Soudal Firecryl FR - Fire-Rated Acrylic SealantSoudal Firecryl FR

Fire-Rated Acrylic Sealant for Passive Fire Protection

Soudal Firecryl FR is a high-performance, fire-resistant acrylic sealant designed to maintain the integrity of fire-rated walls and floors by sealing joints and gaps against the spread of smoke and flames. When exposed to fire, it swells to form a char that blocks fire and smoke penetration. Ideal for linear joints, service penetrations, and connection joints in fire-rated partitions and construction elements.

• Permanently Flexible: Accommodates joint movement while maintaining fire protection.
