bright white Poly-Wall, as described on the Parkland web page. And the label that was posted on Page 4 is exactly the same as the one found on the Poly-Wall product (I know, because I looked at it and it was an exact match). Mike also states on page 4 that the textured/matte side, not the smooth side, is the side that faces the projector.
Parkland has confused this issue by having both a material trademark and a unique product named "PLAS-TEX." It is understandable that if the Poly-Wall label says "PLAS-TEX" on it, that people will confuse it with the Plas-Tex NRP similar product. Essentially, when one buys the Poly-Wall product, you are getting something made out of Plas-Tex (which is 100% recycled plastic).
Ron is correct in that if someone asks for the Parkland Plas-Tex product that comes in .060" thickness and is bright white in color, that they will get the right thing. Just be careful to not just ask for the Plas-Tex sheet, because that's the official name of the other product.
And, as someone else noted earlier, there is a very good chance that you could find quite similar products, in other regions, from other manufacturers. Look for a white, matte-finish, plastic wall panel to use in laundry rooms or bathrooms. I've seen these walls in pre-manufactured homes on many occasions.
