TremGlaze Flex Foam is a flexible, low-expansion polyurethane foam designed to seal gaps and joints while accommodating movement within the building assembly. It creates a durable air and moisture seal and is ideal for window and door perimeters, penetrations, transitions, and other areas requiring an expanding foam seal.

Its flexible formulation helps maintain the seal as building components expand, contract, and move over time.
