HOW OUR WEATHER TESTS ARE CARRIED OUT

• Tested system ASL70, ASL60, ASL66, ASL67

Classification to DIN 18055 –
Performance Group C
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.

• Tested system ASL35, ASL45, ASL65

Classification to DIN 18055 –
Performance Group B
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.

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.

Only trust laboratory tested and
certified systems

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.

Only Glassplan achieves
Group 'B' and more
importantly Group 'C'
Certificates to DIN 18055,
a feat not currently
achieved by others.

Only supplier with test report “Stress Group C”.
