1 Using of ETIC System II Verarbeitung WDV-System II ETICS hard foam insulation boards with mechanical fixation (rail system) System properties Certified external thermal insulation composite system with facade insulation boards of expanded polystyrene hard foam with a circumferential groove for jointless mechanical fixation the insulation boards to the substrate using the ETICS horizontal and vertical connection profiles including anchors. The mechanical fixation bridges nonload-bearing surface layers, and can compensate up to 3 cm of substrate unevenness. This generally eliminates the need for labor-intensive substrate preparation, such as the removal of insufficiently load-bearing paint and render layers. In this manner, the costs for extensive substrate preparation as well as the transport and disposal costs for building waste and other materials are saved. Date: Using of ETIC System II Page 1 of 12

2 Rated thermal conductivity λ: or W/(m K) in accordance with DIN V , depending on the type of insulation board Reaction to fire: schwer entflammbar (flame retardant) B1: (up to 200 mm, > 100 mm with fire protection measures) or normal entflammbar (flammable) B2: (> 100 mm to 200 mm without fire protection measures) Insulation board format: 50 x 50 cm Insulation material thickness: Up to 200 mm Insulation board type: W/(w K): ETICS Hard Foam Insulation Board 3808, with circumferential groove. Field of application For thermal insulation of existing and new buildings on stable, even, dry and load-bearing substrates, e.g. on brickwork and concrete with or without render up to a building height for which the use of schwer entflammbar (flame retardant) building materials is permitted, generally up to the high-rise building-limit. As an economical ETIC system, specifically for facade insulation on buildings with substrates that are not strong enough to support the bonding technique, e.g. on substrates with non-load-bearing coatings. Data Sheet 5v02 In accordance with National Technical Approval for insulation material thicknesses up to 200 mm. Its application in areas exposed to splash water (height of approx. 30 cm) requires special measures (see Area exposed to splash water for more information). System application Structural requirements Before implementation of the ETICS work, ensure that the substrate no longer has a high moisture content. If subsequent interior work with plaster or screed mortars is performed, ensure adequate ventilation. See also BFS Leaflet No. 21, Item 3.4 Building Moisture. Windows and exterior doors, covers, gutters, window sills, roller shutter boxes and shutter guide rails must have already been installed. The layer thickness of the entire insulation must be taken into account when planning window sills, covers, window frames, roof overhangs, etc. For insulation on old buildings, the existing connections and details such as window sills, rain pipes, exterior lighting, railings, door bells, ventilation grates, etc. must be completed correspondingly earlier. Substrate preparation The substrate must be stable, solid, dry and capable of supporting the mechanical fastening. Fungi, algae and plant cover must be removed. Any additional substrate treatment, such as high-pressure cleaning of the facade surface, depends on the respective substrate conditions. Chip off any coarse, protruding sections of mortar or concrete. A substrate unevenness of up to 3 cm can be leveled out with ETICS Spacers Coarser substrate unevennesses must be compensated with render in accordance with DIN V18550, mortar group PII. The compatibility of any existing coatings with the adhesive mortar must be assessed by an expert. Using of ETIC System II Page 2 of 12

3 Lower system ending Classic mounting of the ETICS Starter Profile (Figure 1) Use ETICS Impact Screws 3546 as well as ETICS Starter Profile Connectors 3776 and ETICS Starter Corner Profiles 3777 to affix the ETICS Starter Profile 3770 in accordance with the insulation board thickness such that it is flush. Limited unevennesses of the substrate can be compensated with ETICS Spacers Ending with ETICS Starter Profile As an alternative variant of a recessed base connection without thermal bridges, the Qju Fixing Brackets can be used with the ETICS Base Joint Profile. More information on this variant can be found in the Data Sheet ETICS Base Joint Profile Adhesive application (Figure 2) In accordance with the national technical approval, one lump of the adhesive ETICS Powder Adhesive 3550, ETICS Powder Adhesive VZ 3600 or ETICS Adhesive and Reinforcement Mortar L 3500 must be applied to the back of the ETICS hard foam insulation boards. The size of the adhesive lump must be approximately 20% of the insulation board surface. Adhesive consumption approximately 2.0 kg/m², depending on the distance to the substrate. Insulation board mounting (Figure 3) Affix the ETICS hard foam insulation boards such that the back with its surrounding cutout is toward the wall, to the prepared substrate, from bottom to top, in a running bond pattern with a precise fit such that they are flush, even and offset-free using ETICS Horizontal Connection Profiles 3543 and ETICS Vertical Connection Profiles 3544 Consumption ETICS Horizontal Connection Profiles 3543: 2.0 m/m² ETICS Vertical Connection Profiles 3544: 4.0 pcs./m². The ETICS Horizontal Connection Profiles 3543 must be affixed with approved ETICS anchors that have a maximum spacing of 30 cm. There are different, approved ETICS anchors available for this purpose; they are to be selected such that they are appropriate for the substrate. More information on anchor selection can be found in the Data Sheet 5d02 Anchoring ETIC System II. Substrate unevennesses of up to 3 cm can be compensated with ETICS Spacers Slide the insulation board groove onto the projecting section of the starter profile or into the horizontal connection profiles, and insert the vertical connection profiles into the vertical groove. Then press the insulation board evenly onto the substrate and align it. To ensure a wind-tight seal and good stabilization, all joints at system endings, such as in the area of the starter profile, on the building corners and in the area of facade openings, must be sealed with an uninterrupted line of adhesive on the back of the board. Connections to components such as windows or doors must also be created by bonding the insulation boards (edge-beading lump method), including fixation with ETICS anchors. The substrate must be appropriately pretreated in these areas to be ready for bonding. For insulation board cut-outs, recreate the required groove and cutout using the Hard Foam Groove Plane When mounting the insulation boards, ensure tightly abutting joint areas. Unavoidable joints and gaps (> 2 mm) must be sealed sufficiently with a similar type of insulation material such that no reinforcement plaster can penetrate. For example, gaps up to max. 5 mm can be filled with PUR Filler Foam Due to the permissible dimensional tolerances of the insulation boards, increased gaps must be expected with increasing insulation layer thickness. These must be sealed as described. No adhesive mortar may penetrate into the insulation board joints. Using of ETIC System II Page 3 of 12

4 Dovetailing of the insulation boards (offset joints) must be implemented at all external building corners. Alternatively, the insulation boards can also be mounted without corner dovetailing. In this case, the insulation boards must be full-surface bonded together in the overlapping area (continuous vertical joint) over the entire thickness with Qju Adhesive Foam 3700 or PUR Filler Foam At facade openings, e.g. windows and doors, do not continue the vertical insulation board joints across the opening s corner, if possible; instead, mount the insulation boards in an overlapping manner (notched out). Horizontal joints are permissible as long as proper diagonal and interior corner reinforcement is ensured. Cross joints must be avoided. Any projections which may arise must be sanded off after drying. Completely remove all sanding dust. Anchoring (Figure 4) After the adhesive has dried sufficiently (at least 3 days), additional anchoring of the ETICS hard foam insulation boards is to be performed appropriately for the substrate and building height. A variety of approved ETICS disk anchors are available and must be chosen to be appropriate for the substrate. Detailed information on system anchoring, anchor selection and anchor arrangement adapted to ETIC System II for the mounting and additional board anchoring is clearly presented in the Data Sheet 5d02 Anchoring ETIC System II. Reinforcement (Figure 4) Corner reinforcement On all corners and edges, e.g. external building corners, window and door reveals, plumb and flush corner reinforcement must be implemented before the surface reinforcement. For this purpose, use ETICS Mesh Corner Protection Profile 3763, ETICS Vario Mesh Corner Protection 3507, ETICS Aluminum Corner Protection Profile 3787 or ETICS Mesh Corner, special Diagonal / Interior corner reinforcement Additional diagonal and interior corner reinforcement must be implemented in all corner areas of facade openings, e.g. windows, doors and niches. We recommend using the ETICS Diagonal Reinforcement Arrow 3713 or the ETICS Diagonal Reinforcement Angle 3692 for this purpose. Surface reinforcement For reinforcement, apply the reinforcement plaster to completely cover the entire surface of the bonded hard foam insulation boards. Lay ETICS Reinforcement Fiber Mesh 3797 (free of bubbles and folds) into the wet reinforcement layer such that the individual mesh sheets overlap by approx. 10 cm, then cover it wet-on-damp with another layer of reinforcement plaster. Detailed information on reinforcement implementation can be found in the Data Sheet ETICS Reinforcement Fiber Mesh 3797 and in the data sheets for the reinforcement plasters. The following reinforcement plasters can be used: ETICS Reinforcement Plaster ZF-SiL 3585 ETICS Reinforcement Plaster ZF-R 3636 ETICS Powder Adhesive 3550 ETICS Powder Adhesive VZ 3600 ETICS Adhesive and Reinforcement Mortar L 3500 For a thick reinforcement layer (6 7 mm), use ETICS Adhesive and Reinforcement Mortar L 3500 in combination with ETICS Mesh Corner Profile DS 3686, ETICS Window Joint Profile 3707, and ETICS Click-On Profile During implementation, follow the additional instructions in the data sheets of the products mentioned above. Top coats (Figure 5) After sufficient drying of the reinforcement layer (at least 3 days), the top coat is applied in a coating build-up, using one of the following: Rausan KR/R (organically bonded render) Silicone Render KR/R Silcosil KR/R (siliconereinforced render) Silicate Render KR/R Mineral Lightweight Render KR/R/G Flat facing bricks Depending on the combination or reinforcement plaster and top coat, an intermediate coat may be necessary.

5 For colored coating of ETIC systems, a lightness reference value (LRV) of 20 must be observed unless additional measures are taken. Color shades with an LRV < 20 can be realized with the Brillux SolReflex system. Please consult the SolReflex Colors of Any Darkness Level on ETICS Brochure and the Data Sheet 5tsr. Reinforcement layers extending into the soil must be protected with ETICS Multiflex Follow the instructions in Data Sheet Connections and joints System connections to e.g. windows and doors must be properly implemented with connection profiles or sealing tape depending on the individual requirements. Use ETICS Window Joint Profile, special+ 3748, an ETICS Window Joint Profile 3707 or PF 3820 or ETICS Sealing Tape 3796 for this purpose. For windows flush with the facade or positioned in front of it, the Brillux Consulting Service should always be contacted with regard to the exact creation of the connections, especially in the region of the window sills. For connection to roof soffits, use ETICS Sealing Tape 3796 and, depending on the roof structure, also use ETICS Roof Ventilation Profile Required expansion joints must be created with ETICS Expansion Joint Profile G 3805 or ETICS Starter Profile 3770 in combination with ETICS Sealing Tape Mounting of third party components Brillux offers a large number of mounting anchors for the subsequent attachment of third party components such as railings, exterior lights, shutter guide rails, signs, advertisements, canopies, shades, awnings, shutters, etc. while avoiding thermal bridges as well as compressive and tensile stresses. These must be properly mounted before or during the bonding of the insulation boards. A selection guide and detailed information on mounting anchoring as well as proper application can be found in the Mounting Anchoring Chapter in the Internet at and in the individual data sheets. Area exposed to splash water Use ETIC system VI for insulation in areas exposed to splash water (up to approx. 30 cm above the ground surface). With the special ETICS Base and Perimeter Insulation Boards, this system is particularly suited for this application as well as for insulation that extends into the ground. For more information on how to apply the system, refer to Using of ETIC System VI Data Sheet 5d06. Data Sheet 5v02 Fire protection information The reaction of ETIC systems to fire is influenced by the system components, such as insulation material type and thickness, reinforcement plaster, and top coat, as well as by the structural design of openings, components and detail connections. In the planning and implementation of ETIC systems with ETICS hard foam insulation boards, e.g. the following aspects must be taken into consideration in order to maintain a reaction to fire of class B1, schwer entflammbar (flame retardant), in accordance with DIN 4102: For insulation material thickness > 10 cm: Lintel design on building openings with ETICS mineral wool lamella strips; Alternatively, it is also possible to create a surrounding fire barrier Integration of window frames located in front of the facade Creation of expansion joints Additional installation of ETIC systems (for a total insulation material thickness > 10 cm) Integration and over-insulation of roller shutter boxes and blinds In general: Bridging of fire walls Protective coating in the splash water area The entire topic of fire protection, including implementation descriptions and diagrams, is described in detail in the Technical Data Sheet 5b04 ETICS Fire Protection.
