PET Acoustic Panel 12mm 2840x1220mm White Extra Long Seamless Wall Design
Cover height and width with fewer seams using this 12mm white PET acoustic panel in an extra-long 2840*1220mm format. Made from 100% recycled polyester fiber thermally bonded without chemical adhesives, it is 100% formaldehyde-free and ready for immediate use. The 12mm thickness provides an NRC of 0.85, effectively absorbing 85% of incident sound to reduce reverberation and improve speech clarity. The panel’s extended length means it can cover floor-to-ceiling in many standard rooms with zero horizontal joints, creating a stunning seamless acoustic wall. Weighing approximately 2.7 kg/m², it remains manageable for two-person installation. With OEKO-TEX certification and Class B1 fire rating, this panel meets rigorous health and safety standards for commercial and residential projects.
Designers and architects often struggle with acoustic treatments that break up visual flow with visible panel joints. This extra-long panel solves the aesthetic challenge by offering full-height installation without horizontal interruptions. It creates a clean, monolithic look on feature walls, behind reception desks, or along long corridors. The acoustic benefit is equally seamless: no untreated joint gaps means more uniform sound absorption along the entire wall length.

Hotel reception backdrops, corporate lobby feature walls, long corridor wall linings, and open-plan office wings where a seamless, high-end finish is desired.
The panel absorbs sound along its entire uninterrupted surface. By eliminating horizontal joints, it prevents the periodic acoustic reflections that occur at untreated seams, providing a more consistent reverberation decay across the wall.
Opt for the 2840mm length if your ceiling height is between 2.4m and 2.8m and you desire a true seamless look. Check your site access to ensure long panels can be maneuvered into place.
