Built for the DIY install

15 minutes. One screwdriver. Done.

Most home cooling solutions require an electrician, a roofer, or both. Powered attic vents need wiring. Window AC units block your window. Even most "DIY" solar vents require complex mounting hardware and roof work.

The Zula is sized to fit standard 21" × 14.5" garage door window cutouts and shed gable vents. You pop out the existing window or vent (4–8 screws, save them), drop the Zula in, screw it down, connect a single on/off switch wire. Walk outside. Done.

We've watched first-time homeowners do this in 12 minutes. The solar panel takes over the second sun hits it. No app, no calibration, no maintenance.

What you get

Engineered for the homeowner, not the contractor.

☀

Powered by sunlight

A 75W solar panel runs the fans whenever the sun's up. No wiring to your panel, no batteries to swap, no monthly bills. The hotter the day, the harder it works.

💨

Real airflow, not a breeze

630 CFM combined across three 120mm fans spinning 5,000–7,000 RPM. Enough to fully cycle a two-car garage's air every few minutes.

🔩

No roof work, ever

Drops into an existing garage door window cutout or a 21" × 14.5" hole. Screwdriver only. No drilling new holes, no roof leaks, no electrician.

Where the Zula fits

One unit, four spaces, infinite uses.

Garage doors

Replace a standard garage door window pane. The most common install, and the easiest. Compatible with Wayne Dalton 9100 Sonoma, Clopay, and other major brands.

Sheds & barns

Replace passive gable vents with active fans. Trusted by NC Shed Builders, Beachy Barns, and dozens of US shed builders who include the Zula as a standard upgrade.

Attics

Ventilate without roof penetration. No new holes, no leak risk, no professional install required. A retrofit alternative to roof-mounted attic vents.

Greenhouses & workshops

Keep growing temperatures stable in greenhouses. Vent fumes from a hobby workshop. Pest-proof — the active fans deter birds and insects from nesting.

Chicken coops & pet rooms

Keep animals comfortable in summer. Eliminate ammonia buildup. The fully solar design means zero ongoing electricity cost.

Tiny homes & remote buildings

Off-grid cabins. Tree houses. Pool houses. Tiny homes. Anywhere a power line doesn't reach but you still need active ventilation, the Zula works.

Zula vs. a passive roof vent

It's not the same thing.

Roof and gable vents are passive — they only move air when wind is moving. Here's what changes when you replace one with a Zula.

The Zula

Powered by sunlight — moves air even on still days
Drops temp 20–25°F vs outside
Installs in your existing window cutout
Pest-proof — fans actively deter birds & insects
One-time $299, zero ongoing cost
15-minute DIY install, screwdriver only
80,000 hours of operating life
No roof penetration — zero leak risk

Passive roof/gable vent

Wind-dependent — dead air on still days
No measurable cooling effect
Requires roof penetration ($400–800 install)
Birds nest, insects enter freely
Risk of roof leaks for years to come
Professional install required
Replaceable parts wear out
Adds new holes to your roof

The story

Built in a garage, for garages.

The Zula started as a backyard problem. The inventor — a Cary, NC engineer with a hot garage — couldn't find a ventilation product that actually moved air on still days without requiring a roof penetration or an extension cord. So he built one in his garage, using hardware-store parts and three industrial cooling fans.

After early prototypes proved themselves with neighbors and a local shed builder, the company moved to formal manufacturing in North Carolina. Today the Zula is listed with the International Door Association, ships from a North Carolina facility, and is integrated into the build configurators of regional shed builders like NC Shed Builders.

The name "Zula" was chosen for its African origin meaning to inspire — a nod to the kind of small, useful design we want every garage and shed to have.

FAQ

Everything you might ask.

Will the Zula actually keep my garage cooler?

Yes. The Zula keeps garages 20–25°F cooler than outside temperatures by continuously circulating air. It's not an air conditioner — it doesn't refrigerate — but it actively replaces hot, stagnant air with outside air, even when there's no wind. On a 100°F day with the unit running, your garage typically sits at 75–80°F.

How hard is the install really?

If you can use a screwdriver, you can install the Zula. Pop the existing window out (4 to 8 screws depending on your door), drop the Zula in, screw it in place, connect a single on/off switch wire. The unit fits standard 21" × 14.5" cutouts. Most installs take 15 minutes. No electrician, no roof work, no drilling new holes.

What if there's no sun? Does it stop working?

The Zula runs while the sun is hitting the panel — which is exactly when you need ventilation most (hot, sunny days). There are no batteries to maintain. On overcast days, it operates at lower output. At night, when the sun isn't a problem, the unit rests. For continuous operation, an optional hardwire is available — contact us.

Can birds or insects get in?

No. The Zula's fan openings are screened, and the moving fans themselves actively deter birds from approaching or nesting. It's significantly more pest-resistant than a passive gable vent.

How loud is it?

64 dB-A. That's about the volume of a normal office conversation, or a quiet dishwasher. From inside your house, you won't hear it. Standing right next to the unit, it's clearly audible but not unpleasant.

What garage door brands is it compatible with?

Most standard residential garage doors with a 21" × 14.5" window cutout. We've confirmed compatibility with Wayne Dalton 9100 Sonoma, Clopay, and most other major US garage door brands. If your door uses a non-standard window size, contact us before ordering — we can sometimes accommodate.

Does this work for sheds, attics, greenhouses — not just garages?

Yes. The same unit replaces gable vents on sheds and barns, ventilates attics without roof penetration, and works for greenhouses, workshops, chicken coops, and other remote structures. NC Shed Builders and Beachy Barns are two of many partners who include the Zula in their builds. As long as you have a 21" × 14.5" cutout (or can make one), the Zula fits.

What's in the box?

One Zula ventilation unit (21" × 14.5"), one 75W polycrystalline solar panel (21" × 15"), on/off switch and wiring, mounting hardware, and an illustrated install guide. Nothing else to buy.

How long does shipping take?

Free US shipping. Orders ship within 1–2 business days from North Carolina. Most US destinations arrive in 5–7 business days. Remote areas (Alaska, Hawaii, US territories) may take 7–14 days.

Does it ship to Canada or internationally?

We're shipping within the continental US only for now. International availability is coming — email info@zulaventilation.com to be notified.

Where can I see one in person before buying?

Demo Zula units are installed at NC Shed Builders' showroom in Durham, NC (1400 E. Geer St.) and at several other partner shed builders across the US. We're also frequently at trade shows — see the list above. Email info@zulaventilation.com if you'd like the nearest demo to your ZIP.
