Choose density by assembly

Match density and thickness to your target performance

Density (kg/m鲁)

Thickness (mm)

Higher density and thickness can increase low-frequency absorption potential. Confirm with project-specific testing and overall system design.

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.

01How should Polyester Fiber Acoustic Insulation be selected for a project?

Select density and thickness against the intended cavity, target absorption range and the approved wall or ceiling assembly.

02Which technical information should be confirmed before specification?

Confirm the current product code, dimensions, finish, mounting method, acoustic test conditions and fire evidence against the exact proposed build-up.

03Can this material be used on both walls and ceilings?

Wall and ceiling applications require the exact build-up, cavity depth, linings, support system and current test evidence to be confirmed before release.

04How do I begin a sample or technical enquiry?

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.
