ERLUS | Highly hail-resistant
Huge hailstones pelt the roof at breakneck speeds. Tiles crack, the roof starts to leak and the rain gets in. Anyone who has already witnessed this destructive force of nature will be sure to want a roof that is stable. What a good thing ERLUS has a range of hail-proof roof tiles!
Frequency and intensity of hailstorms are on the increase
Current statistics show that hailstorms on a destructive scale have been occurring more frequently over the last few decades. According to a study by MunichRe in 2019, severe hailstorms are on the rise in Europe, and the damage potential has likewise increased. It was found that hailstones, some of them the size of tennis balls, caused vast damage through much of Germany in 2013: smashed roof tiles which let the rainwater run into buildings. Solar plants destroyed, house fronts pocked with holes, and battered cars. In some regions, 90 per cent of the buildings were affected. The total damage amounted to around EUR 4 billion, with EUR 3.1. billion concerning buildings. Link to the study
Hailstorms due to climate change
Climate researchers fear that extreme hailstorms will occur more and more often in Germany, Austria and Switzerland. Rising temperatures caused by climate change provide ideal conditions for thunderstorms to brew.
Hail protection with better construction materials
How can you protect yourself against damage of this kind in future? By installing high-quality products that are certified hail-resistant (up to HRC 4/5). Switzerland already took the route towards prevention back in 2010: the hail register (www.hagelregister.ch) was introduced by a combination of property owners, under-writing associations and the Swiss Society of Engineers and Architects. There is a similar register in Austria as well (www.hagelregister.at). ERLUS finds the hail register very convincing, and has had its products tested, certified and registered. Link to hail register

Invest in a sturdy roof – it’s worth it
With these building materials you’ll be on the safe side and protected in emergencies.
With these building materials you’ll be on the safe side and protected in emergencies. The test results are published in the hail register. It’s not just insurance providers that can access it – house builders and planners can get information there too. The database is divided into hail impact resistance classes and provides information on which product can withstand hail. Sound construction materials not only provide protection in emergencies but can also be rewarded by insurance companies. Anyone who builds using products that are certified hail-proof can reckon with cheaper premiums. www.hagelregister.info
The ERLUS roof tile range – excellent results in the hail impact resistance test
ERLUS subjected its roof tile range to a durability test at the Institute of Fire Protection Technology and Safety Research (IBS) in Linz, Austria. The result: the entire clay roof tile range achieves at least hail impact resistance class (HIRC) 4. That’s equivalent to a hailstorm with hailstones of up to 4 cm in diameter. The Ergoldsbacher E 58 PLUS, the first clay roof tile in Europe to achieve HIRC 5 in the hail impact resistance test back in 2015, is especially robust. The ALU-SYSTEM from the range of ERLUS brand accessories and the Ergoldsbacher Kirchenbiber (Church beaver) also achieved this class. The Ergoldsbacher Handschlagbiber (Hand cut Plain), with a body thickness of 21 mm, even withstood firing with ice balls of 6 cm in diameter, and was certified with HIRC 5+.
The excellent result of the hail resistance test confirms the tremendous stability of the ERLUS roof tile range. It’s one of the best types of roofing when it comes to hail, and meets high safety standards. In view of the storm development prognosis, this is a valuable quality criterion for sustainable, future-oriented construction.

This is how hail impact resistance is classified and tested
The Institute of Fire Protection Technology and Safety Research (IBS) in Linz, Austria, confirms the tremendous stability of the ERLUS range.
The Institute of Fire Protection Technology and Safety Research (IBS) in Linz, Austria, tested the hail resistance of our range of roof tiles with a hail simulator. In the test, standard ice balls of 70 mm in diameter are fired at the surface. The weight, diameter and impact velocity of the lab-created ice balls are the decisive factors for the load on the roof tiles in a hailstorm.
