Can I just put faced insulation over the louvers? Is there a better way of insulating this fan? The shutter cover that I found on line only has an R value of 6.

Remove the entire unit and install drywall and tape, then insulate properly. 2. Are you sure you want to stop using the fan? They are great energy savers.

Pop the top in the summer months and use the fan as intended. Best of both worlds. __________________ To view links or images in signatures your post count must be 10 or greater.
