2 Be on the safe side. We take fire protection seriously. The fully enclosed HIT-HP and HIT-SP ensure compliance with the highest fire safety requirements in accordance with REI 0 according to EN 0 as well as classification F0-AB according to DIN 0 in compliance with ETA-/0 and numerous other approvals. This is made possible by the special shape of the insulation in combination with the use of high-quality non-flammable mineral wool, Building Material Class A and Euro Class A, respectively. Circumferential fire barrier as an efficient fire barrier in the insulation layer with full balcony integration Additional fire protection measures, e.g. circumferential fire barrier or additional lintel fire protection, must be provided to increase the resistance of external thermal insulation composite system using expanded polystyrene (EPS). The HIT-HP and HIT-SP units work as a fire barrier around the area of balconies and porches and ensure the necessary fire-retardancy of ETIC-Systems. This reduces additional costs for fire prevention. Installation detail: HIT-HP and HIT-SP units as part of fire barrier

12 HALFEN HIT INSULATED CONNECTION HIGH & SUPERIOR PERFORMANCE Basics on Load Bearing Capacity Load bearing behaviour of the HIT-HP MV and the HIT-SP MV Cutting edge technology made by HALFEN As a world first, the HALFEN Insulated cantilever slab connections HIT-HP and HIT-SP feature the innovative and patented structural C S B Compression Shear Bearing system. The load bearing compression bearings and stainless steel shear bars previously used, have been replaced by the innovative technology of using compression shear bearings made of ultra-high strength fibre-reinforced mortar. The C S B act as a compression shear zone and transfer the compressive and shear forces in the HIT-HP and HIT-SP insulating elements. Integrated safety concept For the first time, the complete verification and design concept for balcony connections has been incorporated into a National Approval. The ETA-/0 and the National Approvals include verification of the moment/shear force interaction of the C S B as well as verification against concrete edge failure to ensure load transfer into adjacent components. This includes all respective verifications for slab connection regarding the force transmission. Consequently, time-consuming additional verifications such as the limitation of the concrete compressive strut are no longer necessary. The structural engineer is provided with maximum planning reliability. In addition to the technical approval you will of course find the LGA Würzburg type test available for download on the HALFEN website. The type test includes the transferable bending moments M Rd and shear forces V Rd of normal load ranges for concrete strength classes C0/, C/0 and C0/ as well as for the concrete covers for tension bars with c v = 0 mm, mm and 0 mm. The load bearing capacities of selected elements are illustrated in more detail on pages to 0 for HIT-HP/SP MV and on pages to 0 for HIT-HP/SP MD. The component resistances of the elements with a width of.00 m, 0.0 m and 0. m are each stated per running metre. This allows easy selection and planning reliability for any connector length. With different concrete strength classes on the balcony and the main slab, the lower concrete strength is decisive when selecting load range capacity level. The structural behaviour of HIT Elements If the maximum vertical force bearing capacity V Rd, is not fully exploited, the C S B technology provides the opportunity to increase the moment bearing capacity so that it exceeds M Rd,. M Rd, is the maximum moment bearing capacity with the corresponding vertical force bearing capacity V Rd,. This load bearing behaviour is considered in the HIT software. This software selects the optimum load range of the HIT elements. HALFEN software is available at V V Rd, V Rd, M Ed V Ed 0. precise verification Simplified calculation using linear interpolation M Rd, M Rd, Diagram: moment/shear force interaction at the cantilever slab connection With C S B technology shear forces of up to 0 kn per metre can be transferred safely and in accordance with the National Approval (applies to slab thickness 0 mm). To ensure these high load bearing capacities are kept within the application range for cantilever slab connection, the following ratio of the external force variables must be observed: M Ed V Ed 0. M The load bearing capacity of the elements is characterized by a moment/shear force interaction curve (see diagram).

Integrated safety concept HALFEN s integrated safety concept includes all necessary verifications including shear force analysis for concrete compressive struts according to DIN 0- / EN -- (EC) for design of HALFEN HIT Insulated connections. The shear force verification above may become decisive, especially in minimal slab thicknesses. Consequently, the steel load bearing capacities for the proposed insulated connections can only be partially applied.. m units with cv = mm HIT unit with cv = 0 mm HIT units with cv = mm () Corner Filler. m Including the shear force verification of the concrete compressive strut in the load bearing capacity allows the structural engineer to make a statically and economically reasonable selection of elements, without requiring additional verifications for the insulated connections. This helps to ensure that HALFEN HIT Insulated connections are selected and used in compliance with the approval. The HALFEN HIT Insulated connection integrated safety concept does not include the verification of any adjoining structural elements.

100 HALFEN HIT INSULATED CONNECTION Building Physics Thermal insulation Structural thermal bridges such as balconies may lead to moisture problems resulting from lower temperatures on internal surfaces. Moreover, thermal bridges normally cause additional loss of heat. Consequently, correct planning using thermally insulated balcony slab connections: prevent condensation and mould growth by fulfilling the minimum thermal insulation requirements according to DIN 0- reduce the transmission heat losses in the area of the connections Prevention of condensation and mould growth by fulfilling the minimum thermal insulation requirements according to DIN 0- Depending on the temperature, the air can retain different amounts of moisture. With a rise in air temperature, the amount of storable moisture increases. In a room, the air is constantly moving (room air flow). The water content in a defined flowing air volume remains nearly constant. However, the temperature of the air changes when the air flows along colder external components. The storage capacity of the air decreases as the air cools down, resulting in an increase in relative humidity. Condensation always occurs when the relative humidity reaches 00 %. Assuming a room temperature of 0 C and a relative humidity of 0 % condensation would occur when the air cools down to approx. C (see dew point diagram on the right). If, under the given conditions, the temperature at the inner surface of an adjacent component, for instance the wall or the ceiling, is C or colder, then condensation will form on this surface. Correct application of HALFEN HIT Insulated connections prevents the surface of the wall/ceiling from falling below the dew point and therefore prevents condensation. An increased relative humidity of approx. 0 % above the surface of the component promotes mould growth. In a standard scenario with an indoor temperature of 0 C and a relative humidity of 0 %, cooling down the air to approximately C raises the relative humidity to 0 %. dew point temperature Fig.: Dew point diagram ambient room temperature ambient room temperature ambient room temperature relative (air) humidity HALFEN HIT Insulated connections prevent cooling of the adjacent components at the inside of the balcony below the critical temperatures for condensation and mould growth. The criterion to prevent mould growth is the temperature factor f Rsi. It is defined as the ratio of the lowest surface temperature minus outside temperature to the total temperature difference (inside temperature minus outside temperature). f Rsi θ si θ i θ e θ e DIN 0- stipulates that the temperature factor f Rsi must be higher than 0. for all component connections. According to the National Approvals Z-.-, Z-.-0 and Z-.- the minimum thermal insulation requirement in accordance with DIN 0- has already been proved and applies to the complete HALFEN HIT Insulated connections load range. 00

101 HALFEN HIT INSULATED CONNECTION Building Physics Reduction of transmission losses The Energy Saving Regulation (EnEV) specifies that the primary energy demand required to heat a building must be limited. To calculate this energy demand, thermal bridges through concrete balcony slabs must also be taken into account. Monolithic balcony systems without thermal separation have the same effect as cooling fins due to their geometry and therefore they cause substantial heat losses. Thermal bridges can be calculated in three different ways: Method : An increase of all thermal transmission coefficients by U WB = 0.0 W/(m²K) for the entire heat transmitting outer surface without any further analysis of the thermal bridges. Method : When consistently adhering to the regulations for energetically efficient component connections according to DIN 0, supplementary sheet, the effect of the thermal bridge is taken into account with the increase of the thermal transmission coefficient for the total heat transmitting surface area by U WB = 0.0 W/(m²K). Method : By a detailed verification of the specific transmission loss of the thermal bridges according to DIN V 0- or DIN V or by the deter mination of an individual additional value for thermal bridges. HALFEN HIT Insulated connections provide the engineer with every opportunity to determine the effect of thermal bridges by using all verification options mentioned above. Method is used to calculate the highest transmission losses. Engineers who don t consider the structural design of thermal bridges are disciplined by the regulations of the Energy Saving Regulation (EnEV) with high additional transmission losses. The simplified verification method (Method ) where U WB = 0.0 W/(m²K) is applied can be used because HALFEN HIT Insulated connections are classified in DIN 0, supplementary sheet, according to National Approval Z-.-, Z-.-0 and Z-.-. The respective verification has also been proven for the HALFEN HIT Insulated connections with the highest reinforcement content. Method : In most cases even when conforming to the specifications stipulated in DIN 0, the calculated specific transmission loss H T (resulting from standard cross-sections and thermal bridges) is still so high that the max. thermal ceiling set by the EnEV is not easy to maintain. Planners have to deal with this problem when they have to meet predefined criteria. In these cases it is necessary to determine the exact transmission losses of all thermal bridges in a detailed analysis. For structural component linear connections the linear thermal transmission coefficients (ψ-value) are defined by set standards. Some building products manufacturers specify a eq -value for the insulation capacity of thermal separation elements. eq is the equivalent thermal conductivity of a replacement cross-section of inhomogeneous building products without any metallic penetration such as for a special insulation element at the base of the masonry. In this case, the ψ-value for the detailed analysis of the thermal bridges can be determined with the eq -value by a two-dimensional calculation of the thermal bridges by the engineer without having to model a geometrically complex insulation element at the base of masonry. This method is only applicable to a limited extent for structural components with metallic like penetrations as found in balcony slab connection as uniform standards for basic or boundary conditions calculation for equivalent thermal conductivity value have not been defined. The thermal values for HALFEN Insulated connection types HIT-HP MV / HIT-SP MV and HIT-HP ZV / HIT-SP ZV are included in the European Approval ETA-/0 and National Approval Z-.- and Z-.-. Standard specification for non-residential buildings The DIN V specifications regulates the calculation of annual primary energy demand of non-residential buildings, thermal bridges are calculated analogously, i.e. they can also be alternatively calculated using method, or to determine specific heat transmission loss H T and the annual energy demand. 0

113 HALFEN HIT INSULATED CONNECTION Building Physics Soundproofing according to DIN 0 Soundproofing Requirements With balconies and access balconies, vibration is transferred into the main structure of the building and distributed into adjacent rooms as airborne sound. DIN 0 specifies the maximum level of the airborne sound pressure level L n,w which penetrates the adjacent units of the building and which is measured with a standardised tapping machine. For access balconies in multi-storey buildings with residential and business units, the current version of DIN 0 published in specifies as follows: req. L n,w = db (req. TSM = 0 db) The impact sound transmission from the balcony into the adjacent units can be significantly reduced by using thermally separated balcony connections. In DIN 0 there is no requirement defining the necessary sound-proofing insulation for balconies. This more than 0-year-old norm is out of date and does not represent current technology. Under special boundary conditions the standard versions of HALFEN HIT Insulated connections can fulfil the sound insulation requirements for access balconies. The sound insulation properties of different elements were examined in independent on-site measurement and in measurements done in the MFPA Braunschweig laboratory.

114 HALFEN HIT INSULATED CONNECTION Building Physics Fire protection according to EN 0 and DIN 0 All significant requirements concerning fire protection are laid down in the respective Building Regulations of the Federal States or in the relevant Master Building Regulations. The components in close contact to the HALFEN Insulated connections HIT-HP or HIT-SP must also meet the requirements of the respective fire resistance class according to EN 0-0 or DIN 0- including DIN 0- in order to fully exploit the fire protection classification of the connection. The standard versions of the connecting units HIT-HP and HIT-SP are classified in class REI 0 according to EN 0-0 as well as in class F 0-AB according to DIN 0 in compliance with the European Technichal Approval ETA-/0 and the National Approvals Z-.-, Z-.-0 and Z-.-. This is possible due to the special shape of the insulating body in combination with the use of high-quality nonflammable mineral wool, Building Material Class A and Euro Class A, respectively. The structure prevents flashover on the element sides as the insulating wool encloses the load bearing elements (CSB, shear bars and tension bars) from all sides. R E I Meaning of the abbreviation REI: The structural safety of the connection is ensured for the specified duration. The propective effect of the connection is ensured for the specified duration. The thermal insulating property of the connection is ensured for the specified duration. 0 The functions above mentioned are ensured for 0 minutes of fire exposure in compliance with the standard time/temperature curve. HIT-HP MV unit Thermometer View into the fire test chamber during the HIT-HP MV fire-test after 0 minutes of exposure The compliance with requirements concerning fire protection of any adjoining structural elements must be verified by the engineer. Advantages The advantages of the new connection element in comparison to the elements used in conventional construction methods with polystyrene and fire boards are obvious: no confusion of the standard and F 0 versions selecting a fire-resistant element doesn t compromise heat insulation efficiency. no damage to the load bearing elements caused by flashover on the sides as the fire-resistant insulating wool encloses the load bearing elements from all sides protection against weathering
