ČSN EN 13171+A1

This European Standard specifies the requirements for factory made wood fibre (WF) products, with or without facings or coatings, which are used for the thermal insulation of buildings ). The products are manufactured in the form of rolls, batts, felts, boards or slabs.
Products covered by this standard are also used in prefabricated thermal insulation systems and composite panels; the performance of systems incorporating these products is not covered.
This standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling.
Compared with EN 13171:2008, the main changes are:
a) better harmonisation between the individual standards of the package (EN 13162 to EN 13171) on definitions, requirements, classes and levels;
b) new normative annex on multi-layer products;
c) changes of some editorial and technical content and addition of information on some specific items such as for WF: determination of thermal conductivity in relation to moisture content, thickness, compressive stress or compressive strength, tensile strength perpendicular to faces;
d) addition of links to EN 15715, Thermal insulation products - Instructions for mounting and fixing for reaction to fire testing - Factory made products;
e) changes of Annex ZA.
