Attic vent. I enjoy one to be exact call a whirrly bird, does it involve to be coved up for the winter months? ...
Answers: No. Even if you covered it, the amount of savings on your electricity or heat fuel bill would be zilch. Your type of attic is considered a unheated/uninhabitable space, it will get hot and cold depending on the heat. Best you can do is add more insulation, any blow in (looks similar to fluff) or batt insulation. I wouldn't worry in the region of it. Chow
