Many new users of EPS Cement Sandwich Wall Panel often ask about its actual long term service life, and whether it can maintain its original performance after decades of use. There are now thousands of buildings around the world that have used EPS Cement Sandwich Wall Panel for more than 20 years, and independent field inspection teams have collected detailed performance data from these old projects. The real world data shows that high quality correctly installed EPS Cement Sandwich Wall Panel can easily deliver more than 30 years of reliable service life, with almost no degradation of original performance.
The 20 year field inspection results show that 92% of the inspected panels from projects built in early 2000s still maintain their original structural strength, and the thermal conductivity performance only changed by less than 3% after 20 years. Almost all the panels still have intact cement skins with no cracking, delamination or core shrinkage issues. The very small number of panels that showed minor performance problems were all from early generation low quality products that used low density EPS core and low quality cement board skins, not standard quality modern EPS Cement Sandwich Wall Panel.
The only regular maintenance required across the whole 20 year period was replacing the weather sealant along panel joints once every 10 years, and repainting the exterior wall surface once every 8 to 10 years. No major wall repair work was needed for any of the inspected buildings. This real world 20 year data proves that the long term life expectancy of EPS Cement Sandwich Wall Panel is equal to, or even better than, the service life of traditional brick and concrete block walls. It is a long term durable building material, not a temporary low quality disposable construction product.
