That’s a great question, and it’s one that often comes up when people notice the natural look of urban benches. The short answer is: it depends on the specific bench and its location, but most modern urban benches are not just raw timber—they are almost always treated with some form of fire retardant, especially if they are installed in public spaces.
Here’s the breakdown. Raw timber, while beautiful and sustainable, poses a significant fire hazard, particularly in crowded urban areas, parks near dry brush, or along transit routes where discarded cigarettes or barbecues might ignite it. To comply with local fire codes and insurance requirements, municipalities and manufacturers typically apply a fire retardant treatment to the wood. These treatments are often pressure-impregnated or sprayed onto the timber, and they are designed to inhibit combustion, slow the spread of flames, and reduce smoke output.
However, the type of treatment can vary. Some benches use a chemical fire retardant that is clear and doesn’t alter the wood’s natural grain or color, making them look very much like raw timber. Others might be made from composite wood or timber that has been kiln-dried and treated with a factory-applied fire-resistant coating. In rare cases, smaller or less-regulated installations might use untreated wood, but that’s becoming less common due to liability concerns.
So, when you see that beautiful, natural-looking bench at the park, it’s very likely treated with a fire retardant—it just looks like raw timber. Always check the manufacturer’s specifications or the local park maintenance records if you need 100% certainty, but for safety’s sake, treat all urban benches as if they are treated until you know otherwise.
