European foreword

This document (prEN 17139:2017) 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 essential requirements of EU Directive.

For relationship with EU Directive, see informative Annex ZA which is an integral part of this document.

This European Standard is one of a series of standards for insulation products used in buildings, but this

standard may be used in other areas where appropriate.

In pursuance of Resolution BT 20/1993 revised, CEN/TC 88 have proposed defining the standards

listed below as a package of European Standards, setting 21 months after availability as the date of

withdrawal (dow) of national standards which conflict with the European Standards of this package.

The package of standards comprises the following group of interrelated standards for the specifications

of factory made thermal insulation products, all of which come within the scope of CEN/TC 88:

1 Scope

This European Standard specifies the requirements for factory made vegetal fibres based products

(VFBP), with or without facings or coatings and with or without integral reinforcement, which are used

for thermal insulation of buildings. Products are manufactured in form of rolls, felts, slabs or boards.

Products covered by this standard may also be used for acoustic applications. The standard also covers

multilayered boards and slabs and composites insulation boards and slabs. Products covered by this

standard are also used in prefabricated insulating systems and composites panels. The structural

performance of systems incorporating these products is not covered by this standard.

This European Standard applies to any thermal insulation products made of at least 70 % of vegetal

fibres per mass with or without the addition of bonding agents or bonding fibres and/or additives and

which don’t fall within the scope of the EN 13171. It does not replace the existing procedures for the

determination of the declared properties of products already covered by an existing harmonized

standard. This standard 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,

greater than 0,08 W/(m.K) or a declared thermal resistance lower than 0,20 m /k/W are not covered

by this standard. This European Standard does not cover in situ applied insulation and products

intended to be used in the insulation of building equipment and industrial installations.

4 Requirements
4.1 General

Product properties shall be assessed in accordance with Clause 5. To comply with this standard,

products shall meet the requirements of 4.2, and the requirements of 4.3 as appropriate.

NOTE Information on additional properties is given in Annex D.

One test result for a product property is the average of the measured values on the number of test

specimens given in Table 8.
4.2 For all applications
4.2.1 Thermal resistance and thermal conductivity

Thermal resistance and thermal conductivity shall be based upon measurements carried out in

accordance with EN 12667 or EN 12939 for thick products and in accordance with 5.2, 5.3.2 and

Annex C.

The thermal resistance and thermal conductivity shall be determined in accordance with Annex A and

declared by the manufacturer according to the following:
— the reference mean temperature shall be 10 °C;

— the declared values are to be given for a moisture content equal to the one the material has when

equilibrium with the air at 23 °C and relative humidity 50 %;
— the measured values shall be expressed with three significant figures;

— for products of uniform thickness, the declared thermal resistance, RD, shall always be declared.

The thermal conductivity, λD, shall be declared where possible. Where appropriate, for products of

non uniform thickness (i.e. for sloped and tapered products) only the thermal conductivity, λD,

shall be declared;

— the declared thermal resistance, RD, and the declared thermal conductivity, λD, shall be given as

limit values representing at least 90 % of the production, determined with a confidence level of

90 %;

— the statistical value of thermal conductivity, λ90/90, shall be rounded upwards to the nearest

0,001 W/(m⋅K) and declared as λD in levels with steps of 0,001 W/(m⋅K);
---------------------- Page: 13 ----------------------
oSIST prEN 17139:2017
prEN 17139:2017 (E)

— the declared thermal resistance, RD, shall be calculated from the nominal thickness, dN, or dL in

case of products with declared compressibility (see 4.3.11.3) and the corresponding thermal

conductivity, λ90/90, unless measured directly;

— the statistical value of thermal resistance, R90/90, when calculated from the nominal thickness, dN,

and the corresponding declared thermal conductivity, λ90/90, shall be rounded upwards to the

nearest 0,05 m2⋅K/W, and declared in levels with steps of 0,05 m2⋅K/W;

— the statistical value of thermal resistance R90/90, for those products for which only the thermal

resistance is measured directly, shall be rounded downwards to the nearest 0,05 m2⋅K/W and

declared as RD in levels with steps of 0,05 m2⋅K/W.

Examples of the determination of the declared values of thermal resistance, R , and the thermal

conductivity, λ , are given in Annex E.
λU and RU (design values) should be determined with reference to EN ISO 10456.
4.2.2 Length and width

Length, l, and width, b, shall be determined in accordance with EN 822. No test result shall deviate from

the nominal values by more than the following:
±2 % for length (for rolls, matts and felts no upper limit),
±1,5 % for width.
4.2.3 Thickness

Thickness, d, for products not intended for floating floors shall be determined in accordance with

EN 823 under a load of (250 ± 5) Pa except for products with a level of compressive stress or strength

of ≤ 10 kPa, where the load shall be (50 ± 5) Pa. No test result shall deviate from the nominal thickness,

d , by more than the tolerances given in Table 1 for the declared level or class.
