Superior All-In-One Protection

Your Home's Worst Enemy: Moisture Infiltration


Windows Are The Most Vulnerable

In 2016 a new Texas home suffered extensive moisture damage prior to occupancy - “the windows were suspected to be a contributing factor,” notes the remediation consultant, typically due to “inadequate weather barrier and window detailing.”

Insufficient Drainage In The Wall Cavity

The stucco system on this $4 million home failed to have casing beads, sweeps, control joints, corner trims, drips, flashings, and a bond break resulting in massive deterioration and biological growth within 12 months.


All-In-One Protection

VaproShield’s water resistive barriers protect the wall cavity from moisture infiltration and breathe, allowing moisture to escape.

7. Immediately spread until all surfaces are completely covered and substrate below is no longer visible (approximately 30-45 wet mils (0.76-1.14mm)).

8. Allow VaproBond to set, then inspect for voids and apply additional VaproBond as needed to achieve complete coverage. RO is now ready for window and head flashing installation (by others).

Highly Advanced Roofing Underlayment

SlopeShield 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.

VPPCT Gold Badge

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 Advancement

VaproShield’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: 

  • Watertight
  • Vapor permeable, promoting long term drying of the roofing assembly through vapor diffusion
  • Tough and slip resistant
  • Foot traffic friendly
  • 180 days exposure prior to roof system installation

TraditionalPeelStick 2 101819

Traditional roof underlayments can trap moisture, degrading insulation performance and even simulating a leaking roof due to excessive condensation accumulation.

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 Breathe

By 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.

 

Installation in Less than Ideal Conditions

Installation crews can install SlopeShield Plus SA in less than ideal weather conditions. The surface must be dry-to-the-touch, but moisture content of the underlying materials can be high because the high drying capacity of
SlopeShield Plus SA allows moisture to dry through the process of diffusion, which occurs in the absence of any airflow. SlopeShield Plus SA can be installed in below freezing temperatures and sustains up to 180 days of UV and climate exposure prior to roof system installation.

Black Coloration Intentional

The dull black color of SlopeShield Plus SA absorbs heat from the sun while exposed, accelerating the drying process of wet sheathing and insulation

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.
