What does this wall louvers and vents final checklist cover?

13 items across 4 sections, covering set and perimeter seal, screens and blank-off, duct connection, finish and records. Each item spells out what the person walking the job is actually looking for, not just a box to tick.

Who should run this inspection?

The louver installer with the GC's superintendent, walking set louvers after cladding and before turnover.

When in the schedule should this walk happen?

After louvers are set and the perimeter is sealed, screens and blank-off panels are installed and the duct is connected, before turnover walks.

Why do these items ask for a photo?

9 of the 13 items call for photo evidence, 11 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.

What most often fails a wall louvers and vents final inspection?

Perimeter sealant run over the drainage path at the sill, so the flashing that was meant to weep is sealed shut and trapped water backs up behind the frame. Bird or insect screen omitted, torn or fitted to the wrong side of the blades, so the opening passes visually but lets pests and debris into the duct. Blank-off panel left out or unsealed behind a partial louver, so conditioned air bleeds around the duct collar and the intake pulls unfiltered attic or wall-cavity air.

Can I use this checklist in RTI?

Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.

Wall louvers and vents final inspection checklist

Wall louvers and vents final inspection is where the punch list is either short or expensive. This checklist walks the finished work the way an owner or AHJ will see it: devices on, systems running, everything labeled. Each item gets the photo that closes it instead of reopening it. Work is commonly verified against the applicable building code, SMACNA guidance, manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Set and perimeter seal

Louver true in the opening, perimeter sealed and draining
Frame plumb and square, even reveal to the cladding, continuous tooled perimeter seal over a backed joint with the sill weep path left open to drain.
Frame anchors at the submitted spacing into blocking
Anchors at the spacing on the approved submittal and seated in the blocking, heads concealed or finished to match, frame not bowed by overdriving.
Frame label and blade profile match the schedule mark
Frame label read for model, size and mark, and the blade section shows the drainable, stormproof or other profile the schedule lists, not a look-alike substitute.
Blades straight with their drain paths clear
Blades evenly spaced and undamaged, blade gutters and jamb drains free of sealant, debris and fasteners so caught water reaches the sill and runs out.

Screens and blank-off

Bird and insect screen and blank-off panels in place
Screen intact and fastened on the correct face, mesh matched to intake or exhaust, blank-off panel installed and sealed behind any area not connected to duct.
Screen reachable for cleaning from the side the detail shows
The screen frame can be removed or reached through the access the details provide, not trapped behind duct, ceiling or blank-off work.
No photo

Duct connection

Duct connection sealed and airflow confirmed
Louver collar sealed to the duct with no gaps around the transition, damper if present operates, airflow at the louver confirmed in the intended direction.
Mechanical connection kept clear of blade drains and the sill
From the louver side, the duct collar or plenum attaches to the frame without fasteners or sealant blocking blade drains, jamb drains or the pan.
Wall below each louver dry inside after rain or a wet-down
Interior face below and beside the frame checked after the first rain or a hose wet-down, with no water at the sill, framing or duct floor.

Finish and records

Louver finish matches the approved color sample
Frame and blade finish viewed in daylight against the approved sample, consistent across multi-section louvers and with the adjacent cladding trim.
Every scheduled louver set at its mark
Each mark on the louver schedule accounted for at its opening, with intake and exhaust louvers where the mechanical drawings put them.
No photo
Published water and airflow data on file for each model
The manufacturer's published free area, water penetration and pressure drop data for the installed models are in the closeout set with the approved submittal.
No photo
Louver finish warranty in the closeout set
The finish warranty and any installer warranty the spec requires are submitted and name the louvers and finish actually installed.
No photo

What usually sends this back

The failures are almost always the evidence, not the work

Perimeter sealant run over the drainage path at the sill, so the flashing that was meant to weep is sealed shut and trapped water backs up behind the frame.
Bird or insect screen omitted, torn or fitted to the wrong side of the blades, so the opening passes visually but lets pests and debris into the duct.
Blank-off panel left out or unsealed behind a partial louver, so conditioned air bleeds around the duct collar and the intake pulls unfiltered attic or wall-cavity air.
