6 ETICS competency Your service Our quality: EJOT philosophy sets standards 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 was used. 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

7 ETICS competency I cannot afford a construction site to stagnate due to installation problems. And even worse are 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. 7

14 The EJOT STR principle Your guarantee Our STR principle For long-lasting beautiful facades With its STR principle, EJOT has developed a unique fastening system. Without any additional work, the anchor plates are installed countersunk and covered with an insulation cap. This creates a homogenous surface and an even rendering, and 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. Easy installation: Quick drilling thanks to reduced drill depth Put anchor with pre-mounted screw into the hole until the plate bears on the surface Screw with the STR tool: countersinking happens automatically (no milling, no dust) Insert the STR insulation cap ready! 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 XXL The EJOT STR princple is available for insulation of up to 360 mm the perfect fastening system for zero- and lowenergy houses. 14

15 ejotherm plate anchors ejotherm plate anchors anchor choice made easy When fastening an 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 facade via shearing forces. High-quality plate anchors installed through the insulation guarantee additional contact pressure through their stiff plates. This contact pressure supports the permanent frictional bonding between adhesive and substructure. Through a powerful anchoring in the wall and the contact pressure of the plate, the tension of the insulation releases ( screw clamp effect ). ejotherm plate anchors with European Technical Approval offer certified safety even under high wind loads. Through their plates and the expansion element, they redirect the tensile load into the bearing substructure. The plate 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 performance. Performance up, total cost down! For long-lasting, energy-saving facades. 15

23 ejotherm anchors for rail fastenings ejotherm anchors for rail-fixed ETICS A special kind of External Thermal Insulation Composite Systems is the mechanical fixing of the insulation boards with the help of holding rails. These systems are preferably used on old facades with large tolerances (unevenness of the old render) or significantly 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 ready! System-specific insulation boards are put into the profiles 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 16). For problematic substrates we offer our special anchor EJOT SDF-K plus 8 U (page 31). 23

27 EJOT anchors for clinker systems EJOT anchors for prefabricated ETICS with clinker External Thermal Insulation Composite Systems open a multitude of optical design scopes to significantly improve energy efficiency and outlook at the same time when renovating a facade. Besides different renderings and colourings, ceramic claddings have become increasingly popular. Due to the significantly higher mass per unit area, clinker-built ETICS are generally anchored. ETICS with facing clinker that is already glued on the insulation board usually allow for a purely mechanical fastening with special countersunk anchors directly to the facade. The holes are almost invisible at the joint pattern. If the ceramic cladding is glued on after the anchoring, either completely or in parts, it is recommendable to use ejotherm plate anchors. When using the cap anchor ejotherm STR U with cap, an advantageous decoupling of the facing clinker from the anchor plates is achieved. 27

32 Solutions for special applications Renovation of two-shell masonry When renovating old building fabric, it may be required by law to check the stability of the wall before installing ETICS. If necessary, the stability needs to be rebuilt at first. On two-shell wall constructions with facing shells, anchors from zinc-coated steel were used in the late 70 s for the first time. Their stability is often not safe due to advanced corrosion. With the EJOT VSD, the stability can be rebuilt.

39 anchor 10 Building laws background EJOT anchor basics 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: When processing the products, national requirements are to be regarded. This way, member states may explicitly incorporate specific national or regional requirements (e.g. different wind loads, safety factors, country-specific construction methods). 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 precisely 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 European 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 their fundamental 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. Nevertheless, the CE mark may not be regarded as a quality mark. In terms of the EC guideline on construction parts, external thermal insulation composite systems are kits. The producer whose system receives an ETA is responsible for carefully 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 stability 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). 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 without having to fear fundamental quality impairment. In spite of that, a guarantee towards the system owner or single components cannot be inferred. 39

40 anchor 10 Good reasons for anchoring ETICS EJOT anchor basics Safe installation on old facades ETICS are often used for energetic insulation 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 compatible 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. Moreover the old render is imbued when thoroughly cleaned. 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 frictional 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. Moreover anchors with steel screw or steel nail offer higher safety reserves. Safe is safe! But if insulation boards are additionally anchored, usually 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. Eventually anchors provide safe support Weathered facade Z D Q Facade renovated with an ETICS 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 40

41 EJOT anchor basics 1Good reasons for anchoring an ETICS Highest security against hygrothermal impacts Hygrothermal influences like temperature changes and shrinkage lead to fluctuating material expansion that effect the inelastic adhesive joints. If solely glued there is a latent danger of the insulation boards to bulge due to lacking expansion possibility at the joints. The additional anchoring in the area of the joints as well as in the centre of the board results in a mechanical fixing of the system onto the wall and therefore reduces the risk of cracking plaster. Highest security against wind loads Wind loads affect in the opposite direction of the deadweight. They provide for a vertical tensile load onto the adhesive joint. Special importance is attached to the intersection of wall/ adhesive (new buildings) and of old render/adhesive (renovation) respectively as well as of adhesive/insulation. Particularly high wind loads exist l at higher buildings l at building edges l at free-standing buildings l in exposed areas l in coastal areas l in stormy weather warm outside cold outside Therefore: Climate scientists assume that the risk of heavy storms and grave damages will increase worldwide. EJOT anchors provide additional security! Additional fixing of the insulation boards with ETICS anchors by EJOT 41

42 anchor 10 Ways to perfect anchoring EJOT anchor basics 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. 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 following cases are possible: ETAG 014 (guideline for anchors in external thermal insulation composite systems) distinguishes standard substrates according to so-called use categories in order to facilitate the assignment of the matching anchor. Substrates Use category A: Normal weight concrete Use category B: Solid masonry 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. National 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 building material category. Use category C: Hollow or perforated masonry Use category D: Lightweight aggregate concrete 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 for use categories A and B may not be used. Use category E: Autoclaved aerated concrete 42

43 1 EJOT Ways to perfect anchoring 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-out tests 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 declaration 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. anchor basics 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 employed. Example ejotherm STR U 100% setting control 3 1) Homogenous insulation surface 3 Even rendering 3 Permanent contact pressure 3 Less work thanks to premounted expansion element 3 Installation behaviour ++ Loads ++ Reduction of thermal bridges + Range of use 2 ++ Anchorage depth When applying the STR principle for countersunk installation. 2 A bigger range of application offers more security regarding fluctuating substrate qualities and mixed masonry. 3 Please note possible differences between effective and nominal anchorage depth when comparing with other products. Additonal plates depending on the application Depending on the application, our ETICS anchors are combined 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 installation is 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. 43

44 anchor 10 Ways to perfect anchoring EJOT anchor basics Determining the necessary anchor length The correct determination of the anchor length is an important prerequisite to obtain the highest fastening safety possible. The object specific preconditions always have to be taken into account. But determining the necessary anchorage length itself is easy: nominal anchorage depth h nom + tolerance compensation t tol + insulation thickness h D = necessary anchor length l D 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. h 1 h ef = h nom t tol h D 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 employed 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. h 1 = drill hole depth h ef = effective anchorage depth h nom = nominal anchorage depth (>_ h ef ) t tol = tolerance compensation = insulation thickness h D Notes: If no other specifications are given, the nominal anchorage depth h nom is equal to the effective anchorage depth h ef. 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 insulation boards against the wall (as a rule approx. 10 mm)* + additional compensation of facade unevenness* = tolerance compensation t tol 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 adhesive, so that they can support the adhesive joint by means of contact pressure in the best way possible. If during the energetic renovation there is a larger facade unevenness to compensate, it may be necessary to employ different anchor lengths. * Facade tolerances are eventually compensated through the actual total thickness of the adhesive mortar. 44

46 anchor 10 Ways to perfect anchoring EJOT anchor basics Drilling methods Depending on the drilling machine and the hammer drill respectively, the following drilling methods are possible: l rotary drilling - without percussion l percussion drilling - many percussions with low energy l hammer drilling - few percussions with high energy rotary drilling percussion drilling hammer drilling Standard carbide drill for percussion and hammer drilling EJOT special drill for clean rotary drilling The drilling method is dependent upon the individual anchorage substructure. It is given in the following table. Use category A B C D E Drilling method percussion/ rotary drilling without hammer drilling percussion 46

47 EJOT anchor basics Ways to perfect anchoring 1EJOT 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 orthogonally and never change direction while drilling. This is especially important with regards to soft substrates. Before inserting the anchor clean the hole from drill dust by pulling out the drill several times. Plate moves in too deeply 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 minimum render thickness over the anchor plates. This results in higher costs. Plate not deep enough 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 smooth and 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. Perfect: installation of ejotherm STR with cap 47
