Benefits of Plastic Lumber
The biggest advantage of plastic lumber is that it is rot-resistant. Today's plastic lumber materials require little to no maintenance and are extremely resistant to rotting, even in wet environments. The material also resists splintering, cracking, and peeling. Ants and other insects cannot penetrate plastic lumber; neither can bacteria nor barnacles.
Plastic lumber is also resistant to fire, and usually extinguishes itself quickly. In addition, graffiti is easy to remove from the surface of plastic lumber materials.
There are several environmental advantages to using recycled plastic lumber for park site amenities, as well. Unlike rot-resistant treated woods, plastic lumber contains no toxins or heavy metals. Plastic lumber also provides a use for plastics that would ordinarily go into landfills, where they take thousands of years to decompose.
Finally, and most importantly, there are the cost considerations. The initial cost of plastic wood is typically higher than that of traditional lumber. Because plastic lumber lasts longer and requires less maintenance, it ultimately costs significantly less than traditional wood options. Moreover, the price of plastic lumber is likely to continually decrease, as it is a relatively new material.
