- Install 2" H-stud into C-runner at foundation and over
edge of liner panels. H-stud may be screw-attached to C-runner with 7 x 7/16" pan
head screws on alternate sides at bottom or top of partition to hold components together
while erecting.
- Continue installing liner panels and 2" H-studs until
desired wall length is achieved.
- Insert 2" C-runner over edges of final liner panels.
- Install C-runner over tops of H-studs and liner panels.
Attach vertical and horizontal C-runners together at intersecting corners with one 7 x
7/16" pan head screw each side.
- Plumb the area separation wall and temporarily brace.
- Attach H-studs to wood or steel framing of the structure at
intermediate floor level with aluminum breakaway clips attached to both sides of the
H-stud. Use two 7 x 7/16" pan head screws to attach the aluminum clip to the H-stud
and one 1" Type W screw to attach the aluminum clip to the wood framing.
- Upper level installation begins by installing an inverted
C-runner to the top of the area separation wall and attaching it to the top C-runner with
two 7 x 7/16" pan head or hex head screws at 24" o.c. Once the C-rubber is in
place steps 2 thru 9 are repeated.
- Area separation walls may be stacked to a height of
44'0". Heights over 23'0" require that additional aluminum breakaway clips be
installed at midspan of wall panels at each H-stud on both sides of the wall.

TEST DATA
UNIMAST Area Separation Wall Framing has
been tested at Warnock Hersey/Inchscape Testing Services in accordance with ASTM E-119 and
achieved a 2-hour fire resistance rating. The ASTM E-119 test was conducted by applying an
axial load to the area separation wall framing to simulate a stacked wall height of
44'0", exhibiting the structural adequacy of the framing.
PERFORMANCE EVALUATED
Fire test results show that the UNIMAST
Area Separation Wall System meets code requirements. For more information about the
evaluation of the system's performance, contact your UNIMAST sales office. |
