Foreword
This document (prEN 15101-2:2004) has been prepared by Technical Committee CEN/TC 88 “Thermal
insulating materials and products”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports the essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document
This European Standard is one of a series for mineral wool, expanded clay, expanded perlite, exfoliated
vermiculite, polyurethane/polyisocyanurate, cellulose and urea formaldehyde in-situ formed insulation products
used in buildings, but this standard may be used in other areas where appropriate.
prEN 15101-2:2004 (E)
1 Scope
This document specifies requirements for in-situ formed loose-fill cellulose thermal insulation (LFCI) products
when installed in internal walls, external walls, floors, galleries, roofs and ceilings.
This document is a specification for the installed products.
This document describes, when taken together with Part 1, the product characteristics that are linked to the
essential requirements of the EU Construction Products Directive. This document also specifies the checks and
tests to be used for the declarations made by the installer of the product and the rules for the evaluation of
conformity.
This document does not specify the required level of all properties to be achieved by a product to demonstrate
fitness for purpose in a particular application. The required levels are to be found in regulations or non-conflicting
standards.
Products with a declared thermal conductivity at 10 °C (mean temperature) greater than 0,060 W/(m.K) or a
declared thermal resistance lower than 0,25 m · K/W are not covered by this document.
This document does not cover factory made cellulose products intended to be used for the insulation of
buildings or in-situ cellulose products for the insulation of building equipment and industrial installations.
This document does not specific performance requirements for load-bearing applications.

4 Requirements
4.1 General
The installer shall use an insulation product that complies with Part 1 of this document.
The installer shall inspect the building in accordance with manufacturers guidelines and National Rules, in
order to determine whether it is suitable for application of the product in accordance with the information given
in Annex F.
Properties of the installed product shall be assessed in accordance with clause 5. To comply with document,
products shall meet the requirements of 4.2, and the requirements of 4.3 as appropriate.
One test result on a product property is the average of the measured values on the number of test specimens
given in table 1.
The declared thermal resistance level is for the installed insulation only, disregarding the effects of studs,
beams, rafters etc.
NOTE 1 EN ISO 10456 describes how the design thermal conductivity is calculated from the declared thermal
conductivity.
NOTE 2 For calculating the thermal resistance of complete building elements involving the use of these products the
procedures given in EN ISO 6946 can be used.
4.2 Installed declared thermal resistance of loft insulation
The installed declared thermal resistance shall be assessed by measure
