Viridian Solar announces that its Clearline Fusion BIPV roofing system has completed the full suite of European fire testing for external spread of flame and has been accredited to have the highest fire resilience in all tests:

Broof (T1), Broof (T2), Broof (T3) and Broof (T4)

The solar panels and roofing kits underwent a battery of different fire-related tests to assess resistance to the spread of flame and roof penetration by a fire that originates externally to the building.

“European fire tests are harmonised into one document, but there is no standard single test. For roofing there are four annexes (T1 to 4) describing four different tests. T1 is for Germany and Netherlands, T2 for Scandinavia, T3 for France and T4 the UK and Eire. Building control regulations in different countries will accept different tests. Clearline fusion is the first roof integrated solar system to be tested against all four tests and it has achieved the top rating ‘Broof’ in all of them,” explains KT Tan, Chief Technical Officer at Viridian Solar.

Stuart Elmes, CEO at Viridian added:

“Our investment in accreditation gives solar installers and housebuilders confidence that Clearline fusion meets building regulations for external spread of flame, wherever they are installing. Because the product is a proprietary system, there are no grey areas and no concerns about whether what is installed is the same as what was accredited. Fire is an area that regulators in many localities are starting to look at very seriously, especially as solar installation volumes increase.”
