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?
Yes insulation should never touch the sheathing unless it is meant to & designed as a hot roof system. The other item is future proofing - they may close off gables &/or install soffit venting later or even add inline / intake/ eave whatever they wish to call it venting later
