Apparently Bluecor Fanfold is not normally sold in cooler areas of the country as thicker foams are required for construction in these areas. You can however asked you local Lowes or Home Depot to order it for you and they usually will. Looks like Lowes is calling it something new. Bluelinx
1/4" x 48" x 50' Fanfold Sheathing
Item #: 127129 Model: 669153
You saved me!
The Lowes near me is full of people that have no idea what they are doing or what they sell, going to the store, calling nothing worked they just stared at me blankly or told me to talk to someone else.
I looked this stuff up and its available at the very same store i was at earlier today looking for it. I just bought a bundle online for local pickup at that store in 2 hours, and it better be there! [:@]
The only other people i could find with FFF were Allied, but not the local store..the one 2 hours away..and i wasnt about to make a 4 hour trip without some more research locally...you just saved me 20-25 bucks in gas and half a day
