Panel Wall - Angle Bracket Mounting on Exterior
Surface
Figure 34.
This shows a typical panel wall installation where the
panel wall thickness is greater than that of the louver.
In this case, it is possible to mount the louver without
flange using angle brackets. The louver could be re-
movable from the exterior of the building.
On many panel wall applications, the panel wall manu-
facturer may accomplish louver mounting by using
various aluminum extrusions to “build-in” the louver
as a permanent part of the panel wall. All panel wall
applications will most likely utilize a full finish collar,
meaning no wall sleeve recess into the wall itself.
(see
CAUTIONS above).
Do not plug the weep holes in the bottom of the louver.
Property damage and poor indoor air quality will result if water
cannot drain to the outside from the weep holes. Appropriate
fasteners must be used to prevent removal by unauthorized
personnel
Angle Bracket Mounting to Exterior Surface
Figure 32.
This shows a typical application where an angle bracket
is affixed to the edges of the louver and then the entire
assembly is mounted from the outside by fastening to
the exterior surface using suitable hardware. This fig-
ure shows an application where the wall sleeve is fully
recessed into the wall and butts up against the louver.
However, the same method of installation may be used
where only partial or no recess is required and a
horizontal air splitter between louver and wall sleeve
must be installed.
Angle Bracket Mounting to Interior Surface
Figure 33.
This is a variation of the installation shown in Figure 32
where the angle brackets are mounted on the inside of
the louver and fastened to the wall from the interior of
the building. This also shows usage of a horizontal air
splitter with a partially recessed wall sleeve. Once the
louver has been installed, run a bead of caulk around
the outside perimeter of the frame to seal it watertight.
Do not use mounting angles or strips at the bottom of the intake
louver that run across the louver's entire length and plug the
weep hole locations. Property damage and poor indoor air
quality will result if water cannot drain to the outside from the
weep holes.
Appropriate fasteners must be used to prevent removal by
unauthorized personnel.
