Plastic ventilation chutes or insulation baffles are used to create airflow channels in attics that remove moisture in the air and provide temperature control. Plastic chutes for roof ventilation work by protecting your roof deck from the possible condensation that can occur from attic insulation. Plastic attic baffles are made from polyvinyl chloride, a versatile material that is resistant to moisture and corrosion, making it perfect for insulating your home. Handi-Foam's plastic ventilation chutes are also affordable and easy to install.
