Confidential executive meetings, sensitive strategy discussions, and private one-on-one performance reviews require absolute acoustic privacy, something that traditional thin drywall systems simply cannot deliver for corporate headquarters environments. The EPS Cement Sandwich Panel’s unique layered structure combines the sound-absorbing properties of its closed-cell EPS foam core with the sound-blocking density of its reinforced cement surface layers, creating a dual acoustic effect that far outperforms standard drywall. A 120mm thick panel designed for executive office walls can achieve sound insulation levels of over 48 decibels, meaning no sound from inside a closed boardroom will ever be overheard by people walking through adjacent corridors. Even loud discussions in the main open-plan work zones will never disturb executives working in private corner offices. This level of acoustic performance eliminates the need for expensive extra acoustic treatment materials, letting you create fully private executive zones at a far lower total construction cost.
