What is Intumescent Fireproofing and Why You Need It
Intumescent fireproofing is a passive fire protection technique that involves applying a special coating to structural elements, such as steel, to provide fire resistance ratings of up to 4 hours. You can find this technique utilized in commercial, industrial, and residential buildings, as well as in offshore structures.
The primary purpose of intumescent fireproofing is to provide additional time for occupants to evacuate a building in the event of a fire emergency, as well as to minimize damage to the building’s structure.
Types of Intumescent Fireproofing
There are three common types of intumescent fireproofing coatings, each with its own unique formulation and application properties:
Water-based
At Global Fireproof Solutions, we utilize water-based coatings for intumescent fireproofing. These coatings are environmentally friendly and contain a high percentage of water. They are easy to apply, have low volatile organic compound emissions, and offer good adhesion to various substrates. This type of coating is suitable for indoor applications and is often used in commercial and residential buildings.
Solvent-based
Another form of intumescent fireproofing coating is solvent-based coatings which utilize organic solvents. They provide excellent adhesion and durability, making them suitable for outdoor applications and areas with high humidity or corrosive environments. However, solvent-based coatings have higher VOC content and require careful handling due to their flammability.
Epoxy-based
Epoxy-based coatings combine the fire protection properties of intumescent materials with the exceptional adhesion and chemical resistance of epoxy. These coatings are commonly used in industrial settings, such as petrochemical plants and offshore facilities, where fire protection and corrosion resistance are both critical.
How Intumescent Coating Works
The integral component behind intumescent fireproofing lies in the expansion and charring of the coating when exposed to heat. The coating typically consists of several layers: a primer, an intumescent layer, and a top coat. When the temperature rises during a fire, the intumescent layer undergoes a chemical reaction, releasing gas that causes it to swell and expand.
As the intumescent layer expands, it forms an insulating foam-like char that acts as a barrier, shielding the underlying material from the heat. This layer delays the transfer of heat to the structural element, thus extending the time it takes for the structure to reach critical temperature levels and lose its load-bearing capacity.
Benefits of Intumescent Fireproofing
By implementing intumescent coatings to your property, you enhance your structure’s fire resistance, boost its aesthetic versatility, preserve its structural integrity, and protect against corrosion. All of which keeps not only your property safe but yourself, your workers, and any other occupants that frequent your business.
