burckhardt’s glide sliding windows have passed the hurricane test in the US which is one of the most challenging tests regarding statics and tightness with water.
The window system undergoes various quality tests. Suction and pressure, which occurs with buildings in extreme storm zones, is for example simulated in the testing process. The window is here tested regarding air inlet and water intrusion. In order to stimulate hurricane occurrences, the window frames and glass are also watered intensively and bombarded with wooden posts.
