Resistance to hail

SPF Testing carries out hail tests for all elements of the building shell. Hail stone sizes up to 50 mm, as well as different impact velocities and ice temperatures can be selected.

This covers all available test standard. In particular also the impact resistance tests of building products required by building insurances.

The hazard of hail is known very precisely and different hazard zones are distinguished. The building insurances publish a product register (www.hagelregister.ch) of the hail resistance of different collector types.
