FlashCo's One-Way and Two-Way Breather Vent helps deliver pressure equalization within the roofing assembly to reduce moisture and release trapped air. The One-Way vents allow trapped air pressure to escape, and Two-Way vents, in conjunction with the One-Way vents, help to reduce moisture by allowing air movement within the assembly. The base and cap are not only compounded for superior strength but also with a weathering package that is second to none. For all non-white TPO applications FlashCo prefabricates a boot that goes over the base prior to cap being attached. Therefore, if your field membrane is PVC or any color FlashCo has you covered. The cap however only comes in white and could be painted to match.
