4 General Remarks for planning and handling Planning Preparatory measures The structural requirements of existing and new buildings must be matched with the requirements of the ETICS. Coordination of eventual preliminary tasks is to be settled with construction management. For all connections and details definite and realizable finishing information is mandatory. Sandwiching of existing ETIC systems is possible in accordance with building inspection approval Z Facade insulation should begin at least 20 cm below basement ceiling to avoid thermic losses via basement ceiling. Optimal would be to install an additional plinth insulation. To fasten components to the ETIC system the appropriate mounting elements must be taken into account. Existent structural expansion joints are to be realized in the ETICS as well. Interior plaster and screed must be poured, applied and dried. If required, appropriate measures have to be taken for drying. Cause for ascending humidity must be remedied. All horizontal coverings, e.g. window sills and roof closures must be installed prior to beginning with insulation procedures. When using EPS panels with thickness > 100 mm all lintels must be insulated with mineral wool panels of at least 20 cm width for reasons of fire safety (see detail planning 3.5.1, 3.5.2). For EPS insulation panels with thickness > 100 mm up to max. 300 mm mineral wool lintels may be omitted if for at least every second floor a horizontal circumferential fire barrier is installed. The fire barrier must be realized with a 20 cm wide mineral wool insulation band which is fully bonded and additionally dowelled. The distance between lower edge of lintel and lower edge of fire barrier may not exceed 0.50 m. (see detail plan 3.5.3) Abutments between cladding and ETIC must be realized rain- and windproof. In accordance with RAL guidelines all required sealing foils for mounting windows must be applied in the interior. The surfaces of sealing foils applied from the outside must be bondable as any other foils impair functionality of insulation panels. Installation of roller shutter boxes into an ETICS with EPS-Panels is to be evaluated individually. Only closed systems may be installed. Mixed systems with components of other systems are not permissible and void manufacturer s warranty. Fire prevention measures Windows Systems Levelness of substrate must accord to DIN Minor unevenness of the surface can be compensated for with the adhesives. The substrate condition must be examined by the processor before beginning with insulation measures. 3

5 Processing Dowelling Close expansion joints between insulation panels with insulation material strips. For further information see the General Construction Approvals. Trim height differences between insulation panels. Remove grinding dust completely. No expansion joints of insulation panels over structure joints. For joints between e.g. 3-layer panels or cracks a displacement of approx. 20 cm is advisable. Fill cavities under ledges with insulating material. All connecting joints and penetrations of the ETICS are implemented driving rain proof with KEIM joint sealing tape. The reinforcement layers and finishing plaster are to be separated from adjacent components by a trowel cut or suitable plaster parting strips. For suitable substrates systems with EPS panels may be realized fully bonded. Structural dowelling is implemented with e.g. 8 concrete dowels / m². Systems with mineral wool lamellae may be fully bonded to suitable surfaces for maximum expected wind suction loads of 1.6 kn/m². Surfaces not suitable for full bonding additionally require generally approved dowels with 140mm plates. Decision for type of dowel use depends upon the choice of ETIC system and wall material. The length of the dowel is mandated by anchoring depth, thickness of insulation panels, thickness of existing plaster and thickness of adhesive layer. Facades exposed to high pressure or mechanical stress, e.g. in playing areas, may be additionally reinforced with KEIM Panzergittermatte (Armoured wire mesh) or KEIM TEC-Platten (Panels). During the whole processing and drying duration the air and substrate temperatures must be at least +5 C. For KEIM Indusil the minimum temperature starts at + 8 C. EPS panels are to be protected from sun, and mineral wool and Multipor insulation panels from moisture. A suitable measure for that would be to cover the scaffolding. The reinforcement layer must have completely set before application of finishing plaster. Drying time depends upon weather conditions. To avoid visible transitions enough processors are required per scaffolding layer. The finishing coat is applied wet in wet. Larger areas should be adequately partitioned to permit uninterrupted application. Observe weather conditions. Due to environmental influence mineral and silicate plaster may dry cloudy. This is no technical defect and represents no reason for warranty. For visual reasons therefore at least one application of KEIM Egalisationsfarbe (Equalising paint) is required. For high quality finish a two-coat application of KEIM Soldalit is recommended. For AquaROYAL- System a two-coat finish of AquaROYAL- Color is compulsory. Shock-resistant ETICS Processing conditions Dowelling of insulation panels is performed underneath the fabric after sufficient drying of adhesives. For the Keramik-MW system (Ceramic) dowelling is performed through the fabric. 4

6 Application of glued and dowelled systems 1 Substrate must be solid, stable, dry and free of contaminants. Substrate requirements 2 Priming Pretreat absorbing and sanding surfaces with KEIM Indulaqua, a watery special primer. 3 Plinth profile KEIM plinth profiles are fixed to a plane surface with 3 dowels per m. The joints of the plinth profiles are connected with plinth profile connectors. By using the part of the system plinth plug-on profile unattractive fabric overlappings are avoided. 4 Glueing EPS panels The system-compliant adhesive mortar is applied to the EPS-panels using a bead-point-method. 40% of panel surface must be bonded to the substrate. 5 Glueing MW panels For uncoated insulating mineral wool panels the system-compliant adhesive mortar is first applied in a thin wetting layer and then wet in wet using a bead-point-method. 40% of the panel surface must be bonded to the substrate. 6 Glueing MW-Lamella Using coated lamellae S2, the systemcompliant adhesive mortar can be applied to the wall by machine and combed with a notched trowel. Lamellae S2 is to be bonded full-area to the substrate. 5

7 7 Glueing Multipor panels The XPor-Leichtmörtel (Lightweight-mortar) is applied to the Multipor Mineraldämmplatten (Mineral insulation panels) as full wetting layer or in bead-point-method. 70% of panel surface must be bonded to the surface. 8 Inserting insulation panels Insulation panels are inserted and pressed on flush. Sufficient bonding to substrate must be ensured. 9 Insulating panels in an offset pattern The insulation panels are closely abutted and glued in a bond pattern, avoiding cross joints. Special care should be taken not to get any adhesive between the panel joints. 10 ETICS compatible ledges Ledges must be compatible to the ETICS and installed prior to insulation measures. The ledge must project 4 cm over the completed ETIC-system. The use of window ledge brackets is advised. The end caps compensate for expansion and movement of the ledge. 11 Connection joints Connection joints between ledge and insulation panels are implemented with KEIM Fugendichtband (joint sealing tape). Panel cut-outs are made with KEIM Konturenformer (contour shaper). 12 When using plinth profiles as vertical edge the profiles must be installed with overlap. Vertical edges 6

Tropfkantenprofilen verstärkt Fire stops are installed horizontally around the whole building at least at every second level. The fire stop must consist of a 20 cm wide strip from a mineral wool insulation panel which is completely glued and dowelled. The maximum distance between lower edge of lintel and lower edge of fire stop may not exceed 50 cm. Edges in immediate proximity of openings are protected with fabric corner angles. See detail planning Joint gaps are implemented with KEIM Apu-Gewebeleisten (Fabric strips) between cladding frame and ETICS. 7

9 19 Reinforcement At joints the KEIM Glasfaser-Gittermatte (Glass fibre mesh) is embedded centred or in the upper third with an overlap of 10 cm depending upon employed system. Remove spreader ridges after drying. Within the reinforcement layer a trowel cut is performed at joints between adjacent components. 20 Finish coats The desired finish coat is applied by hand or by machine drawn to grain and evenly structured. Different grain-sizes, structures and colours are available. The light reflectance value (LRV) of colours should be > 20 for textured plasters and > 30 for smooth plasters. 21 Creative accents by KEIM Creative designs with KEIM glaze painting technique, KEIM façade profiles and KEIM structured panels (KEIM Boss panels) for insulated facades. 22 AquaROYAL AquaROYAL EPS und AquaROYAL MW The innovative solution with hydro-active ETIC systems without biocides. 8

10 ETICS wind suction loads Determination of dowels for statically relevant dowelling of ETIC systems Wind zone map DIN 1055 divides Germany into 4 wind zones: Wind zone 1, Inland Wind zone 2, Inland, Coast and Baltic Islands Wind zone 3, Inland, Coasts and Baltic Islands Wind zone 4, Inland, Coasts and Islands of North and Baltic Sea Wind zone 4 Wind zone 3 Wind zone 2 Wind zone 1 Standard Method Simplified approach The wind pressure and the resulting areas of differing wind suction loads must be determined individually for every side of the building. The areas A- B-C-E with respective dowel numbers are determined by the building dimensions. It is not required to calculate the area D. The regional positioning of the building, land formation and building height must be accounted for during calculations. To determine the number of dowels different methods are available. Engineering approach for calculation of surface areas in dependence of building height. Real calculation, possibly lower number of dowels, but division of building into areas A, B and C, with differing numbers of dowels. Simple handling resulting in consistent amount of dowels for the complete building. Max. height of building 25 m, from ground to ridge Side of the building max. double height to width (h/d < 2) Wind zones 1, 2 or 3 1. Determine wind zone, see wind zone map 2. Determine wall material 3. Determine type of insulation panel and thickness, determine ETICS category (Table 2) 4. Determine type of dowel and resulting dowel load category (Table 3) 5.

12 KEIM Rail systems With these systems the insulation panels are fastened with fastening strips. This applies to panels of EPS and mineral wool. For proof of stability the rails must be mounted with officially approved collared dowels. Choice of dowel type depends upon wall material. Substrate must be dry, stable, dust- and oil-free. Unevenness of up to 3 cm/m of the substrate can be compensated for with spacers. The insulating panels are additionally mounted with officially approved dowels required by technical approval Z Insulation panels in window and door frames are fully glued and additionally dowelled if possible. Near to end surfaces the M-panels are additionally secured with dowels. Where fastening strips cannot be horizontally mounted, e.g. roof connections, ledges, overhanging or projecting components, etc. a fastening strip is cut to length and mounted vertically. Should panels be cut to length the groove is created with a plough plane. Handling information Handling of KEIM Railsystem PS 1 Mounting plinth profile At the beginning of the rail system the plinth profile is mounted with 3 dowels/m.

16 KEIM perimeter and plinth insulation: Effective protection against thermal bridges General remarks Plinth recess KEIM perimeter and plinth insulation are a sensible enhancement of KEIM ETIC systems. Thermal bridges in height of the basement ceiling are prevented and building structures are effectively protected from the beginning. If ETICS are used and mounted in areas close to the plinth or having ground contact mechanical and humidityrelated stress-effects must be observed. Structural waterproofing must be ensured by sealing according to DIN In accordance with DIN all enclosing walls of a building having ground contact must be sealed against ingress of moisture. The vertical seal is implemented from the foundation up to the top of the horizontal seal, at least 30 cm above ground level. Surfaces to be sealed must be dry, clean, stable, and level (see DIN ). Expansion joints of the building are to be implemented in plinth- and perimeter-insulation. Precipitated water must be diverted away from the facade by structural measures. These are commonly a gravel layer or anticapillary layer. Pavement or stones must be implemented structurally separate from the building and with sufficient downward slope away from the building. It is possible to implement a plinth recess. A baseboard is installed between plinth and facade insulation. The joint between plinth insulation panel and baseboard is implemented with KEIM Fugendichtband (Joint sealing tape) The joint between plinth insulation panel and facade insulation panel is reinforced with an additional strip KEIM Glasfaser-Gittermatte (Glass fibre mesh). The reinforcement layer ends maximal 20 cm below ground level. After drying of the finish coat in contact with the ground is completed an appropriate moisture protection is installed which reaches down to the uncoated perimeter insulation panels (see detail plan 7.2.3). A damage protection to be put in front of the panels below ground has to be provided on site, e.g. a dimpled sheeting. KEIM Perimeter insulation Perimeter insulation designates all insulation below ground surface level. Perimeter insulation is installed on the outside of the respective constructive element outside of structural waterproofing (see detail plan 7.2.2). In areas with pressing water and within the capillary fringe into groundwater perimeter insulation panels must not be used. Due to the special demands under ground level the perimeter insulation panel has a general approval by the building supervisory authorities. Perimeterdämmplatten-SA or -Plus (Perimeter insulation panels) are used. KEIM Indulastic is used for glueing. Glue is applied in 6 lumps to the insulation panel. Glueing of panels is performed seamlessly from bottom to top. Under ground level reinforcement is not required. Flush-mounted plinth and facade insulation Moisture protection Glueing Reinforcement 15

17 Glueing Dowelling KEIM Plinth insulation The plinth zone begins with ground level and has a height of at least 30 cm. Due to splash water and higher mechanical loads perimeter insulation panels are used which may also minimally invade the soil level (see detail planning 7.2.1). Insulation panels crossing ground-level are bevelled-cut and covered to the substrate with the armouring layer. The insulation panels are tightly joined avoiding joints and glued using the bead-point method with KEIM Pulverkleber-90 on mineral substrates and with KEIM Indulastic on organic substrates. Insulation panels above ground level have to be dowelled if necessary. If so, the structural sealing must not be damaged up to 15 cm above ground level. KEIM Glasfaser-Gittermatte (Glass fibre mesh) is embedded in KEIM Pulverkleber-90 (Powder adhesive). To increase pressure resistance KEIM Panzergittermatte (Armoured wire mesh) can be used. KEIM finish plasters together with KEIM paint systems provide a creative design for the plinth. After drying of plaster adequate moisture protection is applied up to 5 cm above ground, e.g. KEIM Indulastic, which must continue underground until reaching the structural waterproofing. As protection against damage e.g. a corrugated plastic foil is required as next layer.
