Determination of the weight of the ceiling lining / suspended ceiling depending on thickness of claddingDepending on the chosen thickness of cladding in mm (x-axis) the weight per unit area of the ceiling lining / suspended ceiling including grid and suspension can be read off from the y-axis at the intersection point with the marked diagonal

2. Consideration of extra loadsExtra loads from insulation required for fire protection from insulation not required for fire protection (0.05 kN/m² = 5 kg/m² max.) andas well as extra loads from system "Multi-level Ceiling" (0.15 kN/m² = 15 kg/m² max.) increase the total weight per unit area of the suspended ceiling / ceiling lining and should be taken into account for the load class determination. The determined intersection point fromthe 1st step has to be parallel-shifted by the rate of the extra load in direction of the y-axis (upwards).
3. Determination of the load classThe load class (kN/m²) can be determined with the resulting total weight per unit area of the ceiling lining / suspended ceiling from steps 1 and 2.
4.Depending on fire protection requirements and load class the following spacings of the substructure are specified: a b c

Multi layer cladding
In case of multi layer cladding, apply layerswith staggered joints according to applicationscheme.Press boards of each layer firmly on to the substructure and screw each layer separately.For fastening of first layer, spacing of screwscan be increased up to max. 500 mm (for cladding thickness 25 + 18 mm/ 2x 20 mm up to max. 300 mm according to installation scheme on page 19) if second layer is applied immediately afterwards (within one working day).In case of multi layer cladding, a filling of jointsof first layer without further finishing is sufficient.

Suspended ceilings in connection with basic ceilings of type I to III as well as suspended ceilings for fire protection solely from belowand / or from above that are fire rated F30 to F90 can be connected to partitions if they are of the same fire resistance class .
Surface of partition should be even in the area of the connection. Specific levelling preparations might be necessary.The connection of the board ceiling has to be tight and covered.
Fire protection from below and from above / from aboveFire protection from below
with at least 15 mm allowable movement.
For suspended ceilings with fire protectioninstall a deflection head as standard implementation
from below and from above /cladding to UW runner, but apply cladding tightly up to ceiling.For suspended ceilings with fire protection do not fastenfrom below
Connections of partitions to classified ceilings (board ceilings) are only allowed if it is ensured that in case of fire and a premature collapse of the partition, the debris pieces of the partition may fall down without additional loading of the ceiling.
The following solutions are optional for the connection:
In case of fire protection requirements for the partition the suspendedceiling should have at least the same fire resistance.

D11 Knauf Board CeilingsConstruction, Application
Construction
Knauf Board Ceilings are anchored directly to the basic ceiling as a ceiling lining, or with a suspen-sion as suspended ceiling.Knauf Boards are screwed on a metal grid made of carrying channels and furring channels (D112)or on a flush metal grid made of long and cross channels (D113).Select board type considering technical and build-ing physical requirements.
Settlement joints have to be taken over into the construction of the ceiling system.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. Separate gypsum boards from building elements made with materials other than gypsum, especial-ly columns, by creating control joints that allow for movement, e.g. shadow gap.
Knauf profi les are delivered galvanized. This cor-rosion protective coating is sufficient for indoor rooms, including bathrooms and kitchens in pri-vate housing. For other areas, e.g. exposed to out-door air, additional corrosion protection is neces-sary (see DIN 18168-1 table 2).

D11 Knauf Board CeilingsConstruction, Application
Construction
Knauf Board Ceilings are anchored directly to the basic ceiling as a ceiling lining, or with a suspen-sion as suspended ceiling.Knauf Boards are screwed on a metal grid made of carrying channels and furring channels (D112)or on a flush metal grid made of long and cross channels (D113).Select board type considering technical and build-ing physical requirements.
Settlement joints have to be taken over into the construction of the ceiling system.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. Separate gypsum boards from building elements made with materials other than gypsum, especial-ly columns, by creating control joints that allow for movement, e.g. shadow gap.

D11 Knauf Board CeilingsFastening of Loads, Jointing, Surface Treatment
Fastening of loads to Knauf Board Ceilings
Ceiling lights, curtain rods etc. can be fastened to board ceilings using universal dowels, cavity dowels or toggles.Single loads fastened directly to the cladding should not exceed 0.06 kN per span width of board.
Additional loads (extra loads like ceiling lights, curtain rods etc.) have to be considered for the calculation of the total ceiling load according to diagram on page 2 or should be fastened direct-ly to the basic ceiling.
In case of fire protection the fastening of loads to cladding or channels is not permissible, fastening of loads only to basic ceiling.
Jointing
Filling compounds
●with Joint Tape: hand filling with Knauf Fugenfül-ler / Uniflott / Knauf Readyfix Joint Compound
●Knauf Uniflott impregnated is the system filling compound for impregnated Knauf Boards. I t is
water-repellent and matches the color of impreg-nated Knauf Boards
● use Knauf Readyfix Joint Compound for thefinal filling coat as fine skimming before sandingthe joints
Application● for multi layer cladding, fill in joints of first layers,
smooth joints of top layer● fill all visible screw heads as well●Recommendation: Fill cut edge joints of visible
layers using tape no matter which filling material is used
●use Knauf Spezialgrund to prime the entire sur-face of filled Knauf Boards to control suction and for optical harmonization of the surface. Knauf Spezialgrund is a system component for the creation of surfaces with higher quality require-ments
●quality standards Q1 to Q4 according to Code of Practice no. 2 “Verspachtelung von Gipsplatten - Oberflächengüten” of the IGG
Application time / climate●Filling of joints should only take place after the
boards have been allowed to rest in the given hu-midity and temperature zones, and no more lon-gitudinal changes can be expected, i.e. expan-sion 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 filled surface should be dust-free. Use a primer on Knauf Boards before coating or painting them. Ensure that the primer and the coat or paint are compatible.To settle the different suction properties of the filled areas and the paper surface, primers like e.g. Knauf Tiefengrund/ Spezialgrund/ Putzgrund are suitable.In case of wallpaper lining a primer that allows an easier removal of wallpaper for redecoration is rec-ommended. After wallpapering or plastering ensure adequate ventilation for fast drying.
The following coats can be used on Knauf Boards:
Wallpapers: paper-, textile and synthetic wallpa-pers. Use only adhesives made of cellulose ac-cording to Code of Practice no. 16 “Technische Richtlinien für Tapezier- und Klebearbeiten”, Frankfurt/Main 2002, released by Bundesauss-chuss Farbe und Sach wertschutz.Plasters: Knauf structured plasters, Knauf indoor plasters, Knauf Acoustic Plaster, entire surface smoothing like e.g. Knauf Readyfix, mineralplasters in connection with paper taped jointing.
Coats: Resin dispersion paints, multicolored (rainbow) emulsion, oil paint, matte-finish lac-quer, alkyd resin paint, polymer resin paint, PUR lacquer, or epoxybased lacquer, according to in-tended use or as required.
Alkaline coats such as lime, water glass paints and silicate-based paints are unsuitable for gyp-sum board surfaces.
Silicate-based emulsion paints may be used af-ter referring to the manufacturer’s recommen-dations and following the stipulated guidelines closely.
Gypsum plasterboard surfaces that have constant-ly 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 spe-cial primer.
