Flashing
VaproShield® has introduced BlockFlashing, a self-adhered, non-asphaltic, durable, air, water, and vapor barrier flashing with an aggressive pressure-sensitive adhesive that does not require a primer and is easily applied to most construction substrates.
BlockFlashing is designed for use as a rough opening flashing or transition flashing providing a barrier against water, air, and moisture infiltration. Compatible with many building sealants, BlockFlashing has no adverse reaction with synthetic rubber, butyl, polyurethane, silicone, and silane terminated hybrid sealants.
