Abstract: The flexible putty is a supporting material for exterior wall thermal insulation system. This article introduced the raw material, the basic formula, the preparation technology and the application method of flexible putty. The functional filler was industrial waste fly ash cenospheres rather than the expensive hollow glass beads. This flexible putty showed low dry density and high efficient in preserving heat. The layer thereof played an important role in avoiding crack of protective layer and decorative finish, enhancing thermal insulation effectiveness and improving energy efficiency, providing a good prospect in the future.
