Resistance to Wind-Driven Rain of Roof Coverings with Discontinuously Laid Small Elements
At Lucideon, we have extensive expertise, knowledge and experience in the field of roofing. As a UKAS accredited testing laboratory (No. 0013), we are able to offer testing and consultancy services that encompass all aspects of rain, wind and weathering testing.
The resistance to wind-driven rain of roof coverings with discontinuously laid small elements testing program is performed against the PD CEN/TR 15601:2012 standard and specified for:
- Lower roof pitches - as roof pitches become smaller, it is necessary to ensure that the roofing system can cope with rainfall and wind exposure
- Weather-tightness of roofing joints - for commercial roofing systems, negative wind pressure causes a different type of stress and movements in the joints that can be verified with this testing regime
- Severe exposure - the different tests and criteria enable the behaviour of the roofing system to be predicted under severe exposure conditions.
It consists of 4 different testing categorizations/criteria with the following outcomes:
- Combinations A+C - these minimum requirements enable the system to be used in medium exposure areas
- Combinations B+D - will enable the system to be used in severe exposure areas
- Full combination package - will enable the system to be used in all conditions.
We can adapt the testing regime and equipment to different climate zones and variable roof pitches:
- Northern Europe
- Central Europe
- Sothern Europe
- Coastal zones
- Wind speed: 2 to 25 m/s
- Rainfall: 6 to 415 mm/h
- Roof pitch: 15 to 45 degrees.
- Roofing tile systems
- Conservatory roofing
- Velux windows
- Commercial roofing.
This unique test places differential pressure caused by wind movement over the roof; under real-world conditions, this is usually the cause of failure.
Once the roofing system has satisfactorily passed the testing regime, you will be assured that the performance has been validated to the highest testing standard, under the toughest weather conditions.
