Foam Insulation Baffles Good Or Bad
We go beyond simplifying installing a baffle, to also installing a blocker and air sealing the exterior top plate seam, which provides our customers with the following benefits: We developed an industry-leading technique to provide maximum insulation performance at the very tight exterior edges of your attic because this often overlooked area is a critical energy efficiency detail. Our skilled crew installs closed cell spray foam at the exterior top plate up to the baffle, see sketch below. This premium process provides the following benefits in addition to the benefits of our standard process:
Are you experiencing poor airflow from your insulation? Is your air circulation poor? Do you need to improve airflow, reduce air leaks or prevent mold from growing? You may need to channel cool, fresh air up onto your roof deck. It's surprising that even the most well-insulated attic space can still need attic baffles to increase air circulation.
Bob Vila explains to us that attics have intake ventilations under the roof's roof eaves, which let in cool air and hot air exhaust vents at its peak that let out hot. Intake vents can be installed in the soffit either as one continuous perforated section or as separate vents spaced every few feet. Vents for gable roofs may be located on the side of your house near the top of the gable.
