Flex
InnoFlue® Flex uses industry leading, flame retardant polypropylene technology to construct single wall, gasketed, flexible vent pipes and accessories.
InnoFlue Polypropylene Vent Systems
InnoFlue Flex
InnoFlue® Flex’s dynamic special gas vent product line provides superior corrosion protection throughout. Lightweight polypropylene eliminates installation fatigue associated with most common venting materials, making it easy. The flexible properties of the Vent Length allow for the rapid lining of chimneys, b-vents, and other chases with offsets up to 45°. InnoFlue® polypropylene special gas vent systems are zero clearance to combustibles.
InnoFlue® Flex is used to vent individual appliances. InnoFlue® Flex is commonly combined with InnoFlue® Single Wall but can also be combined with InnoFlue® Concentric.
