Optimizing your attic's ventilation has never been easier, cleaner, or more accurate. Welcome to VentAttico—the premium, local-first attic ventilation calculator designed for homeowners, builders, roofing professionals, and building inspectors. Built with a sleek, modern interface, VentAttico simplifies complex building code requirements into effortless, visual calculations. Proper ventilation is crucial to preventing heat buildup, moisture damage, and ice damming. VentAttico ensures your projects comply with international building standards while maintaining the perfect structural airflow balance. --- KEY FEATURES: • ACCURATE CODE COMPLIANCE Calculate net free ventilating area (NFVA) requirements instantly using standard building regulations. Swap between the 1/300 rule (for balanced systems with vapor retarders) and the 1/150 rule (for unbalanced or complex attic spaces) with a single tap. • ACTIVE INTAKE & EXHAUST BALANCING Achieve the gold-standard 50/50 balance. Enter your planned intake (soffit/eave) and exhaust (ridge/roof) vents, and VentAttico will automatically analyze the distribution. Get real-time feedback and smart warning alerts if your ventilation setup becomes unbalanced or exhaust-heavy. • CUSTOM VENT TEMPLATE LIBRARY Ditch generic calculations. Save your favorite vent models (standard soffits, specific ridge vents, box vents, and turbine specs) in your personalized local library. Select a saved vent, and the app instantly tells you exactly how many units you need to purchase and install. • SEAMLESS DUAL-UNIT SUPPORT Work the way you want to. Toggle dynamically between Imperial measurements (square feet, inches) and Metric measurements (square meters, centimeters) directly on the calculator view or in settings. • SLEEK, MODERN DESIGN Calculations don’t have to look boring. Experience a beautiful, premium iOS utility featuring full Light and Dark mode optimization, glassmorphic design elements, and fluid animations. • ZERO DATA TRACKING & LOCAL FIRST Your privacy is our standard.
