Solar Power Ventilation
I will be installing a solar powered attic fan. attic access is through a 3'x3' opening in garage ceiling.?
should i close this opening to allow ventilation through soffit vents? or maybe keep it open during winter or summer? the opening is at the opposite side of attic from fan. garage is not heated. thanks!
I would close the opening when not in use for proper attic venting as you mentioned plus to conform to Fire Hazard Prevention needs. The opening should have the same rating as the rest of the ceiling in normal mode to prevent fire from easy access to the attic structure.
When budget cuts hurt energy saving New Jersey's record-breaking heat this summer had a soundtrack, it would air conditioners were the sound of millions of sums.
