Sealants and Firestop Solutions

In a battle against fire, every second counts. That’s especially true if openings exist between adjacent rooms or floors within a building, such as those made to accommodate pipe, conduit, ducts and cables. Such pathways for voice, data, video, power, plumbing and ventilation can quickly become pathways for fire.

The good news is, it doesn’t take much to inhibit the spread of fire before it begins. For approximately 1/100th of the cost of constructing a building, you can install a building-wide Nelson Firestop Systems. Should a fire ever break out, that small investment will help contain it. The spreading that could occur in minutes will be delayed for hours giving fire-fighting personnel the critical time they need to extinguish the blaze, avert devastation and, in some cases, save lives.

That’s what firestopping should do. What it will do, however, depends on whether or not you have the right products in the right places. No one ever intentionally creates a poor firestop installation, but the selection process frequently yields an incorrect seal.

Solving a complex problem.

Making the right firestopping choice for a wall or floor penetration is not a simple matter. There is far more to the decision than the size of the hole. Establishing a reliable firestop seal depends on no less than eleven criteria:

  • Type of barrier being penetrated (wall or floor)
  • Thickness of barrier
  • Barrier construction (masonry or gypsum)
  • Fire rating of barrier (1, 2, 3 or 4-hour)
  • Type of penetrating item (pipe, cable, conduit, etc.)
  • Construction of penetrating item (plastic, steel, copper, etc.)
  • Size of penetrating item, and how many of each
  • Type and thickness of insulation (if any)
  • Shape of opening
  • Size of opening
  • Annular space between penetrating item and inside wall of penetration

Nelson Firestop composite sheets are used to seal penetrations and maintain the rating of fire rated floors or walls. Suited for cable tray penetrations, large floor or wall openings, and other cable systems they are available in a variety of sizes
Nelson Firestop FSC cable coating, FSC3 joint coating and CMP compound are all used to provide a fire protective coating for cables, floor and other areas needing sealing
Nelson Firestop Putty (FSP) is easy to install putty that inhibits the passage of smoke and flame through penetrations and joints

Nelson Firestop MPS multi-plug system is a fire rated, environmental cable sealing system with molded Tecron rubber plugs for use in pipe sleeves or cast round openings. provides protection from fire, smoke, water and blast pressures
Nelson Firestop pipe choke system (PCS) is designed to expand to seal voids created from fire exposure to penetrations of combustible pipes. It is maintains the rating of fire rated floors and walls
Nelson Firestop PLW pillows and fire bricks are used for cable, cable tray and other penetrations or for temporary firestop closures by preventing the penetration of fire
