BlockShield SA (3/8/2022)

VaproShield BlockShield SA is a self-adhered, non-asphaltic, durable, air, water, and vapor barrier membrane with an aggressive pressure-sensitive adhesive that does not require a primer and is easily applied to most construction substrates.  Designed for use in commercial and residential construction applications, BlockShield SA creates a barrier against water, air, and moisture infiltration when applied to a rainscreen assembly behind exterior cladding.

12-month UV and weather exposure makes membrane ideal for long-term projects.  BlockShield SA can be applied in virtually all weather conditions including below freezing, 10 degrees F and rising, without the use of primer.
