Remove all the existing attic insulation and thoroughly clean the attic floor.
Install insulation baffles as required along the roof edge, or above each attic ventilation port if it is not a continuous soffit vent.
Install batt insulation into every empty joist space to block new blown-in attic insulation from entering the soffit space.
Air seal non-IC/AT-rated pot lights and other electrical fixtures, combustion exhaust flue vents, and large holes prior to flash coat. Failure to do so can result in spray foam in undesirable locations or damage to existing components.
Flash coat the entire attic floor with a coat of spray foam to create a continuous air seal.
