The Global Copper Azole Wood Preservatives Market was valued at USD 412.8 million in 2023 and is projected to reach USD 572.3 million by 2030, growing at a Compound Annual Growth Rate (CAGR) of 4.8% during the forecast period (2024-2030). This growth is driven by increasing infrastructure development, rising demand for pressure-treated lumber in construction, and stringent environmental regulations phasing out chromated copper arsenate (CCA) preservatives.
As environmental concerns reshape wood treatment standards globally, copper azole has emerged as one of the leading alternative preservation systems. Copper azole formulations combine copper’s fungicidal properties with organic co-biocides for superior protection against decay fungi and insects. These factors make the technology particularly relevant for decking, fencing, and structural applications.
