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.
