1� General information on installation

OWAplan is a special high-quality ceiling system whose appearance is largely determined by the installation of the grid and plaster system� Installing and covering this ceiling system requires appropriate experience and knowledge in seamless plaster-covered ceilings� OWA therefore offers a training course on how to install an OWAplan ceiling� The training course covers the entireprocess, from assembling the grid, fitting the mineral boards, taping and jointing, to the various plaster coatings� If the installation of the grid and the mineral boards is not to be carried out by a certified coating company, detailed and extensive step by step instructions must be provided in advance by the responsible technical advisor or OWAplan technician, Kevin Fischer� Training dates need to be arranged in good time with OWA� Contact by telephoning: +49 9373 201-450 or -304� Since this is a certified building product training can only be provided if all system components being used are OWA products�

Classification of fire behaviour as a building product OWAplan seamless acoustic plaster ceiling S 7 has been classified as A2-s1,d0 - non-combustible in compliance with EN 13501-1 and is CE marked as a ceiling-KIT� The quantities to be applied as specified in the relevant test report and the system components listed there must be adhered to and applied� If other non-tested system components are used, the system characteristics of the OWAplan70/90 building product cannot be guaranteed�

Labelling in accordance with the Construction Products Regulation (EU-BauPV) S 7 OWAplan has been tested and labelled in accordance with the Construction Products Regulation no� 305/2011� The requirement for a Declaration of Performance (DoP) is therefore satisfied for the grid, the mineral board and the plaster system� You can find the DoP number on the respective packaging� Plaster system OWAplan S, whiteOWAplan XS, whiteOWAplan color, RAL/NCS colour on request Further information on the plaster systems and their applications is available on request or can be obtained from our video “Installation - system S 7 / OWAplan“ on the website www�owa-ceilings�com

Handling, transport and storage of the mineral boards Board boxes should only be transported horizontally by 2 people� Do not place on a corner or edge when setting down� Store in a dry place on a level surface, do not place on damp ground� The boards always lie in the packaging with the visible side facing upwards� There is a cardboard interleaf between each board for protection� The cardboard packaging should be carefully cut open and removed without damaging the board� It is advisable to also cut open the cardboard packaging at the front sides so that the cardboard packaging opens completely� It is always advisable for 2 people to remove each board from the packaging, one at each end, to prevent damage to the board edges, corners or the visible face�

2�1 Requirements prior to installation of the OWAplan ceiling:

– The area for installation must be dry�– EN 13964 stipulates site conditions should be > +7 °C� The coating could be applied at a temperature of up to +5 °C� – Relative humidity must not exceed 70 %�– System-compatible original construction parts must be used�– All layout plans including the required fittings must be available prior to commencing work�– All wall connections are to be executed in a flexible joint design�– Existing building expansion joints are to be incorporated into the OWAplan ceiling�– All fittings that may be required must be provided prior to installing the OWAplan boards� This requires coordination with

drywall workers, electricians and other participating tradespersons�– Taping and jointing and plaster coating must to be completed by a certified contractor only� The certificate needs to be verified

during the tender phase (refer to section 1)�– Higher quality standards regarding surface properties, e�g� using a suspended ceiling in poor daylight or artificial light

conditions, must be agreed in advance�– Artificial lighting directed at the ceiling surface from below or from the side (e�g� spotlights, indirect lighting) is to be avoided�

If this is not possible, the ceiling is to be sanded, filled and coated under the lighting conditions prevailing in subsequent use� Such extra quality standards for the surface are to be agreed in advance�

If fire safety is a requirement, the maximum spacing for the main tees, nonius hangers and tile screws specified in the test report, and the minimum suspension depth, must be adhered to. Furthermore, installation with a shadow gap is not permissible.

6 OWAplan

2�2 Requirements during installation of the OWAplan ceiling:

– The installed ceiling system (grid and OWAplan70/90 boards) is to be approved by the coating company prior to coating� Any re-working requested by the coating company must be carried out�

– All drying times for the plaster system must be observed�– All fittings are to be additionally suspended from the raw ceiling�– The room temperature, humidity and the outdoor temperature should be recorded daily during installation�– If installation work is hindered by external influences for which the contractor is not responsible, or if installation conditions,

drying times etc� specified in these installation instructions are deviated from, concerns must be made in writing to the client� (German Construction Contract Procedures (VOB) /B §6)

2�3 Final inspection of the OWAplan ceiling

Final inspection for evenness and surface quality may only be carried out under diffuse light conditions and not under artificial light conditions, e�g� from construction site lighting� It is not always possible to make joints invisible� Minor deviations (within the tolerance limits) may become visible in light coming from the side�

Unusual lighting conditions within the building must be discussed beforehand with an OWAplan specialist�

4�4 Installation of the OWAplan70/90 boards

Prior to installing the OWAplan70/90 boards, the fleece must be removed from around the perimeter of each board, on site, using a one-handed plane, approx� 30mm wide� The boards are installed using screws (no� 2019) at max� centres of 300 mm or 400 mm, depending on grid orientation� Penetrations or openings that need subsequent sealing are to be sealed using the relevant OWAplan board parts� Attachment to the CD

profiles is always from the centre of the board outwards� The screw heads must be recessed 5 - 8 mm below the visible face of the OWAplan boards (see detail on “Fitting the screws”)�

Note: always install the longitudinal edges of the boards in the direction of the incidence of daylight (main light direction).

During installation, the flatness tables 1 - 3 according to DIN 18202 (tolerances in building construction) must be observed�

Install the boards as running bond (offset joint gaps), with at least 800 mm offset� Approx� 30 mm of fleece on the cut edge of shims installed at a subsequent board must be removed� This can be performed using a single-handed plane (e�g� the “David combischaaf 647104” brand)� Shims of less than 800 mm are not to be used�

Any lines used for guidance during board installation must be made using a laser device� Drawing lines on the fleece of the OWAplan board with a pencil or similar is not permitted� Such lines cannot be removed on finishing and may be visible through the plaster coating�

Note

When using a board lifter, ensure that no pressure points are created in the base board otherwise the OWAplan board will exert excessive pressure against the CD profile construction�

Using a helmet to support boards during installation may produce indentations which will be visible later� This is therefore to be avoided� The boards need to be treated with great care�

4�5 Comfort access flaps no� 8031/9, no� 8031/10, no� 8031/11 and no� 8031/12

OWAplan boardNo. 8031/11 (340 x 340 mm) for 25 mm OWAplan90 boards, excl. OWAplan boardNo. 8031/12 (540 x 540 mm) for 25 mm OWAplan90 boards, excl. OWAplan boardHangers required, see section 3�4

The following points need to be considered: – The exact location of the access board needs to be aligned to the grid of the suspended ceiling�– The Nonius hangers must be installed according to the size and weight of the planned access flaps (see ceiling plan)�– The size of the ceiling opening must match the exterior dimension of the access flap to be installed�– The access flaps need to be installed prior to board installation�– When using access flap no� 8031/10 resp� no� 8031/12, the CD profile around the hatch needs to be removed� Two CD profiles

(length = 1000 mm) also need to be installed and suspended from the raw ceiling (see ceiling plan 540 x 540 mm)�– The OWAplan70/90 mineral board must be cut to the size of the inspection hatch on site� Using the one-handed plane, create

a circumferential fleece-free edge of approx� 30 mm around the tile before gluing with adhesive no� 99/24 into the lid of the inspection flap�

– Using the one-handed plane, create a fleece-free edge of approx� 30 mm around the perimeter of the cut-out before installing the inspection hatch�

– Before filling, OWAplan Tape must be applied within the fleece-free edge (both for the ceiling cut-out adjoining the inspection hatch and for the ceiling tile located in the lid of the inspection hatch)�

4�6 Mounting frame no� 8069/6

When installing downlights, mounting frame no� 8069/6 (two-part) is to be used� One mounting frame is required for each downlight� The frames must be placed with their edges on the CD profiles� Spacing between the frames depends on the diameter of the chosen downlight�

Ensure that the clamping device of the downlight later rests on the frame and that the mounting frame does not project beyond the edge of the hole� The opening for the downlight can be created with radius cutter no� 99/16� The size is to be adapted to the diameter of the downlight� Install before mounting the board!

Downlights each weighing 250 g - 2�5 kg require installation with a frame� Downlights weighing more than 2�5 kg each require additional suspension from the raw ceiling�

Electrical wiring is to be carried out before sealing the ceiling� Cables are to be kept to the length required� Light functioning is to be checked prior to installation because later modifications will not be possible�

If there are fire protection requirements, all components must be equipped with fire boxes - please refer to section 5 of these installation guidelines�

7�1�2 Description for coating

Before applying, note the following:– According to EN 13964, the site conditions must not be < +7 °C and > 70 % humidity�– During the application and drying phase, the ambient or substrate temperature must not fall below +5 °C and or rise above

+30 °C�– Excessive filled surfaces can reduce the absorption properties of the ceiling boards�– Any existing, coarse unevenness in the ceiling surface must be re-sanded with a long-neck sander, fine unevenness with a

hand sander�

On day one, apply OWAplan Tape over the board joints within the fleece-free edges� Fill the board joint gaps with two layers of OWAplan Filler and allow to dry� Drying time between the two layers at least 4 hours (may vary depending on the room temperature)� The width of the abutting fleece-free panel edges may be a maximum of 90 mm, the edge area a maximum of 45 mm� The screw heads are also to be filled� The next day, or after 18 hours at the earliest (may vary depending on the room temperature), sand the ceiling surface, vacuum and then apply the first layer of OWAplan S plaster� Drying time is at least 12 hours�

On the final day, spray on two layers of OWAplan S plaster with a drying time of approx� 4 hours between the two plaster layers�

Recommended spraying distance to the ceiling approx� 70 cm� Smaller distances lead to a cloudy and coarse spray pattern� Larger distances lead to a finer spray pattern, but also result in a high level of material spillage�

7�1�3 Application quantity / basis weight (wet application) OWAplan S, white on plaster base plateApprox� 1,2 kg/m², depending on structure and design�

7�1�4 OWAplan S, white plaster applicatorThe equipment required to apply our OWAplan S plaster is a screw pump system� The delivery rate must be between 4 and 8 litres per minute� The STROBOT 305 RSD is recommended�

In addition, a compressor is required which has a flow rate of at least 455 litres per minute and achieves a pressure of 10 bar� Since the pressure is not constant during the coating process, the flow rate is decisive� The STROCOMP 865 is recommended�

The diameter of the spray gun nozzle should be 4 - 5 mm� The smaller the diameter, the finer the plaster finish, but there is greater risk of nozzle blockage with a smaller nozzle�
