Eco-Sandwich Wall Panel System, the Sustainable Prefabricated Wall Panel System Made of Recycled Aggregates

This paper presents the life cycle analysis of the ECO-SANDWICH wall system, an innovative ventilated prefabricated concrete wall panel with integrated mineral wool insulation allowing very low energy design and retrofit of buildings. The purpose of this research and development of the ECO-SANDWICH is to encourage the reuse and recycling of construction and demolition waste as well as to reduce utilization of natural resources. The substitution of conventional thermal insulation materials by Ecose® based mineral wool produced using innovative and sustainable technology leads to additional environmental benefits through the reduction of embodied energy, embodied carbon and production of by-product wastes.
