Firestopping, Joint Protection and Perimeter Fire Containment Testing

Fostering confidence and security in the safety and performance of fire-resistant rated designs.

Fire safety joint protection construction


Firestopping, joint protection and perimeter fire barriers are designed to limit flame and smoke spread through penetrations in a fire-rated wall, floor, and ceiling assembly; joints; and barriers offer the needed protection to keep the building structure and its occupants safer.   

They are designed to meet fire and smoke safety and environmental sustainability requirements and expectations. We understand these challenges. We provide training, advisory, testing, Verification, inspection, and certification solutions for firestopping systems and designs to help manufacturers get compliant products to the market quickly. We identify qualified firestop contractors, who install firestopping systems. We also serve building owners to assist in technical assessment, inspections, commissioning and forensics to help ensure the exterior wall assembly meets expectations.   


Our services provide trust in the compliance, performance, reliability, security, durability and sustainability of fire resistant rated designs.   

We certify fire-resistance-rated firestopping, joint projection and perimeter fire barriers to safeguard against the spread of fire and smoke within a building and the spread of fire to or from the building. Barrier designs are tested to international standards to establish an hourly rating to provide evidence of compliance to code requirements. Suitable fire-resistance-rated systems can be identified by using our Product iQ powerful search tool.
