Fire rated plywood is an excellent choice for a variety of building projects. Enhanced by a cutting-edge treatment, it offers exceptional fire resistance that remains effective even after sanding or machining. Designed to endure high heat and prevent flame spread, this plywood provides crucial safety in construction. Additionally, it is constructed for long-lasting durability, making it ideal for projects that require resilience and performance under demanding conditions.

What plywood is fire rated?
Fire rated plywood is specially treated with chemicals to create a barrier against flame spread. While it chars when exposed to fire, it does not oxidize, significantly slowing down fire progression in buildings. This charring provides an added layer of protection, further enhancing the material's resistance to burning.
Fire-Rated Plywood has 3 classes: Class A, Class B, Class C. Among them, Class A is the highest rating for fire-rated plywood, indicating a flame spread index of 25 or lower. To substitute fire-retardant wood for noncombustible materials, it must have a Class A rating. This category also includes inorganic materials such as tile and brick, which are known for their fire-resistant properties.

How is fire rated plywood made?
Fire-rated plywood is made through a specialized treatment process that involves infusing the wood with fire-retardant chemicals. Here’s an overview of the steps typically involved in the production of fire-rated plywood:
- Selecting the Wood: The process begins with selecting suitable types of plywood, which generally involves high-quality layers of wood veneer. Common types include fir, pine, or other hardwoods.
- Preparation: The plywood panels are cut to size and prepared for treatment. This may involve sanding or sorting to ensure uniformity.
- Chemical Treatment: The plywood is treated with fire-retardant chemicals. These chemicals can be applied through processes such as pressure treatment, where the wood is placed in a vacuum chamber and the chemicals are forced into the wood fibers. Alternatively, the chemicals may be sprayed or brushed onto the surface.
- Drying and Curing: After the application of the fire-retardant chemicals, the plywood is usually dried in a controlled environment to ensure that the chemicals properly bond to the wood.
- Testing for Compliance: The treated plywood is then subjected to rigorous testing to ensure it meets specific fire-rated standards. This testing usually evaluates how the material performs under high heat and flame exposure, measuring characteristics such as flame spread and smoke development.
- Finishing: After passing fire rating tests, the plywood may receive additional treatments to enhance water resistance or durability, particularly for exterior applications. This ensures that the fire-retardant chemicals remain effective even in wet conditions.
- Labeling and Certification: Finally, the fire-rated plywood is labeled and certified according to relevant safety standards, indicating its fire resistance properties, which is crucial for compliance in building construction.
Fire-rated plywood is thus an essential material in construction, particularly for areas that require additional fire protection, and contributes significantly to safety in buildings.

Benefits of Fire Rated Plywood
Fire-rated plywood offers numerous advantages, making it a popular choice in construction. Here are some key benefits:
- Deep Chemical Treatment: Unlike surface coatings, fire-rated plywood is pressure impregnated with fire-retardant chemicals, providing long-lasting protection against fire, termites, and other hazards.
- Certification and Safety: Each panel is certified and stamped, ensuring it has been professionally treated and inspected, reducing the risk of exposure to harmful chemicals.
- Protective Char Formation: When exposed to fire, a protective char forms, insulating the wood and slowing down burning, which helps safeguard structures under construction.
- Potential Insurance Savings: Using fire-rated plywood may lower insurance premiums, as it enhances fire safety, providing documentation that your home is well-protected.
- Easy Installation: It can be installed with standard woodworking tools, eliminating the need for specialized equipment and reducing overall costs.

Is 18mm plywood fire rated?
Yes, 18mm plywood can be fire rated, provided it has undergone the appropriate fire-retardant treatment and meets certain fire safety standards.
18mm Fire Retardant Plywood has been treated in a way that enhances its fire resistance. Specifically, the treatment process involves treating each layer of the plywood separately, which contributes to a clean appearance and increased sturdiness. When exposed to fire, this type of plywood will char but will not burn rapidly, effectively slowing the progress of flames.
Additionally, the categorization of this plywood as Euro Class B suggests it meets European standards for fire safety, indicating that it has a good level of fire resistance.
If you're considering using this type of plywood, ensure that it is certified and stamped with its fire rating, as this will give you confidence in its performance in case of fire. Always consult with suppliers or manufacturers for specific details regarding the fire rating and intended applications.

Is 12mm ply fire rated?
Yes, the 12mm fire-rated plywood is specially treated to enhance its fire resistance. This treatment involves the application of fire retardant chemicals that help inhibit the wood's ability to oxidize, making it more resistant to flames. In the event of a fire, this type of plywood is designed to char rather than sustain burning, which helps slow down the spread of fire and offers a greater level of safety.
It's important to ensure that the specific product complies with relevant fire safety standards and codes applicable to your location or project. Always check for certification and specifications from the manufacturer regarding its fire rating and performance.
