Expansion, Contraction, and Failure: How PVC Foam Board Holds Steady Where Other Materials Break Down
Repeated temperature swings are among the most destructive forces acting on industrial building materials—causing expansion gaps, delamination, and structural compromise over time. PVC foam board's low thermal conductivity variance and exceptional dimensional stability make it uniquely suited to environments where temperature cycling is constant. This article examines the mechanics of thermal drift and why materials selection is the most consequential decision facilities managers can make.
