Sandwich panel SP2B X-PIR

Sandwich panel SP2B X-PIR is available in thicknesses 40 - 110 mm.

It is a perfect solution for most buildings and structures, combining high quality with very good technical properties. The panel's excellent quality ensures very good fire resistance properties, thus increasing fire safety of buildings.  

The core of this sandwich panel is made of rigid, HCFC-free, self-extinguishing and sustainable polyisocyanurate foam (PIR). Its excellent thermal insulation properties enable the decrease of panel thickness which transfers directly to lower transportation and assembly costs, as well as significant savings of building's life cycle costs.

To make both architectural and structural design work easier, with accurate product information in 3D form, we offer a selection of CAD / BIM -objects for Autodesk Revit and ArchiCAD.


Software 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.
