UV stability with joints up to 30 mm wide exposing no more than 30% of the surface to 13859-1/2, permanent. Guidance for specification option: UV resistance without final coating: Laboratory ageing test data cannot reproduce unforeseeable causes of the product's degradation, or consider the stresses to which it will be subjected during its service life. To ensure its integrity, as a precautionary measure, exposure to weather during construction should be limited to a maximum of 12 weeks. According to DTU 31.2 P1-2 (France) 5000 hours of ageing equates to a maximum exposure of 6 months during the construction phase. UV stability with joints up to 30 mm wide exposing no more than 30% of the surface: The membrane is not intended as a final waterproof layer for roofs. |
