Hi, Okay I think this is the best solution to the wood paneling on all the 1st floor walls. I'd love to know what any of you have experienced with this kind of "bridging material". As the ground floor walls in this house are 8'4" tall I'm thinking that the right thing to do is buy the widest width roll I can find (so far that's 54") and run it horizontally around the room so that there's only one seam to deal with. Of course there will be vert seams at the windows unless I "cut out" for the opening which I'm inclined NOT to do because in the two front rooms the window set on the front wall takes up most of the wall and that would be a heck of a lot of waste. Thoughts...? Is anybody out there?
