External lightning protection for residential buildings
External lightning protection forms a safe tent over the residential building. It intercepts the lightning with an air-termination system, safely dissipates it via down conductors and distributes the lightning current into the ground via the earthing system. This prevents flashovers and possible fires and protects people.
Good to know: A complete lightning protection system consists of external and internal lightning protection. In this way, you provide comprehensive protection and avoid gaps in safety.
The right path to external lightning protection system for residential buildings
Do you plan, install or test lightning protection systems for residential buildings? Then observe the normative specifications of the IEC 62305-3 lightning protection standard for the protection of structures and persons. An external lightning protection system is built on several pillars:
- Air-termination system on the roof
- Equivalent separation distance between the air-termination system and the systems to be protected on the roof
- Down-conductor systems on or in the wall
- Earthing system with appropriate termination points
- Lightning equipotential bonding
The installation of an external lightning protection system depends on various information relating to the building, such as building dimensions, roof superstructures, etc. It must therefore be customised to suit the local conditions.
We offer a comprehensive range of products from air-termination systems to down conductors and earth entries, including the necessary holders and clamps.

The aim of an external lightning protection system is to protect buildings from direct lightning strikes and fire or from the effects of lightning current.
Lightning strikes are the main source of surges and jeopardise buildings and installations even if they are protected by a lightning protection system.
