I installed an exhaust fan earlier this year close to a ceiling vent.
It comes on with a thermostat and the vent is automatic with heat rise.
I wanted to close it off this winter but I still need it now.
So. I insulated the vent itself and I added a drop-down ( Dr. Denton ) stlye panel for access.
The drop-down is held closed w/ velcro and I added a string to pull it open.

Works good as long as you open the drop-down.
I'll seal the whole thing with tape when I have to.

ha ha, pretty crude ehh?
