That sucks, I believe there website does say Lowes, HD, and Menards. We have all of those in Des Moines, IA, however only Menards has it that I can see. I can't believe that Parkland can't tell you what stores in what states they use. I think there is another product similar to the Parkland Plastex and the Parkland Durotherm Lite panels, but can't remember the name.
good luck on your searching.
