Use advice for data set	Cradle-to-grave; A1-A3, A4-A5, B1-B7, C1-C4 and D. Modules B1-B7 are not relevant as the product need neither maintenance, repair, replacement, refurbishment nor use energy or water.
Technical purpose of product or process	Knauf Skena SKP LOWR is a construction product used as a runner, U-profile, and has a PE-strip that is glued to the web. Primarily used for drywall construction of interior plasterboard walls and ceilings with acoustic properties. The steel profile is made of zinc-coated steel coils. The steel is 100% recycled and with a production based on an electric arc furnace (EAF). The product is recyclable and available in different dimensions. The steel grade used for this product is S250GD+Z140. The nominal steel thickness is 0,47 mm and the PE- strip has thickness 4 mm.

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.

¹This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
²The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
