Benchmark Watertight Testing of 3 Façade Membranes Euroclass A1 and A2
Euroclass A1 membranes have been developed for non-combustibility, but their water protection is inadequate for many buildings as the outer coating has been reduced to achieve the A1 fire rating.
Our new video compares the watertightness of two A1 façade membranes with an A2 membrane, Stamisol Safe One. It explains the test rigs and procedures for the W1 test (EN 1928) and W2 test (EN 13111) and shows, how the 3 façade membranes are performing.
Only one of them is approved W1: Stamisol Safe One, Award Winner at CIBSE Facade Award 2022 / Product of the Year.
