3 . Introduction This publication provides basic information for the planning and installation of ceilingsystems. The information contained within this guide is based on our recommendations and those contained within the current European Standards (EN 3964). Inline with improving standards and techniques please make sure you are using the current* issues of both documents. As a manufacturer and supplier, we offer complete, tried and tested ceiling systems. OWA ceiling systems can be used to provide a variety of performances as well as aesthetic functions. In all cases the correct installation of the ceiling is essential to ensure that the ceiling can fulfil any such requirements. Where the OWA ceiling is to provide any level of performance it must be installed in accordance with the relevant test report, assessment or those recommendations provided by OWA. Failure to use the specified components or comply with the installation recommendations will invalidate any test report, assessment or warranty. *See back page for publication date 3

4 . Basics Technical guidelines Basic Planning An OWA ceiling is installed using dry construction methods and is generally for interior use only. The basic principles of dry construction should be applied when installing the ceilings. Where additional materials such as timber or gypsum are used, the guidelines on working with those products should also be observed. Site conditions Before installing an OWA ceiling the room/site conditions should be assessed. The area should be weather tight (windows and doors in place) and have a stable, dry environment. The ceiling should only be installed after the wet trades, such as plaster- and screed-work have been completed and the environment is dry and stable. Reference values for site environments Generally the relative humidity should be < 70 % RH (reference temperature 5 C), but it is recommended that installation should take place at temperature and humidity levels similar to those that will prevail during subsequent occupation. Standards for suspended ceilings EN 3964 Suspended Ceilings requirements and test methods, has now been accepted in most European countries as the prevailing standard and provides information for manufacturers,specifiers and users of suspended ceilings. Covering complete ceiling "Kits" and individual components it also provides test methods, methods of assessments and provisions for the evaluation for conformity of the products to the requirements shown in the standard. Quality Dimensions, material characteristics and colour are covered by EN 3964 Colour Allowable tolerances in shade of colour OWA white The difference in Δ E value within one production batch may not exceed a value of.0. Where the materials used are from more than one production batch the tolerance may be greater than Δ E =.0. Greater variation may be expected when installing materials purchased as individual orders over extended periods of time. Fire panels as building material Note: The word "panel" is used as a generic term within this document to describe tiles, planks and linear panels. Where more clarity is required the definitions shown in EN 3964 will be used. Reaction to Fire Classifications EN 350- When tested to EN 350-, building materials are divided into a classification ranging from A to F with A providing the best performance. As well as measuring a materials contribution to fire this standard has introduced criteria measuring smoke generation (s) and production of burning droplets (d). In most countries of the EC you will find tables that translate the previous class according to local standard to the relevant EC class. For countries outside the EC, please check your local regulations or call your nearest OWA office. The additional designations are: Smoke s, s, s3 s = little or no smoke generation S = medium smoke generation S3 = heavy smoke generation Burning droplets d0, d, d d0 = no droplets within 600 seconds d = droplet form within 600 seconds but do not burn for more than 0 seconds d = Not as d0 or d Country Test standard Classification Standards: See table in installation guide for mineral wool tiles! ceiling systems fall into Class A. Additional elements such as non-woven backings, insulation pads, foam strips, etc. may affect the material fire classification. Ceilings Structural components EN 350- considers a "building component" to be the 4

5 . Basics Technical guidelines complete construction of soffit/floor plus suspended ceiling and it is the complete construction that is subject to test. The total construction should prevent the passage of fire and provide effective insulation for as long as possible. It is therefore important to use the complete, proven, ceiling system where performance is required. Standards for the load-bearing building component: Soffit + Suspended Ceiling Fire Resistance with When used in conjunction with OWAcoustic panels fire resistance can be achieved using a number of ceiling systems. Independent fire resistant ceiling systems are also available. The performances shown in our test reports are only valid when systems, panels and components are used and installed in accordance with the relevant test report. zu Area schützender to be protected Raum Brandraum Fire Depending on their fire resistance duration, building components are divided into the following classes: Classification Resistance to Fire Duration according to EN 350- (minutes) REI REI REI REI 0 0 REI The fire resistance of structures in combination with suspended ceilings must be proven by fire tests according to European standards. Tests covering many typical constructions have been successfully carried out with OWA ceiling systems. The OWA fire resistance test results are only valid if complete OWA ceiling systems are installed. Fire resistance from above and below We have developed specialist ceiling systems that can be used to provide fire resistance from above and below achieving class EI 30 (a < > b) Brandraum Fire zu Area schützender to be protected Raum Sound ceiling systems can fulfill a wide range of functions relating to the control of sound. Optimising room acoustics In many rooms, the correct reverberation time T [s] is required for good comprehension of speech or appreciation of music. Similarly in noise-intensive production facilities or workshops, the greatest possible sound level reduction is required to make the environment more comfortable. Reverberation time regulation T desired [s] Noise level reduction Δ L [db] The four following standards contain the basics of measuring room acoustics. The requirements for specific applications depend on local or country regulations; we suggest you ask our local sales offices for guidance. EN ISO 354 Measurement of sound absorption in a reverberation room EN ISO 40 Measurement of sound insulation in buildings and of building elements EN ISO 338 Measurement of the reverberation time of rooms... EN ISO 0848 Laboratory measurement of the flanking transmission of airborne and impact sound between adjoining rooms Optimising building acoustics ceiling systems can be used to reduce and control airborne sound generated from the cavity and adjacent rooms especially when combined with additional infill elements, such as OWAcoustic mineral wool panels. This combination is even more important when using perforated metal panels. In the modified form the ceiling can be used to: enhance the airborne sound insulation Rw [db] of solid and wooden beam soffits 5

6 . Basics Technical guidelines improve sound insulation D n,c,w [db] between two adjacent rooms with a common plenum reduce noises from the plenum As installation conditions vary from site to site each project should be assessed on its own merits. Where the acoustic performance of a room is important it is recommended that a qualified acoustician be consulted. If you are looking for additional information on building acoustic requirements, we recommend you consult either ISO, EN or local standards and regulations: Of course you can always contact your OWA sales office for information. Planning before installation An inspection of the building site to check local conditions, site measurement of the rooms and production of an installation plan are important preliminary work steps. The ceiling layout, arrangement of lighting and similar matters must be determined with the architect. Structural physics basics: All planning relevant aspects, such as determining ventilation cross-sections, air exchange rates, arrangement of vapour barriers, humidity, feasibility of a soffit in the case of a ventilated ceiling with regard to the formation of any condensation in the building etc, must be determined by an expert planner (building physicist) and if necessary tested! Requirements regarding building physics, fire protection, acoustics or other matters, which could arise among other things from the relevant standards, have not been considered in this installation brochure. Perimeter panels The size of perimeter tiles will be dependant on the ceiling layout and may be dictated by the position of services, walls, partitions etc. as well as other aesthetic considerations. Generally perimeter tiles should be as close to a full module size as possible, and preferably larger than half a tile. In the example shown below we take room 3.0 metres wide and install 65 x 65 mm tiles. The recommended layout uses three full tiles and two cut perimeter tiles of 56,5 mm. This is preferable to other example which uses four full tiles and two cut perimeter tiles of 50 mm. The number of tiles is the same but the ceiling would require an addi- tional run of suspension profiles and be less aesthetically balanced. Example: 3000 mm , ,5 uneconomical tile distribution economical tile distribution Effect of light or lighting on the suspended ceilings For architectural and optical reasons, light striking the suspended ceiling at a shallow angle should be avoided. This refers both to light fittings and to glazed facades that extend up to the lower edge of the ceiling. Unfavourable incident light can emphasise and exaggerate any minor difference in levels or pattern even when this lies within the tolerance range. The installer can contribute significantly to the appearance of the ceiling by observing all of the manufacturer's recommendations. Tolerances: Mass produced ceilings are produced within tolerances that are deemed to be acceptable. These tolerances are shown in EN 3964 The European standard for suspended ceilings. Flatness: The manufacturing tolerances for thin gauge materials are shown in table 4 of EN "Squareness": The suspension system (main and cross sections) must be installed absolutely square. The permissible deviation depends on the dimensions of the ceiling membranes used and their attachment. A practical method to check the squareness of the modules is regular checking of the diagonals during installation and/or the correct fitting of the ceiling panels. The permissible deviation depends on the panel type, but even the slightest deviations from squareness may in practice lead to visible deformation of the panels. Alignment of panels: Suspension system, panels and any service elements included in the ceiling plane must be installed accurately and in accordance with the module specified. Care should be taken to ensure that the alignments of profiles are maintained especially at joints and intersections. 6

7 . Basics Technical guidelines Cutting to size of perimeter panels: Normally the ceiling layout will be based on the centre line of the room bisecting, or running along the junction of a panel. Unless otherwise agreed, whichever provides the largest perimeter panel is normally used. Ideally the perimeter panel should be at least half the size of the panel. When cut, installed and pushed over against the tee parallel with wall, at least 0 mm of the panel should be resting on the perimeter trim. Expansion and movement joints In small areas, temperature fluctuations due to solar gain or environmental variations rarely cause problems, however in large areas or those where materials with varying expansion coefficients have been used expansion or contraction may adversely affect the ceiling. In such cases special allowances should be made, especially at the perimeters. Where building expansion and movement joints have been included in the building design, these should be replicated in the ceiling membrane or suspended ceiling. Pressure and wind loads Closed room and buildings with open facades are just two examples where wind loading and/or air pressure within a room can create additional loads on ceilings. Where such problems can be identified additional measures must be taken to protect the stability and security of the ceiling and components within the ceiling plane. Load-bearing capacity All ceiling systems (suspended ceiling kits) shown in this guide have been tested for load-bearing capacity in accordance with EN As shown here Table 6 provides classifications of downward deflection with Class requiring a maximum L/500 deflection of 4 mm. When used in accordance with our recommendations OWAconstruct profiles meet the requirements of Class. Where you require performance data for other standards please contact us. Class Maximum deflection in mm L/500 and no greater than 4 mm L/300 3 No limit L is the span between the suspension components or suspension points Additional Loads OWAconstruct systems are designed to support the load created from the suspension system and ceiling panels. Additional loads such as recessed and surface mounted light fittings, air outlets, insulation quilt, curtain rails and partitions should be independently suspended. OWA may be able to provide effective methods of supporting some additional loads with minimum cost and disruption. No altered or adapted profiles (notching, drilling, etc.) should be used under load without prior consultation. 7

8 . Basics Technical guidelines Corrosion protection of profiles, hangers and membrane materials The humidity level within a room not only affects the membrane material but may also have an effect on the suspension system and associated components. These are generally manufactured from cold rolled steel and should have the correct level of corrosion resistance to match the proposed installation environment. Excerpt from EN 3964: The environmental conditions are defined in Table 7. Table 7 Classes of exposure Class A B C D Condition Building components generally exposed to varying relative humidity up to 70 % and varying temperature up to 5 C but without corrosive pollutants. Building components frequently exposed to varying relative humidity up to 90 % and varying temperature up to 30 C but without corrosive pollutants. Building components exposed to an atmosphere with a level of humidity higher than 90 % and accompanied by a risk of condensation. More severe than the above. In EN 3964 table 8 gives the minimum requirements for corrosion protection according to the classes of Table 7.

9 . Basics Technical guidelines Standard metal ceiling panels are made of sheet steel and have a ZE 5/5 electro-galvanised or ZE60/ZE60 hot dip galvanized surface. This corresponds to either corrosion protection class A or B of Table 8. subconstruction components have a 7 0 um zinc coating on all sides and therefore meet the requirements of both class A and Class B of the table 8. It is important to ensure that the corrosion resistant protection is not damaged before or during installation or later when in general use. Where components are cut or damaged they must be treated to ensure the required level of resistance is not compromised. Contact corrosion: Corrosion due to the interaction of different materials must be prevented by introducing the correct protective measures (as shown in EN ISO point 5.0). These should be identified prior to installation to prevent failure at a later date. Hangers and fixings to soffit or roof Hangers and fixings to the roof or soffit form the connection between the structure and ceiling. To comply with EN 3964 fixings should have European Technical Approval (ETA) and should be installed in accordance with the manufacturers instructions and the limitation of use observed. Transport and storage products must always be stored in a way that ensures they are not exposed to moisture, dust or mechanical influences. In addition, the following points must observed: In the event of delivery on pallets, the panels must be stored on the pallets until their installation. Cartons must always be stored with the designated side upwards. No foreign material may be stored on the pallets or the cartons. They may not be stepped on or used as a seat or ladder. When storing metal panels, care must be taken to ensure that the panels are not damaged by the supporting surface. Metal panel packages may not be stacked higher than m. Transport routes within the building site must be reduced to a minimum. As far as possible central storage places must be arranged on each floor. In the event of maintenance work care must be taken to ensure demounted ceiling panels are placed on one of their long sides and carefully leant against a wall, with the finished surface facing the wall. Panels are never to be stored on the decorative surface. Safety Thin walled materials must be handled with care to avoid personal injury and product damage. The installer must ensure that all associated risks are minimised and a full risk assessment carried out. Cleaning and care The standard finish for ceiling panels is an electrostatic polyester powder coating. Other types of finishes are available upon request. Normally our products do not need cleaning unless the room environment, climate control, ventilation or use makes the ceilings visibly dirty. Where this happens the following actions may be considered. For the cleaning of visible surfaces we recommend the use of mild, lukewarm, soapy water (standard household washing-up liquid) or diluted alcohol based window cleaning agent using a clean soft-fibre cloth. Finally the ceiling can be wiped over with a chamois leather. Any oily or greasy residues can be removed with white spirit, however, this has to carefully applied to avoid any detrimental effect on the sheen. In all cases we recommend that a small trial area be tested before cleaning the whole ceiling. Scouring agents are not permissible. Painting the ceiling is another possibility but should be carried out by professional painters. Again we would recommend a trial area as de-greasing or sanding may be required. Care should also be taken to ensure the reaction to fire classification is not affected. Painting is not recommended for perforated panels as the acoustic performance may be impaired. 9

10 . Basics Technical guidelines Environment and disposal The use of metal products provides an easy to recycle ceiling. Ceiling is ease to de-construct. Materials are easy to identify and recycle. Free from asbestos and formaldehyde. Recycling of packing material OWA in Germany have reached a recycling agreement for all packaging materials (cartons, pallets, PE foils ) with INTERSEROH AG, contract no A similar recycling organisation may be present in your country.

After the U profiles have been aligned in both directions, each U-carrier row is fixed to the wall using wall anchor No. 75 E. This wall anchor can be fixed to the side (as shown) or underneath the U profile. 9

20 clip-in systems S 3 concealed, demountable S 3 concealed, swing down Installation and removal of panels The panels for the clip-in systems are manufactured with pips on two parallel edges to provide a friction connection with the clip-in profiles. The panels are pushed into the clip-in profiles until an audible click is heard. The removal or swinging down of the panels is only possible with the special removal tool No The tool is pushed into the unclamped panel joint directly next to the clip-in profile. The spring hinge of the tool must be on the side of the panel to be removed. After the spring has clicked into place in the panel edge, the panel can be carefully withdrawn from the clip-in profile. The same procedure is to be applied to the other panel edges. Swinging down of panels Individual panels can be selected to swing down in system S 3. For this, the hinge-down clip No. 86 E, must be clipped onto clip-in profile No. 87 E at the panel joint. Both adjacent panels in the same row can then be swung down towards each other. If a hinge-down clip is likewise arranged on the next but one panel joint, an area the size of two panels can be opened in the ceiling by swinging down. Wind safety/ Security The panels can be secured against displacement e. g. in the case of increased wind pressure with the help of security-bracket No. 68 E. The security clip is inserted through the hole in the two adjacent panels and clipped over the clip-in profile. Two security clips are required per panel. Once secured the panels are not demountable. The hinge down clip used in System S 3 can also be secured using clip No. 86E0. Tiles can still be swung down. Perimeter options The distance between the upper U profile edge and underside of the ceilings panels is 96 mm and cannot be adjusted. This means that the perimeter trims have to be fixed precisely. No. 86E0 The following perimeter trim versions are available: C-perimeter trim No. 57 (steel, visible side white) in combination with wall spring No. 50 No. 68 E 96 The panels are provided with so-called hinge tabs at the clamped edges to ensure a neat panel joint. In the case of swing down panels, the hinge tabs in the region of the hinge-down clip must be bent. Hinge tabs Stepped perimeter trim No. 560 F (aluminium, visible side powdercoated white) in combination with wall spring No. 50 F-perimeter trim No. 50 F (aluminium, visible side white) in combination with wall spring No. 50 In the case of linear panels, it is the other way round, i.e. if they are not to be swung down, the hinge tabs have to be pressed inwards. System S 3 differs from S 3 only by every second panel joint being equipped with a hinge-down clip. As a result, all panels can be swung down. By gently pushing swung down panels together the open space can be made even larger. Panels which are supported by a perimeter trim cannot be removed directly or swung down. Consequently, in the case of smaller or narrow areas at least three panels per installation row are required so that initially the penultimate panel and then the wall panel can be demounted. See brochure 300 for additional perimeter trims and information on installation. 0

Versions: Dimensions: OWA-Lex OWA-Terra OWA-Opta 600 mm x 600 mm 65 mm x 65 mm Clean room ceiling When used in system S 3 plain un-perforated metal panels can be used to satisfy most clean room requirements (cf. OWA brochure No. 895 ceilings for clean rooms). Clean-room clamp No For details on installation and fire protection of lighting, see brochure No Down-lights: OWA supplies compatible down-lights for this system. For details on installation and provision of fire resistance for lights see brochure No. 63. Sealing tape No General notes: Clip-in panels with integrated lighting as a compact component are available for systems S 3 and S If the location point of the lighting to be installed is not known, connector clip No. E can be used as an alternative to Hanger bracket No. E provided the void height permits this. The distance between the top edge of U profile No. 70 E and the underside of the metal panels is then 46 mm instead of 96 mm. As a result most lighting can be installed irrespective of the location of the U profiles. For this it is necessary to slide on at least on clamp No per panel joint (see sketch) install wall spring clips on all perimeter panels using one clip 30 cm ( minimum per panel) to ensure where walls or partitions are uneven that the junction between the wall and trim is sealed using a suitable sealant (e. g. acrylic). Perimeter Options Perimeter Channel No. 57 with retaining spring clips No. 50 Perimeter trim No. 50F with retaining spring clips No. 50 Note: We can also provide clip-in panels with integrated clean room lighting (protection class IP54, see brochure 630). For more project specific information or guidance on the installation of clean room ceilings please contact OWA.

A hanger should always be positioned close to the joint and joints should be staggered. Expansion joint: Every main runner is equipped with a standard expansion joint at one end, which serves to accommodate linear expansion in the event of fire. Expansion joint The main runners must be so arranged that no expansion joints are adjacent to each other. No load transfers (hangers, light attachments ) are to be fitted to the expansion joint. 5 5 In conjunction with the main runner the cross tees are used to create the required module. They are equiped at both ends with off-set hook connectors that are inserted into the main runner slots. Care must be taken to insert the connectors in the correct side of the slot (see diagram above). ensure the cross tee expansion nose is not bent. ensure the visible surfaces of the profiles are flat and level. Cross tees No. 46 or No. 47 are off-set to the left. Cross tees No. 47 and No. 47/5 G are slotted in the middle for the insertion of additional cross tees. Perimeter cross tees are supported by the perimeter trim and should be cut short of the wall by 5 mm or /4 of the width of the perimeter trim, whichever is less. Additional hangers must be used to compensate for any additional loads placed on the cross tees. When setting up the first main runner row, it must be ensured that: the distance to the wall corresponds to the length (width) of the perimeter panel. the distance of the slot for the insertion of the cross tee to the wall corresponds to the width (length) of the perimeter panel. The main runners can be installed almost without waste, i. e. most off-cuts can be used at the beginning of the next row of main runners, automatically creating staggered joints (see previous). The main runners are 3

24 Lay-in Systems S 33 exposed, demountable, 4 mm S 45 exposed, demountable, 5 mm Perimeter options Depending on the edge detail of the panels, various perimeter trims are available: For edge 03 and edge 04 C-perimeter trim No. 57 (steel, visible side white) in combination with wall spring No. 50 F-perimeter trim No. 50 F (aluminium, visible side white) in combination with wall spring No. 50 Integrated lighting OWA supplies compatible integrated lighting for this system (OWA Lex, OWA Terra, OWA Opta) in the dimensions 600 x 600 mm and 65 x 65 mm. This lighting can be installed in place of a panel in the supporting structure. The lighting must be independently suspended or additional hangers must be installed to compensate for the additional loading where appropriate. Down-lights must in general be suspended independently. The required panel cut-outs can be included during manufacturing provided they are ordered together with the panels. For edge 07 F-stepped perimeter trim No. 560 F (aluminium, visible side powdercoated white) in combination with wall spring No. 50 F-stepped perimeter trim No. 505 F (aluminium, visible side powdercoated white) in combination with wall spring No. 50 F-perimeter trim No. 50 F (aluminium, visible side white) in combination with wall spring No. 50 Electrical cables are not to be laid onto the ceiling or suspension system. Coordination with the electrical planner or installer is important to enable the installation of additional or independent suspension. Experience shows that the installation of hangers retrospectively is more difficult, more expensive and they are therefore more likely to be omitted leaving a potentially serious, concealed defect. Depending on panel-type and perimeter trim, the main runners and cross tees may have to be suspended near the walls when they run above the perimeter trim. Correct installation of the edge panel in combination with F-perimeter trim and wall spring See brochure 300 (price list) for additional perimeter trims and information on installation. 4

There is no additional adjustment possible. The clip-in profiles can be shifted +/- 0 mm horizontally. Note: In some panels the tabs stamped into the ends of the panel s long side have to be pressed inwards. Installation and removal of panels The panels for the clip-in systems are manufactured with pips on two parallel edges to provide a friction connection with the clip-in profiles. The panels are pushed into the clip-in profiles until an audible click is heard. The removal or swinging down of the panels is only possible with a special tool, the removal tool No The tool is pushed into the unclamped panel joint directly next to the clip-in profile. The spring hinge of the tool must be on the side of the panel to be removed. After the spring has clicked into place in the panel edge, the panel can be carefully withdrawn from the clip-in profile. The same procedure is to be applied to the other panel edges. Swinging down of panels Individual panels or all of them can be selected to swing down in system S 36. For this wire clip No. 69 E, that serves as hinge, must be introduced into the hole on the panel s long side and clipped onto the clip-in profile No. 87 E (see illustration). Up to three swing down panels can be pushed next to each other on the clip-in profile to enlarge the opening area. If the wire clips are arranged on the panel s joints opposite each other, a ceiling area twice as big can be opened thanks to the swing down action in opposite directions Panel length 8-38 Minimum suspension height: The carrier angles can be mounted directly under the soffit. Please take account of possible lighting height. Note: Panels cannot be removed when in the swung down position. Where a panel is to be removed the wire clip No. 69 E must be un-clipped before the the panel is moved 5

Extend sliding coupling until they click into place and rest them on the G section. Panel is now in the swing down position. Carefully push the other edge of panel up until the spring clips into place (for ease of installation it may be necessary to depress the springs). Swing down/demount: To swing down or demount the panel, removal tool No is required. Insert removal tool No between the G-section/ panel and locate spring clip. Slide the removal tool along either side of the panel until the spring clips have been compressed and the front edge of the panel freed. Gently pull the panel down into the the "swing down" position. To remove completely retract the sliding couplings and remove panel. Removal tool, putty knife etc 6

When this distance is less than mm wall anchor No. 75 E or bracket No should be used. Version 3 Metal panel Version : U profiles No. 70 E are fixed to the wall using wall anchors No. 75 E. When using this version the distance between the wall and panel is not critical but must be sufficient to allow installation of panels. U profiles No. 70 E are connected using splice No. 77 E (see page 3 for details). Bracket No. E0 with safety clip No. 66 E Bend down flaps to secure 90 E to 70 E Z-profile No. 90 E U profile No. 70 E Splice No. 5 E Z profiles are fixed to the U profile using connector bracket No. E0 secured to the U profile using safety clip No. 66 E. Once the Z profiles have been located in the bracket the locking flaps should be bent down to secure the Z. When using wall anchor No. 75 E or bracket No use M6 nuts and bolts to connect the Z profiles. It is important to ensure that all the profiles are installed accurately and level. Version 3: L profile No. 50 E is fixed to the wall at the appropriate level and the Z profile bolted below using M6 nuts and bolts at 50 cm centres. Both profiles are supplied with predrilled holes at 50 cm centres. The L profile is 45 mm wide and allows panels to be removed but not hinged down. Hinge down and/or remove panels To install or remove the panels there must be a minimum distance between the panel and the wall of at least 0 mm one end and 5 mm the other. To allow the panels to hinge down there must be a minimum distance of 40 mm between the wall and panels. > 0 > 40 min. 5 Hinged down panel 7
