PROJECT OVERVIEW
Seamless Architectural Integration & Uncompromised Safety
When lightning strikes, a structure has microseconds to safely route millions of volts to the earth. For modern architecture, this life-saving engineering must be as seamless as it is robust. This project highlights Enginnovat’s expertise in executing a fully concealed lightning protection system, engineered to strict international safety standards. Our approach ensures uncompromised safety without altering the building’s original aesthetic integrity, making it the preferred method for high-value commercial and residential properties where visual appeal is paramount.
System Capabilities
- International Compliance: Executed to strict BS EN 62305 and NFC 17-102 lightning protection standards.
- Inductive Choke Shield: Non-metallic 32mm PVC conduits safely route high-voltage discharge without dangerous inductive effects.
- Scientific Verification: Precision digital earth testing establishes baseline readings for grounding optimization.
- Architectural Preservation: Walls are precision-chased, plastered, and repainted for a flawless, invisible finish.
Technical Specifications
- System Type: Concealed Down-Conductor
- Conductor Material: 25mm x 3mm Bare Copper Tape
- Conduit Shielding: 32mm Heavy-Duty Non-Metallic PVC
- Wall Chase Depth: 60mm (Dust-Controlled)
- Testing Method: Digital Earth Resistance Verification

Executing a Concealed Lightning Protection System
To maintain the structure’s visual appeal, a concealed lightning protection system requires meticulous planning and execution. Our technicians began by precision-chasing masonry walls to a depth of 60mm using dust-controlled grinders, ensuring a clean working environment.
We then laid a 25mm x 3mm bare copper tape conductor inside heavy-duty 32mm non-metallic PVC conduits. This shielding is critical; it prevents the “inductive choke” effect, a dangerous phenomenon where high-voltage discharge can arc to nearby metallic structures. The entire installation adheres to the rigorous guidelines set by international bodies like the IEC (International Electrotechnical Commission) and British Standards (BS EN 62305).
Finally, the wall was professionally plastered and repainted to perfectly match the building’s original architectural finish, rendering the entire safety system invisible to the naked eye. By safely routing high-voltage surges away from sensitive internals, this structural protection perfectly complements our internal power continuity solutions.
