ETICS competency
Are you absolutely sure what is behind the old rendering?
ETICS are often used in renovation. The major part of the
structural fabric is of bad quality or combined masonry wasused. The bearing capacity of the old render is reduced
through environmental stress.
The ejotherm anchor generation provides safety. Especially
the ejotherm STR U can be used in any substrate. As the
first 8 mm ETICS anchor, it obtained a European Technical
Approval for all building material categories. Despite shortest
anchorage depths, it reaches the highest characteristic loads.
With EJOT quality your service promise will not hang by
a thread…

„I cannot afford a construction site to stagnate due to
installation problems, and even worse customer
complaints. Today, everything has to be fast and
smooth – but without reduction of quality and
security. EJOT anchors are great to work with.
Especially the STR principle is simply ingenious.
100% setting control and homogeneous insulation
surfaces – thus I can still relax after many years.“

„To me as a planer, energy savings and the design of a new ETICS
facade are most important. Moreover I am responsible that the
facade is secure and immaculate even after years – this is what the
client expects. That is why we advertise ejotherm STR U. If neces-
sary, EJOT experts already consult me during the bidding process
– even right on the building site.“

During more than three decades, over 500,000,000 sqm
of ETICS facades have been fastened with EJOT anchors
– without even a single incident! This equals an area of morethan 70,000 football pitches. Roughly 150 billion litres of
heating oil or 440 million tons of CO2 have been saved – a
valuable contribution to the environment, which is growing
daily.
More and more international customers and principals rely on
sophisticated fastening solutions and the competent advice
by EJOT.

For long-lasting beautiful facades
With its STR principle, EJOT has developed a unique fasten-
ing system. Without any additional work, the anchor washers
are installed countersunk and covered with an insulation cap.
This creates a homogenous surface and an even rendering,
which helps to avoid anchor marks.
For all substrates
The ejotherm STR U is the first 8 mm ETICS anchor with
European approval for all building materials, including gas
concrete (use categories A - E). For fastenings on wooden
materials we provide ejotherm STR H. Both anchors are
installed with the same ejotherm STR tool.
For all insulation materials
Both ejotherm STR U and ejotherm STR H can be either
installed countersunk according to the STR principle or plain
with the surface with the STR plug. This way an adaptation to
all commonly used types of insulation is possible.
Quality and safety in XXXL
The EJOT STR princple is available for insulation of up to
400 mm – the perfect fastening system for zero- and low-
energy houses.

ejotherm washer anchors
When fastening ETICS, insulation boards are usually attached
to the facade with adhesive and then fastened with anchors.
The bearing load of the system is carried onto the facadevia shearing forces. High-quality washer anchors, installed
through the insulation, guarantee additional contact pressure
through their stiff washers. This contact pressure supports the
permanent frictional bonding between adhesive and substruc-
ture. Due to a strong hold in the wall and the contact pressure
of the washer the clamping of the insulation board is ensured
(„screw clamp effect“).
ejotherm washer anchors with European Technical Approval
offer certif ied safety even under high wind loads. Through their
washers and the expansion element, they redirect the tensile
load into the bearing substructure.
The washer anchors of the ejotherm generation make things
easy for you:
Easy anchor choice for safe anchoring in any building material.
Together with a minimum anchor depth and maximum per-
formance. Performance up, total cost down! For long-lasting,
energy-saving facades.

Additional plates
The washer diameter is enlarged through specially matchedadditional washers. In this way the EJOT washer anchor isperfectly fitted to the demands of different insulation mate-rials. What additional washer is used in a specific case,
depends on the specifications of the ETIC system owner.
When combining our additional washers with ejothermSTR U or ejotherm STR H for the installation flush with thesurface, the special STR closing plugs have to be mounted.
When using additional washers the STR principle cannot beapplied.

ejotherm anchors for rail fastenings
A special kind of External Thermal Insulation Composite
Systems is the mechanical xing of the insulation boards with
the help of holding rails. These systems are preferably used onold facades with large tolerances (unevenness of the old
render) or signicantly damaged old render (lose parts,
partially missing old render).
Holding rails of plastic or aluminium are directly fastened on
the substrate with special collar head anchors. Our spacers
EJOT AS balance tolerances and bridge missing parts.
Simply clip the chosen thickness onto the anchor between
wall and holding rail. System-specic insulation boards are
put into the proles of holding rails through incorporated
grooves.
For additional anchoring of the insulation in the centre of the
board, we recommend our cap anchor ejotherm STR U (see
page 18).

The energy optimisation of the building envelope is closely
intertwined with insulating the ceiling on the lowest level.
Especially next to unheated rooms like basements, garages,
warehouses or passages ...
Moreover ceiling insulation is employed to improve acoustics.
It is used for example as noise insulation in commercially used
rooms or halls or as noise protection in shooting ranges.

To harmonise the EU single market the EU Commission
issued a directive on construction parts (89/106 EWG).
It determines which building parts need to comply with the
following essential requirements regarding their intended
use:
l mechanical resistance and stability
l safety in case of fire
l hygiene, health and the environment
l safety in use
l protection against noise
l energy economy and heat retention
Working groups of the European Organisation for Technical
Approvals (EOTA ) have elaborated criteria on how to preci-sely prove these requirements are fulfilled for ETICS. These
criteria and corresponding testing methods are stated in the
European Technical Approval Guidelines (ETAG). For ETICS
the following guidelines are relevant:
l ETAG 004: external thermal insulation composite systems
with rendering
l ETAG 014: plastic anchors for fixing external thermal
insulation composite systems with rendering
l CUAP according to the relevant ETAG
These guidelines are mandatory for all member states of the
European Union (EU) as for well as those states of the Euro-
pean Free Trade Association (EFTA ), that have signed the
agreements of the European Economic Area (EEA ), Iceland,
Liechtenstein and Norway. The guidelines form the base for
awarding European Technical Approval (ETA ) for individual
products. Construction parts with ETA and certificate of
conformity may carry the CE mark, which enables the free
movement of goods within the member states of the EEA.
This way a uniform appraisal of construction parts and theirfundamental technical specifications is ensured. Therefore
each member state can assume without further testing that
the construction part is generally suitable for the intended
use if planning and construction are done correctly. Never-
theless, the CE mark may not be regarded as a quality mark.
The guidelines assume a prospective useful life of ETICS
of at least 25 years. In accordance with current practical
experiences, the actual useful life may be much longer wit-
hout having to fear fundamental quality impairment. In spite
of that, a guarantee towards the system owner or singlecomponents cannot be inferred.
When processing the products, national requirements
are to be regarded. This way, member states may expli-
citly incorporate specific national or regional requirements
(e.g. different wind loads, safety factors, country-specific
construction methods).
In terms of the EC guideline on construction parts, external
thermal insulation composite systems are kits. The produ-
cer whose system receives an ETA is responsible for care-
fully choosing the single constituents. In accordance with
ETAG 004, components of an ETICS are:
l adhesive
l insulation product
l rendering system (including mesh reinforcement)
l mechanical fixing devices (anchors, holding rails)l ancillary materials (e.g. corner strips and base profile)
The approval lapses if components of various system
owners are used. This constitutes a breach of the building
code that leads to the loss of the warrantee by the owner
and may have legal consequences.
EJOT advises: Buy all system components
exclusively from the provider of an approved system!
An ETICS itself does not contribute to the structural stabi-lity of a building. Especially in renovation the stability of the
wall construction has to be checked if an ETICS shall be
installed. Since it has to carry the dead load of the insulation
system after renovation, the stability might have to be rebuilt
before attaching an ETICS. In particular this effects wall
constructions of multiple shells (buildings with a prewall shell
and precast concrete slab-type constructions).

Good reasons for anchoring an ETICS
Weathered facade
Facade renovated
with an ETICS
Safe installation on old facades
ETICS are often used for energy efficient refurbishment of
old buildings. Do you know how much load the old render
can actually carry? For decades it was exposed to weather
and emissions, soot, dirt and old paint reduce the bearing
strength of the glue. Or single components are not compa-
tible with the composition of the glue (“saponifying”). After
installing a new ETICS building physics can change the
bearing capacity of the old render (failure of old render) even
after years. Regarding new buildings residues of release oil on
concrete may cause difficulties. Cleaning a facade is complex
and costly. Contaminated waste water has to be collected
and professionally disposed. Furthermore the old render is
imbued when thoroughly cleaned.
However if insulation boards are additionally anchored, usu-
ally no special treatment of the facade is necessary. Only
loose parts of the render, efflorescence and paint flaking off
need to be roughly removed. Possible holes are filled. Even-
tually anchors provide safe support…
Highest structural stability
When insulation boards are solely glued, the deadweight of
an ETICS is passed onto the wall through shearing forces.
The used glue is therefore the only connection between wall
and insulation. Thanks to their specifically solid anchor plate
and high characteristic loads, ejotherm plate anchors give
your facade safe support. Through contact pressure the fric-
tional bond between facade surface and adhesive as well as
between adhesive and insulation board is steadily increased.
This results in a higher stability of the whole system. More-
over anchors with steel screw or steel nail offer higher safety
reserves.
Impact of anchoring:
– dead load of the system is passed on via adhesive and
insulation
– plate anchors provide additional contact pressure
Advantages:
– highest stability for the hole system
– anchor plates divert wind load
– highest security in case of wind loads

Judginig the substructure
The expansion zone of an anchor has to perfectly fit the wall
substrate found at the building. It is the only way the anchor
can optimally fulfil its function within the ETIC system. This is
why carefully assessing the substructure is highly important.
ETAG 014 (guideline for anchors in external thermal insula-
tion composite systems) distinguishes standard substrates
according to so-called use categories in order to facilitate the
assignment of the matching anchor.
Substrates
Determining the anchor type for the substrate
After the substructure is determined, the proper anchor can
be assigned with its approval since anchors with ETA are
tested and approved for specific use categories. The fol-
lowing cases are possible:
Case 1: The anchor is approved for the determined building
material category. The identified substrate is mentioned in the
ETA of the anchor.
The anchor may be used on the building without further
testing. The loads given in the approval can be used offhand
for calculating the necessary number of anchors. Where
required, national safety factors need to be observed.
Example:
Solid lime sandstone was determined as wall substrate.
This corresponds to use category B. The anchor has an
ETA for use categories A and B. For solid lime sandstones,
the ETA mentions a characteristic load of 1.2 kN. Natio-
nal rules require a security value of 3 for use category B.
Therefore the anchor can be calculated having a design load of
1.2 kN : 3 = 0.4 kN without further testing on the building.
Case 2: The anchor has no approval for the determined buil-
ding material category.
If the determined substrate at the building does not belong to
a use category for which the anchor is approved according to
the ETA, the anchor may not be used on this object. In this
case, the usability of the anchor cannot be proven through
pull-out tests.
Example:
Vertical coring bricks were determined as wall substrate. This
corresponds to use category C. An anchor only approved foruse categories A and B may not be used.

Use category B:Solid masonry
Use category C:Hollow or perforatedmasonry
Use category D:Lightweight aggregateconcrete
Use category E: Autoclaved aeratedconcrete

EJOT anchor basics
Case 3: The anchor is generally approved for the determined
building material category, but the identified substrate is not
explicitly named in the ETA of the anchor.
The anchor may be used if its usability is proven through tests
on the building. The object specific characteristic loads are
determined through pull-out tests as described in the ETA.
When deducting the design load national safety factors need
to be incorporated.
Example:
Perforated lime sandstone was determined as wall substrate.
This corresponds to use category C. The anchor has an ETA
for use categories A, B, C and D. Nevertheless, perforated
lime sandstone is not explicitly named in the ETA. Pull-outtests with this anchor on the object result in a characteristic
load of 1.5 kN. National rules require a security value of 3
for use category C. The anchor can be calculated having an
design load of 1.5 kN : 3 = 0.5 kN.
Case 4: The anchor is generally approved for the determined
building material category. The identified substrate is already
mentioned in the ETA of the anchor, but the gross density or
the compression strength of the stone differs from the decla-
ration of the approval.
In principle this case corresponds to case 3. The usability for
the substructure can be proven through tests on the building.
Special case: Weather shells of concrete (precast concrete
slab-type construction) are assigned to use category A. With
any ejotherm anchor the loads may be calculated employing
tests on the building.
EJOT advises:l The ejotherm STR U (as plate anchor) as well as the
ejotherm SDK U (for fastening rails) have a European
Technical Approval for all building material classes. Many
substrates are already tested for the approval and named
in the ETA. Therefore usually no additional tests are
necessary.
l Should tests on the building site be needed, you have
EJOT’s service at your hand.
Further criteria for choosing the perfect anchor
If in principal several anchor types are applicable in the found
building material, further assessment criteria can be emplo-
yed.
Additonal plates depending on the application
Ways to perfect anchoring

2 A bigger range of application offers more securit y regarding uctua ting
substrate qualities and mixed masonry.
3Please note possible differences between effective and nominal anchorage
depth when comparing with other products.
Depending on the application, our ETICS anchors are com-
bined with additional plates. The additional plates are very
simple to use and are available in various diameters. They are
put on the plate anchor like a washer. The further installationis processed as usual. In which case a specific additional
plate is applied, depends on the used insulation and the
system configuration. Crucial are the specifications of the
system owner.
Note: Additional plates are system components of the
anchor. They are tested accordingly and described in the
approval of the anchor. Therefore plate anchors may only be
combined with the matching additional plates by the same
manufacturer.

Determining the necessary anchor length
The correct determination of the anchor length is an impor-
tant prerequisite to obtain the highest fastening safety pos-
sible. The object specific preconditions always have to be
taken into account, but determining the necessary anchorage
length itself is easy:
nominal anchorage depth hnom+ tolerance compensation ttol+ insulation thickness hD= necessary anchor length lD
h1 = drill hole depthhef = effective anchorage depthhnom = nominal anchorage depth (>_ hef )ttol = tolerance compensationhD = insulation thickness
Notes:
If no other specifications are given, the nominal anchorage
depth hnom is equal to the effective anchorage depth hef .
The tolerance compensation consists of: thickness of old render (if existent, the old render often is
approx. 20 mm thick)+ thickness of the adhesive joint after pressing the insula-
tion boards against the wall (as a rule approx. 10 mm)*+ additional compensation of facade unevenness*= tolerance compensation ttol
If during the energetic renovation there is a larger facade
unevenness to compensate, it may be necessary to employ
different anchor lengths.
Determining the necessary number of anchors
The necessary number of anchors has to be determined
for each building individually. According to new European
and national wind load standards several factors have to be
incorporated. Amongst the most essential influences are the
building construction (height, ground plan, profile) as well
as the surroundings of the building. Exposed conditions in
coastal areas, on mountains or outside closed housing areas
normally lead to significantly higher wind loads. Details and
actual maps with zones of different wind loads are part of
national standards.
From the system point of view the anchor usage is increased
by the bearing load of the used insulation board as well as
the characteristic load and the plate stiffness of the emplo-yed anchors. Therefore the working guidelines of the ETICS
provider have to be observed.
Generally speaking: the higher the building and the more
exposed its surrounding area, the higher the necessary
number of anchors. On the other hand high-quality anchors
often mean a lower usage of anchors per square metre – and
thus save material cost and working hours.
Correct processing is crucial for the function of the
anchor
The position of the anchor results from the anchor scheme
of the ETIC system owner. Common anchorage alignments
are for example:
l alignment of anchors for insulation boards with formats
1000 x 500 mm, e.g. rigid foam plates of polystyrene and
800 x 625 mm, e.g. mineral wool plates (table 1)
l alignment of anchors for insulation boards with formats
1000 x 200 mm, e.g. lamella plates of mineral wool(table 2)
Anchors should always be installed in the area of the adhe-
sive, so that they can support the adhesive joint by means of
contact pressure in the best way possible.
* Facade tolerances are eventually compensated through the actual total thicknessof the adhesive mortar.

EJOT advises:
When drilling in rotary mode (without percussion), use our
special drills to achieve a clean hole in a short time.
Drills are wearing parts. Their durability depends on the
solidness of the substructure: The harder it is, the higher the
abrasion. To achieve an efficient work progress, drills should
be exchanged in time.
When drilling, please exactly follow the specified installation
values of the individual anchor type (especially the minimum
drilling hole depth). The exact geometry of the drill hole is
important for the bearing capacity of the anchor. Therefore
always drill on a 90 degree angle and never change direction
while drilling. This is especially important with regards to softsubstrates. Before inserting the anchor clean the hole from
drill dust by pulling out the drill several times.
With regards to plate anchors the anchor plates are either
installed countersunk into the insulation board following the
EJOT STR principle or plain with the surface on the insulation
exterior (always in combination with additional plates). When
installing plain with the surface it should be regarded that
the upper side of the anchor plate forms one level with the
upper side of the insulation. When the plate moves in too
deeply, the cavity needs to be levelled out before installing
the mesh. This leads to heightened plaster in the area of the
plate and bears the risk of cracking plaster. When the plate
does not enter deep enough, a thicker mesh layer has to be
installed over the whole facade in order to achieve the mini-
mum render thickness over the anchor plates. This results in
higher costs.
EJOT advises: When using the EJOT STR principle, the
anchor plate is quickly and cleanly countersunk into the
insulation and covered with an STR cap. This way a smoothand homogenous insulation surface as basis for an even
rendering is established. No additional work for levelling out
the anchor plates is needed. Moreover, the anchor plates are
detached from the rendering.
