I have a new job where i am coming in as the relief pitcher bottom of the 9th, no outs, bases loaded and the star player at bat.
The contractor who was fired as well as the non-licensed architect created a sound wall out of the following materials
-6" bottom and top track
-staggered 4" studs on either side at 16" o.c.
-(2) layers of 5/8" type "x" sheet rock"
they thought that the 2 layers is what gave them the 2 hour rating, i had to explain to them that it is the entire assembly that is rated
I can not find anywhere the ul rating for such a wall that is a min. of two hours
can someone point me in the right direction to find this information?
thank you in advance
