Firestopping
Materials and assemblies used to maintain required fire-resistance performance at penetrations or joints in rated construction.
Why it matters
The installed system must match its intended application. Generic foam or sealant is not proof that a penetration has been appropriately protected.
In practice
A project example
New cabling passes through a rated wall, requiring review of the penetration protection.
