Provent Attic Ventilation System

Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.

Provent attic ventilation system.

Without a wind wash barrier air enters the attic freely and flows above the insulation in the ceiling greatly reducing its r value. Accuvent acts as an all in one wind wash barrier and vent. Provent may be installed prior to soffit panel installation without fear of blow out. Provides the best moisture and air infiltration seal between the rafter vent and wall top plate.

Full joist coverage for maximum air flow. It has high impact plastic construction and can be cut to fit most joist spaces. This can cause moisture buildup and mold growth in the attic which can lead to reduced energy efficiency of the home. Installing attic ventilation channels between the rafters or trusses provides an unobstructed air channel through the insulation.

Provent may be installed prior to the soffit panel installation without fear of blow out. This vent provides full joist coverage for maximum airflow from soffit through insulation. Intake vents located at the lowest part of the roof under the eaves allow cool. Even with cathedral ceilings provent can be cut to fit any joist space.

Without attic ventilation channels air cannot flow freely from the soffit to the exhaust vents. Rafter vent helps keep air flowing in your attic. Polyboard material is waterproof and prevents moisture infiltration secures vent in place eliminating blow out during construction. Install between rafters in an attic.

For over thirty years the proset system has provided penetrators that feature integrated firestopping. They are state of the art sleeving systems that automatically fire stop pipes passing through fire rated floors and walls. The provent 14 in. Ensure proper attic ventilation with the provent 22 in.

The ventilation system is made of tear resistant plastic to help prevent tears from protruding nails install between rafters in an attic provent is the highest quality rafter vent available. Because these penetration systems also contain smoke and water they help reduce overall fire damage. Great for retrofit applications. Install the ventilation system between rafters to provide an air channel through insulation to help keep air flowing freely from soffits to ridge vents.

For conventional attics provent is easily installed in both new and retrofit applications. In a finished attic provent ensures proper air space between the roof deck and insulation. Works well with durovent and provent to provide a moisture impervious vent and block system.
