Sammanfattning
A study was carried out on insulation materials for residential buildings, considering their main properties, both technical and environmental. A wall model that is thermally insulated with four different insulation materials was used as reference. With the wall variants designed, a comparison of the environmental impacts and of the insulation materials required to meet the thermal insulation requirements established in the regulations was carried out. For this, Life Cycle Analysis was used as a tool to assess the environmental impacts and the EDIP and ELU methods to calculate the global environmental performance. The results showed that the material with the best behaviour in terms of environmental impact is the insulation based on cellulose fibre, while aerogel blankets are still not recommended according to the results, despite its better technical conditions, showing the worst results in almost all the impact categories analyzed. The performing of the most used materials in construction in Europe today (rockwool and glasswool) is in between of the other materials, being lower in both cases relative to aerogel and higher than that associated with the use of solutions based on the cellulose fibre. Glasswool shows an environmental performance worse than rockwool because of its much greater impact in terms of depletion of abiotic resources due to elements. In this category is the material that gets the worst result.
