Environmental and climatic conditions within the UK have been one of the key drivers for roof drainage and water management at the roofline position across all types of buildings. From historic buildings through to modern architecture the collection of water from roof level; its efficient distribution to outlet positions and its removal down to ground level drainage has been the subject of many designs and innovations.
To meet these exacting standards, industry has been working with British Standards to ensure that products meet the challenges set upon gutters, outlets and down pipes and all of the other components required to provide a proven system, which is efficient and structurally capable of handling large volumes of water under normal and storm conditions.
The following standards deal specifically with metal based products and systems and the performance of such systems in the built environment. Copies of the standards are obtainable directly from BSi Group.
