The cellulose fibres are produced from waste paper by mechanical crushing. During the manufacturing process the product is provided with fire retardants. 1.2 Intended use The insulation material can be used for the following intended uses: - Thermal insulation material, to be used in cavities of e.g. external or internal roofs, ceilings, walls and floors, between rafters and timber work, supplied as loose fill by means of manual or mechanical installation. The insulation material shall only be installed in structures where it is protected from wetting, weathering and direct contact to soil. The provisions made in this European Technical Approval are based on an assumed working life of the insulating material of 50 years, provided that the conditions laid down in clauses 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 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. 2 Characteristics of product and methods of verification 2.1 Characteristics of product The In-situ formed loose fill thermal insulation material made of cellulose fibres with trade name Papiruld and sub trade name Envinsu shall correspond to the respective values laid down in the technical documentation 5 of this European technical approval. 5 The technical documentation of this European approval is deposited with SITAC and, as far as relevant for the task of the approved bodies involved in the attestation of conformity procedures, is handed over.

10 Page 10 (10) of European Technical Approval ETA-13/0623 issued on Parameters for design of construction works Design value of thickness, density and thermal conductivity The design value of thermal conductivity shall be laid down according to relevant national provisions. The nominal thickness for calculating the thermal resistance is to be determined from the installation thickness taking account the settlement given in table 1 and 2 of this European Technical Approval. The nominal thickness is equal to the clear span of the filled cavity. The insulation layer shall have a constant installation thickness taking into account the nominal thickness. For that purpose suitable height marks shall be arranged in sufficient distances before the processing where applicable. The executing company shall check the installation thickness. Depending on the area of application the density at built-in stage stated in Table 1 and 2 of this European Technical Approval shall be considered. The execution company shall verify the density Executing companies The insulation material may only be machine processed by companies stated in a list of the manufacturer which have adequate experience in installing the material. Concerning this matter the manufacturer has to train these companies. 5 Indications to the manufacturer 5.1 Packaging, transport and storage Packaging of the product shall be performed such that the product is protected from moisture during transport, storage and installation, unless other measures are foreseen by the manufacturer for this purpose. The quantity in the packages and the required density after installation shall be stated in the information accompanying the CE-marking. 5.2 Use, maintenance, repair The product is only to be used in places where it will not be exposed to wetting or weathering. In the information accompanying the CE marking the manufacturer shall specify that the product shall be installed following the installation instruction given by the manufacturer.
