A large corporate headquarters auditorium needs to meet extremely strict performance requirements: perfect sound insulation to prevent external noise from disrupting events, excellent acoustic properties for clear speech intelligibility, and full compliance with public assembly fire safety codes. The EPS Cement Sandwich Panel delivers on every single one of these requirements, with 150mm thick panels achieving sound insulation levels of over 50 decibels that block all external corridor and office noise from entering the auditorium. The panel’s layered structure also creates excellent natural acoustic diffusion that reduces unwanted echo inside the large event space, reducing the amount of extra acoustic treatment material you need to install. Its 4-hour fire resistance rating fully meets all local public assembly building safety codes, making your 300+ seat auditorium fully compliant for large company events and external guest activities.
