Our Envelope Sealant Systems
Sealing Buildings Where They Fail First
EnvelopeGuard is a next-generation elastomeric co-polymer sealant designed to create an airtight and watertight seal at the most critical points of the building envelope. – windows, doors,
Applied as a liquid, EnvelopeGuard forms a continuous bond across multiple surfaces, sealing gaps, transitions, and penetrations before they become failure points. Once in place, the system is built to move with the structure and hold its performance over time as a long-lasting seal that protects the building envelope from day one.

Engineered to Outperform Traditional Sealants
Most sealants are designed as a quick fix. They shrink, crack, or pull away over time, especially under pressure from weather, movement, and temperature swings. Envelope Guard is built differently, creating a continuous, flexible seal that holds where traditional methods fail.
Applies and cures in hot, cold, and damp conditions for year-round building
Forms a seamless, monolithic barrier instead of beads that break down
Bonds across multiple surfaces with consistent, long-term adhesion
Stays flexible through movement, temperature swings, and pressure changes
Helps reduce air leaks and prevent moisture intrusion at critical points
