Soffit Vents

They are the most famous type of intake vent. Soffit vents are installed under the eaves of the roof to ensure air ventilation in the roof. They have four further types, i.e.:

Exhaust vents are used primarily to regulate the warm air out of the roof and attic. They are placed at the top or near the rooftop for maximum efficiency. They work passively to vacuum the warm air that protects the roof from extra warmth, reducing energy consumption and moisture buildup.

Pros:
  • Easily available in the market
