2. ETA 19/0482 of 28/02/2022 — page 2 of 12 Translations of this European Technical Assessment in other languages shall fully correspond to the original issued document and should be identified as such. Communication of this European Technical Assessment, including transmission by electronic means, shall be in full. However, partial reproduction may be made, with the written consent of the issuing Technical Assessment Body. Any partial reproduction has to be identified as such. This European Technical Assessment may be withdrawn by the issuing Technical Assessment Body, in particular pursuant to information by the Commission according to Article 25, Paragraph 3, of Regulation (EU) No. 305/2011. 1. Technical description of the product The External Thermal Insulation Composite System (from now on, referred to as ETICS) ISOVIT CLÁSSICO is designed and installed in accordance with the ETA manufacturer’s design and installation instructions, deposited with LNEC 1 . ISOVIT CLÁSSICO is a bonded system with supplementary mechanical fixings used primarily to provide stability until the adhesive has dried and increase the adherence of the system reducing the risk of detachment. TThe ETICS comprises the components identified in Table 1, which are factory produced by the manufacturer or by a supplier. It is made up on site from these components. The manufacturer is ultimately responsible for the ETICS. 2. Specification of the intended use in accordance with the applicable European Assessment Document (EAD) This ETICS is intended to be used as external thermal insulation for building walls. The walls are made of masonry (bricks or blocks) or concrete (cast on site or as prefabricated panels) with a reaction to fire classification A1 to A2-s2,d0 according to EN 13501-1 or A1 according to the EC decision 96/603/EC as amended. The ETICS is designed to give the wall to which is applied satisfactory thermal insulation. The ETICS is made of non load-bearing construction elements. It does not contribute directly to the stability of the wall on which is installed, but it can contribute to its durability by providing enhanced protection from the effect of weathering. The thermal resistance of the ETICS shall be ≥ 1.0 m 2 K/W. This 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. The ETICS is not intended to ensure the air tightness of the building structure. Design and installation of ETICS should take into account the principles laid down in EAD 040083-00-0404 (see 1.1) and shall be done in accordance with national instructions. This ETA covers the application of bonded ETICS where the concrete for testing of bond strength is representative for masonry or concrete. For bonded applications onto other substrates (e.g. organic paints or ceramic tiles), testing on the job site is necessary. The provisions made in this ETA are based on an assumed working life of at least 25 years, provided that the conditions laid down for the installation, appropriate use, maintenance and repair are met. The indications given on the working life cannot be interpreted as a guarantee given by the producer, but are to be regarded only as a means for choosing the right product in relation to the expected economically reasonable working life of the works. Installation The ETICS is installed on site. It is the responsibility of the manufacturer to guarantee that the information about design and installation of this ETICS is effectively communicated to the concerned people. This information can be given using reproductions of the respective parts of this European Technical Assessment. 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. The wall on which the ETICS is applied shall be sufficiently stable and airtight. Its stiffness shall be big enough to ensure that the ETICS is not subjected to deformations, which could lead to damage. The requirements given in EAD 040083-00-0404 (see 1.3.1) have to be considered. Design The user shall comply with the national regulations particularly concerning fire and wind load resistance. Only the components described in clause 1 with characteristics according to clause 3 of this ETA can be used for this ETICS. The works including the details (such as connections and joints) shall be designed in order to avoid water penetration behind the system. To bond the ETICS, the minimum surface area and the method of bonding shall comply with the characteristics of the ETICS (see 3.2.4 of this ETA) as well as the national regulations. In any case, the minimum bonded surface shall be at least 20%. 1 The technical documentation of this European Technical Assessment is deposited with Laboratório Nacional de Engenharia Civil (LNEC) and, as far as relevant for the tasks of the notified body (bodies) involved in the assessment and verification of constancy of performance procedure, is handed over to the notified body (bodies).

TABLE 4 Equivalent air thickness System specimens Equivalent air thickness (m) Base coat + standard mesh + key coat + finishing coat 0.7 f) Dangerous substances This system complies with the provisions of Guidance Paper H 2 . A declaration of conformity was made by the manufacturer stating that all ETICS components verify the established legal limits for products with some degree of toxicity. In addition to the specific clauses relating to dangerous substances contained in this ETA, there may be other requirements applicable to the ETICS falling within its scope (e.g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of Regulation (EU) No. 305/11, these requirements need also to be complied with, when and where apply. 3.2.4 Safety on use (BWR 4) a) Bond strength – Base coat onto EPS board (EAD 040083-00-0404 – clause 2.2.11.1) Tests were performed on the system applied on the rig, after hygrothermal cycles. The results are summarized in Table 5. In all cases, bond strength values are higher than 80 kPa, so complying with the requirements of EAD 040083-00-0404.

6. ETA 19/0482 of 28/02/2022 — page 6 of 12 – Adhesive onto concrete (EAD 040083-00-0404 – clause 2.2.11.2) Tests were performed on samples of EPS insulation boards faced with adhesive. The results are summarized in Table 6. In all cases, the results are within the limits defined by EAD 040083-00-0404. TABLE 7 Bond strength between adhesive and substrate (concrete) Specimen Bond strength (kPa / Failure pattern) 1 Initial state After conditioning 48 h immersion in water + 2 h 23 °C/ 50% RH 48 h immersion in water + 7 days 23 °C/ 50% RH Adhesive + substrate (concrete) Min.: 660 Average: 750 / FP:B Min.: 330 Average: 400 / FP:A/B Min.: 1160 Average: 1680 / FP:B 1 Failure pattern: FP: A – adhesion failure (failure between adhesive and substrate) and FP: B – cohesion failure (failure in the adhesive) and FP:C – cohesion failure (failure in the substrate). The minimal bonded surface S is calculated as follows, with a minimum of 20%: S (%) = [30 × 100] / B where: B minimum mean failure resistance of the adhesive to the insulation product in dry conditions expressed in kPa (150 kPa); 30 kPa corresponds to the minimum requirement. The calculated minimum bonded surface S value is 20%, therefore the minimum bonded surface to adopt is 20%. b) Wind load resistance (EAD 040083-00-0404 – clause 2.2.13) Performance not assessed. 3.2.5 Protection against noise (BWR 5) Performance not assessed (EAD 040083-00-0404 – clause 2.2.22.1). 3.2.6 Energy economy and heat retention (BWR 6) a) Thermal resistance (EAD 040083-00-0404 – clause 2.2.23) The additional thermal resistance R ETICS provided by the ETICS to the substrate wall is calculated in accordance with EN ISO 6946 from the nominal value of the insulation product ́s thermal resistance R D given accompanied to the CE marking and from the thermal resistance of the rendering system R render which is about 0.02 m 2 .K/W: R ETICS = R D + R render Thermal bridges caused by mechanical fixing devices influence the thermal transmittance of the entire wall and shall be taken into account. The corrected thermal transmittance of the entire wall including ETICS and thermal bridges is calculated using the following expression: U c = U + χ p .n where: U c corrected thermal transmittance of the entire wall including ETICS and thermal bridges (W/(m².K)); U thermal transmittance of the entire wall including ETICS without thermal bridges (W/(m².K)); n number of anchors (through insulation product) per m²; χ p point thermal transmittance value of an anchor (W/K). See EOTA Technical Report TR 025. If not specified in the anchor’s ETA, the following values apply: = 0.002 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 ( χ p .n negligible for n < 20); = negligible for anchors with plastic nails (reinforced or not with glass fibres). The term χ p .n has only to be taken into account if it is greater than 0.04 W/(m².K). The thermal transmittance of the entire wall including ETICS without thermal bridges is determined as follows: U = 1 / (R i + R render + R substrate + R se + R si )

4. ETA 19/0482 of 28/02/2022 — page 4 of 12 The ETICS meets the requirements of class B-s1,d0 according to EN 13501-1+A1. 3.2.3 Hygiene, health and environment (BWR 3) a) Water absorption (EAD 040083-00-0404 – clause 2.2.5.1) The results of the water absorption test of the base coat (system with and without finishing), presented in Table 2, verify the following condition: • water absorption after 1 hour < 1 kg/m 2 The system is therefore judged to have satisfactory performance concerning water absorption, independently of the finishing coat. TABLE 2 Water absorption (capillarity test) System specimens Water absorption after 1 h (kg/m 2 ) Water absorption after 24 h (kg/m 2 ) EPS + base coat + standard mesh Min.: 0.02 Average: 0.03 Min.: 0.22 Average: 0.23 EPS + base coat + standard mesh + key coat + finishing coat Min.: 0.03 Average: 0.04 Min.: 0.20 Average: 0.21 b) Hygrothermal behaviour (EAD 040083-00-0404 – clause 2.2.6) The ETICS has been assessed on a rig including the thermal insulation and all rendering system. During heat-rain and heat-cold cycles, none of the following defects occurs during testing: • blistering or peeling of the finishing coat, base coat or rendering system; • failure or cracking associated with joints between insulation product boards or profiles fitted with the system; • detachment of finishing coat, base coat or rendering system; • cracking allowing water penetration to the insulation layer. The ETICS is therefore assessed as resistant to hygrothermal cycles. c) Freeze / thaw behaviour (EAD 040083-00-0404 – clause 2.2.7) The results of the water absorption test of the base coat (system with and without finishing), presented in Table 2, verify the following condition: • Water absorption after 24 hour < 0.5 kg/m 2 The system is therefore judged as freeze-thaw resistant without further testing. d) Impact resistance (EAD 040083-00-0404 – clause 2.2.8) The resistance to hard body impact (3 and 10 Joules) tests carried out on samples of systems compositions lead to the use categories presented in Table 3. TABLE 3 Impact resistance to hard body impacts System Impact Impact diameter (mm) Presence of cracks Use categorie 1 EPS + base coat + standard mesh + reinforced mesh 3 J Average: 19 no cracking II 10 J Average: 37 cracking and no penetration EPS + base coat + standard mesh + key coat + finishing coat 3 J Average: 15 no cracking II 10 J Average: 61 cracking and no penetration EPS + base coat + standard mesh + reinforced mesh + key coat + finishing coat 3 J Average: 19 no cracking I 10 J Average: 28 no cracking 1 Use categories: Category I – zones readily accessible at ground level to the public and vulnerable to hard body impacts but not subjected to abnormally rough use. Category II – zones liable to impacts from thrown or kicked objects, but in public locations where the height of the system will limit the size of the impact; or at lower levels where access to the building is primarily to those with some incentive to exercise care.
