Hi all - I recently saw a contractor installing baffles in an attic that didn't have soffit vents - they had gable vents. Do others see this? And are there real benefits to this, maybe by keeping the insulation from touching the underside of the roof to protect it from extreme temps or condensation? Do others think the time/costs are worth it?
Sounds like a case of "old habits die hard". The sub contractor was probably just installing the things they've always been told to put in. Having no soffit venting is fine (my own 1930's home only has gable vents) but the attic needs to be very well air sealed to prevent air flow (re: moisture) migrating up from the living space.
Unless the soffit is caulked or foamed sealed there's lots of holes. Some time put smoke/fog/light in an attic and see the holes. I was watching fiber glass breath the smoke with air flow.
