These 22" x 48" Perforated Attic Baffles are designed to maintain consistent ventilation from the soffit to the attic, ensuring proper airflow above insulation. Without baffles, insulation can shift and block airflow, leading to heat buildup, ice dams, moisture issues, mold growth, and reduced energy efficiency. Installing attic ventilation channels keeps the attic cooler in summer, warmer in winter, and preserves long-term insulation performance.

Constructed from durable extruded polystyrene foam, each baffle features wide flanges for fast stapling and secure attachment between rafters or truss cavities. The perforated centerline allows each 22" baffle to easily snap into two 11" pieces, giving installers flexibility for tight or narrow rafter bays. The full 48" length ensures you can maintain airflow even with deeper insulation levels, making these ideal for blown-in fiberglass, cellulose, and spray foam hybrid applications.

Perfect for new construction, remodels, attic upgrades, and insulation retrofit work. One ventilation channel per rafter bay is recommended to maintain continuous airflow from the soffit to the ridge or roof vent.

Each box contains 100 perforated vents, providing excellent coverage for residential insulation projects.
