Vaproshield PanelShield SA
Description
The Vaproshield PanelShield SA is a high-performance breathable weather-resistant membrane designed to protect the building envelope while allowing moisture vapour to pass through freely. This advanced self-adhered water-resistive barrier (WRB) prevents air infiltration and liquid water penetration, ensuring long-term building integrity without compromising the wall system’s ability to dry.
Its aggressive adhesive firmly bonds to OSB, concrete and other common substrates, delivering a continuous and reliable seal. Unlike many alternatives, the Vaproshield PanelShield SA requires no primer thanks to its superior adhesive technology. It can be installed in all weather conditions, even in temperatures as low as 20°F (-6°C), making it ideal for year-round construction schedules.
This breathable weather-resistant membrane offers exceptional durability, withstanding up to 12 months of UV and weather exposure—perfect for long-term or phased projects. Designed with excellent drying capability at 26 perm, it ensures that trapped moisture is able to escape, preventing mold growth and structural damage.
Engineered for versatility, the Vaproshield PanelShield SA is suitable for use in transitions, rough openings, fenestrations, and full-wall applications. It passes ASTM E2178 and E2357 air barrier tests, meets Class A fire rating (ASTM E84), and contains zero VOCs or harmful toxins, making it a safe and environmentally friendly choice.
It’s tough polyester construction stands up to the demands of construction handling, both onsite and during transportation, without compromising performance. Backed by a 20-year warranty, this membrane provides lasting protection for both residential and commercial building projects.
For architects, builders, and contractors seeking a breathable weather-resistant membrane that combines durability, performance, and ease of installation, the Vaproshield PanelShield SA is a proven solution that ensures the building envelope remains airtight, watertight, and vapour-permeable for years to come.
