The Edge™ Vent is an intake vent solution for homes with zero overhangs. Its shingle-over, roof-top installed design keeps the roofer on the roof in full control of the project’s exhaust and intake requirements. Stop relying on the siding contractor or the framer for intake vents. It can also be used on roofs with overhangs or up the roof with open soffit construction. At 9 square inches of Net Free Area per linear foot it perfectly balances with most exhaust vents. It passed a stringent 30-day ice dam test. For more information, visit airvent.com.
