All About Firestop Uses: A Detailed Guide

Any building manager or owner understands the value of a good firestop system. It prevents the spread of fire and smoke, protecting a building and the occupants inside. To keep passive fire protection systems functioning properly and prevent fire and smoke from spreading, fire-stopping is the application of fire-resistant sealants. Fire resistance protection must be taken into account during the design and installation of a new industrial partition or fire-rated space. Here is some additional information on the functions of the components of a firestop system.

What is a Firestop?

Firestops are physical barriers created to stop the spread of fire, toxic smoke, dangerous gases, and flames through gaps made during building renovations and the installation of grease ducts, electrical, communication, plumbing, and ventilation systems. It is important to keep commercial buildings and the people inside them safe since they are frequently busy locations where people come and go. This is especially important because these surroundings frequently lend themselves to fire-related dangers.

Unlike the caulk used to seal doors and windows, firestop materials have been tested and found to be effective by Omega Laboratory or Underwriters Laboratories (UL).

Firestop Materials

There are numerous varieties of firestop materials, each created to satisfy certain needs. Typically, silicones, mineral fibers, rubbers, intumescents, or cementitious mortars are used to make firestops. Regardless of the type of material, all firestops must undergo testing and approval by either Omega Laboratory or Underwriters Laboratories®. These facts and the test rating will be listed on the labels of firestop products.

  • Penetration sealants

Firestops that completely cover and seal the area around pipes, conduits, ductwork, and other metallic objects that pass through a fire barrier

  • Pipe collars

Non-metallic objects that pass through a fire barrier are surrounded by intumescent firestops.

  • Pass-through devices

As conduits, pipes, and other penetrants are added and withdrawn, self-adjusting intumescent firestop wires can be used.

  • Sleeves

Sleeves Firestops are created to be removed and used with cables easily, and they often come with intumescent putty.

  • Composite sheets

Large sheets of intumescent firestops are frequently used to close off bigger, disused holes, such as ventilation vents.

  • Cast-in devices

Firestops were put into the building where expected penetrations

  • Firestop pillows

Intumescent firestops are frequently utilized to replace firestop seals around new pipes, wires, and ventilation systems.

FireStop Components

Each component utilized to create a system must fulfill specific design requirements set forth by organizations. Let’s check out.

  • Slab Edge

A property’s perimeter slab edge is where smoke and fire tend to spread between rooms the most. The fire-resistance rating of a floor slab is extended by the slab edge firestop.

  • Curtain Wall

A thin wall with an aluminum frame is known as a curtain wall. The wall has inserts made of glass, tiny stones, or metal panels.

  • Top of Wall

There is a little opening at the top of a wall assembly and floor assembly that can let smoke and fire pass across rooms and floors. To inhibit the spread of fire and smoke, top-of-wall fire-stopping buxic covers these openings with a fireproof substance.

  • Joint

The joint where the wall and floor assemblies meet is safeguarded by joint fire stopping.


The fire-rated walls, partitions, floors, or ceilings that are being pierced; the cables, cable trays, or conduits that make up the object causing the penetration; and fire-stopping materials.

The installation of fire-stopping by qualified specialists is essential naasongs.net for ensuring that the system may be given a rating of up to four hours of fire protection because it is an important factor in fire prevention.
