Highly Advanced Roofing UnderlaymentSlopeShield Plus Self-Adhered (SA) vapor permeable roofing underlayment is designed for use on steep slope roofs of 2:12 or gather pitch. The revolutionary roofing underlayment features the patent-pending Vapor Permeable Polymer Composite Technology (VPPCT™). The exclusive VPPCT process creates a new class of roofing underlayment capable of being watertight and vapor permeable. |
SlopeShield Plus SA is engineered with an advanced patent-pending combination of polymer coatings and adhesive technology making it both watertight and vapor permeable. |
New Material AdvancementVaproShield’s new roofing underlayment, SlopeShield® Plus Self-Adhered (SA) represents a significant advancement in performance over the previous polypropylene-based version of SlopeShield and similar competitive products. SlopeShield Plus SA is engineered with VaproShield’s patent pending Vapor Permeable Polymer Composite Technology (VPPCT™). VPPCT™ is an advanced combination of polymer coatings and adhesive technology developed by VaproShield Research and Development to create a new class of roofing underlayment capable of being:

SlopeShield Plus SA is both air tight and vapor permeable allowingSlopeShield Plus SA is both air tight and vapor permeable allowingthe roof assembly to perform to its maximum life span. |
Roof Assembly Needs to BreatheBy designing a roof assembly that incorporates a vapor permeable, water resistive air barrier underlayment, moisture issues from interior vapor drive and construction moisture can be mitigated allowing the roof to perform, as designed, to its maximum life span. With its high level of permeability SlopeShield Plus SA is the answer to condensation issues that frequently occur in metal roofing applications using vapor barrier underlayments.

Innovative Pressure-Sensitive Adhesive
SlopeShield Plus SA utilizes VaproShield’s exclusive pressure-sensitive vapor permeable adhesive technology. The adhesive has been proven to stick to almost all popular building substrates—performing in harsh conditions from hurricanes to sub-zero temperatures in Nome, Alaska.
Air Barrier Continuity and High Drying Capacity
With SlopeShield Plus SA properly connected to VaproShield’s WRB/AB wall membranes, a truly airtight and watertight building enclosure with high drying capacity can be achieved.
| Complete Roof and Wall Water Resistant, Vapor-Permeable Air Barrier System |
Combine SlopeShield Plus SA and VaproShield's WRB/Air Barrier membranes to create an airtight, watertight, BREATHABLE building enclosure; mitigating moisture damage and saving energy for the life of the building.
