Spray Applied Fireproofing Contractor Serving Iowa
Spray Applied Fireproofing Material (SFRM) is a gypsum or portland based, dry material that is mixed onsite with water and then sprayed onto structural steel and decks in primarily commercial applications. It is designed to “insulate” the structure of a building, preventing the steel structure from getting too hot, as steel will lose half its strength once it reaches approximately 1,000 degrees Fahrenheit.
Fireproofing and Firestopping Are Two Different Applications
Note that there is a distinct difference between fireproofing and firestopping. It’s important to know the difference, as it can impact the safety of your building and its occupants.
Fireproofing
Fireproofing is designed to slow the risk of the structure from collapsing, giving occupants time to escape and Firefighter’s time to fight the fire.
Firestopping
Firestopping is used to seal top of wall and penetrations between walls and floors to stop the spread of smoke and fire.
Spray Applied Fireproofing Properties
Spray Applied Fireproofing is designed to provide critical fire resistance to structural elements through a combination of physical properties such as density, bond strength, and application thickness. It is applied in varying thicknesses depending on the required fire-resistance rating and the size or type of steel being protected, typically ranging from 3/8” to over 2”. These properties work together to ensure the material adheres effectively, performs under fire conditions, and meets building code requirements for safety and durability.
Density
In SFRM (Spray Applied Fireproofing Material), density is a critical property that influences both fire resistance and durability. Low-density SFRMs are commonly used in concealed areas, while medium to high-density SFRMs are suited for areas exposed to mechanical damage or high humidity due to their increased toughness and moisture resistance.
Bond Strength
For SFRM, bond strength measures how effectively the material adheres to structural elements like steel beams and decks. Adequate bond strength is essential to prevent delamination or dislodgement during construction activities, thermal expansion, or seismic movement, and it must meet minimum standards set by testing agencies such as ASTM E736.
Application Thickness
The required application thickness of SFRM is determined by fire resistance ratings, which are based on standardized fire tests like ASTM E119. Thickness varies depending on factors such as steel size, type of SFRM, and desired fire rating, with thicker applications needed for larger structural members or higher fire endurance.

Benefits of Spray Applied Fireproofing Material
Spray Applied Fireproofing Material provides essential fire resistance to structural elements in commercial and industrial buildings. Its many benefits make it a popular choice for fireproofing contractors and builders looking to enhance safety, efficiency, and cost-effectiveness. Just a few of the benefits of Spray Applied Fireproofing Material include:
Easy and Efficient Application
Spray Applied Fireproofing is designed for fast and efficient installation using spray equipment, which allows large areas to be covered quickly. Its ease of application reduces labor time and minimizes disruptions on construction sites, making it ideal for both new builds and retrofits.
Cost-Effective
SFRM offers a cost-effective solution for enhancing building fire protection. With low material and labor costs compared to alternative fireproofing methods, Spray Applied Fireproofing is ideal for large-scale projects seeking budget-friendly fire resistance without compromising safety or performance.
Lightweight
Spray Applied Fireproofing adds minimal load to structural elements. This lightweight nature makes it suitable for high-rise buildings and structures where minimizing additional weight is critical.
Versatile
Spray Applied Fireproofing Material can be applied to a wide range of substrates, including steel, concrete, and composite members. Its adaptability makes it suitable for different project types, from industrial facilities to commercial and residential buildings.
Code Compliant
SFRM products are rigorously tested to meet industry standards such as ASTM E119 for fire resistance and ASTM E736 for bond strength. Their compliance with building codes and fire safety regulations ensures they provide certified protection in accordance with local and national requirements.
Spray Applied Fireproofing Frequently Asked Questions (FAQ)
The following are a few questions we typically hear regarding spray applied fireproofing. If you have any questions, feel free to contact our fireproofing contractors.
Does Spray Applied Fireproofing require maintenance?
Generally, SFRM is low maintenance. However, it should be inspected regularly for damage, especially in high traffic or exposed areas, and repaired as needed to maintain its fire resistance rating.
Is SFRM environmentally friendly?
SFRM can be environmentally friendly. Many modern SFRM products are formulated with low VOCs and non-toxic ingredients, making them safe for use in occupied buildings and environmentally responsible construction.
