| Technical purpose of product or process | A half-sandwich wall panel, combining a robust concrete layer and a layer of Kooltherm insulation, usually used as an exterior wall, offers a durable and energy-efficient solution for modern construction. They are manufactured in different thicknesses depending on the desired function. Theese walls are casted on horizontal mold tables with one side that is counter-molded, down in form and on side with mounted insulation, up in form. The concrete provides structural strength and resilience, while the Kooltherm delivers excellent thermal insulation. This prefabricated unit streamlines the building process, ensuring quick installation and airtight performance, making it ideal for a variety of architectural applications where efficiency and longevity are paramount. Concrete walls are 100% recyclable and enable fast, cost-effective and rational progress in the construction project. |
| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |

| Technology description including background system | The declared element is a 1-tonne insulated concrete wall with a total thickness of 350 mm and a surface area of 15 m². It consists of concrete of strength class C45/55 with a water-cement ratio (w/c) of 0.50, combined with Kooltherm insulation. The declared tonne includes an average reinforcement of 21.5 kg per tonne and an average amount of cast-in materials of 2.65 kg per tonne. The declared unit also applies to a wide range of dimensions, assuming average reinforcement and cast-in material quantities. The cement used is Heidelberg Materials Bascement Plus Slite CEM II. See NEPD-11488-11382 for reference. Concrete strength C45/55. Exposure classes up to XC4-XF1. Life length class up to L100 (100 years). More technical data and information about load capacitys for the different wall dimensions is available at Heidelberg Materials Precast Contiga's concrete factory in Norrtälje. |
