A new CSTB guide

The CSTB (Scientific and Technical Center for Building) has published "Choosing and Implementing Bio-based Insulation," a practical guide for building professionals looking to incorporate high-performance and sustainable materials into their projects. Written by Hafiane El Cherkaoui, an evaluation and expertise engineer at the public institution, this document clearly illustrates the most commonly used techniques, highlighting best practices and warning of common mistakes to avoid. Covering the main bio-based materials for thermal insulation, the guide details several implementation techniques that comply with industry standards, NF DTU (French Unified Technical Documents), CSTB e-Notebooks, CPT (Technical Specifications), Technical Approvals, and other Technical Application Documents. It applies to rooms with low and medium humidity levels, excluding environments with high humidity.

With the implementation of the RE2020 regulation, the focus is on the energy performance and carbon footprint of buildings. The author emphasizes the importance of integrating low-carbon materials and adopting appropriate installation practices to preserve the thermal performance and durability of bio-based insulation. Accessible and instructive, *Choosing and Implementing Bio-Based Insulation* is a reference tool for roofers, architects, and specifiers who want to master the use of these insulation materials while respecting regulatory requirements and best practices in the sector. Available from the CSTB online store.
