Aluminum Gable Vents & Exterior Louvers | AirGrilles - old

Exterior louvers move air through attics, crawlspaces, gables, and outbuildings while keeping rain, debris, and pests out. AirGrilles stocks aluminum gable vents and wall louvers built to sit outdoors — the aluminum won't rust, warp, or streak the siding the way painted steel does once the weather gets to it.

Each vent lists both the wall opening size and the overall outer dimension, so you can confirm the rough opening before you order and avoid a second trip up the ladder. Finishes hold up to sun and rain without fading.

Everything ships from US stock same day on orders by 11AM ET, with bulk pricing for builders and remodelers screening a row of units. Order the size that fits your opening and it's on the way before the framing's covered.

FAQs about gable vents & exterior louvers"

How do I measure for a gable or wall vent?

Measure the wall opening (the rough opening cut in the framing or siding). Order to that opening size; the vent's listed outer dimension includes the mounting flange that overlaps the opening. Both numbers are on every product so you can confirm before ordering.

Why aluminum instead of steel for exterior vents?

Outdoors, painted steel eventually rusts and streaks the siding. Aluminum stays rust-proof and color-stable through sun, rain, and freeze-thaw, so the vent keeps looking right for years with no maintenance.

How big should an attic gable vent be?

A common building rule of thumb is roughly 1 square foot of net free vent area per 150–300 square feet of attic floor, split between intake and exhaust. Use your local code and attic size to confirm the total free area you need, then choose vent sizes that add up to it. [General guidance — confirm against local code.]

Do these keep out rain and pests?

Yes — the louvered blades shed rain and the built-in screening blocks insects and debris while still letting the attic breathe.

Is bulk pricing available for builders?

Yes. Bulk tiers apply automatically, useful when screening a full elevation or a run of units, with US stock shipping same day on orders by 11AM ET.
