ENVIRO-BARRIER&trade; is a single component, fluid applied, elastomeric membrane to provide an air, water and vapor barrier when applied to above grade wall assemblies. It cures to form a resilient, monolithic, fully adhered elastomeric membrane which resists air leakage and water penetration plus acts as a vapor barrier. Complies with NFPA 285 in various wall assemblies. &nbsp;
<ul>
<li>Remains flexible over a wide temperature range</li>
<li>Meets and exceeds highest industry standards for air barrier performance</li>
<li>Cost effective easy spray application</li>
<li>Asphalt-free formulation</li>
<li>Excellent adhesion to most construction materials such as exterior gypsum board, CMU, concrete, stone, wood and metal.</li>
</ul>
PACKAGING: ENVIRO-BARRIER&trade; comes in 5 gallon pails and 55 gallon drums.

ENVIRO-BARRIER™ STPE is a moisture-curing, single-component, fluid-applied air and water-resistive barrier for above-grade wall assemblies. Its vapor-permeable, silyl-terminated polyether formulation creates a durable, seamless membrane that controls air leakage and liquid-water intrusion while allowing moisture vapor to pass through the assembly.Applied in a single coat by spray, roller, or brush, ENVIRO-BARRIER STPE adheres to a wide range of common construction substrates, including concrete, CMU, gypsum sheathing, rigid foam insulation, plywood, OSB, steel, copper, and aluminum. The non-asphaltic membrane develops rain resistance in less than 30 minutes, withstands up to 12 months of UV exposure, remains flexible at temperatures as low as -20°F (-28.9°C), bridges substrate cracks, and self-seals around nails and other fasteners. With 99% solids, low VOC content, and no phthalates or isocyanates, it provides a high-performance solution for cavity-wall and masonry-wall systems in new construction and retrofit applications.<ul><li>Fluid-applied, vapor-permeable air and water barrier</li><li>Creates a durable, seamless membrane in a single coat</li><li>Rain resistant in less than 30 minutes</li><li>Applied by spray, roller, or brush</li><li>Up to 12 months of UV exposure</li><li>Remains flexible, bridges cracks, and self-seals around fasteners</li><li>Strong adhesion to damp and dry substrates</li><li>Class A rating in accordance with ASTM E84</li><li>Low-VOC formula with no phthalates or isocyanates</li></ul>COVERAGE:<ul><li>Gypsum, OSB, Plywood&nbsp;- 80 ft.2/gal.
