VENTS & BREATHERS

Relief of trapped moisture in all types of roof system
Portals Plus insulation Breathers and Vents are used to prevent moisture vapor from becoming trapped in the roof system, equalizing air pressure, reducing the risks of ballooning, blow-off, deteriorating insulation and separating deck seams. The Portals Plus Vents have a one way valve designed in the unit to prevent moisture from re-entering the roof system. The Portals Plus Breathers allow for both exhaust and convective movement of air between breathers. Both the Breather and Vent are available in heavy gauge spun aluminum, black high-density polyethylene, white U.V. stabilized PVC, or white TPO (thermoplastic olefin) with a locking, vandal proof cap that shields against entry of wind blown rain or snow.
