The CV3 ridge vent is a patented two-piece foam closure with screened windows that allows hot air to circulate from the inside of your building out through the ridge cap， keeping your metal building ventilated and free of damaging condensation. The CV3's baffle system offers complete protection from infiltration of blowing rain and snow on lower pitched roofs and the CV3 is also recommended in regions of the country that experience extreme weather conditions. Since even small amounts of condensation can substantially reduce the \"R\" value of the insulation， creating faster heat loss into the attic space and eventually leading to mold， mildew， rot， ice damming and loss of energy efficiency， it is important to ventilate this area. CV3 is an affordable， easy to install， self-cleaning， totally concealed option to safely vent the hot air from your metal building. It provides a continuous line of ventilation down the entire ridge line. When used in conjunction with intake or soffit vents， air moves outward through the screened closure， allowing fresh air to flow while blocking debris. It is die cut to perfectly fit the Classic Rib panel profile and is a safe and affordable ventilation choice for lower pitched roofs.
