Life Cycle Assessment of Rock Wool Board and EPS Board

Abstract:

Although outer wall thermal insulation technology is an effective measure for building energy-saving, the production of thermal insulation materials causes serious impacts on environment. In the present investigation the resource, energy consumption and environmental emission of the two kinds of thermal insulation materials were analyzed, from the acquisition of raw materials to production process based on Life Cycle Assessment (LCA). The result show that life cycle energy consumption of rock wool board is 415MJ per functional unit, proximately twice of EPS board’s (220MJ). Overall, environmental impact indicators caused by rock wool board is more serious than EPS.
