Lightning and surge protection are essential in any type of building, whether it is an individual dwelling, a residential building or a critical structure such as a data centre. Lightning strikes are natural phenomena that can release large amounts of energy in a fraction of a second, while both atmospheric discharges and fluctuations in the power grid can cause surges. The consequences of not having a protection system in place or an inadequate one represent a significant risk to people, electronic equipment and the integrity of structures.
