How hail resistant are your products?

Sustainable and future-proof constructing is essential and may only be guaranteed if producers start to rethink. Classify your products and give your customers the chance and the security of optimum building and renovation experiences!

The following bases may be applied to the tests:

  • VKF test specifications
    Vereinigung Kantonaler Feuerversicherungen - Index of test specifications
  • OENORM EN 13583
    Flexible sheets for waterproofing - Bitumen, plastic and rubber sheets for roof waterproofing - Determination of hail resistance
  • FM 4473
    Specification test standard for impact resistance testing of rigid roofing materials by impacting with freezer ice balls

A single product data sheet is enough for us to be able to prepare an individual offer.

Test report

For each of the component functions set down in the construction-specific test regulations, the test report establishes whether a building component can be considered intact or damaged with regard to a certain criterion (e.g. water resistance, appearance, mechanics, light shielding and transmission). This report will serve as the basis for entry in the public hail register.

Test types


You can have your products tested and classified. Subsequently, you will receive a test report with accompanying photo documentation.

Indicative test

With this test you will learn how resistant your products are. Such findings are useful in the further development and improvement of your products. You will get a transcript with remarks and accompanying photo documentation.

Why classify?

The test is performed in accordance with a standardised procedure based on Swiss specifications (VKF specifications) to ensure a uniform and reproducible classification of top-quality. Each test specimen is subject to specific, real-world testing requirements. Every measuring process is recorded electronically and documented in a test report. Decisive factors in hailstorms for the loads of components are the size, impact velocity and impact angle of the hail. The manufacturer can use the test result and product classification for promotion purposes when referring to the hail register.


Standardized hailstones produced in a laboratory with a diameter of up to 70mm are accelerated with compressed air at an impact velocity of up to 220 km/h to hit a target with a hail impact simulator. The velocities correspond to naturally occurring impact velocities of hailstones of similar sizes.
