Ventilation Code Requirements

IRC/IBC codes mandate a 1:300 openings ratio of attic square footage for intake, and 1:150 for exhaust points (e.g. ridge vents, gable end vents).

Unbalanced designs demand design adjustments, and Florida/California codes are even more stringent. Computer modeling verifies code compliance before construction.

Proper Ventilation Benefits

Condensation Control

– Balanced intake/extraction prevents moisture accumulation reducing structural damages

Energy Efficiency

– Hot, humid attic air exchange lowers AC costs by preventing heat transfer into living spaces

Durability

– Controlled moisture and temperature swings prolong roof/framing materials’ expected lifespan

Indoor Air Quality

– Prevented mold/mildew growth maintains a healthy interior environment for occupants
