I bought a 28 year old split level home a little over a year ago. The
attic was never properly ventilated, but is in good shape fortunately.
The attic is a typical crawl-space type.
My brother-in-law, who has a lot of experience in building, suggests
that the best way to add ventilation is to go with a peak vent, and
place foam troughs down into the eaves over the insulation. We would
have to add holes into the soffitts for air to circulate as there are
no holes there at the moment.
Does this sound like the best way to go? Also, can you purchase vents
for the soffitts so that it has more of a finished look without having
to replace the vinyl covering with one that already has holes in it?
