Our Retrofit Vent Models are designed to fit on an existing base.
Replace your old, worn and noisy vent heads! AVP’s all aluminum constructed Retrofit Vents are silent, maintenance free and will not rust! Built to last and will fit on your existing bases. These vents exhaust heat and moisture from attic more efficiently, extending the life of your roof.
Unlike the turbine vent, which is open to the sky and allows rain water to enter, our Retrofits instead have vertical louvers that prevent rain and snow from entering. The slotted louvers do not allow insects to build up or collect like an insect screen. It keeps the Vent clean to allow maximum fresh air supply without resistance. Available in several diameter sizes, with powder coating paint options available to match any building material.
