The quadratic general rotary unitized design of two factors, the temperature and the time were used to study the influence of low-temperature to architectural membrane material. The tensile properties of architectural membrane material were tested after low-temperature treatment, and the mathematical models about breaking strength and elongation at break were built. The two mathematical models proved highly significant by F test, which indicates that the low-temperature environment has a distinctive influence on breaking strength and elongation at break of architectural membrane material. The results are kept to serve as a reference for the rational utilization of architectural membrane material in low-temperature environments.
