InnoviFlash^™ 2-Way Breather Vents are used for easy installation of IKO Innovi^™ TPO thermoplastic polyolefin single-ply roofs. InnoviFlash 2-Way Breather Vents help reduce moisture by allowing air movement within the roofing assembly together with 1-way vents, which allow trapped air pressure to escape. InnoviFlash 2-Way Breather Vents make heat welding fast and easy, resulting in labor savings during installation. The vents are also designed with vandal-proof caps. These white vents are available in the following size: 4 inches (101.6 mm); height: 9 inches (229 mm); diameter: 4.25 inches (108 mm). The flanges, which measure 7.5 inches (190.5 mm), are made up of a 60-mil, reinforced TPO membrane. InnoviFlash 2-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.
