Insulation works of attics
NF DTU 45.10 "Insulation works of attics with factory made rollers or board of mineral wool" is now published and available since June 2020. It replaces CPT 3560_V2. On the other hand, in May 2020, the CSTB published e-Cahier 3815, "Guide to the provisions and calculation rules relating to water vapor sealing systems for roofs", which supersedes CPT 3647 concerning the calculation method for water vapor condensation risk in roofs.
