Thermal insulation products for building - Factory made vegetal fibres based products (VFBP)

This document specifies the characteristics 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 or boards. Products covered by this standard can also be used for acoustic applications. The standard also covers multi-layered boards. Products covered by this standard are also used in prefabricated insulating systems. The structural performance of systems incorporating these products is not covered by this standard.
This document 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. Products with a declared thermal conductivity at 10 °C, greater than 0,07 W/(m.K) or a declared thermal resistance lower than 0,20 m2/k/W are not covered by this standard. This standard does not cover in situ applied insulation and products intended to be used in the insulation of building equipment and industrial installations.

Overview

FprEN 17139 (prEN 17139:2017) is a draft CEN standard that defines requirements for factory-made vegetal fibres based products (VFBP) used for building thermal insulation. It covers products manufactured as rolls, felts, slabs or boards - with or without facings, coatings or integral reinforcement - and includes multi-layered boards and composite panels. The standard applies to products composed of at least 70% vegetal fibres by mass, and addresses thermal and basic hygro-physical characteristics relevant for building insulation and acoustic applications. Structural performance of systems that incorporate these materials is outside the scope.

Key Topics

• Product definition: Factory-made vegetal-fibre insulation (agro fibres, wood fibres, paper) containing ≥70% vegetal fibres by mass and not covered by EN 13171 (wood fibre standard).
• Scope exclusions: In-situ applied insulation, insulation for building equipment/industrial installations, and products with declared thermal conductivity at 10 °C greater than 0.08 W/(m·K) or declared thermal resistance below 0.20 m2·K/W are not covered.
• Forms and variations: Rolls, felts, slabs, boards, multi-layered boards, composites, with/without facings or reinforcements.
• Declared thermal values: Procedures for determining declared thermal conductivity and thermal resistance (Annex A), including moisture-related corrections (Annex D).
• Testing and conformity: Sampling, conditioning, and testing requirements are referenced to established EN test methods (e.g., EN 12667 / EN 12939 for thermal resistance, EN 1602 for density). Reaction-to-fire and acoustic test standards are included (EN 13501-1, EN 13823, EN ISO 354, etc.).
• Assessment & AVCP: Product Type Determination (PTD), Factory Production Control (FPC) and assessment procedures (AVCP) are specified; Annex ZA links to EU construction product legislation and CE marking requirements.
• Classification and labelling: Classification codes, marking and labelling requirements are provided to support consistent product information.

Applications

• Thermal insulation in building envelopes: walls, roofs, floors.
• Acoustic insulation uses in buildings (sound absorption and airflow resistance).
• Prefabricated insulating systems and composite panels where vegetal-fibre products are used as insulating layers. Users: manufacturers of sustainable insulation, product specifiers, architects, building engineers, testing laboratories, and conformity assessment bodies needing to evaluate or declare thermal and related properties for CE marking and market access in CEN member states.

Related Standards

• EN 13162 to EN 13171 series (factory-made thermal insulation products - mineral wool, EPS, XPS, PU, PF, CG, WW, WF, etc.)

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

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.

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.

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

5 Test methods
5.1 Sampling
Test specimens shall be taken from the same sample with a total area not less than 1 m and sufficient
to cover the needed tests. The shorter side of the sample shall not be less than 300 mm or full size of the
product whichever is the smaller.
5.2 Conditioning
No special conditioning of the test specimens is needed unless otherwise specified in the test standard.
In case of dispute, the test specimens shall be stored at (23 ± 2) °C and (50 ± 5) % relative humidity for
at least 24 h prior to testing. For FPC no special conditioning of the test specimens is needed.
When cut from boards, except for 5.3.2, test specimens shall be stored in an atmosphere of (23 ± 2) °C
and (50 ± 5) % relative humidity until stabilization at constant weight is achieved. Stabilization is
obtained when the relative change in weight does not exceed 0,5 % between two consecutive daily
measurements. In case of dispute, the following stepwise procedure shall be carried out:
— step 1 (dry reference): Constant mass is reached if the change of mass between three consecutive
weighings, each made at least 24 h apart, differs by less than 0,1 % of the total mass at (65 ± 2) °C,
in an oven ventilated with an air taken at (23 ± 2) °C and (50 ± 5) % relative humidity, and then
weighed. The mass of the test specimen at step 1 is m .
dry
— step 2 (normal reference): After conditioning according to step 1, the specimens are stored in an
atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity until stabilization, and then weighed.
Stabilization, by definition, is deemed to be reached if during the conditioning process, in two
subsequent weighing using a 24h interval, the change of mass between the two determinations is
less than 0,05 % of the total mass. The mass of the test specimen at step 2 is m .
