LFPs are suitable for new or existing educational facilities. Since the specified level of noise reduction often requires that less than 25 to 30% of the reflective surface be covered, the panels can be installed around sprinkler heads, lighting fixtures, heating and ventilation ducts. They are particularly effective in school gyms, hallways, cafeterias and auditoriums while also providing noticeable acoustic improvement in a wide arrange of settings such as assembly halls, religious facilities, and multi-purpose rooms. Installing EFPs can meet or exceed requirements for safe noise thresholds thereby creating a healthier and more effective environment for study.
ELPs provide an extremely rugged noise control system for schools, colleges, universities and learning academies. From classrooms and hallways to music practice and staff offices, specially strengthened ELP panels and fastner systems are ideally suited for correcting noise and reverb problems where people gather or work, including Pools & Recreational Facilities, Theatres & Auditoriums, Music Schools & Private Academies, as well as other applications.
