Complete Building Envelope System

VS WrapShield Wall 2

VS Wall A

WrapFlashing SA™ Self-Adhered in conjunction with: VaproLiqui-Flash™, Vapro-SS Flashing™ and/or VaproBond™ for rough opening and penetration flashings.

VS Wall B

A rainscreen system provides multiple benefits:

  • Initial water barrier
  • Vented cavity for pressure equalization that serves as a capillary break
  • Drainage for liquid water transport, away from the structure

VaproShield offers VaproMat™ or VaproShim SA™ Self-Adhered to create a unimpeded vertical drainage cavity or rain screen system. 


WrapShield SA Self-Adhered WRB/Air Barrier membrane protects the building envelope by allowing vapor pass through (breathable) but not air or liquid water, mitigating costly moisture damage and saving energy for the life of the building.

Basic Use

WrapShield SA Self-Adhered is installed above grade behind rain screen wall cladding assemblies.


WrapShield SA Self-Adhered consists of multiple layers of spun-bonded polypropylene fabric with a proprietary, fully self-adhered pressure sensitive adhesive that allows for initial re-positioning prior to rolling.


Superior Building Envelope Protection

  • High drying capacity (50 perms) allows building materials to dry-out, reducing the risk of damage from moisture infiltration, mold, mildew and rot for the life of the building.
  • Air tight barrier – stops air infiltration as per the ASTM 2357 Air Barrier assembly test, ABAA approved.
  • Consistent millage thickness – factory made rolled good ensures consistent properties and performance.
  • Fully tested building envelope system – rough opening flashing accessories eliminate the need for untested outside components.
  • Emits zero VOCs, contains no Red List Chemicals, ensuring crew safety and a healthy building.
  • Warranty - 20 year material warranty is available

Cost Advantage

  • Fully bonds without primer to most substrates (excluding OSB), eliminating costly delays due to primer application restrictions
  • Applies directly to a clean and dry to-the-touch substrate, no additional substrate preparation is required
  • Reduces contractor liability by using fully tested VaproShield flashing system: single source membranes, flashings and sealants
  • Long-term durability, standard 20 year material warranty
  • Optimizes substrate coverage, using 95% net of sheet good

Phase Construction Friendly

  • Simple installation – requires only basic tools, no specialized mobilizations or protection gear are required.
  • Ease of installation - vertical or horizontal application
  • Apply to clean and dry-to-the-touch “as new” substrates, no additional preparation is required.
  • Spans substrate joint gaps up to 7/8” (22.2mm), eliminates need for tapes and fillers.
  • Installs in below freezing temperatures 20°F (-6°C)
  • Sustains up to 180 days UV and climate exposure prior to cladding installation.
