Technical Data
Fire-Rated Wall Assemblies
PermaBase Cement Board has been
tested and/or approved for use in a
variety of fire-rated wall systems.
1-Hour Rating – The 1-hour wall
assembly consists of 3-5/8" steel
studs, 16" o.c., one layer of 1/2"
PermaBase attached horizontally or
vertically with 1-1/4" long cement
board screws 8" o.c. in the field
and perimeter on one side and one
layer of 5/8" Fire-Shield
®
wallboard
attached vertically on opposite side
with joints staggered to those of
opposite side, with 1-1/4" long
drywall screws 8" o.c. in the field
and perimeter with 3" thick mineral
fiber insulation batts in the
stud cavities. UL V452, ITS/WHI
Report No. J99-4001.
2-Hour Fire Rating – The 2-hour
wall assembly consists of 3-5/8"
steel studs, 16" o.c. on one side,
base layer of 1/2" Fire-Shield C
wallboard attached vertically with
1" drywall screws 24" o.c. in the
f
ield and perimeter and face layer of
1/2" PermaBase attached vertically
with 1-5/8" cement board screws,
8" o.c. in the field and perimeter.
Two layers of 1/2" Fire-Shield C
wallboard applied vertically to the
opposite side, base layer attached
with 1" drywall screws 24" o.c. in
the field and perimeter and face
layer attached with 1-5/8" drywall
screws 12" o.c. in the field and
perimeter, with 3" thick mineral
fiber insulation batts in the stud
cavities. All joints staggered
between face and base layer.

Mold Growth on Surface ASTM D 3273* 10
* When tested by an independent laboratory per ASTM D 3273 ("Standard Test Method
for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental
Chamber"), PermaBase achieved a panel score of 10, the highest score possible, indicating
no mold growth under the laboratory test conditions. The use of PermaBase in actual
installations may not produce the same results as were achieved in controlled laboratory
conditions. No material can be considered "mold proof," nor is it certain that any
material will resist mold indefinitely.
