Sandwich Panels
Good Cladding@
Insulated composite panels for providing thermal and acoustic insulation effects for roofs and exterior walls, allowing for the rail-less mounting of PV modules
- Effective cover width: 430mm
- Length: 1m-12m (customizable)
- Sandwich panel thickness: 20mm
- Metal sheet thickness: 0.3mm-0.7mm
- Core material: Rigid polyurethane (PUR/PU), mineral wool, glass wool
- Metal sheet material: Galvalume steel sheet, titanium zinc sheet, Al-Mg-Mn alloy sheet
PU sandwich panels are part of a new generation of wall and roof solutions that combine thermal insulation, sound absorption, and decorative appeal in one product. They are designed with interlocking ribs that improve waterproofing and drainage, while also making the panels stronger and more visually refined. A built-in interface allows solar modules to be mounted directly with special clips, eliminating the need for drilling or extra rails and significantly lowering the investment costs of rooftop photovoltaic systems.
PU sandwich panels can be used on both roofs and exterior walls of industrial and residential buildings. They are also suitable for schools, hospitals, shopping centers, office complexes, and the renovation of older facilities where energy efficiency and durability are priorities.

- Sandwich panels provide effective thermal insulation and noise reduction, which helps to maintain stable indoor temperatures and a quieter environment.
- A ribbed surface profile improves water drainage and waterproofing performance, while also giving the roof a more refined appearance.
- Solar modules can be attached directly onto the sandwich panels; it´s only necessary to use special clamps, eliminating the need for rails or drilling and reducing installation costs.
- Designed to resist strong winds, seismic activity, and heavy snow, providing reliable protection in different climates.
- Durable surface coatings make the panels resistant to weathering and corrosion, keeping maintenance requirements low.
- High-quality PVDF finishes help preserve both color and appearance over time, even in harsh outdoor environments.
- The lightweight composite structure reduces the need for complex sub-layers, making installation faster and easier.
