Fireproofing: Cementitious
(SFRM – Spray Fire Resistive Materials)

Fires are one of the biggest dangers to your home or business. If you don’t have any kind of fireproofing applied around the commercial spray foam or residential spray foam in your building, what starts as a small flame could have catastrophic consequences.

Don’t let a fire put you, your family, or your employees in danger. Choose to have SPFM Spray Foam Insulation install cementitious fireproofing spray along with your commercial spray foam or residential spray foam, a fire-resistant material that can stop the spread of fire and prevent disaster.


What Is Cementitious Fireproofing?

Cementitious fireproofing is a type of spray that’s fire resistive. While it’s made primarily of concrete, it can also contain the following materials:

  • Vermiculite
  • Perlite
  • Mineral wool
  • Quartz

Cementitious fireproofing is typically sprayed alongside commercial spray foam or residential spray foam to keep the interior structures of a building safe.

When used with commercial spray foam or residential spray foam, cementitious fireproofing has three distinct properties depending on your needs:

  • Density – Low density is best for fast coverage at a lower price. Medium density is more resilient to air movement and contact. High density is the superior product and works best for parking garages and mechanical rooms.
  • Bond strength – A bond strength of 150 psf is good for using with residential spray foam in a non-high-rise building. A bond strength of 430 psf is good for a high-rise building with commercial spray foam up to 420 feet. A bond strength of 1,000 psf is ideal for pairing with commercial spray foam in buildings over 420 feet.
  • Thickness – Thickness can vary and is usually customized depending on the exact structures being protected.


How Cementitious Fireproofing Can Stop a Fire

With the help of cementitious spray paired with your commercial spray foam or residential spray foam, you can drastically slow down the spread of flames. It’s a passive method of fireproofing that you should have installed with your commercial spray foam or residential spray foam insulation.

It will protect the steel and concrete structures in the building from melting or breaking down by thermally insulating them. For example, it might protect:

  • Steel joists
  • Metal decking
  • Columns
  • Beams


What Are the Benefits of Cementitious Fireproofing?

By having cementitious fireproofing sprayed when you’re having commercial spray foam or residential spray foam installed, you can keep your building safe. In addition to pairing perfectly with commercial spray foam or residential spray foam, it also provides additional benefits, such as:

  • Low Cost Compared to Intumescent Fireproof Coatings
  • Great Adhesion to Closed Cell Spray Foam
    Little to no maintenance
  • Acoustical treatment for exposed areas
  • Controls condensation to prevent water damage


What Are the Disadvantages of Cementitious Fireproofing?

Cementitious Fireproofing is a great low cost durable fire-resistant material for most applications but it does have its disadvantages in areas with high moisture, High Traffic, or in locations where visual appearance of the surface is important.

  • Not suitable for high traffic areas or locations where it can be touched or disturbed.
  • Not suitable for applications with high moisture or humidity levels or areas that come in contact with water
  • Not suitable for areas where visual appearance and aesthetics of the protected surface is important Intumescent Fireproofing being sprayed
  • Does not create a smooth paintable surface

“Paint-like” Spray On Intumescent Fireprotecive Coatings
