Roof Foam Baffles Ventilation

They are known are also known as wind baffle insulation baffles rafter vents or venting chutes.

Roof foam baffles ventilation.

Site built baffles have several possible advantages over manufactured baffles. As with attic floor insulation moisture and heat removal are the reasons for creating proper air. Baffles establish a channel for air to circulate between the insulation and the roof sheathing. Roofs often require ventilation channels directly under the roof sheathing either for a short section of the roof for example near the eaves or for the entire roof from soffit to ridge.

They are usually made from cardboard or rigid foam board or polyvinyl chloride. The dual function design creates ventilation channels under the roof sheathing for healthy air circulation while integral baffles prevent wind washing. When the wind is blowing these ventilation channels allow air to move from the soffit vents to the ridge vents. In brief baffles are designed to provide a channel of air to flow through specific parts of your attic.

When set into place and sealed with spray foam the vent baffles are insulated and air sealed.
