Expert Verdict Reviewed by the SuperArbor Pro Desk

Baffles are essential whenever you add attic insulation, because blown-in or batt insulation will otherwise block the soffit-to-ridge air channel. Install SmartBaffles against the sheathing at each eave before insulating, and staple or fasten them so they stay put under blown insulation. Cut halves at the eave where you want extra protection over the lower courses. Pick the 16 in. or 24 in. model to match your actual rafter spacing.

Wear a dust mask and eye protection when working in attics, and take care not to dislodge wiring orVent materials while fitting baffles against the sheathing.

Order the DCI SmartBaffle 24 in. baffle to keep attic ventilation open above your insulation.
