Louvered Exhaust Vents

PlyGem says that its 4-inch and 6-inch Exvent and Exvent6 louvered exhaust vents have an improved design for easier installation A two-piece snap-on design and integrated trim rings eliminate the need to assemble multiple parts or cut complex shapes into siding. These products are able to accommodate ⅛-inch airflow adjustments and feature optional, removable screens to protect against insects and pests. The vents come in molded colors, but they can also be custom painted to color-match the siding. plygem.com
