What property of PVC siding makes it susceptible to environmental damage?

High thermal conductivity
Low flexibility
Material brittleness
Susceptibility to extreme temperatures

The correct answer is: Susceptibility to extreme temperatures

PVC siding is made from polyvinyl chloride, which can be adversely affected by extreme temperatures. The material becomes less flexible and more brittle when exposed to very low temperatures, making it prone to cracking and breaking. Conversely, high temperatures can also lead to warping, deformation, and potential degradation of the material due to the heat impacting the structural integrity. This susceptibility to both ends of the temperature spectrum significantly reduces the lifespan and performance of PVC siding, as it may not effectively withstand the environmental conditions to which it is subjected over time. Thus, recognizing the impact of extreme temperatures is crucial for understanding how PVC siding can experience environmental damage.
