Materials, Methods and Equipment I

Air Barrier Paper

Air Barrier PaperDefinition- a solid membrane material that generally that blocks air flow in one/both directions. It is applied to the exterior, but behind the cladding material. It usually comes in rolls up to 150’ long and up to 14’ tall.

Attic Ventilation

Soffit Vent, Ridge Vent, Gable Vent, Roof Turbine

Soffit VentAttic Ventilation- allows the exchange of air to be cycled through the attic area, as to get rid of stale air and introduce fresh air. It is also used to remove heated air through the ridge/gable vents and allow fresh air in through the soffit vents.

Ridge VentWhat it is doing- It allows attic heat to escape thru the top of the roof.

Gable VentIt allows air to freely enter and escape to keep stale air out of the attic space where the air-exchange unit is usually placed.

Roof TurbineA device that is mounted thru the roof that is powered by the wind outside or sometimes small electric motors, it helps escape hot moist air that is caused in the heating months
