Our roof sandwich five frets panel, is characterized for being one of the most resistant panel in the market.  Panel Sandwich Group, has make great improvements over the year on this particular panel.  This type of panel is ideal for roofing since is compose by 2 extra ridges making a total of 5 frets on it´s upper top sheet that gives a solid reinforcement on the Surface.  It´s outline and ridges top surface creates a mechanical resistance against wind, and snow, and also can support extra weight when placing solar panels on it´s top sheet.  It´s overall weight resistance it could be messured by weight per m² in extrem conditions. The 5 frets Sandwich Panel is usually used when we have few support points or we want to sabe structture since it allows to spans the infractured support points further apart than the other options without lising its mechanical porperties.

The 5-fret Sandwich Panel, differs from others similar traditional ridge sheet panel, due to having a thermal insulation in between, made out of polyurethane foam, of which comes in different thickness.  The core thicknesses could be obtain in 30, and 60 mm, stander, but in case your development  poryect required more thickness on the foam, this could be manufactures on thickness of 80 and 100 mm.

In addition, we offer the option to manufacture the 5-frets Sandwich Panel in various color to choose from.  The most common is Pyrenean White RAL 1006, however, if you need a specific or corporate color for your roof we also have other designs such as: Tile Red RAL 7001, Navarra Green RAL 3000, Lake Blue RAL 4000, Silver Metallic RAL 9006, Bidasoa Cream Real 2002.

Our 5-frets Sandwich Panel is different from the rest of traditional panels because it has slightly higher and wider frets, which gives it up to 14% more resistance than others in the market.  Although the insulation and durability are similar, the strength and safety margins are greater because it is specifically designed to withstand more weight per m2 withut increasing the costo f the producto, just by making better use of the width of the sheet and outlining it where there is the greatest gain.

It includes a hermetic seal between it´s overlap joints ends that makes it wátertight and condensation proof, when essanblying.  This hermetic seal on it´s joint, is key to avoid problmes and to ensure that the most resistant roof panel on the market fulfils its function: to insulate us from wáter and exreme temparatures, increasing the load resistance of the panel.

The weight of the panel correspond to sheet thickness of 0.5/0.5 mm. The insulation of the 5 Frets Sandwich panel is manufactured in 4 different standard thinkness base on polyurethane that makes a great thermal insulation capacity. However, under request and conditions, it is possible to manufacture the foam thickness in 80 and 100 mm.

Example of specific case of load or resistance table for the 5 frets Sandwich Panel, in 50mm with 2 or more support points. With sheet thickness 0.5/0.5 mm. The values of the table dependo n the thickness of the polyurethane and the thickness of the sheet used. The values are common in the installation of the Sandwich Panel on a roof, when they are moving through the roof during the assembly of the same. For more information or specific resistance tables according to the configuration of the panel, you can request it to your sales representative.


The 5 frets sandwich roofing panel is composed of two sheets of top quality, and laquared on galvanized steel, the outline protect the insulating core that is injected of polyurethane material, base on 40 kg / m³. This composition gives the panel excellent qualities: excellent thermal insulation that allows the regulation of internal and external temparatures, resistance due to it´s ridges and great quality of the steel, protects against humidity and leaks, for a long durability, without the need for major maintance cost.

The main difference between the 5 frets sandwich panel and others sndwich panels, is its strong outline: as it has two more ridges than the 3 frets panel, which can support greater loads without forcing the exterior sheets, but always contemplating the distances of the metal, wood or crete structure between the panel´s support points.

The 5 fret sandwich panel that we manufacure in our facilities adapts to all kinds of designs and needs. You can consult at any time with our sales representatives and they will recommend the best fit for your project. For example, you can choose between various thicknesses of polyurathane foam that will adjust the thermal insulation to the máximum needs. We have thicknesses between 30 and 50 mm, which are our most common for all types of contruction. However, on request we can manufacture higher thicknesses, up to 100 mm reserved for specific projects.

The assembly of the 5 frets sandwich roofing panel is extremely simple: the panels overlap each other thanks to a system of wings and are fastened to the structure iwth self-drilling screws that incorpórate a special cappellotti or washer iwth neoprene gasket that prevents wáter filtration. Thanks to its assemble process and compasition, a panel with 5 frets has been obtained with a total resistance above any other. It is especially used for large industrial works and reduces labor costs to the máximum.

Like all or panles, the 5 frets sandwich panels has been subjected to the tests required by current Spanish regulations on reaction to fire, with results that exeed nationa and Europena requierments. The fire performance of these panels is classified as C S3 D0 due to their polyurehtae insulating core, which accounts for the execelent insulation.

Sandwich Panel Installation process

Accessories and Endings

Front shot


The front cover protects the insulating polyurethane core when it is exposed on the front of the roof for sandwich sheet roofs, thus ensuring maximum performance over a long period of time. In order to provide a total aesthetic integration, it is manufactured in the same finish as the five frets Sandwich Panels.


The ridge or ridge cap to two waters protects the union of the two cloths of a sandwich cover, avoiding that they pass the precipitations and other external agents, like the birds that usually nest in these points. Its angle of fall is adaptable and it is manufactured with the same profile of the Three Fret Sandwich Panel to ensure a total enclosure.

Front shot


When the cloth of a sandwich cover starts from a higher wall, it is recommended to install the ridge cap to the wall to provide better sealing against leaks and humidity. In addition, it is manufactured in the same color as the Sandwich Panel at the lowest price m² for extraordinary performance.


The lateral finish covers the polyurethane foam that is exposed on the side of the roof plates; a very vulnerable point in front of precipitations and humidities that damage the insulating core and therefore reduce the performance of the installation. The lateral finish prevents these damages with a simple installation.

Front shot


The lateral wall finish covers the meeting between the side of the sandwich sheet roof and the adjacent wall, which continues above the roof and , therefore, slip water that seeps into the insulating core of the Sandwich Panel Cover or even the inside the building, causing serious damage.


The water pipe collects the precipitations that fall on the roof sheets and evacuate them separately, avoiding the problems that usually cause the water curtains. It is a very simple installation that allows highlighting the qualities of the Sandwich Panels at a minimum price.

With all the orders that we manufacture at the best price in Panel Sandwich Group we provide the specific screws for the installation of these roof plates; Normally it is about mounting on a metal structure, although on request we also offer fixings for wood, laminated beam and concrete.
