Mark P Posted February 28, 2008 Report Share Posted February 28, 2008 I ran accross something new - for me - yesterday in the attic of a 1960 home. The sheathing has some sort of paper backing that has fallen off making for oddly ugly attic. Is anyone familiar with this product?

It looks as if they took a bunch of boards and taped them together with kraft paper. I suppose this was some sort of missing link between plywood and shiplap sheathing. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Bill Kibbel Posted February 26, 2010 Report Share Posted February 26, 2010 I have a copy of a mid 1960s ad for Bond-Bord. "It is individual boards bonded together for extra strength and sealed on both sides with 42-lb waterproof building paper". Were they 2' x 16' panels?

barlyhop Posted February 26, 2010 Report Share Posted February 26, 2010 Hmmm, thats interesting, I once inspected an attic where the entire underside resembled thousands of those dangling fly strips in a parchment color. The material was so far gone that there was no evidence of a product name on the sheathing. The ventilation was very poor, explaining the condition but this adds valuable insight if I ever see that again. I presumed it was delaminated plywood at the time but the dimensions of the "Bords" seem to suggest otherwise. Quote Link to comment Share on other sites More sharing options...
Ben H Posted February 26, 2010 Report Share Posted February 26, 2010 So what would you write up on the de-lamintaion of the roof? Quote Link to comment Share on other sites More sharing options...
barlyhop Posted February 27, 2010 Report Share Posted February 27, 2010 This looks more like delamination of a paper covering of the substrate? Does it look structural in nature? I would focus on attic ventilation and/or vapor barrier if I saw this. Perhaps the "paper" covering just dried out at the surface with no consequence.?

Island Ben Posted July 3, 2023 Report Share Posted July 3, 2023 I have a home built in 1966. The roofing material used was indeed Bond Bord. I am having a new metal roof installed. The existing sheathing of Bond Bord is showing signs of the paper delaminating. Should I replace this decking with plywood. There have been spots that have leaked over the years. Also where can I find this ad you mention? Quote Link to comment Share on other sites More sharing options...

The "delaminating" is probably just the paper wrap. Most decking issues are discovered when the existing roof covering is removed, resulting in a panicked call to the lumberyard. Quote Also where can I find this ad you mention? I can't find it now. I've purged most everything that doesn't relate to pre-1940 buildings.
