The Siding Architectural Sandwich Panel is the most used on buildings that is searching for a carefully aesthetic finish: offices, shopping centers, industrial warehouses, school buildings, hotels… We have built and sold Architectural Panels, smooth, and with bridges for all type of constructions with spectacular results for our clients.

The Flat or architectural siding sandwich panel differs from the rest of the panels because it incorporates a completely smooth outer steel sheet, for a refined and modern image, with a thickness greater than usual to provide more resistance to the whole.   Furthermore, at Panel Sandwich Group we also manufacture it in various polyurethane core thicknesses and adjust the thermoacoustic insulation.  This panel for siding can be placed both vertically and horizontally and by increasing the thickness of the metal sheet we will avoid the water effect (which is very common in panels of other manufacturers).  This problem comes when eliminating the outline of the sheets and unattractive bubbles are formed due to the exposure of the sun light.

Our architectural siding sandwich panel offers high thermal insulation from 35mm to 100mm thick and its installation is very simple, thanks to a system to the machined that hides the screw and protects the union from water leaks. In Sandwich Panel Group, we also incorporate the staple used in other panels that increase the strength and carrying capacity of the architectural panel making it unique at a very competitive price.

  • The invention relates to a tongue-and-groove connection system with conceals the fasteners used in assembly.
  • Smooth plate with a thickness greater than usual to avoid the water effect and increase even more resistance.
  • WE can manufacture it in various colors like silver metallic, in black Dexter, red tile, blue lake.

Example specific case of load table or resistance for Architectual Sandwich Panel siding sandwich panel in 40mm thickness with 2 or more points of support.  For sheet steel 0,4/0,4.  The values are those that comply at minimum, having point loads that support more than shown.  For more information or generic resistance tables according to the panel configuration, you can be requested to our sales department.


The architectural sandwich panel is composed of two plates of galvanized and pre-coated steel that protect a high density injected polyurethane insulating core: 40 Kg/m3.  The main feature of the smooth siding sandwich panel is that the interior sheet is manufactured completely smooth, in this way we create an integrated image and a careful aesthetic look.  Losing the characteristic profiling of the usual siding panels what we do at Panel Sandwich Group is to make this smooth sheet with thickness greater than usual (up to 0.8 mm) and shorten the lengths to 7 or 8 meters, thus we avoid the effect Waters so harmful in any construction work.

The Sandwich Panel Architectural Siding adapts to each work to offer the best result in all kinds of situation.  The high customization we offer in our panels is divided: thickness and design.  As for the thickness of the insulation core we have several options between 35 and 80 mm getting the proper protection in each case.  On the other hand, if we focus on the design, you can opt for a wide variety of colors on request such as Terracotta Red 3009, White Pyrenees 9010, Black Dextar 9011, Green Navarra 6005 among many more.

The installation of the Architectural Sandwich Panel is quick and simple, since it has a system similar to tongue and groove that favors the union between the panels, avoiding leaks, while hiding the screw to offer a spectacular finish. The panels are screwed onto rails or U-shaped rives for a rugged and durable construction. In addition, we have optimized them to be able to mount them both vertically and horizontally. Always guaranteeing exceptional aesthetic levels that no other material can achieve

The architectural Sandwich Panel for Siding has a fire performance qualification as C S3 D0 / B S2 D0 by incorporating rigid polyurethane foam in its insulating core. This qualification is the result of official tests in accordance with current Spain legislation, yielding values that equal or exceed the minimum parameters established in the European framework.

Sandwich Panel Installation process

Accessories and endings


Protects the external area of the facade at the 90º meeting point between two sandwich panels for a spectacular finish. Available in white and various sizes.


It is anchored at the 90° joint between two panels. This will prevent leaks, unwanted movements and a good aesthetic finish from the inside.


Metal omegas are the perfect solution to act as a support or secondary structure for panels or simple sheet metal. Among the many advantages are weight resistance and reduced assembly costs.


The U-shaped finial serves as a rail or guide for insulated wall panels. Screwed on the floor or under the roof, it provides a support point on which the sandwich panel is fixed to offer maximum protection. It is manufactured in the same color as the wall panel, generally Pyrenean white.


Screw specially optimized for installing Panel Sandwich Group wood panels. Ask us about the specific fasteners depending on the project time and we will recommend the best option.


We provide the screws for self-drilling metal structure to fix the Insulated Wall Sandwich Panel. Any work or reform should pay attention to the small details, so we will guarantee a result and total effectiveness.
