The global stock of aging urban residential buildings is huge, and most of these old apartments face common problems like poor insulation, thin partition walls and insufficient indoor space. The EPS cement sandwich wall panel has emerged as a perfect solution for fast, low-disruption old building renovation projects. Unlike traditional renovation methods that require long periods of messy demolition and heavy construction, using an EPS cement sandwich wall panel for interior wall replacement produces almost no construction dust and noise.

A standard 100mm thick EPS cement sandwich wall panel is 120mm thinner than the original old brick partition wall, which can add 3% to 5% more usable indoor space for each apartment, a very attractive benefit for residents living in crowded cities. The excellent thermal insulation performance of the EPS cement sandwich wall panel can also upgrade the old building’s energy efficiency by 40%, helping residents cut their monthly heating and cooling bills significantly.

Many urban renewal projects in Seoul, Shanghai and Berlin have chosen the EPS cement sandwich wall panel for large-scale old building renovation. The whole renovation process for one 80-square-meter apartment can be finished in just 7 days, with minimal disruption to residents’ daily lives, far faster than the 30+ days required for traditional renovation methods.
