HAILSTOP triple-skinned

Highest safety even with strong storms

Due to climate change, strong storms are also increasing more and more in Germany. This creates great hazards for daylight skylights on flat roofs, as large hailstones can particularly cause expensive damage. VELUX Commercial can provide the triple-skinned HAILSTOP dome rooflight to prevent this from happening.

It is equipped with glazing made entirely of polycarbonate. It is therefore highly stable and extremely robust. It is not for nothing that HAILSTOP has been awarded the highest hail resistance class HW5 in the test procedure in the areas of water tightness, mechanics, optics and light transmission. The dome rooflight remains absolutely undamaged even with large hailstones of up to 5cm.

Additional advantages result from the extensive range of accessories which VELUX Commercial provides for its dome rooflights. You can also implement the HAILSTOP as a SHEV device or for daily aeration and ventilation without any problems. Or utilise our sun protection systems for glare-free work. We have the suitable solution for your individual requirements.
