Install Attic Ventilation Channels

Baffles are also called wind baffles venting chutes rafter vents or insulation baffles.

Install attic ventilation channels.

Baffles provide a channel for air to flow through certain parts of the attic. The provent rafter vent channel provides an unobstructed air channel through your insulation. Continuous or individual soffits. Provent may be installed prior to the soffit panel without fear of blow out.

Attic rafter vent baffles are essential for the health of your roof. Attach this roof and attic insulation treatment using foam baffles to ventilate insulate and channel cold and hot air to roof vents before insulation is add. Soffit vents are the small metal or plastic grates you probably have seen under the eaves of houses. Attic ventilation channels baffles are needed to prevent the insulation from filling the space between the ceiling and the roof sheathing along the eave edges.

Provent may be installed prior to the soffit panel without fear of blow out. To install the rafter vents staple them directly to the roof decking. Rafter vents ensure the soffit vents are clear and there is a channel for outside air to move into the attic at the soffits and out through the gable or ridge vent. They allow the fresh air to travel up under the roof to the ridge or gable vents keeping the roofing materials dried out and in good working order.

Adam left and max right install luan plywood panels between the i joists to create continuous vent channels and windwash baffles. They are easy to install under the roof s overhang which is known as the soffit are generally hidden from sight and provide excellent protection from weather outdoor debris and pests while still allowing air to flow into the attic. Finally to ensure that the airway to the vent remains open staple a ventilation baffle to the plywood sheathing in each rafter bay. Soffit vents are one of the most popular intake vent styles.

In order to facilitate this exchange of warm and cool air the general rule of thumb suggests installing at least 1 sq. Improper attic ventilation prevents the free flow of air from the soffit to the exhaust vents which reduces insulation efficiencies and accelerates moisture problems. Rafter vents come in 4 foot lengths and 14 1 2 and 22 1 2 inch widths for different rafter spacings. The provent attic ventilation channel provides an unobstructed air channel through your insulation.
