Technical details necessary for the implementation of the AVCP system, as provided for in the applicable EAD The manufacturer shall exercise permanent internal control of production of concerned product. All the elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures, including records of results performed. This production co ntrol system shall ensure that the product is in conformity with this ETA. The manufacturer may only use components stated in the technical documentation of this ETA including Control Plan. The incoming raw materials are subjected to verifications by the m anufacturer before acceptance. For the components of the ETICS which the manufacturer does not manufacture by himself, he shall make sure that factory production control carried out by the other manufacturers gives the guarantee of the components complian ce with the ETA. The factory production control shall be in accordance with the Control Plan which is a part of technical documentation of this European Technical Assessment . The control plan has been agreed between the manufacturer and Itecons and is laid down in context of the factory production control system operated by the manu facturer and deposited within Itecons . The results of factory production control shall be recorded and evaluated in accordance wi th the provisions of the control plan. 5.1 Other tasks for the manufacturer The manufacturer shall, on the basis of a contract, involve a body which is notified for the tasks referred to in section 4 in the field of ETICS in order to undertake the actions laid down in this clause. For this purpose, the control plan shall be handed over by the manufacturer to the notified bodies involved. For initial type - testing of the ETICS and the components the results of the tests performed as part of the assessment fo r the ETA shall be used unless there are changes in the production line or plant. In such cases the necessary testing has to be agreed with I tecons . The manufacturer shall make a declaration of performance, stating that the ETICS is in conformity with the provisions of this ETA. Changes to the ETICS or the components or their production process should be notified to Itecons before the changes are introduced. I tecons will decide whether or not such changes affect the ETA and if so whether further assessment or alterations to the ETA shall be necessary. 5.2 Tasks for the Notified Body (bodies) 5.2.1 Initial inspection of factory and of factory production control The Notified Body shall ascertain that, in accordance with the Control Plan, the factory (in particular the employees and the equipment) and the factory production control are suitable to ensure continuous and orderly manufacturing of the components according to the specifications mentioned in this ETA.

5. ETA 19/0062 – version 1 of 02 /08 /20 19 – page 5 of 15 ETICS are not intended to ensure the air tightness of the timber frame building structure. The timber frame building wall as such has therefore to be air tight to: a) Reduce the thermal transmittance of the wall b) Avoid interstitial condensation due to convection. The provisions made in this European Technical Assessment are based on an assumed working life of the ETICS of at least 25 years, provided that the requirements for the packaging, transport, storage, installation as well as appropriate use, maintenance and repair are met. The indication given on the working life cannot be interpreted as a guarantee given by the manufacturer or the Technical Assess ment 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. 3. Performance of the product and references to the methods used for its assessment 3.1 Mechanical resistance and stability (BWR 1) Not relevant. 3.2 Safety in case of fire (BWR 2) 3. 2.1 Reaction to fire of the ETICS T he reaction to fire was tested according to ISO 11925 - 2:2010, ISO 11925 - 2:2010/Cor1:2011 and EN 13823:2010+A1:2014 and classified according to EN 13501 - 1:2007+A1:2009. The ISOVIT Cork Wood system meets the requirements of B - s1, d0 . Note: A European reference fire scenario has not been laid down for facades. In some Member States, the classification o f ETICS according to EN 13501 - 1:2007+A1:2009 might not be sufficient for the use in facades. An additional assessment of ETICS according to national provisions (e.g. on the basis of large scale test) might be necessary to comply with Member State regulatio ns, until the existing European classification system has been completed. 3. 3 Hygiene, health and the environment of ETICS and its components (BWR 3) 3. 3 .1 Water absorption of the ETICS (capillarity test) The results of the water absorption test , performed according to section 2.2.2.1 of EAD 040089 - 00 - 0404, regarding the base coat (system without finishing) and of the rendering (system with finishing) , are presented in Table 2, verify the following condition: • Water absorption after 1 hour <1 kg/ m 2 • Water absorption after 24 hours <0.5 kg/m 2 The system is therefore judged to have satisfactory performance concerning water absorption.

Specification of the intended use(s) in accordance with the applicable European Assessment Document (hereinafter EAD) The ETICS are designed to give the timber frame building wall to which they are applied additional ther mal insulation and protection f r o m effects of weathering . The ETICS can be used on new or existing (retrofit) vertical timber frame building walls. They can also be used on horizontal or inclined surfaces which are not exposed to precipitation. The surface for the application of ETICS can be a board substrate ( wood based panels, solid wood panels, plasterboards, gypsum bonded boards, cement bonded boards, etc. ). The board substrate must be suitable for humid conditions as specified in EN 13986. ETICS are non - load - bearing construction elements. They do not contri bute directly to the stability of the timber frame building wall on which they are installed. The verification of the structural capacities of the wall and their suitability for the application of ETICS shall be in accordance with ETAG 007 (and its convers ion into EAD), clause 5.1 using calculation methods (EN 1995 - 1 - 1, Eurocode 5 Part 1 - 1, etc.) as well as verifications by testing (EN 380, EN 594, EN 595, EN 596, etc.) where the load bearing capacity is unable to calculate. The ETICS can contribute to the durability of a timber frame building by providing enhanced protection from the effects of weathering.

3. ETA 19/0062 – version 1 of 02 /08 /20 19 – page 3 of 15 Specific parts 1. Technical description of the product This product is an ETICS (External Thermal Insulation Composite System) with rendering for the use on timber frame buildings – a kit comprising components which are factory - produced by manufacturer or component suppliers. The ETICS manufacturer is ultimately re sponsible for all components of ETICS specified in this ETA. The ETICS kit comprises a prefabricated insulation product of Expanded Insulation Corkboard ( ICB ) to be bonded with supplementary mechanical fixings onto a wall. The methods of fixing and the rel evant components of the ETICS are specified in Table 1. The insulation product is faced with a rendering system consisting of one or two layers (site applied), one of which contains reinforcement . The rendering is applied directly to the insulation panels, without any air gap or disconnecting layer. The ETICS may include special fittings (e.g. base profiles, corner profiles ...) to treat details of ETICS (connections, apertures, corners, parapets, sills ...). The assessment and performance of these components i s not addressed in this ETA, however the ETICS manufacturer is responsible for adequate compatibility and performance within the ETICS when the components are delivered as a part of the kit.
