| Downpipe System - Performance Thermal movement
Coefficient of thermal movement is 24.0 x 10-6 per deg C over the range 20°C to 100°C. The design of joints allows for movement, and expansion gaps 2 to 3mm wide should be left between 4m lengths of gutter and downpipe. Compatibility
Zinc chromate primer can be applied to fixing brackets for protection against possible electrolytic action if required (consult Alifabs). Durability
Anticipated life is equal to that of the building in normal atmospheric conditions. References
