What attic baffle means
An attic baffle is a foam or cardboard chute stapled between rafters at the eaves. It keeps insulation from blocking the soffit vents so outside air can flow up under the roof deck.
Also called rafter vent, insulation baffle.
Where it matters on a insulation job
Blowing insulation without baffles chokes the intake vents and can lead to ice dams and attic moisture. Count the rafter bays at the eaves and add baffles as a line on every attic insulation job.
