Re: OSB Sheathing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Based on the tables I have, 1/2" plywood weighs 1.5 lbs/square foot (I have
had this chart for so long, I don't know the source).

For 1/2" OSB at 53 lbs/sheet, this comes to 1.66 lbs./square foot or about
10% greater.

Do you agree with this in general? It kind of makes sense with the glue,
chips, etc.

Regards,
Bill Allen
