Chiffres clés de la certification, évolution du nombre de certificats, surveillance et faits marquants.
Faced with ever-warmer summers and longer heatwaves, designing high-performance buildings that are adapted to hot weather is now a major issue.
Last year resulted in a sound, stable performance, which is a gratifying outcome given the health and economic crisis and supply chain issues for some components, such as polystyrene and cardboard, which are used in the manufacture of insulation systems.
The transition from RT2012 to RE2020 resulted in a reassessment of the thermal performance objectives of products.
Inertia (the ability of a material to store and then release heat) of course contributes to the energy performance of a building envelope.
Thanks to compaction tests performed in the laboratory, ACERMI gives users of insulation products a guarantee of thermal resistance measurements.
2021, un bilan stable malgré le contexte sanitaire et la pénurie de certains matériaux
Joint interview with the presidents of ACERMI, Étienne Crépon, president of the CSTB, and Thomas Grenon, president of the National Metrology and Test Laboratory (LNE), on the French energy recovery plan and ACERMI's contribution.
To be certified, the performance parameters of an insulation product must be tested and verified. From production plant sampling to writing the test report, the product goes through various tests to assess its performance.
The feedback from experience and experimentation over many years through Technical Appraisals is making it possible for thermal insulation systems in unused roof spaces (with loose-fill mineral wool and cellulose) and converted attics (with mineral wool in panels or rolls) to become commonplace.
