Spray Foam Insulation Baffles
Baffles combined with ridge ventilations form a 2 pronged ventilation solution to insulate the roof. Ridge vents are placed on the roof. An end of each ridge vent also has a vent for the gable. Baffles are located on the insulation's lowest edge, either directly under or adjacent to it. This allows for airflow, which helps prevent insulation from getting dampened or deteriorating. Baffling also helps to prevent insulation filling up unwelcome areas in your attic such as exterior walls, floors or ceilings.
Do your heating or cooling bills seem too high? Your crawlspace or attic may not have enough insulation. This problem could allow the conditioned atmosphere to escape into your surrounding area. This will increase your energy consumption, and can result in an expensive and uncomfortable summer.
Some baffles can be used for insulation only and may not take into consideration that the baffles often fall out. Loose-fill insulation should be used for insulation. It fills all spaces to maximize its potential, reduce moisture and improve air circulation (air circulation). If you install insulation without baffles, your rafters space could be too large or too small. Installing baffles will ensure your crawlspace and attic are fully filled.
