High rise buildings have very strict requirements for the weight of all non structural wall elements because every extra kilogram of dead load adds significant extra cost to the main structural frame and foundation system. EPS Cement Sandwich Wall Panel is the ideal material for high rise construction because it weighs only 75 kilograms per square meter which is around one sixth the weight of a traditional 240mm thick brick wall. This massive weight reduction for all the internal partition walls in a 30 story high rise building can reduce the total structural dead load by thousands of tons which allows structural engineers to significantly reduce the size of columns beams and foundation piles. The direct result of this optimization is that the total structural cost of the high rise building can be reduced by more than 10 percent without any compromise to structural safety. The fast installation speed of EPS Cement Sandwich Wall Panel also creates huge advantages for high rise projects where every day saved on the construction schedule translates to very large financial savings. Installation teams can work on multiple floors at the same time to erect EPS Cement Sandwich Wall Panel units without waiting for long curing periods that are required for traditional cast in place walls. Many of the latest high rise residential and office towers built in recent years have selected EPS Cement Sandwich Wall Panel as their standard internal partition material to achieve both cost and schedule targets.
