Fire Retardant Plywood (5 Products)

Fire retardant plywood is a specialist type of plywood that has been chemically treated with a fire retardant solution using high-pressure impregnation, followed by kiln drying to achieve a specific moisture content. This process ensures that when FRT plywood comes into contact with fire the material is unable to oxidise and will simply char upon exposure as opposed to burning. Consequently, it serves as an effective barrier against the surface spread of flames.

Fire Retardant Plywood

What Is Fire Retardant Birch Plywood? 


Fire retardant birch plywood is a plywood type that has been chemically treated and soaked in a special fire retardant liquid solution. This method of treatment is more reliable and long-lasting than surface coatings.

Boasting fire retardant properties, FR plywood is fire proofed making it flame retardant to either Euro class B or C.


Suitable for structural use, Fire Retardant Birch Plywood carries a full CE Mark for use in humid structural applications (EN 636-2), another certification that further testifies the product's durability. 

Fire Retardant Plywood Applications

Fire retardant plywood is a universal material which can be employed in both commercial and residential applications. 

FR plywood can be utilised in specialist regulated environments and projects requiring safety and certification. Fire-retardant wood panels are commonly used by automobile and boat builders, as well as in the London Underground.

Aside from that, FR plywood is regularly used for a variety of construction applications that need timber with reliable fire performance, such as theatres, TV and film sets, and restaurant kitchens, where the hazard of fire is more likely. 


Fire-rated plywood offers superior fire performance in interior elements such as:

  • Framing

  • Stairwells

  • Trusses

  • Roof panels

  • Sidewall sheathing

Fire Rated Plywood Key Features

  • Flame retardant treatment improves fire resistance without compromising the plywood's technical performance 

  • Inhibits fire growth by slowing down lateral flame spread

  • FR plywood panel products that meet the appropriate BS EN standards are able to reduce flammability and limit smoke production

  • Slows rate of fire growth

Frequently Asked Fire Retardant Plywood Questions

Frequently Asked Questions About Fire Retardant Plywood

How Does The FR Treatment Work? 

The fire retardant treatment used in the manufacturing process makes the wood more resistant to fire and flame spread, which can help slow or prevent a fire from spreading.


The chemicals used in FR plywood creation help to reduce the panel's reaction to fire, limiting total heat release and smoke production emissions.

What Should Be Taken Into Consideration When Buying Fire Retardant Plywood? 

Before beginning any project, checking the product specs and certifications is key, especially when working with fire-retardant sheet materials.

When fire safety really has to count, fire-rated plywood can make a huge difference to the survival chances of those inside when the fire breaks out. It won't completely fireproof your house but it will gain vital minutes for those inside to escape.


When purchasing fire-resistant plywood, ensure that you check it for:

  • Product name and species

  • The flameproof abilities of the material

  • The method by which the material was dried

  • Flame spread specifications

  • Smoke developed number

Is FR Plywood Still Fire Retardant After Cutting? 

Yes, the treatment method used to manufacture FR plywood is more durable than surface coatings - the fire retardant properties will remain after cutting or machining.

What Is The Single Burning Item Test? 

The SBI test is used to classify building products in accordance with BS EN 13501 1.
The test determines the material's behaviour in a fire, including ignitability, heat release, and its production of burning droplets. If the product meets European classifications after testing, it is given a European class.
