Cd Reef V4 Cstb 2021 May 2026

Artificial reefs mitigate coastal erosion, enhance marine habitats, and reduce wave energy. CSTB’s CD Reef (Coral Defense Reef) series has evolved since 2012.

Version 4 (2021) focuses on:

With RE2020 emphasizing energy efficiency, the 2021 evaluation added a mandatory declaration of thermal resistance. For CD Reef V4, the R-value per 10mm thickness is approximately 0.025 m²K/W. While minimal, this contributes to lower thermal bridging in floating floor systems. You might find older documentation for "CD Reef
