Acoustic Sealing

Sealing gaps, joints and penetrations to stop noise travelling between rooms, often alongside fire seals.

Sound finds its way through the smallest gaps. Acoustic sealing closes the joints, perimeters and penetrations in walls, floors and ceilings that let noise travel between rooms and units, improving comfort and privacy.

Where we work

Acoustic sealing is important in apartments, hotels, offices, schools and healthcare buildings, anywhere that privacy and comfort matter. We commonly seal wall and floor perimeters, junctions between different materials, service penetrations, and the interfaces around doors, windows and access panels.

Fire and acoustic performance together

Many of the gaps that need acoustic sealing are in fire-resisting construction too. We select tested products that deliver acoustic performance without compromising fire resistance or movement tolerance, so a single detail can meet both requirements.

Coordinated with your other works

  • Sealing coordinated with partition upgrades, fire stopping, cavity barriers and fire doors.
  • Details that are practical to build on site and consistent with the design.
  • Clear records showing how the acoustic line has been maintained.
