Internal insulation: two condensed guidelines for beginners

On the way to a reliable and large-scale application of internal insulation, clear and simple guidelines for building practitioners are needed, across all phases of refurbishment planning. Closing this gap was one objective of the “IN2EuroBuild”-project, completed in 2022. As a support in the planning process and for decision-making within the framework of the project, two comprehensive guides for the planning of internal insulation measures were developed. They guide users from the as-is analysis of the building (part one) to the renovation planning of the façade, the selection of suitable insulation systems and the verification and consideration of constructional details (part two). It describes the aspects to be considered during the entire process of planning and implementing an interior insulation measure. Both parts of the guide are aimed at people who have little or no experience in the field of energy efficient refurbishment and interior insulation, but who want to be informed and at least have a say. This group of people can include, for example, building owners, investors or public authority employees, but also architects or engineers who have rarely dealt with interior insulation and therefore do not know the various planning bases and dependencies in detail. The reader should be enabled to assess an issue and select a suitable interior insulation system in the numerous, unproblematic cases in which experts do not need to be consulted.
