Eckel Functional Panel (EFP) Type-4 – Aluminum

Pre-engineered EFP panels come in a range of sizes and styles. They can be readily positioned within the host room to achieve optimal noise reduction performance. Available in aluminum or steel, panels can be customized and finished to fit and complement any architectural layout or interior design. Easy to install during new construction or as a retrofit item, EFPs are an economical and effective means to control noise and create ideal acoustic conditions.

EFPs turn a noisy room into quieter and more accommodating space better suited to its designed purpose.
