Old building renovation projects often face tight budgets and limited construction time windows, and the EPS Cement Sandwich Wall Panel is a perfect solution to solve both of these pain points. Since the EPS Cement Sandwich Wall Panel is extremely lightweight, you do not need to reinforce the original old building foundation before installing new partition walls, saving a huge amount of structural modification cost. The fast installation speed of the EPS Cement Sandwich Wall Panel means the whole renovation construction period can be cut by more than half, reducing the disturbance to surrounding residents or existing business operations. You can directly install the EPS Cement Sandwich Wall Panel on top of the original old uneven wall surface, without the need to knock down and remove the original old wall completely. Many old hotel renovation projects that adopted the EPS Cement Sandwich Wall Panel finished their full upgrade and reopened for business 3 weeks ahead of the original planned schedule.
