| Abstract | This paper presents experimental findings from accelerated aging tests, simulating long-term performance indicators, on SVR and compares them with the similar observations made on traditional 6-mil poly (i.e. polyethylene) vapor and air barrier. Elevated temperature and ultra violet (UV) light were the two primary environmental agents used to accelerate the aging process. The performance of the vapor barrier was assessed from water vapor permeance, air permeance and tensile strength properties at various stages of aging. The results from these tests indicate that water vapor permeance, air permeance and mechanical properties of SVR do change due to accelerated aging. In aged SVR material, compared to the original specimens, the RH dependency of the water vapor permeance at higher RH levels appears to be less evident. However, overall performance of SVR, while compared to 6-mil poly, does not exhibit significant concerns about its accelerated weathering performance or serviceability. |
