To manage the rainwater demand the installer will determine the required rainwater capacity of gutters and downpipes. This capacity calculation takes into account the maximum rain intensity, roof or façade surface and location. The installer will eventually estimate the dimensions of the rainwater drainage system and will decide which components are applicable.
The rainwater is collected by the roof gutters and guided through downpipes into a sewer, another disposal point or collector. The zinc gutters and down pipes are produced in many variations and NedZink has a large product range with accessories for numerous application.
