Lightning protection innovation for thatched roofs

Unsightly freestanding masts, which are on average 20-25 metres tall, have been used for the protection of thatched roofed structures against lightning strikes for many years.

DEHN Africa introduces DEHNsure. A complete, isolated lightning protection system with DEHN approved, tested and proven components.

DEHN has cover for professionally approved installations of DEHN products, which is extended to a customer that has such a system protecting their thatched roof structures in a better looking and safer way!

What if lightning protection masts could be aesthetically pleasing and effective?

The DEHN HVI lightning mast is mounted directly on top of the ridge capping, making it both more effective and more aesthetically pleasing compared to conventional free-standing masts.

The mechanical support of the lightning mast is critical to ensure stability during lightning and extreme weather conditions. The supporting tube is fastened by means of specially designed mounting brackets, enabling the insulated conductors to run easily down the rafters / beams.
