We have a Cape Cod-style home with attic vents on each end of the attic, along with a ridge vent. The attic is insulated. These vents are very helpful in the hot summer. However, in the winter the upstairs is very cold. I want to cover the attic vents in the winter when the air doesn’t need to flow through like in the summer. Your thoughts?
I have a similar issue. My 2nd floor does not have a door to the stairwell since the ceiling is angled above the top landing, so a draft pours down the stairs throughout the winter.
