RDEK 40 Roof Deck Panel

The FALK RDEK 40 is a top choice for light, low-slope roofing, excelling in long-term performance, particularly for projects needing strong diaphragm shear support. It's an upgrade from conventional B-decking, integrating high-quality polyisocyanurate insulation between two steel layers to meet demanding design needs. Combined with self-adhered or fully adhered single-ply thermoplastic membranes, it becomes a key component in durable roofing systems.

  • Long-term performance for low-slope roofing
  • Compatible for roof slopes 1.5:12 and less
  • Ready for TPO or PVC application
  • Suitable for phased installation without weather concerns
  • Replaces traditional B-Deck solutions

Versatile Slope Compatibility

This system works well for slopes ranging from a slight 0.25:12 to a more noticeable 1.5:12. The FALK RDEK 40 panels come ready for TPO or PVC application, with a primed and coated exterior. Available in thicknesses from 3 to 6 inches, these panels offer a blend of robustness and visual appeal. They're designed to attach directly to purlins or joists, ensuring a neat interior look.

Seamless Protection and Efficiency

Offering seamless protection and efficiency, the FALK RDEK 40 ensures watertightness right after installation. It has water-tight tongue and groove joints and a pre-installed foam gasket to prevent vapor and water penetration. This feature speeds up other construction stages, leading to quicker, more cost-effective building completion. Its water-tight design also allows for phased installation without concerns.
