| Use advice for data set | Scope: The EPD applies for all member companies of the Bundesverband der Gipsindustrie e.V. in accordance with the current list of members on www.gips.de and for products manufactured in Germany. The LCA considers specific information supplied by the manufacturers and suppliers of components exclusively for the cradle-to-gate production stage. This document is translated from the German Environmental Product Declaration into English. It is based on the German original version EPD-BVG-20140070-IAG1-DE. The verifier has no influence on the quality of the translation. System boundary: The EPD refers to the production phase in accordance with DIN EN 15804, i.e. it comprises the manufacturing steps from the cradle to the factory gate. Modules A1-A3 include the production of raw materials and transport thereof, the provision of energy and the manufacturing processes required for the production of all components for the dry screed product made from gypsum fibreboard. |
| Technical purpose of product or process | Dry screeds made from gypsum fibreboards are used for floors in new buildings and in the refurbishment of residential and office buildings as well as in public buildings. Dry screeds are applied on a separation or insulation layer on even, load-bearing sub-surfaces. Uneven sub-surfaces are levelled prior to installation. The elements are pasted and screwed if necessary in the joint area. Dry screeds can be installed for all standard floor coverings and are suitable for underfloor heating systems. . |
