Sandwich panel SPA E Patina
Sandwich panel SPA E Patina is available in thicknesses 150 - 230 mm.
With precise and Ruukki specific manufacturing tolerances, and factory-fitted seals on the panel joints, the Ruukki® Energy panel structure with its seams forms a very airtight solution. Together with Ruukki Airtightness package it’s possible to achieve excellent airtightness to the entire building. This can decrease energy costs and CO2 emissions up to 30%.

Using Ruukki's solutions you can receive more credits in LEED and BREEAM certification systems.
With the filling consisting of non-combustible and environmentally friendly hard mineral wool, this sandwich panel ensures excellent fire resistance. Properly milled core increases air-tightness and contributes to outstanding sound insulation.
Ruukki® Patina panel is made of natural and untreated Cor-Ten® steel. The unique joint structure of the panel prevents corrosion at the joints (patent pending). The new, innovative panel is also maintenance free since it repairs scratches over time itself.
Application:
- External walls (standard fix)
The method for joining Cor-Ten® steel-based sandwich panels, preventing corrosion formation in the joint, is patented.

Design tools

Traypan® software for designing sandwich panels
With TrayPan®, you can design metal faced sandwich panels made by Ruukki. A panel structure can be designed as a single- or multi-span construction. You can easily give, with a few parameters, both suction and pressure loads caused by the wind. The application also calculates the necessary fasteners.
