Is It Safe to Put a Fire Table on Composite Decking?

Can you really put a fire table on composite decking without turning your backyard into a blazing disaster? Short answer: Yes, but only if you take the right steps! Read on to learn how to safely enjoy cosy evenings by your fire table, without damaging your deck or your peace of mind.

Safety Considerations for Composite Decking

Combustibility and Melting Point:

Understanding the Composition of Composite Decking

Composite decking is a modern alternative to traditional timber, blending wood fibres with plastic to create a low-maintenance, long-lasting outdoor surface. It’s a fantastic option for homeowners who want beauty and durability without the upkeep of natural wood. However, it’s important to remember that, while composite decking is fire-resistant to some extent, it is not fireproof.

Different brands and types of composite materials offer varying levels of heat resistance, so knowing the composition of your decking is crucial. Some decks will withstand heat better than others, but excessive heat—especially from a fire table—can still cause problems over time.

Potential for Melting or Warping from Heat

Composite decking can warp or melt when exposed to extreme heat. Fire tables generate a lot of warmth, and placing one directly on your deck without any protection is a recipe for disaster. While the decking may not catch fire immediately, it can still become damaged by prolonged exposure to high temperatures.

The good news? You can protect your deck with the right precautions. So, don’t skip this step—you’ll want to keep your decking looking good for years to come.

Heat Transfer and Damage:

Direct Heat from the Fire Table

When you place a fire table on your composite deck, direct heat is transferred to the surface below. Without a proper heat shield, the deck could suffer. The intense heat from the table could cause the decking to soften, warp, or even discolour. A fire table should be used with caution, especially if you’ve got composite decking.

Potential for Discolouration or Damage

Even if your deck survives the heat, there’s still the risk of unsightly discolouration. A fire table can leave marks or faded spots on your decking, particularly if it’s exposed to high heat for long periods. While it may not be an immediate problem, over time the damage can accumulate, leaving your outdoor space looking worn and tired.

Protective Measures

Heat-Resistant Mats or Barriers:

Materials Like Concrete Pavers, Stone Slabs, or Specialized Mats

The best way to protect your composite decking is by using heat-resistant mats or barriers. Concrete pavers, stone slabs, and special heat-resistant mats are great options for absorbing heat and preventing it from transferring to your deck. These barriers act as a shield, absorbing the heat while keeping your deck safe from direct exposure.

Proper Sizing and Placement

Choosing the right size for your protective barrier is key. The mat or paver should be large enough to cover the area under your fire table, extending beyond the base by a few inches. This ensures that any heat or sparks are contained within the protected zone. Placement is just as important—make sure the barrier is centred beneath the fire table and doesn’t shift during use.

Clearance and Ventilation:

Maintaining a Safe Distance from Combustible Materials

One of the most crucial safety steps is ensuring there’s enough space between your fire table and any nearby structures or flammable materials. Your fire table should be placed at least 10 to 15 feet away from walls, fences, and overhanging trees. This distance prevents the heat from spreading to vulnerable areas, reducing the risk of fire hazards.

Ensuring Adequate Ventilation

Good airflow is essential when using a fire table on your deck. Ensuring proper ventilation allows heat to dissipate and prevents excessive buildup. A fire table with raised legs can help encourage airflow, preventing heat from being trapped under the table and reaching the deck surface. It’s important to keep the area around your fire table clear to avoid obstructing airflow and limiting ventilation.

Fire Table Design and Features

Low-Profile Fire Tables:

Reduced Heat Transfer to the Surface

If you’re worried about heat damage, consider investing in a low-profile fire table. These tables sit closer to the ground, which means they transfer less heat to the surface below. By reducing the heat concentration, you’re lowering the risk of warping or discolouration to your composite decking. A low-profile fire table is a good choice for those who want the beauty of a fire feature without the potential damage to their deck.

Built-in Safety Features:

Flame Height Adjustment and Safety Shut-Off

Modern fire tables often come with built-in safety features that make them safer to use on composite decking. Many models allow you to adjust the flame height, which can help control the amount of heat emitted. Some even come with an automatic shut-off mechanism that ensures the fire is extinguished safely after use, preventing any unwanted fire risks or accidents.

Maintenance and Monitoring

Regular Inspections:

Checking for Damage or Wear

Regular maintenance is essential for keeping your fire table and composite decking in top shape. After each use, inspect both the fire table and the deck for signs of wear or damage. Look for heat-related issues, such as softening or cracking in the decking. By staying on top of regular inspections, you’ll spot potential problems before they escalate into costly repairs.

Fire Safety Precautions:

Having a Fire Extinguisher or Water Source Nearby

Safety should always come first. Always keep a fire extinguisher or water source close by when using a fire table. Accidents can happen, and being prepared can prevent small issues from becoming large, dangerous fires. Make sure everyone in your household is aware of fire safety procedures, and if you’re unsure how to use a fire extinguisher, it’s worth doing a quick refresher course.

Conclusion

Putting a fire table on your composite decking is possible—if you take the right precautions. By understanding the materials you’re working with, using proper heat-resistant barriers, and ensuring your fire table is designed with safety in mind, you can enjoy the warmth and beauty of a fire feature without damaging your deck. Regular maintenance, safety features, and fire safety measures will keep your outdoor space functional, safe, and beautiful for years to come.

With a little planning and care, you can create the ultimate outdoor oasis. Just remember to follow these guidelines, and you’ll be toasting marshmallows by the fire without a worry in the world.
