May I fasten a fire rated gypsum board
wall partition with screws instead of nails?
Yes, screws may be used as an alternative
to nails in fire rated assemblies, but must be substituted one
for one with the head diameter and length equal or greater than
required for the nails. Spacing of the screws can be no greater
than that of the nails.
What is the difference between "regular" and "Type
X" gypsum board?
Both regular and Type X gypsum board
are covered under the ASTM C 1396 36, gypsum board standard
specification. Regular gypsum has naturally occurring fire
resistance due to the presence of gypsum in the core. Type
X has special core additives to increase the natural fire
resistance.
What is "Type C" gypsum
board?
"Type C" gypsum board
is a specially formulated gypsum board, meeting all the
requirements of Type X gypsum board, with additional
properties to further enhance the fire resistive characteristics
of the product. |
