Cool your attic. No new roof penetration. No professional install. A traditional powered attic vent costs $400–800 to install and means cutting a new hole in your roof. That hole risks leaks for years to come — and on still summer days, half of them don't even move enough air to matter. The Zula installs in an existing window cutout or gable vent. Three industrial fans powered by a 75W solar panel. No roof penetration. No new holes. No electrician. The fans run whenever sun hits the panel — which is exactly when your attic gets unbearable. 15 minutes with a screwdriver. Zero risk to your roof. Zero ongoing cost.
