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 or black high-density polyethylene with a
locking, vandal proof cap that shields against entry of wind
blown rain or snow. |
