General Louver Installation Instructions
Installation Instructions
1. Locate all crates, boxes, cartons, etc.
2. Use care when handling louver sections to prevent damage. Louvers are to be carefully lifted by the louver
frame or supports. Use multiple lifting points when possible to avoid deformation or distortion of louver
components. DO NOT LIFT LOUVERS BY THE LOUVER BLADES. Use appropriate caution to prevent
damage to the louver finish.
3. Remove louvers and any provided accessories from the packaging and inspect for damages. Verify louver
dimensions and that all required pieces are present.
4. Single section louvers will ship fully assembled. Multiple section assemblies will ship as individual louver
sections to be combined into the larger assembly at installation. Large multiple section louver assemblies may
ship in multiple crates.
5. All louver sections will have a factory applied louver label affixed. This label will identify the louver size and a Tag
identification if one was provided during the order process.
6. Verify that all required installation hardware is available, to include mounting angles and fasteners (customer
provided or optional manufacturer provided). Inspect the opening for any damage or issues that may affect
installation of the louvers. Remove any obstructions or debris as required. Adequate substrate depth must be
verified.
7. Check the dimensions of the opening to verify the louver will fit correctly. Check the opening is square and
plumb.

1. Locate the optional extended sill, if provided, and
place in the opening. (Extended Sill Details)
2. Locate mounting angles and fasteners required to
attach the louver to the structure. Clip angles and
fasteners are by others unless the optional mounting
angles have been ordered from manufacturer with
the louvers. Anchors to the structure are by others
and are not manufacturer provided.
(Mounting Clip Details)
3. Place the louver in the opening and shim around the
perimeter to maintain proper spacing for backer rod
and caulk joint.
4. Using the appropriate fasteners, secure the
mounting angles to the back of the louver frame at
the perimeter.
5. Ensure the louvers is level and in the correct
location within the opening and secure the mounting
angles to the structure using the correct anchor (by
others) for the building substrate material.
6. Once the louver is secured to the structure, install
backer rod and caulk around the perimeter of the
opening at the front of the louver.

Multiple Section Structural Support
For multiple section wide and single section high louver installation, review Tables to determine if an
additional structural support will be required based on the louver section width and height of the louvers
being installed. If additional support is not required, reference the Multiple Section Wide and Single Section
High-Unsupported installation instructions. If additional support is required, reference the Multiple Section
Wide and Single Section High-Supported installation instructions.

Larger opening sizes require field assembly of multiple louver sections to make up the overall opening size.
Individual louver sections are designed to withstand a 25 psf wind load. Structural reinforcing members
may be required to adequately support and install multiple louver sections within a large opening. Structural
reinforcing members along with any associated installation hardware is not provided by manufacturer unless
indicated otherwise by manufacturer.
