1. 18mm Ply for Framing: This is likely for building the frame of the room or creating partitions.

2. 1000 GSM, 50mm Insulation Wool: This refers to insulation material with a density of 1000 grams per square meter (GSM) and a thickness of 50mm. It's used to reduce sound transmission and improve thermal insulation.

3. Wood Wool Board or Perforated MDF Board: These materials are used for acoustic panels to improve sound absorption within the room. Wood wool boards have natural sound-absorbing properties, while perforated MDF boards allow sound waves to pass through the perforations and be absorbed by the material behind them.

4. Gripper Infill with PU Foam: This involves using a gripper (a type of metal framing system) filled with polyurethane (PU) foam. The PU foam provides additional soundproofing by sealing gaps and absorbing sound energy.

5. Finish with Acoustic Fabric: Finally, the walls and panels are covered with acoustic fabric. This fabric is designed to allow sound waves to pass through while minimizing reflection, thereby enhancing the room's acoustic properties.

These materials work together to create a room with improved sound quality and reduced external noise interference.
