Problem: Backdrafts and Poor Extraction
Imagine an autumn storm where strong wind gusts literally batter your roof. If there is no aerodynamic protection on the exhaust duct, the wind easily blows air back inside. Due to backdrafts, the bathroom becomes freezing, and kitchen smells expelled by the hood return right back to the living room. The wind force is strong enough to completely stall a natural draft or a weaker mechanical fan's operation.
Open ducts on the roof are also highly vulnerable to heavy rain and snow. Moisture entering the ventilation system accumulates in the galvanized steel and eventually causes corrosion and mold, which then spreads throughout your living spaces with the air. This is particularly critical for flat roofs and homes in open areas lacking natural windbreaks.
Transformation: Uninterrupted Draft in Any Weather
Once a roof deflector is installed, the wind is no longer an enemy, but an ally. The deflector's design ensures that wind hitting it creates a low pressure (vacuum) inside the pipe. This naturally "pulls" air out of your home, ensuring smooth and constant ventilation.
Your home is free from ventilation drafts, and the system becomes completely weather-resistant. A special deflector hood prevents raindrops and snowflakes from entering the ducts. You enjoy fresh air and peace of mind, ignoring the raging blizzard outside.
Natural draft enhancement – a properly selected deflector can increase air extraction efficiency by up to 20%, using absolutely no electricity.
