Hail resistance classes
The risk of hail has increased considerably in recent years. This trend is also illustrated by various damage statistics. In general, more than one third of building damage caused by natural events is attributable to hail. As a result, the majority of our photovoltaic modules also offer added value here and are therefore equipped with hail resistance class 4 from a front glass thickness of 3mm. Hail of this size is „golf ball-sized“ and has a diameter of 40mm and an impact speed of 99km/h.
DIBt approval for SONNENGLÄSER
Our SONNENGLÄSER have a general building authority approval from the German Institute for Building Technology (DIBt). Thanks to the approval, these are considered regulated construction products (analogous to classic VSG glass) and no longer require individual approval for each project.
