Name
Precast Concrete Sandwich Walls
Technical purpose of product or process Precast concrete sandwich walls are used in construction of different building types - starting from single-story and high rise residential buildings to extensive administrative and public buildings and complexes. The wide range of complexity and design of sandwich walls produced by SKONTO PREFAB allows to decrease construction time of one object significantly. Precast concrete sandwich walls (SW) of different design in wide range of complexity are included in this EPD: 2. Sandwich wall with brick cladding Composition: Concrete, reinforced steel, insulation, plastic, additives and for design products - brick tiles are as well. Sandwich walls are composed of several concrete layers with installed heat insulation between them, which is very important from the perspective of energy saving.

General comment on data set Product specific data is from 2018, the database data are from 2011 – 2018 i.e. no data is older than 10 years. Database used: Ecoinvent 3.5. The LCA software used is SimaPro 9.0 The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production inhouse is allocated equally among all products through mass balance allocation. Effects of primary production of recycled materials allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis All major raw materials and all the essential energy is included. The production process for raw materials and energy flows that have very small amounts (<1%) are not included. This cut-off rule does not apply for hazardous materials and substances.
