SlopeShield Diagram WebImage 01SlopeShield Plus SA is a self-adhering air barrier and permeable vapor retarder within the finished roof system; controlling moisture, blocking air, and improving performance

  • SlopeShield Plus SA can be installed on:
  • Self-drying technology facilitates damp substrate (insulation, concrete, wood etc) drying, allowing for component reuse in reroof applications
  • Fully self-adhered, aggressive, patented, pressure sensitive adhesive is protected by a siliconized release film, which is removed during installation 
  • Exceptional air barrier and permeable vapor retarder, curbs air leakage and manages moisture within the building envelope
  • Transitions to an air barrier and permeable vapor retarder within the finished roof assembly, greatly reducing condensation 
  • Code compliant, engineered to meet/exceed standards set forth in IECC and IBC. 
  • 6 months UV and climate exposure prior to roof system installation 
  • Tough, durable, and Slip Resistant - With Excellent Traction for Installers
  • Primerless application 
  • Suitable for All Climates and Geographic Locations, Including Extreme Temperature Areas
  • 20 Year Material Warranty

Self-Drying Technology Re-Roof Projects

Newark Airport 70web DCIM\100MEDIA\MAX_0039.JPG
The Newark Airport terminal needed a reroof, but also to keep the terminal functional. Over 375,000 sq.ft of SlopeShield Plus SA met the challenge.  View the project details. The overburdened vegetative green roof was leaking into residences. Installing SlopeShield Plus SA allowed residents to remain in the condos during reroof.  View the comprehensive case study.
