When you relax on a park bench, you're probably not thinking about the sophisticated wood treatment processes that protect it from nature's elements. The majority of public park benches are indeed specially treated to resist insect damage, moisture, and fungal decay. Most municipalities use pressure-treated lumber that undergoes a complex preservation process where wood is placed in a pressurized tank, forcing preservative chemicals deep into the wood fibers. These chemicals—typically ACQ (Alkaline Copper Quaternary) or copper azole—create an environment that's toxic to insects like termites and carpenter ants while being safe for human contact once sealed. The treatment also protects against wood-destroying fungi and moisture penetration that can lead to rot. Some higher-end benches may use naturally resistant woods like cedar or redwood, which contain natural oils that deter insects. Regular maintenance including sealing and staining helps maintain this protective barrier over years of exposure to weather and use. So next time you sit on that park bench, appreciate the science that keeps it sturdy and insect-free season after season.
Is the wood for these park benches treated to resist insect damage?
