| Use advice for data set | Scope: This validated Declaration entitles the holder to bear the symbol of the Institut Bauen und Umwelt e.V. It exclusively applies for products produced in Europe and for a period of five years from the date of issue. This EPD may be used by FEICA members and their members provided it has been proven that the respective product can be represented by this EPD. For this purpose a guideline is available at the FEICA secretariat. The members of FEICA are listed on its website. System boundary: Modules A1-A3, A4, A5 and D are taken into consideration in the LCA: A1 Production of preliminary products A2 Transport to plant A3 Production incl. provision of energy, production of packaging as well as auxiliaries and consumables, waste treatment) A4 Transport to site A5 Installation (disposal of packaging & installation losses and emissions during installation) D Credits from incineration of packaging materials & installation losses and recycling the metal container The declaration is therefore from "cradle to gate - with options". |
| Technical purpose of product or process | Module 1: Façade sealants Silicone-based construction sealants are used for the elastic sealing of joints. The areas of application for façade sealants include expansion joints (movement joints) and/or connection joints already existing in exterior walls and on window and door frames (in- cluding the inside section). All these sealants fulfill key functions of the building. Module 2: Sealants for glazing Silicone-based construction sealants are used for the elastic sealing of joints which may be subject to movement. Sealants for glazing are used in the following areas: Glass to glass Glass to frame Glass to porous substrates Module 3: Sanitary sealants The areas of application for silicone-based sanitary sealants are joints in sanitary areas and kitchens. Joints sealed using sanitary sealants comprise connection joints between sanitary furnishings and the wall, connection joints between the floor and wall or movement joints across surfaces, for example. |

| General comment on data set | Silicone-based construction sealant, filled or unfilled, transparent or pigmented. Silicone-based construction sealants are manufac-tured from reactive siloxane and so-called silicone oil, sometimes using fillers, extenders, colour pigments, cross-linkers, bonding agents and catalysts. They permanently and elastically seal joints planned for the building. Silicone-based construction sealants fulfill key functions. Ingress of moisture into the structure via the joints is prevented by joint sealants. By using silicone-based sealants the fitness for use of the building and the service life are decisively ex-tended. The product displaying the highest environmental impacts was used as a representative product for calculating the Life Cycle Assessment results (worst case-approach). |

| Technology description including background system | Silicone-based sealants are generally manufactured by mixing the ingredients and then filling them into the delivery containers. The quality of the products and safe handling thereof is ensured by the corresponding regulations such as /EN ISO 9001:2008-12/ and the provisions outlined in the relevant regulations such as the Industrial Safety Regulation and Federal Pollution Control Act. Technical data: Module 1: Façade sealants The minimum requirements on water and airtightness as per Table ZA.1 of /EN 15651-1:2012/ apply: see table Module 2: Sealants for glazing The minimum requirements on water and airtightness as per Table ZA.1 of /EN 15651- 2:2012/ apply: see table Module 3: Sanitary sealants The minimum requirements on water and airtightness as per Table ZA.1 of /EN 15651-3:2012/ apply: see table Declared unit: This EPD refers to the declared unit of 1 kg silicone-based construction sealant with a density of 1 - 1.5 kg/l in the mixing ratio required for processing the components in accordance with the PCR Part B for Building sealants. The results of the Life Cycle Assessment provided in this declaration have been calculated from the product with the highest environmental impact (worst-case scenario). With the information about the consumption per running meter together with width and depth of the joint, the results can be calculated into a declared unit of l/m. |
