Mineral wool (flat roof insulation)

This data set has been modeled according to the European Standard EN 15804+A2 for Sustainable Building. Results are depicted in modules that allow the structured expression of results over the entire life cycle.

Dataset describes Mineral wool and Glass fiber. Mineral wool is made of sedimentary or igneous rocks (mainly basalt) and various recycled materials. The material is melted in the melting furnaces at 1400-1500 ° C and passed through rapidly rotating rollers. Binding agent is added. The binder then hardens in continuously operated tunnel kilns. For the glass wool a pure primary glass is melted in a furnace at about 1400 ° C. This process consumes power. The molten glass is centrifuged in a perforated rotating drum. The warm airflow evaporates the water and the fibers solidify. The raw fibers are guided on conveyor belts through a tunnel kiln. The binder cures at about 200 ° C. The fibres are then cut to required size and packed. System boundary is the finished product at the factory gate. Transportation from the factory to the site is not included in the dataset and must be taken into account separately when analyzing the complete life cycle. For different applications, typical compositions and densities were modeled. A following distinguished applications were defined: flat roof, facade, floor, roof and interior. In the disposal phase, a manual dismantling (no loads) is assumed in module C1. The transport in module C2 to the landfill site takes place with a truck (50km). In C3, if relevant, a packaging with PE foil is taken into account (for example, for mineral fiber products. 0.0125 kg foil per kg of discarded material). In module C4 the average landfill emissions corresponding to the product (reference country Germany) are shown. The use of landfill gas is not taken into account.

This product can be used in construction.
