Service life depends on substrate quality, installation environment and maintenance. The ratio of PVC to stone powder in the substrate, and the foaming rate, are the key quality factors.
In normal use:
- PVC wall panels: about 10-15 years (quality products 20+ years);
- WPC wall panels: 15-25 years, outdoor-grade 25+ years;
- Carbon crystal panels: up to 20 years if kept away from high heat and direct sunlight.
