DESIGN DUO MW Sandwich Panel

Key properties of DESIGN DUO MW panels

Excellent thermal insulation and noise reduction

DESIGN DUO MW is a high-quality ALAMENTTI product featuring a non-combustible mineral wool core, precisely enclosed between steel facings, available in Classic, Duo and MicroWave profiles. A wide thickness range from 100 to 250 mm provides:

  • Thermal transmittance: U = 0.36–0.15 W/m²·K
  • Acoustic insulation: up to 32 dB


These parameters effectively reduce heat losses and significantly improve indoor comfort, regardless of external environmental conditions.

 

Fire resistance and durability

Thanks to the combination of steel facings and a mineral wool core, DESIGN DUO MW forms a non-fire-spreading system (NRO), ensuring a high level of fire safety. The protective coating system consists of:

  • External coating: Granite® Ultra Mat 35
  • Internal coating: PE 15 or PE 25


These solutions guarantee UV resistance and enhanced durability, even in highly aggressive environments. The standard corrosion resistance class is
C3, with an option to increase it to C5.

 

Easy installation and modularity

The panel has a modular width of 1000 mm and a length of up to 9 m (for dark colours, a recommended maximum length of 6.5 m). The low surface weight does not overload the supporting structure, and installation using self-drilling fasteners eliminates the need for wet works. Installation is possible year-round.

 

Standing seam aesthetics and wide colour range

DESIGN DUO MW stands out with its elegant appearance achieved through standing seam profiling and a wide range of colours. Available finishing options include:

  • UltraMat colour palette: RAL 7024, 7016, 9005, 8004, 3009, 6020, 8017, 8019
  • Wide RAL colour range and wood-effect finishes on the internal facing
  • Internal profiles: RO (groove), GL (smooth), LA (linear), P25 (micro-trapezoidal), P47 (trapezoidal)

 

Safe logistics

Panels are carefully packed in PE foil and placed on pallets. Transport, storage and on-site installation should be carried out in accordance with the manufacturer’s guidelines provided in the technical instructions available on the website.
