When to Use Osma StormLine

StormLine is the right choice when RoundLine and DeepLine do not have enough capacity for your property. Common applications include large detached houses, bungalows with wide roof spans, properties in high rainfall areas of the UK, extensions that significantly increase the roof area draining into one run, and light commercial buildings such as offices and small retail units.

For even larger commercial and industrial buildings, consider Osma SuperLine 125mm or Osma RoofLine 150mm.

Osma StormLine vs DeepLine

Both StormLine and DeepLine are high capacity systems that use the same 68mm downpipe. StormLine offers a higher flow rate than DeepLine, making it suitable for properties where DeepLine is borderline on capacity. If your roof area comfortably fits within DeepLine's limits, DeepLine is the more cost effective option. If you are close to the limit or in a high rainfall area, StormLine provides the extra margin of safety.
