This European Technical Approval is not to be transferred to manufacturers or agents of manufacturers other than those indicated on page 1, or manufacturing plants other than those laid down in the context of this European Technical Approval. 4. This European Technical Approval may be withdrawn by LNEC, in particular pursuant to information by the Commission according to Article 5(1) of Council Directive 89/106/EEC. 5. Reproduction of this European Technical Approval including transmission by electronic means shall be in full. However, partial reproduction can be made with the written consent of LNEC. In this case partial reproduction has to be designated as such. Texts and drawings of advertising brochures shall not contradict or misuse the European Technical Approval. 6. Subject to the application introduced, the European Technical Approval is issued by the approval body in its official language. This version corresponds fully to the English version circulated in EOTA. Translations into other languages have to be designated as such. II. Specific conditions of the European Technical Approval (ETA) 1. Definition of the product and intended use 1.1 Definition of the product This European Technical Approval applies to the factory made thermal and acoustic insulation product Cortipan of granulated natural cork agglomerated with an additional binder based on polyurethane resin (PU), in the form of boards and without facings, hereafter referred to as insulation boards. The insulation boards are not made of used or recycled cork (other than recirculated from the product boards) and do not include additives (e.g. flame/fire retardants, biocides, BaP-bituminous based binders). The boards are produced by a continuous moulding (pressing) process. After moulding and curing of the boards one of the faces (upper face) is mechanically ground to rectify its surface. Standard dimensions of the insulation boards are 1000 mm 500 mm and their thickness is between 20 mm and 60 mm. The nominal density range is 170 kg/m 3 (+/ 15 %). The nominal length, width, thickness and densities, and the corresponding tolerances are given in Table 1. 1 Official Journal of the European Communities, L 40, , p Official Journal of the European Communities, L 220, , p Official Journal of the European Union, L 284, , p Diário da República, Series I-A, no. 84, , p Diário da República, Series I, no. 5, , p Official Journal of the European Communities, L 17, , p

Airborne sound insulation boards to be used in walls, roofs and ceilings (inside cavities or as lining for internal walls) and in floors (inside cavities or in non-living areas of attic floors). The insulation boards cannot be installed as an impact sound insulation product and cannot be exposed to compression loads. The insulation boards shall not be used in places where they may be exposed to wetting, weathering or moisture. The insulation boards are not self-supporting elements; thus they require an additional supporting element (wall, roof, or ceiling or floor). The boards are attached to the substrate either by means of cement-based adhesive or mechanically fixed with additional permanent elements. In ceiling and floor applications the boards may be simply laid over the substrate (without adhesive bond or mechanical fixings). Regarding ER 3 the following use categories have to be considered, depending on the intended use of the product: Category IA1: Product with direct contact to indoor air Category IA2: Product with no direct contact to (e.g. covered products) but possible impact on indoor air Category IA3: Product with no contact to and no impact on indoor air The provisions made in this European Technical Approval are based on an assumed working life of the insulation board for the intended use of 50 years, provided that the conditions laid down in sections 4.2, 5.1 and 5.2 for the packaging, transport, storage, installation and use 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 products in relation to the expected economically reasonable working life of the work. 2. Characteristics of the product and methods of verification 2.1 Composition and production method With regard to composition and production method the insulation board must correspond to that which was the basis for the approval tests. Composition and production methods are deposited with LNEC.

The control plan is laid down in the context of the factory production control operated by the manufacturer and is deposited within LNEC 10. The results of the factory production control shall be recorded and evaluated in accordance with the provisions of the control plan Other tasks for the manufacturer The manufacturer shall make a declaration of conformity, stating that the boards are in conformity with the provisions of this ETA Tasks for the approved body Initial type-testing of the boards The tests and verifications on which this ETA is based have been carried out on samples of the current production. For the purpose of initial type-testing, the results of these tests shall be used unless there are changes in the production line or plant. In such cases, the necessary new initial type-testing has to be selected by LNEC. These tests could be taken over by the ETA holder for declaration of conformity. 3.3 CE marking The CE marking shall be affixed on the packaging or on the accompanying documents, e.g. the EC declaration of conformity. The letters CE shall be accompanied by the following additional information: The name and address of the producer (legal entity responsible for the manufacture), The last two digits of the year in which the CE marking was affixed, The number of the European Technical Approval, Reaction to fire (Euroclass), Density, Nominal thickness, Nominal length and nominal width, Declared value of thermal conductivity λ D, Declared value of airflow resistivity. 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 insulation boards on the basis of agreed data/information, deposited within LNEC, which identifies the board that has been assessed and judged. Changes to the boards or production process, which could result in this deposited data/information being incorrect, should be notified to LNEC before the changes are introduced. LNEC will decide whether or not such changes affect the approval and consequently the validity of the CE marking on the basis of the approval and if so whether further assessment or alterations to the approval shall be necessary. 4.2 Installation of the product in the works The insulation boards shall only be installed in structures where they are protected from rain, weathering and moisture. The installation instructions given by the manufacturer shall be taken into account for installation of the insulation boards. Where the insulation boards are fixed by using adhesives and/or anchors, only such adhesives or anchors shall be used, which are suitable for this purpose. The assessment of these fixing means is not part of this European Technical Approval. The insulation boards shall be protected from moisture during the installation. The insulation boards shall not be exposed to compression loads. The conditions in clause 1.2 shall be taken into account. 5. Indications to the manufacturers 5.1 Packaging, transport and storage Packaging of the product shall be carried out so that the insulation board is protected from moisture during transport and storage, unless other measures are foreseen by the manufacturer for this purpose. 10 The Control Plan is a confidential part of the European Technical Approval and only handed over to the approved body or bodies involved in the procedure of attestation of conformity.
