Why Choose Grace Vapor Permeable Products?

Grace Permeable products prevent damage to the interior building structure. Specially formulated to prevent air and liquid water infiltration while allowing for the passage of water vapor, Grace barriers are breathable. This allows water vapor that would otherwise condense a means of escape. Grace vapor-permeable products provide:

    • Waterproofing
      Grace vapor-permeable barriers guard against the infiltration of moisture-laden air, preventing it from building up within the wall cavity where it can degrade building materials.
    • Increased Building Durability
      Grace vapor-permeable products provide effective protection against moisture-related structural issues.
    • Improved Indoor Air Quality
      Controlling the influx of moisture-laden air through the building envelope guards the interior against mildew and mold issues that can affect air quality, food sources, furnishings, and structural components.
    • Enhanced Energy Efficiency
      Grace air barriers prevent air leakage that plays a significant role in temperature fluctuations, reducing the need for heating, ventilation, and air conditioning. According to an NIST (National Institute of Standards and Technology) study, this can dramatically reduce energy costs up to 39%.
  • Which Grace Air & Vapor Products Are Right for Your Project?

    Procoat Systems offers the full Grace vapor permeable-barrier product line:

    • Perm-A-Barrier VP
      This single-component, fluid-applied air barrier forms an acrylic membrane which, once cured, provides a strong, durable, fully-bonded elastomeric (rubber-like) sheet. Guarding against the damaging effects of air and liquid water infiltration, as well as air exfiltration, Perm-A-Barrier VP minimizes condensation issues and energy loss.
    • Perm-A-Barrier Liquid
      This two-component, fluid-applied air and vapor barrier protects above grade wall assemblies from air, vapor, and water infiltration. The resulting barrier of cold-vulcanized, synthetic rubber prevents air infiltration and exfiltration while preventing condensation issues and energy loss. An excellent choice for use in detailed areas.
    • Perm-A-Barrier Wall Membrane (Self-Adhering Sheets)
      This tough, self-adhering, self-sealing waterproofing membrane features 0.9mm of rubberized asphalt bonded to 0.1mm high-density, cross-laminated polyethylene film. Applied on concrete, masonry, wood, and gypsum wall surfaces, it provides a cost-effective, virtually-impermeable air, vapor, and water barrier, forming a continuous structural seal.

  • Grace Permeable Membrane Advantages

    • Seamless, Airtight Protection
      Protects against the damaging effects of air infiltration and exfiltration, forming a continuous membrane with no lapse.
    • Guards Against Moisture Damage
      Prevents liquid infiltration while allowing water vapor to escape, providing long-term protection from the effects of moisture trapped in the building structure.
    • Primer-less
      Easily applied with minimal surface prep.
    • Quick & Easy Application
      Apply by airless spray in temperatures as low as -20°F.
    • Versatile
      Easy to work with in tight spaces such as internal/external corners, brick ties, penetrations, and more, providing continuous air barrier protection.
    • Fully-Bonds to Substrate
      Forming a strong, durable, lasting coating for an effective air barrier.
    • Asphalt-Free & Cold-Tolerant
      Will not get brittle over time, retaining flexibility to -23°F.
    • No Product Loss
      Wet thickness = dry thickness.
    • Flexible
      Elastomeric (rubber-like) formulation accommodates minor structural movements with ease, bridging cracks.
    • Moisture-Tolerant
      Can be applied to surfaces that are damp to the touch.
    • UV Tolerant
      Grace permeable membranes can stand up to UV exposure up to 60-days.
