Roofing and attic ventilation refers to the way air and moisture enter or leave a home. See the benefits of attic ventilation a new roof is more than just shingles. Natural airflow wind and the temperature differences in indoor and outdoor air help to draw in fresh air and circulate it through the home.

The other is a home s mechanical ventilation system.

The keepa attic vent is used for ventilating attics and or plenum as a roof exhaust vent or as an air intake roof vent. It alleviates moisture in the winter and heat in the summer to extend roof membrane life. Taking advantage of this natural process referred to as passive ventilation is the most common way to vent an attic. One of the natural types of ventilation systems is where air flows through windows and cracks and around door frames.

The early to mid 20th century saw the development of this concept.

The keepa attic vent is built exclusively for flat roof ventilation roof pitch is 2 12 or less. Like natural ventilation systems with windowmaster mixed mode ventilation systems utilize sensors to monitor indoor temperature co2 levels and humidity as well as outdoor conditions. Roof vents enhance the overall comfort of the house by providing escape hatches for hot stale moist air which can reach temperatures of 150 degrees in summer.
