Overview
prEN 17237 - published by CEN - is the draft European specification for External Thermal Insulation Composite Systems with renders (ETICS). It defines the required characteristics, performance criteria, testing and marking for design ETICS kits supplied by a system holder and used as external thermal insulation on masonry or concrete walls. The standard covers ETICS where prefabricated insulation panels are bonded, mechanically fixed or both, and are overlaid by a site‑applied rendering system (one layer of which contains reinforcement). The render is applied directly to the insulation without an air gap.
Key topics and technical requirements
- Scope of coverage: ETICS for walls of masonry or concrete using insulation types listed in Annex B (cellular glass, EPS, expanded cork, mineral wool, phenolic foam, rigid polyurethane, XPS, wood fibre) provided they meet Annex B requirements.
- Kit definition: Composition of a design ETICS kit - insulation product, adhesive/mechanical fixings, reinforcement, base coat/top coat and ancillary components - and requirement that kits be installed per system‑holder instructions to achieve declared performance.
- Performance characteristics: Thermal resistance, pull‑through and pull‑off resistance, impact resistance, hygrothermal behaviour, reaction to fire classification, and factory production control. (Test methods are referenced; e.g., EN 13494, EN 13495, EN 13497, EN 16383, EN 13501‑1.)
- Exclusions and limits: Explicit limits on mass per unit area of renders and combined systems, insulation thickness limits, and minimum bonded area (coverage ≥ 40 %). EIFS (External Insulation and Finishing Systems) per ISO 17738 are not covered.
- Assessment & marking: Requirements for Assessment and Verification of Constancy of Performance (AVCP), factory production control, and labelling/marking provisions; integrated Annex ZA links the standard to Regulation (EU) No. 305/2011 (CPR).

European foreword
This document (prEN 17237:2018) 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 will supersede EN 13499:2003 and EN 13500:2003.
Upon publication of EN 17237, EN 13498:2002 will be withdrawn without replacement.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of the
EU Construction Products Regulation (CPR).
For relationship with the EU Regulation, 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 can
be used in other areas where appropriate.
Compared to EN 13499:2003 and EN 13500:2003, the following changes have been made:
a) the text is completely revised and both standards have been implemented in the approach of an
ETICS;
b) a new standard reference.
This European Standard contains four annexes:
— Annex A (normative) assessment of performance of the kit and assessment and verification of
constancy of performance;
— Annex B (normative) Characteristics and performance for thermal insulation products;
— Annex C (informative) Fire performance middle and large scale fire test;
— Annex D (normative) Calculation of safety-factor pull-through;
— Annex ZA (informative) Clauses of this European Standard addressing the provisions of the EU
Construction Products Regulation.
Introduction
This standard covers design External Thermal Insulation Composite Systems (design ETICS) with
rendering systems. Design ETICS kits are intended for use as external thermal insulation to the walls of
buildings. The walls are made of masonry (bricks, blocks, stones etc.) or concrete (cast on site or as
prefabricated panels) with or without rendering systems.
The standard describes characteristics and performance of design ETICS kits and marking and labelling
for design ETICS with rendering systems applied to thermal insulation products.
Design ETICS are placed on the market as different kits by a system holder, consisting of selected
components to improve the thermal insulation of buildings’ outside walls. Kits have to be installed
following system holders instructions to achieve the declared performance. They may include ancillary
products. Assembled kits provide protection against weathering and improve the appearance of the
buildings. They do not contribute to the stability of the wall, nor to the air tightness of the building.
1 Scope
This document specifies the characteristics and performance for design External Thermal Insulation
Composite Systems (design ETICS) with rendering systems on thermal insulation products, delivered as
a kit by a system holder, and used as thermal insulation for buildings.
This document covers design ETICS kits on walls which are made of masonry (bricks, blocks, stones,
etc.) or concrete (cast on site or as prefabricated panels) with or without rendering systems. This
document covers ETICS with thermal insulation products made of cellular glass, expanded polystyrene,
expanded cork, mineral wool, phenolic foam, rigid polyurethane foam, extruded polystyrene foam or
wood fibre as far as they comply with Annex B.
A design ETICS kit comprises a prefabricated insulation product bonded onto the wall, or mechanically
fixed using anchors, profiles, etc., or a combination of adhesive and mechanical fixings. The insulation
product is faced with a rendering system consisting of one or more layers (site applied), one of which
contains reinforcement. The rendering system is applied directly to the insulating panels, without an air
gap or disconnecting layer.
This document is not applicable for:
a) Mechanically fixed kits with supplementary adhesive with the mass per unit area of the rendering
system of > 40 kg/m in end use conditions intended by the system holder and/or mechanical fixed
kits with the mass per unit area of the rendering system plus thermal insulation product of
> 65 kg/m intended by the system holder.
b) Mechanically fixed kits without supplementary adhesive with the mass per unit area of the
rendering system of > 30 kg/m in end use conditions intended by the system holder and/or
mechanical fixed kits with the mass per unit area of the rendering system plus thermal insulation
product of > 60 kg/m intended by the system holder and/or with a thickness of the thermal
insulation product intended by the system holder of > 200 mm. For thermal insulations products
with thicknesses ≤ 200 mm fixed with anchors without supplementary adhesive, the bending
deformation of the mechanically fixing devices is assumed as negligible.
c) Purely bonded kits with or without supplementary mechanically fixing devices with bonded area
(coverage) less than 40 %, intended by the system holder.
d) Mechanically fixed kits with supplementary adhesive with bonded area (coverage) less than 40 %,
intended by the system holder.
e) Kits incorporating a thermal insulation product providing a declared thermal resistance of less than
1 m K/W.
External insulation and finishing systems (EIFS) according to ISO 17738 are not covered by this
standard.

Figure 1 — Description of design ETICS and kit in relation to construction works
Figure 1 shows the principles of design ETICS, the resultant kits and the relation to construction works.
Box 1 contains every product which can be used for a specific design ETICS kit. Only one base coat is
covered by one design ETICS. Some of the components are not mandatory. Commonly only a few of all
possible combinations of the products in box 1 are in visage by a system holder for a particular kit. Only
these combinations belong to the design ETICS. In short, the design ETICS consists of all products and
the intended combinations for kits thereof.
Box 1 contains four kit examples. The short dash line kit is only bonded by adhesive. The straight line
kit includes any kind of components. The grey line and the long dashes kits use reduced sets of
components. These four kit examples are also illustrated in Figure 2 a), b), d) and e).
Box 2 is applicable to construction works. It includes an assembled kit with ancillary products, box 3.
Ancillary products may be mastics, joint-covers, corner stripes, corner profiles, base profiles, fire
barriers, etc. They are necessary to complete a kit on site. Box 4 intends the assembled kit without
ancillary products. It includes the rendering system, box 5. The rendering system is made of the
reinforced base coat, box 6, and the finishing layer, box 7.
NOTE In some cases products of a design ETICS may have additional intended uses.
Ancillary products are used, e.g. to form joints or to achieve continuity or to give specific protection
(mastics, joint-covers, corner stripes, corner profiles, base profiles, fire barriers etc.). They are specified
by the system holder in order to ensure the performance, the safety and the durability of the system.
They are used in the assembled kit according to system holder’s application rules, but are not assessed
by this standard.
4.2 Description of an assembled kit
An assembled kit comprises a thermal insulation product fixed onto the external surface of a substrate.
The substrate is made of masonry (bricks, blocks, stones etc.) or concrete (cast on site or as
prefabricated panels). The thermal insulation product is faced by a rendering system consisting of a
reinforced base coat and a finishing layer. The reinforcement consists of glass fibre mesh or metal mesh,
incorporated in the base coat. The finishing layer consists of a finishing coat and an optional key coat
and/or decorative coat.
For fixing methods and typical thermal insulations products used see Table 1 — Fixing methods and
typical thermal insulation products used.

A kit may be fixed to the substrate in different ways:
a) purely bonded kit (a ): the kit is fully bonded (entire surface of the insulation product covered by
adhesive) or partially bonded in strips and/or dabs; purely bonded kit with supplementary
mechanical fixing devices (a ): the load is fully transferred to the substrate by the bonding layer.
The mechanical fixing devices are used to provide stability until the adhesive has cured and/or
dried. They act as a temporary fixing to prevent detachment;
b) mechanically fixed kit with supplementary adhesive: the wind load is considered to be fully
transferred to the substrate by the mechanical fixing devices. The dead load is considered to be
transferred by the supplementary adhesive;
c) mechanically fixed with profiles or rails and supplementary adhesive;
d) purely mechanically fixed with anchors: the kit is fixed to the wall by mechanical fixing devices
only;
e) Purely mechanically fixed by an anchored metal mesh.
An assembled kit consists of a specific set of products taken from a design ETICS and delivered by one
system holder and is applied onto the wall on site (see Figure 2 a) to e) — Examples of assembled kits
of a design ETICS).

4.3 ETICS components
4.3.1 Description of components
A component describes a group of factory-made products as a functional unit of the design ETICS.
The adhesive, base coat, finishing coat, key coat and decorative coat can include a range of binders from
organic to inorganic. They may be grouped according to the binder type into inorganic (cement-calcium
hydroxide, alkali silicate, etc.) and organic (silicon resin, synthetic resin, etc.) products.
They are available as:
— powder requiring addition of water (dry mortar);
— powder requiring addition of extra binder;
— paste requiring addition of cement;
— ready to use paste;
— ready to use PU-adhesive foam.
4.3.2 Adhesive
Component used for bonding the insulation product to the substrate; available as powder, paste or
PU-adhesive foam.
4.3.3 Thermal insulation product
A thermal insulation product is a factory-made thermal insulation material in its finished form,
including any facings or coatings and is intended to provide insulating properties to the kit and a
suitable substrate for the rendering system.
4.3.4 Rendering system
A rendering system consists of the reinforced base coat with finishing layer. It includes the following:
a) Base coat: Coating material applied directly by rendering to the thermal insulation product. The
reinforcement is embedded into it and provides most of the mechanical properties of the rendering
system. A base coat is available as powder or paste.
b) The glass fibre mesh or metal mesh is embedded in the base coat all over its entire area with a
minimum 10 cm overlap to ensure complete coverage.
NOTE It is possible to use a second mesh layer applied with or without overlapping.
c) Key coat: Very thin coating material which may be applied to the base coat as a preparation for the
application of the finishing coat. It may also be used for aesthetic reasons.
d) Finishing coat: Coating material which is applied to the reinforced base coat, with or without a key
coat. It mainly contributes to the protection against weathering and can provide a decorative coat.
A finishing coat is available as powder or paste.
Finishing coats are classified into one of the following groups:
1) Aggregate sized coats according to EN 15824: Each product is applied in one thickness. The
thickness of the finishing coat is slightly higher than the maximum grain size of the product.
2) Felt coat/modelling coat according to EN 15824: Each product is applied in a declared
thickness range above maximum grain size. Typical aggregates used for felt coats/modelling
coats provide sizes less than 1,5 mm. These coats provide a smooth surface or a modelled
surface after application depending on appropriate application tools and techniques.
3) Aggregate sized coats according to EN 998-1: Each product is applied in one thickness. The
thickness of the finishing coat is slightly higher than the maximum grain size of the product.
4) Felt coat/modelling coat according to EN 998-1: Each product is applied in a declared thickness
range above maximum grain size. Typical aggregates used for felt coats/modelling coats
provide sizes less than 1,5 mm. These coats provide a smooth surface or a modelled surface
after application depending on appropriate application tools and techniques.
5) Stippled structural coat according to EN 998-1: Each product is at a first stage applied in a
declared thickness. In a second stage the surface is scratched by a tool. Some aggregates with
higher grain sizes are scratched out, which leads to a typical roughness.
6) Other coats: Each product not belonging to groups 1) to 5), e.g. flexible brick slips or dry
dashed render.
e) Decorative coat: Coating material which may be applied to the finishing coat contributing to the
aesthetic finishing and protection against weathering.
4.3.5 Mechanical fixing device(s)
Mechanical fixing devices are used to fix a kit to the substrate with or without supplementary adhesives.
Different anchor types may be used:
a) to fix thermal insulation products and if appropriate also the reinforced base coat to the substrate
with supplementary adhesive;
b) to fix rails or profiles to the substrate;
c) to fix thermal insulation products and if appropriate also the reinforced base coat to the substrate
without supplementary adhesive;
d) to fix thermal insulation products by an anchored metal mesh, which is embedded in the base coat,
to the substrate without supplementary adhesive.
4.3.6 Ancillary products
An ancillary product is any supplementary component used in addition to the kit, which is used
according to system holder's instructions. Ancillary products are used e.g. to form joints or to achieve
continuity or to give specific protection (mastics, joint-covers, corner stripes, corner profiles, base
profiles, fire barriers etc.).
4.4 Worst case definition
A design ETICS may include many different configurations of kits. The system holder declares the
characteristics of every intended kit. However, not every single configuration needs to be tested.
Therefore the test result of a specific kit or part of a kit may also be valid for other kits or
configurations. The evaluation of such a range of configurations is called the "worst case evaluation".
The worst case evaluation is performed for every individual characteristic and can typically lead to
different kits or part of kits per characteristic to be tested. To cover every kit intended by the system
holder it may be necessary to define and test more than one worst case configuration per characteristic.
The rules for the identification of worst case configurations are given in this standard in Clause 5 and in
EN 16724 with regard to the reaction to fire according to EN 13501-1.
4.5 Assumptions for design of the construction works
4.5.1 Substrate inspection
It is necessary to ensure that the substrate is suitable for the intended fixing method and sufficiently
airtight.
4.5.2 Planning
The designer is required to supply all relevant documentation for the construction site. Such
documentation is the basis for choosing a suitable kit to meet the basic characteristics and performance
for construction works, as described below. Specific details like connections, joints, etc. are designed to
prevent water penetration. Additional structural elements, e.g. pipes, shall not damage the integrity of
the assembled kit to keep its performance.
4.5.2.1 Mechanical resistance and stability
Whilst the additional loads caused by an assembled kit normally do not lead to a significant risk in
terms of the load-bearing capacity of the construction, it is recommended that it is fully considered by a
suitably qualified structural engineer.
The seismic load resistance of the kit is not considered in this standard. Calculations may be based on
EN 1998-1.
4.5.2.2 Safety in case of fire
Characteristics and performance of fire safety depend on the building to which a kit is applied and are
fully considered by the designer.
4.5.2.3 Hygiene, health and the environment
For the release of dangerous substances to the soil, surface- and ground-water only leaching from the
finishing layer of the kit is considered.
NOTE An informative database covering European and national provisions on dangerous substances is
available at the Growth-Website on Europe access through http://ec.europe.eu/growth/tools-
database/cpds/index_en.htm.
4.5.2.4 Safety and accessibility in use
The chosen method of fixing of a kit to the substrate is laid down in the design and/or other relevant
documentation for the construction site. It is based on substrate characteristics and the chosen kit.
For Purely bonded kits and bonded kits with supplementary fixing devices it is recommended to
request a minimum value of bond strength of the adhesive to the substrate on-site of 80 kPa when
tested in-situ.
Purely mechanically fixed kits and mechanically fixed kits with supplementary adhesives: The
calculation of wind suction is done according to EN 1990 and EN 1991-1-4.
The wind load resistance of the kit is calculated by using relevant information out of the Declaration of
Performance of the design ETICS.
The wind load resistance of purely bonded kits is dependent upon the coverage area of the adhesive.
4.5.2.5 Protection against noise
The kit’s contribution to the airborne sound insulation of a building envelope can be calculated using
the relevant information out of the Declaration of Performance of the design ETICS.
4.5.2.6 Energy economy and heat retention
4.5.2.6.1 General
The heat transfer through an insulated wall is assessed on base of the calculation in 4.5.2.6.2.
4.5.2.6.2 Thermal resistance
4.5.2.6.2.1 Procedure of thermal resistance determination
The additional thermal resistance provided by a kit (R ) to the substrate wall is calculated from the
