PIR rigid foam

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.

PIR is made from the raw materials MDI and polyol. In contrast to PUR foams, excess MDI is present in the manufacture of PIR, which is why it partially reacts with itself. The result is PIR, a very highly networked plastic with ring-like structures. The raw materials MDI and polyol dominate the LCA. In module C1, a manual dismantling (no loads) is assumed, collecting losses are neglected. The transport in module C2 to the recycling plant takes place with a truck (50km). Module C3 takes into account the grinding and thermal treatment (combustion) of the material. When calculating combustion emissions and credits, the specific calorific value of each material and the material composition are taken into account. In module D credits for the substitution of electricity (German electricity mix) and thermal energy (from natural gas) are given.

PIR high-density foams are used as insulation e.g. of industrial floors and roof structures with high loads.
