REPORT STATEMENTS: 1.4.1 ENVIRONMENTAL REASONS TO USE PLASTIC LUMBER |
|
"Plastic Lumber is becoming an appealing material to use due to environmental concerns. …. Plastic does not decompose from contact with the soil. This was the problem with
land-filling plastic. In this case, a previously detrimental property has become a beneficial property. Environmental regulations are also making plastic lumber a material of choice. Many parts of the country are enacting legislation making it illegal to place pressure treated lumber into water.....Plastic Lumber will not degrade and will not release any chemicals into the water.
RSP Lumber is an environmentally friendly product." |
|
REPORT STATEMENTS: 1.4.2 ECONOMIC REASONS TO USE PLASTIC LUMBER |
|
"There are economic reasons to use plastic lumber. Plastic lumber does cost more than traditional wood lumber. …This means that a customer will have a greater initial investment to make. However, when the cost of plastic lumber is calculated over its lifetime, it becomes more cost effective than wood. Plastic lumber requires less maintenance than
wood. Once it is setup, it should not need to be painted at all. It will not need to be waterproofed on a yearly basis because it is waterproof by its physical nature. Plastic planks will not splinter or crack.
There will generally be no maintenance after construction is completed." |
