Acoustichoc® Impact 15 ceiling: 600 x 600 x 22 mm

  • T24 or T35 runners should be arranged in parallel lines every 1,200 mm. Every 600 mm, a 1,200 mm cross tee is placed at right angles and a 600 mm cross tee is used to close the 600 mm modules (+4 Euroclips/panel).

Acoustichoc® Impact 15 ceiling: 1,200 x 600 x 22 mm

  • T24 or T35 runners should be arranged in parallel lines every 1,200 mm. Every 600 mm, a 1,200 mm cross tee is fitted at right angles.
  • You are advised to ensure that air can circulate between the rooms and the plenum to balance the temperature and pressures on each side of the ceiling.

To install an Impact 15 system, the following components are needed per m²:

Tiles Euroclips
600 x 600 x 22 mm 5.6/m²*
600 x 1,200 x 22 mm 4.2/m²*

* Number of clips per m² provided for guidance only; the exact number should be calculated according to the building's configuration.

The perimeter tiles have to be maintained by Quick-Lock® AC49 wall springs (1/tile).


  • The surface of Acoustichoc® Impact 15 ceilings does not retain dust, which makes them easier to clean.
  • Acoustichoc® Impact 15 ceilings can be cleaned using light brush / vacuum cleaner.
