HAILSTOP ROUND dome rooflight double-skinned

The round dome rooflight with maximum hail protection

Protect your daylight elements against storm damage: 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, and light transmission, but also for the optics. For you this means: even with hailstones of up to 5cm, your dome rooflight remains completely undamaged.

With appropriate accessories the dome rooflight can also be utilised as a ventilation opening, as well as for smoke extraction (according to LBO) in case of fire. Also take advantage of our additional accessories 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.
