HAILSTOP ROUND dome rooflight double-skinned

The round dome rooflight with highest possible hail protection

Protect yourself against storm damage to your daylight elements: with the round version of the tried and tested HAILSTOP. This guarantees maximum safety due to the very robust polycarbonate glazing, even in the event of extreme hail storms.

We have had this tested and received certification for the HAILSTOP ROUND with the highest possible hail resistance class. It was awarded the HW5 class not only in terms of water tightness, mechanics, light transmission but also for the optics. For you this means: even with hailstones of up to 5 cm, your dome rooflight remains completely undamaged.

The dome rooflight can also be utilised as a ventilation opening with appropriate accessories aswell as for smoke extraction (according to LBO) in case of fire. Also utilise our additional accessories in order to adapt your dome rooflight even more individually to your completely personal needs. The HAILSTOP ROUND is possible for applications in new buildings and refurbishment projects.
