I talked to Angie at Parkland Plastic about the availability of this PLAS-TEX material we are using for HD screens in your area. The problem that some of you are having in locating this material is that Parkland only distributes this material in the Midwest, so all of you that are located in the east, west, and south will probably not be able to find it at your local home improvement store.
They will ship it direct to you from the factory. Shipping cost is about $10.00 plus packaging (about $5.00). Your total cost, including the material, is about 25 to 30 dollars. Call Parkland Plastic (1-800-835-4110); ask for Angie - she knows exactly what you want.
I have some dorp-off pieces left for which I would be glad to mail you a small sample. RAGEYER@aol.com
Also attached is a drawing of how I measured and cut the material to the maximum size for a 4 x 8 sheet. (see - screendwg.jpg)
