RE2020 and bio-based insulation: how to maximize carbon storage in your projects?

Since January 1, 2025, RE2020 thresholds have been tightened: the Ic construction indicator has been reduced from 640 to 530 kg CO₂/m² for single-family homes, a decrease of 17%1. Faced with these new constraints, bio-based insulation is emerging as a strategic lever for complying with carbon limits while ensuring thermal performance. Analysis […]

Guarantees and insurability: why specify cellulose insulation ?

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 benchmark […]

Resistance of cellulose insulation ceilings cellulose insulation what you need to know before insulating your attic

cellulose insulation be blown to a thermal resistance of 12 m²·K/W on a plasterboard ceiling that complies with DTU 25.41. Tests carried out by CERIB for ECIMA have shown that a BA13 ceiling can support a load of approximately 16 kg/m² of cellulose insulation without significant deformation. These results confirm the compatibility of this bio-based insulation with suspended ceilings, provided that the hangers and framework are dimensioned in accordance with technical specifications.

Which insulation materials are most effective against heat waves?

With increasingly hot summers and more frequent heat waves, France is facing a major climate emergency that directly impacts how we design and renovate buildings. Faced with this new reality, the building sector can no longer be content with simply providing comfort in winter. […]

What are the advantages of loose-fill insulation?

There are different types of materials used for thermal insulation: panel insulation (rigid, semi-rigid, and flexible), roll insulation, and loose-fill insulation. This third category is particularly effective at filling even the smallest gaps, thereby limiting thermal bridges. Popular for unused attic spaces, loose-fill insulation can […]
