“Failing to properly install intake ventilation can render your attic ventilation system virtually useless!”
Many homes in North America have inadequate attic ventilation systems. Inadequate attic ventilation can often be attributed to homes having little or no intake ventilation. Failing to properly install intake ventilation can render your attic ventilation system virtually useless.
Efficient attic ventilation systems are similar to the human body. Intake ventilation provides the cool, fresh air into the system, similar to the body inhaling. Exhaust ventilation (commonly ridge vents) allows the moist, warm air to exhaust from the system, similar to the body exhaling.
Cape Cod-style homes with no soffits, mansard roofs, or even vented roof deck systems are extremely challenging to properly ventilate, especially with intake ventilation. To make matters worse, homes with existing soffit or undereave vents can have ineffective intake ventilation because their vents have become clogged with dirt or have been painted over.
