| Use advice for data set | Scope: This EPD refers to a specific load-bearing thermal insulation element manufactured by Schöck Bauteile GmbH – Schöck Isokorb® Type KXT15-Combar-CV26-V6-H200-REI120. The compression modules required for Schöck Isokorb® Type KXT are manufactured in the Schöck plant in Landsberg (near Halle, Germany). Final assembly of all required components takes place in the Schöck plant in Baden-Baden. The EPD results for manufacturing Schöck Isokorb® Type KXT15-Combar-CV26-V6-H200-REI120 are applicable for all other load-bearing capacities of this Isokorb® type (Combar 25 to Combar 95) using the factors indicated in section 6. This document is translated from the German Environmental Product Declaration into English. It is based on the German original version EPD-SBG-20160213-IBC1-DE. The verifier has no influence on the quality of the translation. System boundary: Type of EPD: cradle to gate – with options The Environmental Product Declaration refers to the product stage (A1-A3), the end-of-life stage (C4) and recycling stage which is declared in the module governing benefits and loads outside the system boundaries (D). The consumption values associated with landfilling non-recyclable materials are outlined in Module C4. |
| Technical purpose of product or process | Schöck Isokorb® Type KXT-Combar serves as static transfer of bending torques and shear forces, and is used on projecting reinforcement concrete constructions such as balconies, for example. It is arranged linearly in the external thermal insulation level (e.g. composite heat insulation system) in such a way that the thermal flow between the interior and exterior area is minimised locally and thermal bridges reduced. Because of its thermal and statically optimised design, the Isokorb® ensures effective thermal insulation which is indicated by the equivalent thermal conductivity (λeq). |

| General comment on data set | Schöck Isokorb® Type KXT15-Combar-CV26-V6-H200-REI120 is a load-bearing thermal insulation element for thermal separation of reinforcement concrete elements projecting from the inner slab construction. It comprises a thermal insulation layer 120 mm in thickness made of polystyrene rigid foam (Neopor®) as well as an effective static framework system of glassfibre-reinforced plastic tension bars (Combar), welded steel bars (shear bars) and a system of compression modules made of ultra-high-strength concrete (high thermal performance (HTE) compact compression modules). The forces are transferred to the respective adjacent components via bond stress and pressure. Schöck Isokorb® Type KXT is available in several load-bearing capacities which are aligned towards the required load capacities. The number of tension bars, shear bars and HTE compression modules depends on the load-bearing capacity. The exact fittings displayed by Schöck Isokorb® Type KXT15-Combar-CV26-V6-H200-REI120 are indicated in the table in section 2.3. The declared product is supplied in a fire-resistant version with fire-resistant slabs attached on the top and bottom in the factory, and displays a fire-resistance duration of 120 minutes (REI120). The EPD results for manufacturing Schöck Isokorb® Type KXT15-Combar-CV26-V6-H200-REI120 are applicable to all Isokorb® types with higher load-bearing capacity. The products with the respective load-bearing capacities (KXT15-Combar to KXT95-Combar) have identical components which vary depending on their mass (number of bars and compression modules). The manufacturing process for the products with load-bearing capacities (KXT15-Combar to KXT95-Combar) is the same. |

| Technology description including background system | Processing raw materials The bars made of glassfibre-reinforced plastic (Combar) are produced by Fiberline in Denmark from where they are transported to the Landsberg (Halle) plant before being cut to size and then transported to the Baden-Baden plant as preliminary materials. The base material for the welded reinforcement steel-stainless steel compounds in the Schöck Isokorb® is wound as "metal wire" on coils, delivered and decoiled in special plants, aligned and cut to the required length or manufactured straight from the coil using recognised and certified welding processes on special automatic welding machines within in-house production in Baden-Baden. The shear bars are bent on in-house bending machines and bundled using retaining clips. The HTE compression modules made of high-performance concrete are cast in prefabricated plastic moulds which serve as integrated formwork in the plant in Landsberg in accordance with the mixtures stored at Deutsches Institut für Bautechnik. End assembly The materials required for final assembly of the various Schöck Isokorb® models are produced in-house and procured from selected suppliers. The various Schöck Isokorb® models are assembled on special manufacturing lines according to type and depending on specific customer requests. During final assembly in the plant in Baden-Baden, the requisite components (tension and shear bars, compression modules, plastic rails, foam parts and fire-resistant slabs) are bonded in accordance with the applicable manufacturing drawing and the corresponding quality guidelines using mechanical bonding technology as well as a special hot-melt adhesive. Declared unit: This Declaration refers to one metre of specific load-bearing thermal insulation elements manufactured by Schöck Bauteile GmbH – Schöck Isokorb® Type KXT15-Combar-CV26-V6-H200-REI120. |
