To prevent dirt settling on glazing, we recommend to mount the glass glazing in the angle of 5° and to use dome version for PC glazing.
Because of snow overload (there is a danger of glazing collapsing and leaking) of flat glass and flat polycarbonate (PC) glazing, it is necessary to regularly clean snow from the skydome surface.
Follow the instructions for skydome snow load measurements.
