I looked into the commercial stuff online before we moved 3 years ago. It was such huge sizes, along with the price for the huge rolls, that I dont use that. We just need 6 pieces 32” x 58” for 3 months.
If I really wanted to advertise that we are deep South rednecks, I would use unpainted plywood.
Hmmm... maybe if I painted some plywood to match the house. lol
There is a local nursery who stocks 2 or 3 widths and will cut it to length for me but is is a little pricey...
