Choose density by assembly
Typical configurable options. Confirm the final specification in the order documentation.
Higher density and thickness can increase low-frequency absorption potential. Confirm with project-specific testing and overall system design.
Supplied performance
| Density (kg/m³) | Thickness (mm) | Application | Acoustic function |
|---|---|---|---|
| 32 | 50 / 80 / 100 | Ceilings, light partitions | Mid–high frequency absorption |
| 48 | 50 / 80 / 100 | Walls, ceilings, studios | Balanced broadband absorption |
| 60 | 50 / 80 / 100 | Walls, cinemas, classrooms | Enhanced low-frequency control |
| 80 | 50 / 80 / 100 | Critical spaces, cinemas | High absorption across low–mid range |
| 96 | 50 / 80 / 100 | High-performance assemblies | Maximum absorption potential |

Material anatomy
Cross-lapped polyester fibres create interconnected voids that convert sound energy into heat through friction and air movement.

Versatile across demanding acoustic environments






Frequently asked questions
Questions before selecting Polyester Fiber Acoustic Insulation.
Clear the material, mounting and evidence questions before the product is released into a project.
Select density and thickness against the intended cavity, target absorption range and the approved wall or ceiling assembly.
Confirm the current product code, dimensions, finish, mounting method, acoustic test conditions and fire evidence against the exact proposed build-up.
Wall and ceiling applications require the exact build-up, cavity depth, linings, support system and current test evidence to be confirmed before release.
Send the room type, drawings or elevations, substrate, target programme and any required compliance information. The project team can then identify the documents and sample route needed for review.
