Cementitious Fireproofing

Eco Spray Insulation - Cementitious Fireproofing


What is Fireproofing?

Fireproofing is now a must for family properties and commercial buildings. Even in cases where the building is made from metal, fireproofing shouldn’t be ignored. it’ll keep you safe just in case of fireside and it is a coat to stop electrical circuits from overheating.

There are several methods available to builders and designers to think about fire prevention. Active fireproofing (AFP) refers to installing equipment that is triggered by an action like a system or extinguisher.

Passive fireproofing (PFP) may be a relevant safeguard measure to be considered from the initial stages of construction and is implemented within the design elements. By using the proper system, the spread of fireside and smoke are often prevented successfully leading to ample time for evacuation and therefore the appropriate protocols to be executed. Some examples are fire doors, room compartmentalization, and therefore the installation of the fire-resistant coating.

Cementitious Fireproofing

The cementitious products are the foremost common materials used for fireproofing services. it’s one component, spray applied, mill-mixed plaster designed to guard the structural foundation of the building from falling. This will be applied to concealed and exposed steel structures.

Though labor does have the potential to approach the value of those jobs, since they need to be applied in several, successive layers, they’re still well-suited for dry environments where the substrate isn’t expected to be exposed to heavy vibrations and/or impact.

Products are often applied to steel and concrete substrates. They form a consistent base, solid bond and dust-free surface providing exceptional performance with a high yield capability and sturdiness . The chosen products are tested and authorized to the very best industry standards.

Fireproofing is formed from common ingredients that are tested and suggested by the building industry, including Monokote MK-6, Cafco Blaze Shield, and Cafco 300. These materials are combined chemically like lime, mica, fibrous plasters, and other combinations to hurry up hardening. It doesn’t include asbestos and it’s safe to use in homes and commercial buildings.

Types of Cementitious Fireproofing

Standard-Density Cementitious Fireproofing:

The standard-density fireproofing has the below-listed qualities, and it’s appropriate to use in locations that aren’t subject to physical contact or abuse.

Benefits of ordinary Density Cementitious Fireproofing:

  • No Flame Spread or Smoke Developed
  • It is established as non-combustible
  • Standard-density is quite a minimum of 15 PCF (240kg/m2)
  • No cracking, spalling, or delamination
  • Compression shall be quite 16.25 lbf/in2 (112 kPa)
  • Erosion shall be 0.00 gr/sq.ft. maximum
  • There is no evidence of corrosion allowed
  • There is no evidence of mold growth

Medium-Density Cementitious Fireproofing

For exposed applications of sprayed fire-resistive materials, manufacturers got to suit standards and therefore the products need to fulfill the materials and composition requirements alongside the minimum physical properties as per ASTM regulations.

Exposed fire protection shall include, but aren’t limited to the subsequent areas:

  • Stairwell columns and beams
  • Elevator shafts steel
  • Mechanical room columns
  • Areas where physical abuse could also be encountered

High-Density Cementitious Fireproofing:

High-density fire protection shall be defined as permanently exposed to weather, and shall be manufactured of cement-based products, with lightweight aggregate, with a minimum density of 40 PCF, and can got to abide to the subsequent requirements as per ASTM:

  • No Flame Spread or Smoke Developed
  • It is established as non-combustible
  • No cracking, spalling, or delamination
  • Compression shall be quite 350 psi (2411 kPa)
  • Erosion shall be 0.00 gr/sq.ft.
  • No evidence of corrosion
  • No evidence of mold growth

Why use fireproofing technology?

For a certain amount of time-or grouping, fireproofing preserves the steel frame. In other words, fireproofing is the protection applied to the steel from high heat, maintaining the structure’s strength and durability. 

Structure stability is highly important since you, the occupant, need time to evacuate and it takes time for the first responders to arrive. Obviously, what’s at risk here is the lives of people.

Gypsum Based Fireproofing

The gypsum-based cement fireproofing material for structural steel framed construction is fire resistive material. This material is a dry, fire-resistant material that forms a slurry mix when combined with water, which is then spray-applied to the substrate to allow an application that matches the substrate’s contours. The substance is applied to steel structures inside or outside but is not recommended for long-term weather exposure. Together with an Accelerator, the gypsum-based fireproofing product can be used to ensure that set time and product yield are lower for lower installation costs.

Gypsum Related Fireproofing Advantages:

  1. Spray for Fireproofing 
  2. Increases the performance of applicators due to fast and reliable applications 
  3. Provides scores of up to 4 hours of fire resistance 
  4. Checked for UL fire and inspected the factory 
  5. Resists from air erosion and abrasion damage 
  6. No mineral fibers contain gypsum-based formulations 
  7. No need for a topcoat or surface sealer

Thermal Barrier Fireproofing

The fireproofing material of the thermal barrier is built to protect spray foam insulation from fire and heat effects. The substance is sprayed over the foam insulation because of the properties of this material, resulting in a tight, monolithic coating that adheres to the SPF. The thermal barrier product is intended to be applied to walls and ceilings indoors. Together with the Compressor, this product can also be used to ensure that set time and product yield for lower installation costs are lower. 

Benefits of Fireproofing Thermal Barrier:

  1. Extremely robust to withstand heat and fire effects 
  2. Resistant to Humidity 
  3. Economical-low application-related costs 
  4. Checked for UL fire and inspected factory

Cementitious or intumescent coatings?

In the thick concrete that was mostly used to fireproof manufacturing facilities until about the mid-twentieth century, lightweight cement coatings have their roots. Dense concrete, inexpensive and resistant even to very high temperatures, was gradually replaced by cement coatings that were not quite as heavy (and thus cheaper and easier to apply) once the technology had been developed. 

Cementitious coatings today remain relatively inexpensive materials for installation fireproofing. While labor has the potential to push up the cost of these workers, since they may be used in many successive layers, they are still well-suited for dry environments where strong vibrations and/or impact are not likely to be exposed to the substrate. 

In conditions with high atmospheric moisture levels where they should not be used, cementitious coatings will eventually create a void between the substrate and the coating itself. This room is suitable to settle for moisture and to set in for the corrosion process under fireproofing (CUF). Intumescent coatings work, however, on a different principle. Instead of creating a relatively dense physical barrier between the flames and the steel, when exposed to intense heat, they shield intumescents, or char and expand, as cementitious coatings do. Literally, the coating grows as a means of creating the sort of barrier maintained by cement coatings irrespective of temperature. Intumescents delay the heating of steel and prolong the potential response time until a major failure or collapse occurs by rising in volume and decreasing in density.
