Acousti AcoustiPack ML 2-layer 4mm OEM Material

This product is one sheet of AcoustiPack ML (multi-layer) 2-layer 4mm soundproofing material, dimensions 431 x 457mm (17" x 18"). AcoustiPack Ultimate contains two of these sheets plus a sheet of APML-3L7 (3-layer, 7mm).


  1. Bulk sheets of 2-layer acoustic material, sold singly
  2. Designed for PC system builders or industrial applications
  3. Material sheet is dual-layer acoustic composite, 4mm thick
  4. Dimensions are 431 x 457mm (17" x 18")
  5. Highly acoustically effective and cost effective

The range of AcoustiPack™ sound-proofing kits has been designed with customer's pockets and greater flexibility in mind! As a result, Acousti have introduced AcoustiPack™ 2-layer Sheet (4mm), which is a single large sheet of their latest generation acoustic material (as found in AcoustiPack Ultimate). This sheet is ideal if additional materials are required for a particular project, and the space allows for a 4mm sheet to be added. This product makes the range of acoustic material kits more flexible, and can help to save money and waste when an entire kit, such as ULTIMATE or LITE is not necessary.
