Enershield-HP - Vapor Permeable Air/Water-Resistive Barrier Membrane

What is Enershield-HP?

Enershield-HP is a one-component, fluid-applied vapor permeable air/water-resistive barrier based on Silica Fortified RubberTM chemistry. This waterproof, resilient coating may be spray-, roller-, brush-, or trowelapplied directly to approved above grade wall substrates. It provides excellent secondary moisture protection behind wall claddings including brick, siding, metal panels, EIFS and stucco. A slipsheet is required for stucco claddings.
