Eckel Correctional Panel (ECP) Type-1 CE Steel

ECPs provide an extremely rugged noise control system for jails, correctional and high security facilities and feature specially strengthened panels and fastner systems. ECPs are ideally suited for correcting noise and reverb problems where people gather or work, including Pools & Recreational Facilities, Theatres & Auditoriums, Music Schools & Academic Environments, Power Plants & WWTPs as well as other Industrial & Transportation applications. For high humidity applications such as indoor pools or where panels may be exposed to oils or vapours, or for installation in dust-free clean rooms, the 2″ (51mm) thick, fine fibered, fibrous glass acoustical insulation may be enclosed in 1.5-2 mil flameguard polywrap. All ECP Types are available in 4′ (1.2m), 5′ (1.5m), 6′ (1.8m), 8′ (2.4m), and 10′ (3.0m) sizes, permitting application in large or small spaces, as well as, restricted areas. Standard panel size is 10′ (3.0m).
