Insulation Vent Chute

The Johns Manville Vent Chute are extruded polystyrene (XPS) sheets thermoformed to provide airflow from the soffit to the attic space when installed between insulation and the roof deck. This is a versatile and efficient solution for improving ventilation and air flow in your home or building. This product is designed to channel air through insulation, preventing moisture buildup and promoting a healthier indoor environment. Vent Chutes can be installed in finished or unfinished attics with open rafters in both new and retrofit construction to fit both 16″ and 24″ on-center cavities.
