Brentwood's AccuVent® baffles for roof ventilation are designed to save energy for cleaner, greener living spaces. The dual function design creates ventilation channels under the roof sheathing for healthy air circulation while integral baffles prevent wind-washing. AccuVent® offers a quick and inexpensive solution for architects, builders, and renovators to ensure proper insulation performance for better energy efficiency and indoor air quality. AccuVent® baffles are adaptable for any application, roof pitch, or truss size and install quickly and easily with just a few staples. They are manufactured from 100% recycled, flame-retardant PVC - a material that is compatible with all insulation types, including spray foam.
