01 / The panel
Engineered for predictable absorption, batch after batch
MMTPL manufactures Echsorbix® panels at the Palwal plant, running since 2023, on needle-punching machinery that improves fibre interlocking and keeps density distribution uniform. That is what makes performance repeatable across batches on a large BOQ.
Absorption is validated by NRC testing to ASTM C423, which in a room means better speech clarity and less echo build-up, without the treatment fighting the design intent.
Standard thicknesses of 9, 12, 18 and 24 mm, custom from 4 to 24 mm, a 1200 to 3600 GSM range and panels up to 2440 x 4270 mm, 8 x 14 ft, give a specifier room to hit RT60 targets zone by zone rather than treating every surface the same.
- NRC tested, ASTM C423. Reliable absorption figures for professional acoustic treatment.
- Thickness options. Standard 9 to 24 mm, custom 4 to 24 mm for zone-wise targeting.
- 1200 to 3600 GSM. Higher GSM gives better durability and absorption potential.
- Large format. Panels up to 2440 x 4270 mm, 8 x 14 ft, mean fewer joints on long runs.
- 40+ colours. Wide palette with custom colour development for large projects.
- CNC cutting and printing. Precision profiles, patterns and branding-ready surfaces.
- Durable and lightweight. Easy handling, faster installation, low maintenance.
- Low VOC and recyclable. Minimum 60% recycled content, 100% recyclable.
