Recycled plastic lumber is worth considering as an alternative to traditional lumber for most building projects, with the exception of interior residential projects.Which of the following, if true, most helps to explain the exception noted above? Residential homes built entirely with recycled plastic lumber are virtually immune to damage from flooding. Increased rates of thermal expansion and contraction of plastic lumber can cause doorways constructed of this material to warp and either fail to close or fail to seal tightly. Currently 25 percent of the trash that is in landfills is plastic that could be used to produce recycled plastic lumber.
