Attic, Roof, & Whole House Fans

Types of Attic, Roof & Whole House Fans

Whole-house fans come in many different styles. Whatever your air quality needs, reducing moisture or improving airflow, Sylvane has the device you need.

Our lineup includes:

• Attic Fans: Reduce heat buildup in your upper floors with an efficient attic fan that exhausts hot air and draws cool outside air in.
• Roof-Mounted Fans: Ventilate your attic with a roof exhaust fan installed directly into the building. Ideal for buildings without gable vents.
• Whole-House Fans: Keep your mornings and evenings cool with a whole-house fan in a central location. These pull cool outdoor air through open windows and exhaust hot indoor air through the attic.

Use Cases

Our high-grade indoor fan options offer much more than standard fans. These innovative devices are critical air quality components designed to improve your quality of life while keeping your energy bills low. 

Here’s where they make the biggest impact:

• Residential Homes: Improve your year-round comfort by expelling hot, stale air from upper floors (while also reducing your energy bills).
• Commercial Buildings: Keep workers comfortable and stock safe by properly ventilating storage spaces and important upper floors.
• Moisture Control: Combat potentially dangerous condensation and mold growth in attics and roofing structures, and improve your property value.
• Seasonal Cooling: Use a whole-house fan to replace or supplement air conditioning during cooler evenings.
• Energy Efficiency Upgrades: Reduce your HVAC dependency (not to mention your HVAC bills) with more eco-friendly roof and whole-house fan systems.

FAQs

What’s the difference between an attic fan and a whole house fan?

An attic fan reduces heat buildup in only the attic. A whole-house fan pulls cool outdoor air through open windows and exhausts it through the attic.

How do I choose the right CFM rating for my space?

Match CFM to your attic’s square footage. For whole-house fans, aim for 2–3 CFM per square foot of living space.

Can these fans be installed in all roof types?

Most can be installed in standard-pitched or gable roofs, but flat or unusual roof structures may need special mounting kits.

Will a whole-house fan lower my cooling costs?

Possibly. When outdoor temperatures are cooler, a whole-house fan can dramatically cut AC usage.
