STV-51 시리즈 사각 상단 고정 환기구, 6팩

The 51 sq. in. NFA per vent made a noticeable difference in my attic airflow, and the integrated pest screen was a nice bonus. They were straightforward to install and seem built to last.

I installed these in my attic last weekend and the square top design makes them sit flush against the roof—definitely looks clean from the street. The 51 sq. in. NFA per vent seems to be pulling a noticeable amount of hot air out already.

The integrated pest screen is a huge relief—no more worrying about birds or wasps getting into the attic. These vents were straightforward to cut in, and the square top blends in nicely with the roofline. My upstairs rooms already feel less stuffy in the afternoon sun.
