What is Fire Retardant Wood Treated With

When it comes to building and construction, ensuring the safety and resilience of structures is of utmost importance. One crucial aspect of this is fire safety, and one method used to enhance the fire resistance of wood is through treatment with fire retardants. In this article, we’ll delve into what fire retardant wood is treated with and how it works to protect the wood from fire damage.

What are Fire Retardants?

Fire retardants are substances that are applied to materials, including wood, to reduce their flammability and delay the spread of fire. They can be classified into several types based on their mode of action, including physical action, chemical action, or a combination of both. When it comes to wood, fire retardants work by either forming a protective char layer on the wood’s surface or by inhibiting the chemical reactions that occur during combustion.

Common Fire Retardants for Wood

There are several chemicals that are commonly used as fire retardants for wood treatment. These include:

Chemical Mode of Action
Ammonium Phosphate Chemical action – acts as a heat sink and releases water vapor to dilute flammable gases.
Ammonium Sulfate Chemical action – releases water vapor and ammonia gas to dilute flammable gases.
Borates Chemical action – disrupts the combustion process by releasing water and carbon dioxide and forming a protective char layer.
Phosphate-based Compounds Chemical action – release water vapor and phosphoric acid, diluting flammable gases and forming a protective char layer.

How Fire Retardant Wood Treatment Works

When wood is treated with fire retardants, the chemicals penetrate the wood and become an integral part of its structure. In the event of a fire, these chemicals are activated and work to prevent or slow down the combustion process. For example, substances like borates release water vapor and carbon dioxide when exposed to heat, effectively diluting the flammable gases and forming a protective layer of char that insulates the wood and slows down the spread of flames.

Benefits of Fire Retardant Wood

Using fire retardant treated wood in construction and building projects offers several advantages:

  • Improved fire safety: The primary benefit is the enhanced fire resistance of structures, reducing the risk of fire damage.
  • Compliance with building codes: Many building codes and regulations require the use of fire retardant materials in certain applications.
  • Longevity: Fire retardant treatment can extend the lifespan of wood by protecting it from fire and decay.
  • Versatility: Treated wood can be used in a variety of indoor and outdoor applications, expanding its usability.
  • Peace of mind: Using fire retardant wood provides peace of mind for occupants and property owners, knowing that the structures are better protected against fire hazards.
