Highest possible hail protection for your light dome

The ever increasing number of storms always poses a high risk for skylights on industrial flat roofs. Hail can particularly quickly lead to considerable damage in the glazing. We have developed the JET-HAILSTOP light dome here at JET so that you do not have to worry about hail anymore.

These comprise glazing completely made of polycarbonate which makes them extremely stable and robust. This has also been proven by the test methods which we have applied to our light dome. With a clear result: The highest hail resistance class of HW5 was utilised to classify the areas for both the water tightness and mechanical properties as well as the optics and light transmission. This means that the light dome can remain completely undamaged even with hailstones up to 5cm.

But these are by no means all the advantages of JET-HAILSTOP. It is also compatible with a wide range of accessories and can – with the corresponding opener accessories – be utilised for both ventilation and also smoke exhaust. Whether in new construction or refurbishment: the JET-HAILSTOP is always a good solution for your flat roof.
