Wholesale PET Acoustic Panel Manufacturer 1220x2800mm Polyester Fiber Soundproof Panel for Global Projects
-
Seamless Floor-to-Ceiling Coverage: The 2800mm extra-tall height fits standard and elevated commercial ceiling heights in a single panel, minimizing horizontal joints for a flawless wall finish.
-
Superior Sound Absorption (NRC ≥ 0.85): High-density polyester fiber structure absorbs ambient echo, controls reverberation, and enhances speech clarity across large open spaces.
-
Eco-Friendly & Safe Standard: Manufactured from 100% recycled PET, achieving E0 formaldehyde-free safety ratings and B1 / ASTM E84 Class A flame retardancy.
-
Easy Fabrication & Installation: Lightweight yet structurally stable. Cleanly cut, bevel, or CNC-engrave using standard tools; install using spray adhesive or mechanical fasteners.
-
Engineered for Commercial Architecture: Ideal for hotel lobbies, Grade-A office buildings, auditoriums, conference centers, and high-ceiling residential spaces.
Why Choose 1220×2800mm Oversized Acoustic Panels?
-
Zero Horizontal Seams: Standard 2440mm panels leave noticeable gaps on taller walls. The 2800mm length provides full vertical coverage for seamless architectural integration.
-
Reduced Labor & Installation Time: Larger panel surface area means fewer pieces to measure, align, and join, significantly speeding up project completion times.
-
Optimized for Custom V-Grooving: The expanded sheet size offers continuous canvas area for large geometric patterns, custom CNC routing, and modern acoustic baffle fabrication.

FAQ
PET acoustic panels are designed for sound absorption. They absorb sound reflections inside a room to eliminate echo, reduce reverberation, and improve speech clarity. They do not block sound from transferring through walls into adjacent rooms
Our standard 9mm and 12mm panels achieve an NRC rating ranging from 0.85 to 0.95 (depending on installation method and air gap backing), meaning they absorb up to 95% of sound energy hitting their surface.
Yes. Made from 100% polyester fiber (recycled PET plastic bottles), our panels are E0 formaldehyde-free, non-toxic, odorless, and release zero VOC
