Each panel probably weighs 8 to 10 pounds! They are just awkward because they are very flexible.
I just finished using my board for second floor bedroom ceiling. It was just ok. Don't be fooled...it is very flimsy and not rigid or hard. I'm not sure what your "torsion box" is in reality....but if it is an insert Inna door...not feeling it's very desirable.
Not sure, I would sand it a bit before i did
No, it will rot with the moisture
A regular staple gun will not penetrate the board, use nails, if using a brad or nail gun it will work
Probably weighs about 7 - 10 pounds....but rather clumsy and awkward to handle.
I actually have the same question. I believe they are getting it from another supplier or they are just making it cheaper now. It does not side across the table saw smoothly anymore. I does cause a problem as I am only 5' 2". But what I use it for I have no other option. I just hope it holds up as well as the old product.
It would depend on how tight the radius(bend) would be. This material is hard and has some flexibility but any sharp turns the board would snap.
As I recall it was a true 1/8"
