What is Fire Resistant Decking? [Pros & Cons]

Fire accidents can have devastating consequences, especially when they occur in residential areas. One area of concern is the deck, which is susceptible to fire hazards. In this blog article, we will explore the concept of fire-resistant decking and discuss its importance in ensuring safety. We will delve into what fire-resistant decking is, the main characteristics of fire-resisting materials, how to make a deck fire-resistant, and the criteria for evaluating fire resistance.

What is Fire-Resistant Decking?

Fire-resistant decking refers to materials and construction techniques that are designed to withstand and inhibit the spread of fire. It is crucial to invest in fire-resistant decking, such as fire-resistant composite decking, to minimize the risk of fire-related accidents and protect your property and loved ones.

What Should Be The Main Characteristics of Fire-Resisting Materials?

Fire-resisting materials should possess certain key characteristics. Firstly, they should have a high ignition point, meaning they are less likely to catch fire easily. Additionally, fire-resistant materials should have a low flame spread index, indicating that they do not contribute significantly to the spread of fire. Another important characteristic is the ability to resist heat transfer, ensuring that the material does not become a source of fuel for the fire.

Is Composite Decking Fire-Resistant?

Composite decking, made from a combination of wood fibers and recycled plastic, has gained popularity in recent years. Many composite decking materials are engineered to be fire-resistant to some degree. The specific fire resistance of composite decking can vary based on the composition and manufacturing process. It is essential to check the fire resistance rating and certifications provided by the manufacturer before selecting composite decking for your project.

How do You Make a Deck Fire-Resistant?

Enhancing the fire resistance of your deck involves several strategies and techniques. Here are some effective measures to consider:

  • Use Fire-Resistant Decking Materials: Opt for materials specifically designed and tested for fire resistance. Look for products that meet industry standards and have undergone rigorous fire testing.
  • Incorporate Non-Combustible Materials: Utilize non-combustible materials for the substructure, such as steel or aluminum, to reduce the risk of fire spreading from below.
  • Install Fire-Resistant Barriers: Consider adding fire-resistant barriers, such as fire-resistant coatings or membranes, to protect the structural elements of your deck.
  • Maintain Adequate Clearance: Ensure proper clearance between the deck and any flammable objects, such as vegetation or combustible materials, to minimize the risk of fire transfer.
  • Implement Fire-Safe Design: Incorporate fire-safe design principles, such as using fire-resistant railings, non-combustible stair treads, and fire-resistant landscaping around the deck area.

What are the criteria for fire resistance?

Several criteria and standards exist to evaluate the fire resistance of decking materials. These include:

  • Ignition Resistance: The ability of the material to resist ignition when exposed to a heat source.
  • Flame Spread: The rate at which flames spread across the material’s surface.
  • Heat Release Rate: The amount of heat released by the material during combustion.
  • Smoke Production: The quantity and toxicity of smoke emitted by the material when exposed to fire.
  • Structural Integrity: The ability of the material to maintain its structural integrity under fire conditions.

It is essential to consult local building codes and regulations to ensure compliance with the specific criteria for fire resistance in your area. When selecting fire-resistant decking materials, it’s important to choose a reputable manufacturer that offers reliable and tested products. Oakio is a well-known manufacturer in the industry, offering a range of fire-resistant composite decking options. Their decking materials undergo rigorous testing to meet fire resistance standards and provide peace of mind for homeowners. By choosing Oakio fire-resistant decking, you can enhance the safety and protection of your outdoor space.


Investing in fire-resistant decking is a proactive step towards enhancing the safety and protection of your property. By understanding the importance of fire-resistant decking, the main characteristics of fire-resisting materials, how to make a deck fire-resistant, and the criteria for evaluating fire resistance, you can create a secure outdoor space that minimizes the risk of fire accidents. It is crucial to choose fire-resistant decking materials, such as composite decking, that meet the necessary criteria for fire resistance.
