Laboratory measurements and on-site measurements: getting closer
Thermal and acoustic insulation made of recycled paper, or cellulose wadding, is used in loose fill or in panels in buildings. A study initiated by a working group of industrial manufacturers with the CSTB explored to what extent the thickness of this loose fill insulation is subject to settling, over time. This is a major challenge in the context of energy transition. The goal is to assess this component's actual contribution to the energy performance of the building envelope.
