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.

Provent attic ventilation system.

It has high impact plastic construction and can be cut to fit most joist spaces. Install between rafters in an attic. Installing attic ventilation channels between the rafters or trusses provides an unobstructed air channel through the insulation. Works well with durovent and provent to provide a moisture impervious vent and block system.

For over thirty years the proset system has provided penetrators that feature integrated firestopping. For conventional attics provent is easily installed in both new and retrofit applications. Ensure proper attic ventilation with the provent 22 in. Install the ventilation system between rafters to provide an air channel through insulation to help keep air flowing freely from soffits to ridge vents.

Great for retrofit applications. Install the ventilation system between rafters to provide an air channel through insulation to help keep air flowing from soffits to ridge vents. Provent may be installed prior to soffit panel installation without fear of blow out. Without attic ventilation channels air cannot flow freely from the soffit to the exhaust vents.

Rafter vent helps keep air flowing in your attic. They are state of the art sleeving systems that automatically fire stop pipes passing through fire rated floors and walls. Provent may be installed prior to the soffit panel installation without fear of blow out. The ventilation system is made of tear resistant plastic to help prevent breakage and can be cut to fit most joist spaces.

In a finished attic provent ensures proper air space between the roof deck and insulation. The ventilation system is made of tear resistant plastic to help prevent tears from protruding nails. The provent 14 in. Accuvent acts as an all in one wind wash barrier and vent.

Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. Intake vents located at the lowest part of the roof under the eaves allow cool. Polyboard material is waterproof and prevents moisture infiltration secures vent in place eliminating blow out during construction. This vent provides full joist coverage for maximum airflow from soffit through insulation.

Even with cathedral ceilings provent can be cut to fit any joist space. 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.
