Dry underfloor heating DRYFLOOR MAGNUM

The MAGNUM DryFloor system enables dry-construction underfloor heating where build height is limited or subfloors are less load‑bearing (e.g. timber floors). The system is composed of profiled EPS insulation panels on which aluminium Omega heat distribution profiles are positioned to accommodate the heating tube.

Key features

• System height: 25 mm (dry construction)
• Aluminium Omega profiles spread heat across the floor surface; thermal conductivity: 80 W/mK
• Fast thermal response compared with traditional screed systems
• Recommended tube diameter when used with the insulation panels: 14 mm
• Approx. 8 aluminium profiles required per m² (rule of thumb)
• Subfloor must be stable, level and clean prior to installation
