Weather proofing to rely on

Testing every step of the way – that's the only way to guarantee performance.
Rigorous proofing in the in-house laboratory of all components ensures perfect design and, finally, independent authorisation from the Institute of Window Technology, Rosenheim.

Sunplan achieves Group 'B' and more importantly Group 'C' Certificates to DIN 18055. A rating not currently
achieved by other systems.

How our weather tests are carried out

Classification to DIN 18055 – Performance Group C

• Tested system SL 70, SL 50, SL 66, SL 67, SL 68

A 3 panel system is subjected to air pressure of 600 Pascals with water sprays in a laboratory. This is equivalent to a 120 m.p.h. hurricane force wind with driving rain. At the same time the system is continuously reversed to flex the components backwards and forwards.

The system is then opened and closed 10,000 times and the test repeated.

There is NO leakage of water up to 600 Pascals and less than 1/4 of the permitted air leakage. Test standards determine the maximum permissible air leak rate. A single drop of water passing through the system would mean that the system would fail the test.

Classification to DIN 18055 – Performance Group B

• Tested system SL 35, SL 45, SL 65

As above at 300 Pascals, equivalent to a 60 m.p.h. wind with driving rain.

There is NO leakage of water up to 300 Pascals and less than the permitted
air leakage.

New EuroNorm Tests

As part of our programme of continual product testing many of our systems are now available tested to the latest EuroNorm standards

Component Tests

• Rollers tested in 20,000 operation without any visible sign of wear and tear.

• 180° turn handles pressure checked up to 1,000 Pascals.
