The main parameter for the acoustical efficiency of the system is the clearance (h) between Cleaneo Acoustic Board and the non-perforated gypsum board.Note:
The suspension height of the system (space between Cleaneo Acoustic Board and basic ceiling) is of low influence for the acoustical efficiency. Therefore,different suspension heights can be used for the specified parameters.

Specifications for planning
n Perforation type: Standard Circular R/ Alter-nating Circular R/ Random PLUS R/ Standard Square Q/ Block Perforation/ Block Slots
n Separations (e.g. as exposed joints) within one room, especially when designing segments with continuous perforation.
n Fire resistance: F30 solely from below, F30 solely from below and from above.
n Color of fleece: white / black / other.n Perimeter: non-perforated perimeters with width
specifi cations according to page 4.
n Design of perimeter in room with/ without shad-ow gap, specified width.
Construction
Generaln Knauf Cleaneo Acoustic Boards are lined with
Knauf Standard Fleece (white or black), or spe-cial acoustical fleece on request. Other colors on request.
n The sound absorption diagrams of individual Knauf Cleaneo Acoustic Boards show values that are only valid in connection with Knauf Stan-dard Fleece linings.
n Knauf Cleaneo Acoustic Boards are perforated or slotted gypsum boards based on gypsum and zeolite, ideal for rooms to improve room climate and reduce air pollution.
n Loads directly anchored to Knauf Cleaneo Acoustic Boards are not permissible.
n Random PLUS: Certain view points in a room or unfavorable lighting may lead to a diminished vi-sual impression of a continuous perforation pat-tern caused by longitudinal joints.
n Depending on the direction of the light, a loom-ing of the furring channels can occur in connec-tion with white Knauf Standard Fleece and per-forations with diameter ≥ 10 mm.
n Separate gypsum boards from building elements made with materials other than gypsum, espe-cially columns, by creating control joints that al-low for movement, e.g. shadow gap.
n Settlement joints have to be transfered into the construction of the ceiling System.
n Use control joints in the case of ceiling areas over approx. 15 m length, or for narrow ceiling spaces caused by a break of a wall. For strongly structured suspended ceilings, additional control joints may become necessary.
n Knauf profi les are delivered galvanized. This corrosion protective coating is sufficient for in-door rooms, including bathrooms and kitchens in residential housing.
Knauf Cleaneo Acoustic Design Ceiling D127 n
n Knauf Boards are attached to a metal grid of car-rying channels and furring channels.
n Mineral wool mats with a minimal thickness of 20 mm can be placed on the furring channels.
Knauf Cleaneo Acoustic Fire Protection Ceiling D124n Knauf Cleaneo Acoustic Fire Protection Ceilings
as suspended ceilings consist of fire protection level and acoustic level.
n Fire protection F30 solely from below, or alterna-tively solely from below and from above, is pro-vided. The installation of Knauf access panels is possible.
n The fire protection level is anchored on the basic ceiling with Universal Brackets or Nonius sus-pension. Knauf Fire-Resistant Boards FR acc-
n The acoustical level is attached with Direct Brackets or Universal Brackets to the furring channels of the fire protection level.
Knauf Cleaneo Acoustic Boards are attached to a metal grid made of furring channels only or made of carrying channels and furring channels CD 60x27.
Knauf Cleaneo Acoustic Ceilings are anchored directly to the basic ceiling as a ceiling lining, or with suspenders as suspended ceiling.
ording to DIN 18180 / EN520 are screwed on a metal grid of carrying channels and furring channels CD 60x27 according to DIN 18182-1.

Cleaneo Acoustic Fire Protection Ceiling D124Fire protection level: Suspended with Universal
Brackets or Nonius suspension spaced at 650 mm max. Spacing of carrying channels and furring channels according to tables on pages 2,3 and 21.
For fire protection from above apply an additional layer of mineral wool, building material class A, den-sity ≥ 40 kg/m3, melting point ≥ 1000°C (1832°F), t ≥ 40 mm above furring channels and a min. 15 cm wide mineral wool strip on carrying channels.
Acoustic level: Suspended with Direct Bracket (single grid) or Universal Bracket (double grid). Max. load per suspension point: 100 N. Spacings of channels and suspenders according to tables on pages 2,3 and 21.
Apply mineral wool, building material class A, den-sity ≥ 40 kg/m3, melting point ≥ 1000°C (1832°F), t ≥ 40 mm for grid fastened with Universal Brack-et or t ≥ 25 mm Rockwool for single grid faste-
withned Direct Bracket along the entire ceilingarea. n Single grid (only one level of parallel channels):
fill channels with mineral wool strips and apply mineral wool fully between channels.
n Double grid (consisting of carrying channels and furring channels): fill carrying channels with mineral wool strips and apply mineral wool fully above furring channels.
Cladding
Knauf Cleaneo Acoustic Design Ceiling D127/Cleaneo Acoustic Fire Protection Ceiling D124Cross-mounting of Knauf Cleaneo Acoustic Boards (joint width 2 to 4 mm, depending on perforation pattern) laterally to furring channels, place front edge joints on channels. Sand down the face side square edges (SK) slightly with Sanding Mesh be-fore installing the boards.Knauf Cleaneo Acoustic Boards with standard or alternating perforation are color-coded in red and blue along the edges. Place red marking adjacent to blue marking along front and long edges. An in-stallation team with 3 workers is recommended.
Align Knauf Cleaneo Acoustic Boards using laser equipment or reference cord regarding continuous straight perforation rows beyond joints in diagonals and lateral as well as longitudinal direction.Use Perforation Aligner with knobs compatible to perforation pattern to check correct joint width (this does not replace aligning). Start fastening of Knauf Cleaneo Acoustic Boards either in the middle or at a corner in order to prevent upsetting deforma-tion. Press the boards firmly on to the grid during screw attachment. Fastening according to table on page 24. .
A seamless, non-perforated frieze with a minimum
width of 100 mm is recommended for irregular ornon-rectangular layouts of ceilings.
Jointing
Hand fill joints with Knauf Uniflott without using tape on 4SK boards. Use Fugenfüller / F2F and tape on 4AK boards. Cover all screw heads as well. Knauf Cleaneo Acoustic Boards: prime before jointing. Fill joints with Knauf Unifl ott using the tube of the installation set, skim with Knauf F2F in a second run. Possibly filled perforations can be cleaned
Filling and covering of joints should only take place after the boards have been allowed to rest in the given humidity and temperature zones, and no more longitudinal changes can be expected, i.e. expansion or contraction. Joints should be filled at a minimum temperature of 10°C (50°F). In case of mastic asphalt screed, fill in joints after screed has been applied.
Surface Treatment
Before applying paints or coats the fillled sur-face should be dust-free. Use a primer on Knauf Cleaneo Acoustic Boards before coating or paint-ing them. Ensure that the primer and the coat or paint are compatible.The following coats can be used on Knauf Cleaneo Acoustic Boards:n Coats: Resin dispersion paints, multicolored
(rainbow) emulsion, oil paint, matte-fi nish lac-quer, alkyd resin paint, polymer resin paint, PUR lacquer, or epoxy-based lacquer, according to intended use or as required.
n Alkaline coats such as lime, water glass paints and silicate-based paints are unsuitable for gyp-sum board surfaces.
n Silicate-based emulsion paints may be used after referring to the manufacturer’s recommen-dations and following the stipulated guidelines closely.
NotesIf Knauf Cleaneo Acoustic Boards are coated with diffusion open coats like dispersion paint, their air-cleaning effect will only be marginally reduced.
Gypsum board surfaces that have constantly been exposed to light without any protection can cause yellowing after coating. Therefore, a trial coat is recommended that will extend across several boards including all joints. Yellowing can, howev-er, be successfully avoided only by using a special primer.
using a Pilot Wheel compatible to perforation pattern before hardening of filling compound.
