Asmaco Firestop Silicone Sealant is a premium-grade, one-part, neutral-cure silicone sealant formulated to provide reliable fire-resistant sealing in construction joints and service penetrations. It creates a durable and flexible barrier that resists the passage of fire, smoke, and gases, ensuring enhanced safety and compliance with fire protection standards.
Specially developed for use in fire-rated wall and floor assemblies, Asmaco Firestop Silicone maintains its integrity under extreme temperatures and movement conditions. Its excellent adhesion to a wide variety of construction materials — including concrete, glass, metal, brick, and ceramics — makes it ideal for both new installations and maintenance applications.
Once cured, the sealant forms a tough, elastomeric joint that remains flexible, waterproof, and weather-resistant, offering both fire protection and long-term durability in interior and exterior environments.
