4 1.2 Intended use This ETICS is intended for use as external insulation of buildings walls. The walls are made of masonry (bricks, blocks, stones ) or concrete (cast on site or as prefabricated panels) with and without rendering (class A1 or A2-s1,d0 according to EN :2007). The ETICS is designed to give the wall to which it is applied satisfactory thermal insulation. The ETICS shall be designed and installed in accordance with ETA holder s installation instructions and this ETA. The kit consists of components defined by the ETA holder and manufactured either by the ETA holder or his supplier(s). The ETICS is made of non load-bearing construction components. It does not contribute directly to the stability of the wall on which it is installed, but it can contribute to durability by providing enhanced protection from the effect of weathering. The minimum thermal resistance of the ETICS shall be higher than 1,0 m²k/w. The ETICS can be used on new or existing (retrofit) vertical walls. It can also be used on horizontal or inclined surfaces which are not exposed to precipitation. 2 Characteristics of products and methods of verification 2.1 General The identification tests and the assessment of the fitness for use of this ETICS according to the Essential Requirements were carried out in compliance with the ETA Guidance no. 004 concerning External Thermal Insulation Composite Systems with rendering edition March 2000 (called ETAG no. 004 in this ETA). 2.2 ETICS characteristics Reaction to fire Euroclass according to EN : F (no performance determined) Water absorption (capillarity test) Base coat Kleef- en Uitvlakkingsmortel Water absorption after 1 hour : 1 kg/m² Water absorption after 24 hours : 0,5 kg/m² The ETICS is not intended to ensure the air tightness of the building structure. Design and installation of the ETICS should take into account the principles laid down in the chapter 7 of ETAG 004 and shall be done in accordance with national instructions. The provisions made in this European Technical Approval (ETA) are based on an assumed intended working life of at least 25 years, provided that the conditions laid down in sections 4.2, 5.1, 5.2 for the packaging, transport, storage and installation as well as appropriate use, maintenance and repair are met. The indications given as to the working life cannot be interpreted as a guarantee given by the manufacturer or the Approval Body, but should only be regarded as a means for choosing the appropriate products in relation to the expected economically reasonable working life of the works. Rendering systems: Rendering system: Kleef- en Uitvlakkingsmortel + Finishing coats indicated hereafter Silicoonharssierpleister Kunstharssierpleister Silicaatsierpleister Water absorption after 24 hours < 0,5 kg/m² X X X 0,5 kg/m² Hygrothermal behaviour Hygrothermal cycles have been performed on a rig. None of the following defects occurred during the testing: blistering or peeling of any finishing, failure or cracking associated with joints between insulation product boards or profiles fitted with ETICS, detachment of the render, cracking allowing water penetration to the insulation layer. Consequently, the ETICS is assessed as resistant to hygrothermal cycles Freeze / thaw behaviour The water absorption of both the base coat and the renderings systems are less than 0,5 kg/m² after 24 hours and so the ETICS is assessed as freeze / thaw resistant.

RETICS = RD + Rrender [(m².k)/w] As described in EN ISO 6946 and EN ISO If the thermal resistance cannot be calculated, it can be measured on the complete ETICS as described in EN The thermal bridges caused by mechanical fixing devices influence the thermal transmittance of the entire wall and shall be taken into account using the following calculation: With: Uc = U + ΔU [W/(m².K)] Uc: corrected thermal transmittance of the entire wall, including thermal bridges U: thermal transmittance of the entire wall, including ETICS, without thermal bridges U = (RETICS + Rsubstrate + Rse + Rsi) -1 Rsubstrate: thermal resistance of the substrate wall [(m².k)/w] Rse: external superficial thermal resistance - [(m².k)/w] Rsi: internal superficial thermal resistance [(m².k)/w] ΔU: correction of the thermal transmittance for mechanical fixing devices (anchors, profiles) = p. n for anchors p: point thermal transmittance value of the anchor (W/K). See Technical Report n 25. If not specified in the ETA of the anchors, the following values apply: = W/K for anchors with a stainless steel screw with the head covered by plastic material and for anchors with an air gap at the head of the screw = W/K for anchors with a galvanized steel screw with the head covered by a plastic material = 0,008 W/K for all other anchors (worst case) n: number of anchors per m² The influence of thermal bridges can also be calculated as described in EN ISO It shall be calculated according to this standard if there are more than 16 anchors per m² foreseen.

See section ETA 06/0129-8/9

9 4 Assumptions under which the fitness of the product for the intended use was favourably assessed 4.1 Manufacturing The European Technical Approval is issued for the ETICS on the basis of agreed data/information, deposited with the UBAtc, which identifies the ETICS that has been assessed and judged. Changes to the ETICS or production process, which could result in the deposited data/information being incorrect, should be notified to the UBAtc before the changes are introduced. The UBAtc will decide whether or not such changes affect the ETA and consequently the validity of the CE-marking on the basis of the ETA and if so whether further assessment or alterations to the ETA shall be necessary. 4.2 Installation It is the responsibility of the ETA-holder to guarantee that the information about design and installation of this ETICS are easily accessible to the concerned people. This information can be given using reproductions of the respective parts of the European Technical Approval. Besides, all the data concerning the execution shall be clearly indicated on the packaging and/or the enclosed instruction sheets using one or several illustrations. In any case, the user shall to comply with the national regulations and particularly concerning fires and wind load resistance. Only the components described in clause 1.1 with characteristics according to clause 2 of this ETA can be used for the ETICS. The requirements given in ETAG 004, chapter 7 have to be considered. 4.3 Design To bond the ETICS, the minimal bonded surface and the method of bonding shall comply with characteristics of the ETICS (see 2.3 of this ETA) as well as the national regulations. In any case, the minimal bonded surface shall at least be 20%. To mechanically fix the ETICS, the choice and the rate of the fixings shall be determined considering: 4.4 Execution The recognition and preparation of the substrate as well as the generalities about the execution of the ETICS shall be carried out in compliance with: Chapter 7 of the ETAG 004 with, in the case of bonded ETICS, imperative removal of any existing organic finishes; National regulations in effect. The particularities in execution linked to the different methods of fixing and the application of the rendering system shall be handled in accordance with ETA-holder prescriptions. In particular it is suitable to comply with the quantities of rendering applied, the thickness regularity and the drying periods between two layers. 5 Indications to the manufacturers 5.1 Packaging, transport and storage Packaging of the components has to be such that the products are protected from moisture during transport and storage, unless other measures are foreseen by the manufacturer for this purpose. The components have to be protected against damage. It is the responsibility of the manufacturer to ensure that these provisions are easily accessible to the concerned people. 5.2 Use, maintenance and repair The finishing coat shall normally be maintained in order to fully preserve the ETICS s performances. Maintenance includes at least: visual inspection of the ETICS the repairing of localised damaged areas due to accidents; the aspect maintenance with products adapted and compatible with the ETICS (possibly after washing and ad hoc reparation). Necessary repairs should be performed as soon as the need has been identified. The design wind load suction and the national regulations (taking into account the national safety factors, the design rules, ); The characteristic resistance of the anchors into the considered substrate (see installation parameters effective anchorage depth, characteristic resistance... in the ETA of the anchor; The safety in use of the ETICS (cf. 2.3), according to the method of fixing.
