Factory Mutual (FM) 4991 Approved Firestop Contractor
Factory Mutual has for the first time in history approved a contractor. In the past FM Global has only approved products. However, in the Firestopping industry application of the product alone will not prevent fire and smoke spread. The product must be installed according to manufacture and UL specifications resulting in a specific rated system. Realizing this FM found it necessary to approve both the firestopping product and the specialty contractor. Now by using an FM approved 4991 contractor you can be assured that all life safety needs will be meet with independent 3rd party tested systems.
GPI was in the first round of FM approved 4991 contractors showing our commitment to life safety excellence for almost 20 years.
The FM 4991 standard can be found here. The Firestopping 07840 specifications can be found here.
