Exhaust out hot moist air in the summer and damp wet air in the winter with roof vents.

Passive vs active roof vents.

In order to facilitate this exchange of warm and cool air the general rule. Active ventilation products has exhaust roof vents for both flat roofs and pitched roofs. Active roof vents will exchange the air inside the attic with fresh air from the outside many times faster than passive vents. This is because active airflow is more consistent than passive airflow.

You don t want that kind of hot air in your house especially not in the winter. Passive vents are fine powered vents are almost always a really bad idea. Blowing in more insulation is another possibliity. A simple passive system uses no energy will work just as well for free as a powered active system and in almost all instances has the benefit of being silent.

Whilst it is possible to retrofit passive ventilation solutions to existing buildings it is highly recommended to incorporate passive ventilation during the design phase of any new building project. Sealing any air leaks between the house and the attic provides the most benefit. It is possible that a radiant barrier will pay for itself in a reasonable amount of time. The most common types of active vents include wind turbines wire powered vents and solar powered vents.

The benefits of passive roof vents. A well insulated well designed home may only need to use active ventilation for rooms where moisture is generated bathroom laundry and kitchen while passive ventilation will be sufficient for maintaining air quality through the rest of your home. Achieving calculated continuous and unimpeded airflow through the roof cavity is relatively straight forward. It can also get trapped in the attic and cause quick melting of the snow which then runs down the roof and refreezes causing ice dams.

Roof vents will add years of life to your roof and will make your home or building more energy efficient. Taking advantage of this natural process referred to as passive ventilation is the most common way to vent an attic. Attic must have 5 sq. Hip roof with not much space vents.

Good attic ventilation is important for preventing ice dams in the winter. These can be ridge vents wind turbines or the flat vents your roofer wants to install. Active ventilation is a system that provides air circulation in indoor spaces using mechanical fans. Ft of vent space half dedicated for air intake in the soffits and the other half for exhaust on the roof.
