Large plastic sheets

Greenhouse supply companies handle the really wide stuff. You might try Farmtek as a start.

How wide do you need? We got some 6 mil black poly sheeting that was 20' x 100' at Lowes for around $80. I'm sure it comes shorter if you don't need 100'. I don't remember the department it was in, but anyone there should be able to point you in the right direction, like they did for us.

Thanks all. I need about 26 wide, will go and do more research at Lowes/HD. Also found a huge number of online suppliers of film and ice rink liners, so will check all that out. thanks again!
