We completely understand your concern! The warm, natural aesthetic of wooden benches is undeniable, but their longevity in an urban setting is a valid consideration. The good news is that with the right choices and care, wooden benches can indeed be a durable and long-lasting addition to public spaces.
The key to longevity lies in the type of wood selected. Not all woods are created equal for outdoor use. Opt for naturally durable and rot-resistant species like teak, cedar, or white oak. These woods contain natural oils and tannins that help them resist moisture, insect damage, and decay. Alternatively, many modern wooden benches are made from thermally modified wood or acetylated wood (like Accoya®), processes that permanently enhance the wood's stability and resistance to biological decay.
Another excellent option is to choose pressure-treated lumber. This wood is infused with preservatives that protect it from rot and insects, making it a cost-effective and robust choice for high-use public areas.
Beyond material selection, protective finishes are crucial. A high-quality sealant, oil, or stain forms a protective barrier against UV rays and water penetration. This finish needs to be reapplied periodically, as recommended by the manufacturer, to maintain its protective qualities. Regular maintenance, such as cleaning and inspecting for minor damage, will significantly extend the bench's life.
So, while your concern is warranted, modern wood technology and proper maintenance practices make wooden benches a viable and beautiful long-term solution. By investing in the right species and a simple upkeep routine, you can enjoy the classic look of wood without sacrificing durability.
