Protan has developed a unique system with factory engineered backing strips, which enable non-penetrating mechanical attachment of the membrane. The system provides greater resistance to wind uplift because fixings are distributed over the entire membrane area. Using the Secret Fix System is often cost efficient, because it requires less welding and reduced quantity of fasteners.
The Secret Fix System is the best solution:
On vertical applications
In heavy wind areas
When the steel deck is running parallel to the side lap of the sheets
When quick installation is required
Secret Fix System can also be combined with other Protan systems to optimise the design.
