Acoustic Panels, Learning Functional Panel (LFP)
Learning Functional Panel (LFP) Type-1 Steel
Learning Functional Panels (LFPs)
LFPs 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 LFP panels and fastner systems are ideally suited for correcting noise and reverb problems where people gather or work, including Pools & Recreational Facilities, Theatres & Music Schools & Private Academies, as well as other applications.
