As the number of people owning villas increases, the use of preservative-treated wood is also on the rise. Preservative-treated wood is first solid wood, and due to its natural wood nature, it is prone to cracking, rotting, and warping. However, preservative-treated wood undergoes a meticulous process where selected solid wood is placed in a sealed pressure preservative tank. The wood is then infused with preservatives using vacuum pressure. This entire process is quite sophisticated, resulting in preservative-treated wood that typically has a lifespan of thirty years.
