Simplifying Firestop Safety at Every Job.
Firestopping is all about containment. Firewalls and rated floors are designed to stop the spread of fire, smoke, and toxic gases. Any time a fire rated substrate is interrupted (or penetrated) the rating is taken away. As firestop installers, we are charged with restoring the integrity back to fire rated substrates (i.e. walls, floors, and occasionally roofs). Firestopping uses specific tested and proven assemblies to restore the substrate rating. These assemblies are commonly known as UL Systems.
The majority of our work is related to installing UL Systems applicable to MEP penetrations through gypsum walls and concrete floors. We also commonly install fire caulking systems at the top and bottom of gypsum or block/concrete walls to ensure transmission resistance of smoke & toxic gases. We also install fire barriers at the edge of slab on multi-story buildings with bypass situations such as Curtain Wall.
Some of the services provided by Darragh Construction Services include:
Penetration Firestopping in Fire & Smoke Walls
Top & Bottom of Wall Firestopping & Smoke Sealing
Edge of Slab Firestopping
In-Wall Fire & Smoke Seals at bypass conditions at rated roof assemblies

We are also able to work with firestop engineers to provide assistance for issues that don’t comply with any specific UL Designs.
