When it comes to flooring options for subfloors, renovations, and construction projects, the Yellow Tongue chipboard available at Bunnings is a widely chosen solution across Australia. Known for its strength, stability, and ease of installation, Yellow Tongue flooring is often used as a structural flooring material in residential and commercial building projects. Whether you are a professional builder or a DIY enthusiast, understanding the features, benefits, and proper handling of Yellow Tongue chipboard can make a significant difference in your construction outcomes.
What Is Yellow Tongue Chipboard?
Yellow Tongue chipboard is a type of ptopicboard flooring panel that features a yellow tongue insert on its edge for easy identification and joining. The ‘tongue and groove’ design allows for a snug fit between panels, providing added stability and helping to prevent movement or squeaking when installed as a subfloor. Manufactured from wood ptopics bonded together under heat and pressure with resin adhesives, Yellow Tongue chipboard is engineered to provide a robust and consistent surface.
Dimensions and Specifications
One of the standard sizes of Yellow Tongue chipboard found at Bunnings is 3600mm x 900mm with a thickness of 19mm. This particular thickness is ideal for residential floor systems where the joist spacing is typically around 450mm. The board is H2 treated, which offers resistance to termites in areas south of the Tropic of Capricorn.
Benefits of Using Yellow Tongue Flooring
There are several key advantages to using Yellow Tongue chipboard from Bunnings for your building or renovation needs. These include:
- Durability: The board is engineered to support heavy loads and foot traffic, making it suitable for long-term use.
- Ease of Installation: With the tongue and groove edges, panels fit together tightly, simplifying the installation process.
- Cost-Effective: Compared to other subfloor options like plywood, Yellow Tongue chipboard is often more affordable without compromising on quality.
- Consistency: The manufactured nature of the product ensures uniform thickness and composition, reducing variations during installation.
Applications in Construction and Renovation
Yellow Tongue chipboard is commonly used in:
- Subfloors beneath carpet, tiles, or hardwood flooring
- Upper-story flooring in two-level homes
- Base layers for sheds or modular buildings
- Temporary flooring during construction projects
Because of its strength and ease of handling, it’s also a preferred material in prefabricated housing systems and can be used in many standard construction scenarios.
Moisture Resistance and Usage Warnings
Although Yellow Tongue chipboard has some degree of moisture resistance, it is not waterproof. Prolonged exposure to water can cause swelling and damage. It is therefore important to protect the boards from weather during and after installation. Bunnings typically recommends storing Yellow Tongue in a dry, covered area, and applying protective coatings if there’s any risk of moisture exposure before final floor coverings are laid.
Installation Tips for Yellow Tongue Chipboard
Proper installation is key to maximizing the performance and lifespan of your Yellow Tongue flooring. Here are some general guidelines:
- Joist Spacing: Ensure joist spacing matches the recommended support structure for 19mm thick boards, typically 450mm centers.
- Adhesive Use: Apply construction adhesive along joists and within the tongue and groove joints to prevent creaking.
- Screw or Nail: Secure panels with appropriate screws or nails, ensuring the fasteners penetrate into the supporting joists.
- Expansion Gaps: Leave a small expansion gap around the perimeter of the room to accommodate any swelling due to humidity or temperature changes.
Cutting and Handling
Cutting Yellow Tongue panels should be done using a circular saw or handsaw with a fine-tooth blade for smooth edges. Always use protective gear such as masks and goggles, as cutting ptopicboard releases fine dust ptopics. If multiple panels are needed, plan your layout in advance to reduce waste and ensure structural integrity.
Comparison with Other Tongue Colors
At Bunnings, chipboard flooring is often color-coded by thickness and intended use:
- Yellow Tongue: 19mm thick, suitable for 450mm joist spacing
- Red Tongue: 22mm thick, suitable for 600mm joist spacing
- Blue Tongue: Typically used for high moisture areas
The color-coded system helps builders quickly identify the right product for their structural needs.
Environmental Considerations
Yellow Tongue chipboard is generally produced from plantation-grown timber and recycled wood material, making it a more sustainable option than some alternatives. When selecting your flooring panels, look for boards that are certified for low formaldehyde emissions and environmental compliance. Many Bunnings stores carry products that meet environmental building standards, making them suitable for eco-conscious builders.

Pricing may vary based on region and stock, but it remains one of the more budget-friendly structural flooring choices.
