// external wall insulation Saved energy is the most cost-effective and accessible energy The Rockwool Group is the world s leading producer of stone wool. Our mission is to be the preferred supplier of products, systems and solutions for improved energy efficiency, acoustic performance and fire safety in buildings. The energy consumption in buildings is about 40% of the energy used in Europe and the U.S.A. Heating and air conditioning are the main energy consumers. However, most of this energy is wasted due to inadequate insulation. Using well-proven energy efficiency technologies, the energy consumption in buildings needed for heating can be cut up to 90%. Rockwool insulation provides pleasant indoor environment by keeping out the cold. In hot climate regions, stone wool helps keeping rooms comfortably cool. Rockwool products improve the quality of life for millions of people and help to alleviate environmental problems, such as the green house effect, smog and acid rains. Rockwool insulation products are one of the few products that can save more than 100 times the energy used for its manufacture. It conserves scarce energy resources and reduces air pollution and CO 2 emissions by minimizing the combustion of fossil fuels.

external wall insulation // More than energy saving Rendered facade systems with Rockwool stone wool Properly installed facade insulation ensures permanent savings on heating costs. Non-insulated facade A thermo-graphic camera clearly shows hot spots on facade where the heat energy directly goes out of the building through external walls. The stone wool insulation contributes to lower heating costs Energy prices keep increasing every year. Investment in the energy saving system today will bring a profit only tomorrow. Heating costs are one of the highest costs for every household and that is the point of the biggest potential for saving. There are three major ways to improve the energy efficiency of buildings: window replacements, heating system modernization and additional thermal insulation on facades. Improvement of the thermal insulation properties by application of additional facade insulation would very soon result in energy saving. The rendered facade systems with Rockwool stone wool ensure maximum savings and additionally improve the microclimate and comfort inside buildings. Also they are non-combustible, vapour permeable, durable and environmental friendly. (Data source: Emnid survey Zukunft Haus 2003 for Deutsche Energie-Agentur http://www.zukunft-haus.info) Energy consumption Prevailing conviction Vehicles I don t know Hot water Electrical appliances Heating Real consumption Heating Hot water Vehicles Electrical appliances Household heating energy consumption is rather underestimated in people s minds. 74% are not aware that they spend more than half of resources intended for the energy supply on heating. More than one third of them wrongly think that the electrical appliance consumption is higher as they don't have a proper understanding of total cost of energy.

// external wall insulation Rockwool products offer an unrivalled combination of thermal, fire, acoustic and enviromental properties Efficient thermal protection and low heating costs With Rockwool solutions the thermal demands of today s building regulations can be easily met and low-energy designs are externally enriched with exciting and aesthetic finishes. Energy efficiency in buildings including the use of insulation systems comprises technologies immediately at hand and holds the largest potential for profitable savings. The usefulness of Rockwool insulation in buildings is that it not only reduces CO 2 emissions, but also saves money by saving energy. Low thermal conductivity coefficient of the stone wool guarantees minimal thermal loss. In other words, the heat shall remain just where we wish, i.e. in the interior of a building. Therefore, building s energy needs are substantially lower than usual, since the inside stays uniform and we can feel immediately that the indoor climate is significantly better. Apart form saving on heating cost, we also gain pleasantly healthy and comfortable housing conditions. Excellent acoustic performance Rockwool has excellent acoustic properties. Using Rockwool on the wall construction can make appreciable improvements in sound absorption. Long-lasting exposure to noise may cause severe health problems. While choosing insulation, stone wool is certainly the right choice being a combination of excellent thermal insulation properties and maximum absorption of acoustic vibration. The texture of intertwined short fibers in stone wool guarantees excellent noise absorption and good thermal insulation. Upon installation on the external facade walls, as well as in the core of partition walls, stone wool substantially reduces the noise level in room, thus providing comfortable and healthy environment in a house. High fire safety guarantees secure housing Fire safety of every building can be of vital importance. Insurance companies, while calculating premium, frequently recognize advantages of buildings constructed from noncombustible materials and in accordance with provisions on fire safety. Materials that in case of fire do not accelerate the fire spreading and do not cause dense smoke spreading or burning particles, as well as gas emitting that might lead to an explosion, according to the standard EN 13501-1 are classified in A1 class of noncombustible materials. Rockwool stone wool has a melting point higher than 1000 C and therefore it is classified as a non-combustible material. Installation of the class A insulation provides, in case of fire, crucial seconds needed for the building evacuation and saving precious lives. Rockwool external wall insulation slabs have excellent fire properties and are classified as A1 to ISO 1182, the best achievable fire performance category. With the facts at your disposal, you can specify Rockwool external wall insulation with confidence as part of your proactive approach to fire safety.

external wall insulation // Walls without dampness guarantee comfortable indoor climate Breathing of walls in the real sense of this word is guaranteed when the stone wool is chosen for insulation. In any building, moisture must be ventilated out of the building. Vapour permeable texture of stone wool ensures a free passing of moisture through external walls from the inside towards the outside. The risk of moisture retaining in the walls is a minimal one, thus a probability of appearing harmful mould on their surface is decreased. Mould usually grows on cold external walls of a room with high relative humidity (bedroom, kitchen), and can be harmful to the respiratory system. The experience will not cause discomfort nor any disease or allergies. By insulating walls with stone wool on the external side, walls remain warm, so you can never risk warm humid air condensing on cold, poorly insulated surfaces which will create moisture. Positive energy balance and responsibility towards the environment The management of energy resources and industrial waste material is one of the key facts in the production planning. With the aim of decreasing impacts on the environment, Rockwool has designed its production process as a closed system where all wastes are recycled and thus returned to the production process. Therefore, the energy demand is decreasing and, at the same time, it benefits the environment. Rockwool mineral wool products are recyclable. To reduce the burden on landfill sites and to help minimize the depletion of resources, Rockwool encourages the return of Rockwool off-cuts and Rockwool product reclaimed from refurbishment or demolition work, to be recycled. All these activities directly influence the so-called energy balance of the stone wool. When compared to other building and insulation materials, the balance of Rockwool stone wool is distinctly advantageous. Costs of energy used for the production of stone wool will be paid off in a few years through energy saving for heating. Durability of material and low costs of maintenance Rockwool stone wool retains its insulation properties over long periods and it is fully resistant to the outdoor climate effects and weathering. Due to its dimension stability, stone wool does not cause cracks in the facade and does not absorb moisture that causes mould growing on the external facade surface. In addition, stone wool is an unfit material to insect developing or other creatures that might settle down in certain organic thermal insulation materials. Therefore, the maintenance cost of rendered facade systems with Rockwool stone wool is considerably lower when compared to other thermal insulation types.

Ground floor, basement walls app. 10% Thermal energy losses in a building with no insulation The facade with Rockwool insulation - investment with manifold returns With Rockwool stone wool installation to the certificate of energy performance of building The energy certification of buildings is implemented in most European countries. Energy certificates are issued based on EU Directive 2002/91/EC on the Energy Performance of Buildings. The energy certificate classifies buildings into several classes (A-G), thus showing the energy performance of buildings and energy costs of buildings, which in a certain way also have influences on the market price of a building. The quality of building insulation is the key influence with regard to the energy class in which the building is to be classified. Thus relating to the energy efficiency, stone wool insulation solutions are certainly the most important. The energy balance becomes positive only 5 months after installation. 17 MJ of energy (so-called grey energy) is used in the production and distribution of stone wool. The same amount of energy is saved over a period of 9 months upon the installation of 20 cm of stone wool in the facade. Stone wool on the facade guarantees optimal comfortable indoor environment The stone wool function in the rendered facade system is primarily the thermal insulation, and due to good characteristics in respect of vapour permeability, it ensures without any problem the diffusion of water vapour through external walls without condensation, i.e. possible moisture dry up quickly. With the diffusion of moisture through the external walls, condensation drops appear on the external side of the stonewall layer. When vapour permeable mortar is used, accumulated vapour from that layer dries up freely towards the outside and is not kept locked-up inside the wall structure. The Rockwool stone wool vapour permeability means that the insulation layer enables moisture to dry up towards the outside, thus moisture does not remain in the wall structure and does not dry up on the inside. On the one hand, the vapour permeability property influences the durability of the structure, and it improves the microclimate and comfortable staying in the building.

external wall insulation // Installation methods of thermal insulation on external walls Various ways of installing insulation in respect of its position in the structure thermal insulation of a building internal insulation external insulation Thermal insulation of the external walls from the inside Installation of thermal insulation from the inside of external walls may cause problems; the walls are exposed to considerable thermal differences and loadings that gradually cause the erosion due to weather conditions and damage the walls; moisture coming through the structure always condenses inside the wall or in the wall structure. That may create uncomfortable living conditions (moulds or fungi) and damage the walls resulting from moisture freezing in winter; thermal bridges are unavoidable; ventilated facade ETICS facade panel systems an appropriate vapour barrier must be installed on the internal side of insulation; the heat prevented from storing in the wall; otherwise the wall would return the heat to the room before completely cooling off. Thermal insulation from the inside is less efficient and it is recommended in cases legal requirements do not allow the thermal insulation to be installed from the outside (e.g. monuments protection). Before installing the external wall insulation from the inside, consultation with an expert about installation possibilities is always necessary. Thermal insulation of the external walls from the outside External wall insulation is the provision of insulation onto the external fabric of a building protected by a specialist render. There are many benefits to this method of insulation. Low U Values for walls can be easily achieved using external wall insulation. There are two possibilities of installing the thermal insulation from the outside; ventilated facades, and rendered facade (ETICS). For the ventilated facade, the insulation is fixed on the supporting wall and the finishing layer (glass, stone, iron, wood, etc.) insulation is not mechanically loaded. ETICS is a compact multilayer insulation system where the insulation, has the support function of the finishing (top coat mortar), which are applied directly on the insulation. The thermal insulation of the external walls from the outside is the most efficient way of the building protection against thermal energy loss. An important advantage of this system is the insulation of a building as a whole, which fully prevents the thermal bridges, load, weather related damages of the wall structure and condensation on the structure. It also provides storage of heat in the wall and benefits the wall thermal resistance to creating a more comfortable environment in the building. thermal bridges examples of incorrect insulation of the external walls outside in summer outside in summer outside in summer indoor indoor indoor outside in winter outside in winter outside in winter ventilated thermal insulation system rendered facade (ETICS) flow in the wall without thermal insulation flow in the wall with internal thermal insulation flow in the wall with external thermal insulation

// external wall insulation External thermal insulating composite system (ETICS) with stone wool Approved quality Rockwool products for rendered facade systems were tested according to the European standards. System approvals relate to the performance of the system components as a whole in accordance with ETAG 004 directives for the facade rendered systems, ETICS (External Thermal Insulating Composite System). For these approvals authorized institutions throughout Europe carried out tests on these Rockwool systems. As an additional quality guarantee, in many European countries the associations of producers of similar systems, like WDVS association in Germany, highly recommend Rockwool solutions. System efficiency depends on all its components When choosing the system components, Rockwool recommends only one supplier of adhesives and mortars to ensure the quality. Only the adhesives made by the same producer can achieve guaranteed adhesion as declared in the system attestation. In the system with stone wool, the most important is the vapour permeability of the adhesive and top finishing layer, and coat must guarantee permeability of the system as a whole, and must not retain moisture in the layer between the wall and thermal insulation, or even worse, in the insulation layer. Only attested systems enable appropriate regime of water vapour penetration through the structure, and ensure durability and the quality of the systems. The quality also depends considerably on the installation. While choosing a producer, the consultation with the supplier of adhesive and mortar is recommended, since only experts are acquainted with recommendations regarding the appropriate adhesive preparation. This is very important for the firm coherence of all system components and thus for the durability of the facade as well.

external wall insulation // 9 Rockwool products for rendered facade systems Rendered facade systems with stone wool are the optimal solution for the thermal insulation of the external side cladding of the building, and they are the most appropriate as regards the external aspect of the building. Stone wool protected by the adhesive and finishing mortar provides an individual appearance of the facade. The advantage of rendered facade systems with stone wool is the compact insulation that enables installation of thermal, acoustic and fire protection insulation of facades without thermal bridges. Rockwool range offers slab or lamella slab solutions for the rendered facade systems. Insulation slabs or lamella slabs are bonded on the external side of the wall and a layer of the adhesive and top coat is applied over them. Stone wool is an optimal material for the installation of rendered facades due to its excellent thermal insulating properties, non-combustibility, vapour permeability and acoustic insulation. Installation We recommend that installation is only carried out by Rockwool approved installers. The components of the rendered facade system must always be identical to the components defined in the certificate of the ETICS with stone wool. Cost effective Thermal insulation is one of the main components constituting the total price of the facade system. However, it is very soon paid off through reduced heat loss and heating cost. Thus, when designing the thermal insulation thickness, the recommended insulation thickness should be applied. Stone wool as a completely natural material is somewhat more expensive, but in return it provides durability, mechanical and weather stability, vapour permeability, non-combustibility and ecological sustainability of facades. building before installing the thermal insulation facade dressed in Rockwool insulation finishing facade system Rockwool solutions for rendered facade systems Fasrock, Frontrock max-e The external wall insulation slab is mechanically and adhesive fixed. These slabs have longitudinally oriented fibers and are produced in monolithic or in dual density. They are intended for thin and thick-layer systems. They are recommended for refurbishment and for buildings with high demand for thermal and acoustic insulation. Fasrock L, Fasrock XL The facade lamella may be fixed with the adhesive only. Lamella slabs have vertically oriented fibers, i.e. fibers perpendicular to the wall surface. They are also suitable for slightly curved surfaces.

10 // external wall insulation Recommendations prior to the installation of ETICS Authorized and qualified persons should only install the system. Rockwool stone wool Fasrock, Frontrock max-e slabs or Fasrock L, Fasrock XL lamella slabs can be used with any certified rendered facade system. Weather conditions External wall slabs or lamella slabs should not be installed if the of the air or the wall falls bellow +5 C or rises over +25 C, and if the wind is too strong. By external application of adhesive already installed insulation is protected against possible rain and humidity. Requirements for the underlay - wall All walls should be brushed down to remove spalling brickwork, mortar and loose powdery material. The wall should be dry. Defective areas should be made good to existing surface level. Deviation from the flatness of the underlay should be, upon checking with 4-meter straight strip, up to + - 15 mm. Additional requirements for the installation Before applying the adhesive and installing the insulation slabs, windows, doors and shelves should be mounted. All lights, external faucets, slot supports and the like should be timely and appropriately positioned and always before applying the external adhesive layer, mesh and mortar finishes.

Fixing the insulation The insulation slabs are applied to the wall with the adhesive applied in line along the edge of the slab using the dab fixing method. Adhesive is applied using a trowel. Place the slab on a stone wool package, to gain access to both sides. Apply lines of adhesive along the edge of the slab and six dabs over the slab. Apply enough adhesive to make sure that it firmly adheres along the all edges of the slab and the dabs. 4. applying the adhesive along the edges of the slab 5. applying the dabs over the slab

12 // external wall insulation III Fixing the insulation slabs The Rockwool insulation Fasrock or Frontrock max-e slabs are bonded to each other by being pressed against the slabs already attached. Remember to remove any surplus adhesive that may emerge from the previously attached slabs. The flatness of external insulation surface should be carefully checked, since the facade flatness is indirectly determined in the phase of attaching slabs on the wall. Possible irregularities and minimum deviations can be removed with rough sand paper attached to a float. Make sure that the slabs are laid to bond with each other, and in particular at the corner of the building, window corners and door heads. Windows corners and doors must be insulated using the whole slab (see picture below) to prevent possible cracks and cuts in the corner. All joints between slabs and other elements (window frames, roof, balcony, etc.) should be done by expansion of a moulded part or adequate expansion space that must be filled with appropriated elastic sealing material. 6. removing surplus adhesive 7. detail of an angle bond 8. cutting-off surplus insulation in the corner 9. sanding the minimum deviations incorrect correct correct insulation of a window head correct insulation of a window sill cross-section of an insulated window placing slabs around the window openings IV Fixing with plug anchors Rockwool Fasrock or Frontrock max-e slabs with longitudinal oriented fibers are fixed with facade plug anchors no sooner than 24 hours after they have been attached to the wall. The type and the length of the plug anchors as well as the way of fixing are specified in the technical documentation. All these parameters depend on the type of underlay, the thickness of the thermal insulation, the height of the building and the facade load size. Holes are drilled with a percussion drill, except for opening mesh and perforated bricks and aerated concrete that are drilled with a standard drill. Plastic part of the plug anchor- insert is inserted in the hole, and an iron core is hammered in. The minimum fixing depth that must be in the basic wall is: 5 cm in concrete 8 to 9 cm in perforated brick and aerated concrete example of the correct slab fixing with 8 facade plug anchors over an area of 1 m 2 10. drilling a hole 11. positioning and hammering of the plug anchor Minimum distance from the edge of the wall: > 5 cm (concrete wall) > 10 cm (brick wall).

To prevent facade cracks, stick the strips of reinforcing mesh of at least 30 x 20 cm above the corners of the window and door heads and openings at an angle of 45. Apply the adhesive over the mesh. The adhesive is applied with a toothed float with teeth of 10 x 10 mm. First, apply some adhesive to the slab with the smooth side of the float, and then spread the adhesive over the whole slab surface with the toothed side. The reinforcing plasticized mesh is inserted into the fresh applied adhesive with sufficient overlap (min. 10 cm). The edge of the mesh should be lined with the angle batten. Smooth the corners of the building with an angle float. When the adhesive with the inserted mesh dries out, cut off the surplus mesh along the lower part of the facade. 12. reinforcing a corner 13. applying adhesive with the 14. dragging over the adhesive with 15. preventing danger of cracking smooth side of the float the toothed side of the float 16. inserting reinforcing plasticized mesh 17. reinforcing and smoothing a corner 18. cutting off surplus mesh VI Applying primer and top coat After the adhesive has dried out, apply a finishing layer of mineral or silicate mortar that could be painted in selected colour. Under appropriate weather conditions, the primer may be applied after the adhesive has dried out for at least two days, using a roller for painting. After that, when the primer has dried out (min. 24 hours), the finishing layer of the mineral mortar with the selected granulation is applied. Prepare and apply the finishing mineral layer according to the instructions for use. Application and thickness depend on the selected granulation and the grain of the facade. The facade surface depends on the way of floating the finishing layer. The adhesive for rough finishing layer is applied with a plastic float. Surplus material should be removed with the float at an angle 90 to the surface. The thickness of the layer is usually equal to the average grain size of the mortar. Once the surplus mortar is removed, floating is performed. The finishing layer should be floated while still wet. It is performed with a plastic float moving in a circular motion for a grain texture. Horizontal or vertical direction can give a scraped texture. While drying out and fastening the finishing mineral layer of mortar, the facade must be protected against strong sunlight, rain and wind. At low s and high humidity, the mortar will take longer to dry out. After the finishing mineral mortar is set and dry for a minimum of 7 days, the facade can be painted with silicone paint in the selected shade. Use adhesive strips to achieve a boundary line between two shades of paint. 19. applying primer 20. applying finishing mortar 21. floating in circles 22. applying silicone paint

14 // external wall insulation Installing the rendered facade system with Rockwool Fasrock L or Fasrock XL lamella slabs Stone wool with vertical oriented fibres The application is similar to fixing the rendered facade with Rockwool Fasrock or Frontrock max-e slabs with some exceptions. The difference is in attaching and fixing lamella slabs on the wall surface. All the procedures of applying the base coat, the mesh and finishing layers of mortar on the external side of stone wool are the same for both systems. The following instructions are only the different application procedures. The main difference is that lamella slabs, due to orientation of fibers, which have better mechanical properties, do not need to be fixed mechanically but only to be attached to the wall. Fixing is required only if the facade is higher than 20 m and in case it is required because of the special static safety of the facade system. 5 4 3 2 1 Composition of the ETICS with the lamella slabs 1. base coat (adhesive mortar) 2. lamella Rockwool Fasrock L or Fasrock XL 3. adhesive with inserted plasticized reinforcing mesh 4. masonry primer 5. top coat in required shade I. I Fixing Fasrock L or Fasrock XL lamella slabs The lamella slabs must be clean and without any dust particles. To ensure that lamella slabs adhere perfectly to the wall surface, apply the adhesive on the lamella slab in two steps. 1. Place the lamella slab on the package to have access to both sides. Apply the adhesive to the lamella slab with the smooth edge of the float and spread evenly over the entire surface of the lamella slab. 2. With the toothed edge of the float (12 x 12 mm teeth), make furrows from the adhesive previously applied to the surface of the lamella slab. II Anchor fixing with facade plug anchors (exception) diameter of the part of the facade plug anchor, pressing the lamella slab, should be at least 140 mm The minimum anchoring depth that must be in the basic wall is: 5 cm in concrete 8 to 9 cm in brick and aerated concrete. Rockwool lamella slabs must be anchored with facade plug anchors only when the facade is over 20 m high, or in cases of a weak bearing and undefined underlay (wall). The type and the length of the joints and the way of fixing is specified in the technical documentation for the rendered facade system with the lamella slabs. All these parameters depend on the type of underlay, the thickness of the thermal insulation, the height of the building and the facade load. example of anchoring Fasrock L or Fasrock XL lamella slabs Example of anchoring with 4 facade plug anchors per 1 m 2 and 5 facade plug anchors at the corners, depending on type of underlay. Minimum distance from the corner of the wall: > 5 cm (concrete wall) > 10 cm (brick wall).
