Roof Air Flow Baffle

One aspect of the invention is an insulation stop which can be installed between the top wall plate and the roof deck to act as a rigid air barrier and to prevent.

Roof air flow baffle.

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. A baffle is a way to push and keep down the insulation in order to create an air space that allows air to travel under the decking. No insulation should be in the 2 chute created when bending up the side flanges against the roof deck. In brief baffles are designed to provide a channel of air to flow through specific parts of your attic.

Baffles establish a channel for air to circulate between the insulation and the roof sheathing. As with attic floor insulation moisture and heat removal are the reasons for creating proper air. That airflow is intended to churn the stale air in your attic which helps to remove moisture and control the temperature of your attic. They are known are also known as wind baffle insulation baffles rafter vents or venting chutes.

Basic functions of baffles. The soffit vents allow convective air movement from the soffits of the residence to the ridge vent. Smartbaffle16 and smartbaffle24 are designed to allow 2 of air flow between 16 and 24 on center rafter spaces respectively. The picture below courtesy of the epa indoor airplus program which we provide builder verification services for helps show how the system works.

From left to right air flows through the soffit vents up over the baffles allowing for the required roof venting. An attic baffle is simply an item to regulate the flow of air aka required roof venting and impede it the insulation from interfering with each other. The beauty of attic baffles is that they are available from most. In addition insulation baffles must be installed at the point where the attic floor meets the roofline to prevent the attic insulation from migrating into the cavities and restricting the airflow from the soffit vents.

The present invention is directed to a cardboard baffle which can be installed between adjacent roof rafters to regulate the flow of ventilating air into and out of the attic. Wider or narrower rafter spaces can be accomplished by following the directions enclosed with the product.
