When choosing wall materials, many people only pay attention to the initial purchase price but ignore the maintenance and replacement cost in the later stage, and EPS Cement Sandwich Panel has an ultra-long service life of more than 70 years, which greatly reduces the total cost of the building in the whole life cycle. The inorganic cement-based composite structure of the panel will not age, decompose, or be corroded easily, and its performance will not degrade significantly even after decades of use. Unlike some organic insulation materials that need to be replaced every 10 to 15 years, this panel can maintain its original fireproof, sound insulation, and thermal insulation performance for more than 70 years without needing large-scale renovation. This means that building owners do not need to invest extra money in wall maintenance and replacement for a long time, and can save a lot of trouble and cost. For long-term investment projects such as commercial real estate, industrial parks, and public facilities, this long service life advantage makes the return on investment cycle far better than using traditional wall materials, bringing more stable long-term economic benefits.
