DESIGN DUO sandwich panels

DESIGN DUO – a “3-in-1” sandwich panel that insulates, protects and accelerates your investment
The DESIGN DUO sandwich panel is a complete solution for walls and roofs, combining effective thermal insulation, modern aesthetics and fast installation for a wide range of industrial and commercial applications.

3-in-1 sandwich panel: insulation, cladding and façade in one system
The DESIGN DUO façade panel is a ready-made sandwich panel that replaces traditional layers such as insulation, sheathing and façade finishes. This solution significantly reduces construction time and lowers costs related to additional materials and labor. Panels with a modular width of 1000 mm and lengths of up to 12.5 m are installed directly onto steel or timber structures, eliminating the need for mortars, adhesives and wet construction works.

Applications of DESIGN DUO sandwich panels

  • Thermal refurbishment of industrial halls, retail pavilions, cold stores and warehouses
  • Modular construction – containers and prefabricated buildings
  • New frame structures – showrooms, service stations and industrial canopies
  • Roofs and façades where energy efficiency and modern aesthetics are key priorities

DESIGN DUO thermal insulation – lower costs and higher efficiency
arious insulation core options (white EPS, graphite EPS or mineral wool) allow the panel to be precisely tailored to the building’s energy performance requirements. A thermal transmittance value as low as U = 0.12 W/m²K means:

  • reduced heating and cooling costs
  • compliance with current WT 2021 technical regulations
  • more usable internal space

Sandwich panel façade – durability and modern appearance
The external steel facing with Granite® Deep Mat 25 coating provides a modern matt finish in UltraMat colours while offering high resistance to corrosion, UV radiation and mechanical damage. Interior finishes are available in RAL colours as well as wood-effect options.

Fast dry installation – lower investment costs
DESIGN DUO panels are installed using self-drilling screws, without plastering, additional insulation layers or separate façade systems. This results in savings in:

  • construction time
  • labor costs
  • additional materials

System safety and durability

  • NRO classification – non-fire spreading
  • Standard corrosion resistance up to class C3, with optional C5 for aggressive environments

Products

DESIGN EPS F DUO thermal insulation panel

Sandwich panel with graphite EPS insulation core (λ = 0.031), offering improved thermal conductivity compared to standard EPS. At the same thickness range (100–250 mm), it achieves a lower U-value while maintaining low panel weight. Standing seam profiling provides a modern architectural appearance for roofs and façades, while extended panel lengths significantly reduce installation time.…

Design DUO EPS G Sandwich Panels

Sandwich panel with graphite EPS insulation core (λ = 0.031), providing superior thermal performance compared to conventional EPS insulation. Within the same thickness range (100–250 mm), it delivers an improved U-value while retaining a lightweight structure. Standing seam profiling enhances the modern look of roofs and façades, and longer panel lengths help accelerate project completion.…
