InnoviFlash^™ TPO 1-Way Breather Vents are used for easy installation of IKO Innovi^™ TPO thermoplastic polyolefin single-ply roofs. InnoviFlash TPO 1-Way Breather Vents help reduce moisture by allowing air movement within the roofing assembly together with 2-way vents, which allow trapped air pressure to escape. InnoviFlash TPO 1-Way Breather Vents are heat-welded quickly and easily, resulting in labor savings during installation. The vents are also designed with vandal-proof caps. These white vents are available in the following sizes: 4 inches (101.6 mm); height: 9 inches (228.6 mm); diameter: 4.25 inches (107.9 mm). The flanges, which measure 7.5 inches (190.5 mm), are made up of a 60-mil, reinforced TPO membrane. InnoviFlash TPO 1-Way Breather Vents are important components in the successful installation of an IKO InnoviTPO commercial roofing system and can help qualify for an appropriate IKO Diamond Shield Limited Warranty.
