Author 1 hour rated acoustic ceiling
Compute

I am looking for a UL design for a 1 hour fire rated acoustic ceiling. The
ceiling will not be exposed.
The ceiling will be a minimum of 6 feet from the concrete deck above. The
concrete slab above is
10" thick. The ceiling will be approximately 9' above finished floor. I am
specifically looking
for a UL design number.
