What is the best way to ventilate an attic with a "knee wall?"
Last Updated 11 years ago
A knee wall exists when a room is built within the attic cavity. The lower attic area is separated from the upper attic area. Lomanco recommends that insulation baffles be used between every rafter where the ceiling of the knee wall meets the sloped rafters. This will facilitate a system of intake to the exhaust vents located in the upper portion of the attic.
