Homemade Attic Baffles

The book that helped us build and renovate.

Homemade attic baffles.

Staple each side to the roof deck spaced about every 4 inches. The outside edge of the baffle should be parallel to the exterior wall sheathing. Sometimes called rafter vents baffles provide ventilation and keep the insulation from blocking airflow through your attic. You ll need to crawl to the end of the eave and staple the baffle against the roof deck.

Surprisingly even the most well insulated attic space may still require the assistance of attic baffles to provide the additional air circulation. It is a fairly easy process that will make a world of difference in assisting your insulation and keeping your home protected from rot which can save you a substantial amount of money down. The secret is a homemade cutting jig that holds a utility knife blade. The rigid foam is cut to be 2 inches wider than the space between rafters then 1 inch of foam is scored and folded over on either side of the foam creating standoffs that hold the foam away from the roof sheathing providing a space for air to flow.

The beauty of attic baffles is that they are available from most home improvement stores and can be installed simply with a few staples if you want the diy approach.
