As a specifier, you have a ten-year liability for each project. Thermal insulation defects can render a building unfit for its intended purpose and lead to costly disputes. In light of these challenges, ACERMI certification for cellulose insulation essential legal and technical assurance.
ACERMI: the essential reference for securing your specifications
Third-party certification and independent audits
Founded in 1984, ACERMI (Association for the Certification of Insulation Materials) guarantees the quality and performance of insulation materials for professionals. This certification requires biannual audits and initial testing by independent bodies such as CSTB and LNE. For cellulose insulation, it rigorously validates thermal conductivity (λ), thermal resistance (R), and also the ISOLE profile, which assesses mechanical properties, water behavior, and vapor permeability.
Guaranteed, long-lasting thermal performance
ACERMI certification attests that thermal resistance is achieved under specific installation conditions (thickness, number of bags per 100 m²). Certified insulation materials have thermal conductivities of 0.038 to 0.040 W/(m.K), enabling R-values of 6 to 9 m².K/W to be achieved depending on the application. These values are continuously monitored to ensure compliance with RE2020 requirements.
Insurability and compliance: protect your projects and your liability
Requirements of DO insurers and ten-year guarantees
Thermal insulation defects are covered by the ten-year warranty when they render the structure unfit for its intended purpose. Case law confirms that insulation defects leading to excessive energy consumption engage the builder's ten-year liability. Building damage insurers require certified materials: specifying ACERMI-certified insulation facilitates the insurability of your projects and limits the risk of claims being denied in the event of damage.
RE2020 regulatory compliance and CCTP
RE2020, mandatory since January 2022, promotes low-carbon bio-based materials. cellulose insulation perfectly meets these requirements thanks to its verified FDES (Environmental and Health Declaration Forms). Technical specifications increasingly require certification to justify thermal performance: ACERMI is therefore becoming a mandatory requirement to ensure the administrative and technical compliance of your projects.
Technical arguments for confident prescribing
Full traceability and verified FDES data sheets
Each ACERMI-certified product has a certificate that can be viewed on the website www.acermi.com, ensuring complete traceability. Collective or individual FDES (Environmental Product Declarations) accompany certified insulation materials, facilitating the life cycle assessment (LCA) calculations required by RE2020. This comprehensive technical documentation provides security for your thermal studies and building permit applications.
Feedback and reduced accident rates
ACERMI-certified products benefit from decades of feedback from the French market. Manufacturers such as Igloo France offer insulation certified by CSTB Technical Appraisals, significantly reducing the risk of damage. This documented track record reassures project owners and facilitates the acceptance of your specifications.
Secure prescription = successful project
Prescribing cellulose insulation means choosing legal certainty, regulatory compliance, and technical performance. You protect your professional liability while guaranteeing your customers sustainable and high-performance solutions.
