Naturalness that endures

Viroc® Cement Bonded Particle Board

V-urban® Cement Bonded Particle Board

Viroc is a composite panel consisting of a mixture of wood particles and cement called the Cement Bonded Particle Board (CBPB). It combines the flexibility of wood with the strength and durability of cement, allowing a wide range of applications both indoors and outdoors. The production of Viroc panel complies with the specifications of EN 634 and EN 13986 standards and carries the CE Marking Certificate.

The Viroc panel has a heterogeneous appearance with different shades randomly dispersed, resulting from the natural colours of the raw materials used and the chemical reactions. Tone differences may be observed on the same face, between the faces of the same panel or between different productions batches.

V-urban® Cement Bonded Particle Board

V-Urban is a Viroc panel with varnish finish intended to be applied to ventilated facades. It has QB certification (Qualité pour le Bâtiment / Quality in Building) and has an Avis Technique Approval Document issued by the CSTB.

The panels, when leaving the factory for transportation, are protected by a waterproof plastic screen. The side edges are protected with L-shaped cardboard including those in contact with the strapping of the packaging system. The protection of these edges should be maintained until the date of installation of the panels.

Viroc panels should be stored in a covered area, protected from sunlight and rain, with a flat and horizontal base. Pallets should be placed on supports high enough (≥8 cm) for easy forklift access. The maximum distance between supports should not exceed 800 mm and the distance between the first support and the top of the pallet should not exceed 210 mm.

If the pallets are piled on top of each other, all the support bases must be aligned to prevent deformation. It is allowed to pile up to 6 pallets, with a maximum of 4 meters.


Siempre que sea posible, la manipulación de los paneles debe realizarse utilizando los equipos Whenever possible, the handling of the panels should be performed using appropriate equipment such as forklifts or plate lifts.

When the panels have to be moved manually, they must be moved one by one in an upright position to remain flat and not deformed.

The panels are heavy, so their manual movement should not be performed without sufficient people being present.

Good manual handling practices should be followed, using appropriate personal protective equipment and following the rules of European Health and Safety legislation, (Factsheet 73).


When leaving the factory, the panels have a humidity of 6 to 12%.

To ensure proper installation conditions, the panel must adapt to the temperature and humidity conditions of the installation location. To do this, the straps should be cut and the protective plastic removed from the pallets. Prior to application, the panels must be at rest for at least 72 hours to acclimate to the installation site.

During acclimatization, the panels at the top of the pallets, whose straps have already been removed, may buckle, forming an upward facing concavity. This phenomenon is natural and happens due to the differential loss of moisture between the two surfaces. This process is reversible. The panel will be flat again if turned upside down with the face up. The same effect will be achieved by wetting the concave face (surface up) with water.

Cutting, drilling and machining

Boards can be cut, drilled and machined with power or compressed air tools commonly used in carpentry or mechanical metalwork.

Cutting, drilling and machining of Viroc and V-Urban boards releases dust that may contain traces of silica and cement constituent material. Appropriate personal protective equipment such as masks, gloves, goggles, etc. should be worn.


The cutting of Viroc boards must be performed with circular saws with high wear-resistant carbide (tungsten) or diamond cutters. To make multiple cuts or to cut boards with a thickness of 19 mm or greater, a horizontal cutting table should be used. The cutting table will increase profitability.


Drilling should be performed with non-impact drills using HSS (High Speed Steel) drills suitable for drilling metal.

Edge machining

Simple edge machining can be carried out on site using a portable router. Using the correct cutter, edges can be made by: Bevelling, rounding, grooving, etc.

The board edges may be supplied with factory grooves, tongue and groove or halved joint.


Viroc_Aplicações_Fachadas 8

Viroc panels can be applied outdoors, namely in ventilated facades, and is the ideal solution for outdoor linings thanks to their indisputable thermal insulation benefits.

The minimum thickness of the panel for application in facades is 12mm.

Protection of the panels through a coating of paint or varnish is recommended.


Viroc_Aplicações_Pavimentos 1

The construction of structural floors or lining for floors is another possible application of Viroc panels.

They are often used in the refurbishment of old buildings, replacing traditional wooden floors that deteriorate with water in the bathroom and kitchen areas and in zones connected to the facade walls.

The panels can be used to as a lining and finish on top of existing flooring.

The minimum thickness of the panels used in structural flooring is 19mm.
When used as a lining, with no structural function and laid on top of an existing floor, the recommended thickness is 12mm.

When applied as a flooring, pay attention to the loads that the Viroc panels will be subject to, given that the resistance depends on the thickness of the panel and the gaps between the supporting beams.

A coating of suitable paint or varnish to make the floors resistant to wear and tear is recommended.


Partition Walls

Viroc_Aplicações_Paredes 2

Viroc panels are also suitable for the construction of dividing walls.

When applied outdoors, the same rules apply as for the ventilated facades system.

An excellent solution thanks to the appearance, mechanical resistance, acoustic insulation, fire-repelling properties and durability of the panels.

It is the preferred choice for divisions in hotel rooms or cinemas, where acoustic insulation to airborne sound and fire-retardance are crucial aspects. Indoor damp areas are also ideal for using Viroc panels thanks to their resistance to dampness, such as swimming pool complexes, changing rooms and bathrooms.

Viroc panels can also be used to line walls, both indoor and outdoor.

The minimum thickness of the Viroc panels used in indoor walls in dry zones is 10mm and 12mm when applied in damp indoor or outdoor zones.

In damp zones, a coating of paint or varnish is recommended.

False Ceilings

Viroc_Aplicações_Tetos 1

The Viroc panel is also used in false ceilings both indoors and outdoors, for its aesthetics and durability.

When applying false ceilings, open joints between panels must be provided, both indoors and outdoors.

The minimum thickness of Viroc panels used in indoor ceilings in dry areas is 10 mm and 12 mm in wet areas, whether indoor or outdoor.

In damp areas it is recommended to apply paint or varnish.

It is also suitable for supporting roof coatings, due to its mechanical resistance, insulation index to aerial sounds, thermal resistance and humidity resistance.


Viroc_Aplicações_Mobiliário 1

Viroc panels can be used for indoor and outdoor furniture.

It is a waterproof material, although if the panels are used outdoors or in damp zones they should be varnished.

A lasting solution given the high durability and load resistance of this material



Thanks to their recognised versatility, Viroc panels are also used in furniture, stairs, dividing walls, doors, worktops and other decorative and architectural items.

The possibilities are endless.

Lost Formwork

Viroc_Aplicações_Cofragem Perdida

The strength and durability of the Viroc board make it an excellent performing product for lost formwork. In order to minimize waste, the board must be cut crosswise along its longest dimension, forming boards with a width of 1250 mm and the intended length.

The width of lost formwork boards is determined by the spacing between beams, whether metallic or reinforced concrete, plus 5 cm on each side, which is the minimum width for support on the beams.

Viroc panel is supplied raw, unfinished. The surfaces have some irregularities and imperfections, such as small incrustations, marks, scratches and salts from chemical reactions.

Whenever the panel is to be applied to open view, even if a varnish finish is not planned, a surface cleaning/polishing must be performed with a cleaning disc to remove dust, scratches, dirt and salts.

The cleaning/polishing does not change the natural look of the panel, it will remain the stains and heterogeneities that characterize it, as well as some salts and incrustations that are embedded in the surface. Viroc has suitable cleaning discs, that will be supplied upon request.

We recommend that the panel should have a finish with a varnished, to protected and make maintenance and cleaning easier.

Surface preparation

Whenever the panel is to be applied to open view, even if a varnish finish is not planned, a surface cleaning/polishing must be performed with a cleaning disc to remove dust, scratches, dirt and salts.

The cleaning/polishing does not change the natural look of the panel, it will remain the stains and heterogeneities that characterize it, as well as some salts and incrustations that are embedded in the surface. Viroc has suitable cleaning discs, that will be supplied upon request.

Before applying the finish, the panels must be cleaned with a breath of air or, preferably, suction in order to be free of any type of dust, which will damage the finish.

Cleaning exemple of a panel carried out on site with an orbital sander


The application of varnish on the Viroc panel aims to protect against aggressions of the environment where it is inserted, such as sun and weather exposure, increasing durability, facilitating cleaning and maintaining its appearance over time.

Applying a varnish may change the natural color tone of the Viroc panel, giving it a “wet” look with some gloss. Before applying varnish to the panels, the surfaces must be completely clean and dry, without grease, dust or surface salts. Surface cleaning should be done by polishing with a cleaning disc or alternatively sanding the surface with fine grit sandpaper 120 or higher.

There are no specific paints and varnishes to apply to Viroc. The panel has a surface alkalinity (PH) of 11 to 13, so that paints and varnishes suitable for both concrete and wood surfaces are usually the best performers when applied to the Viroc panel.

Solvent-based varnishes with acrylic or aliphatic polyurethane resins are the ones that have shown the best performances. Water-based, acrylic or aliphatic polyurethane varnishes are the ones that least change the natural color of the panel.

In addition to the above characteristics, paints and varnishes must be suitable for their intended purpose. For example, if it is an exterior facade the paint/varnish must be suitable for use on exterior walls, if it is an interior floor the paint/varnish must have hardness and strength suitable for use in floors.

The use of Viroc panels on kitchen worktops and shower cubicles should be protected with a paint / varnish that does not degrade in permanent contact with water.

In general, the varnishes are easy to apply, but it is very important to note that the application must be continuous and constant, to ensure the homogeneity of the finish on the panel and so that the surface is not stained and with different shades. Panels should always be painted/varnished on both sides and tops, the application procedures, provided by the respective manufacturers, must always be followed in the recommended coats.

Sanded / Calibrated

When required, panels can be supplied sanded / calibrated.

The calibration of the panels consists of thinning the surfaces with coarse sandpaper in order to minimize the variation in thickness.

Particularly when it is used as a support floor and the covering is a thin layer like a linoleum or vinyl canvas.

Once sanded, the surfaces are left with visible wood particles. The sanded panel has no decorative features, to be visible.

At a location that combines urban and countryside experiences, one finds a school where colour is king.

The choice of material for its façades, which incorporate an original ventilation system, was the Viroc panels in its different colours.

The campus was designed in a wide-open green area where the buildings have interior gardens.

In buildings of one or two storeys, moulded to the landscape as if they were a pathway, the volumetry blossoms into a town, permeated by streets that cross it and allow one to see inside it.

At the heart of the complex is the kindergarten and primary school, where volumes with gardens and orchards characterise the educative facilities. The interior gardens look out onto the streets, while the classrooms are organised symmetrically at the bottom of the garden, facing an ample corridor. The coloured Viroc panels give life to the building, as well as thermal protection and controlled ventilation.

The panels were chosen because they are durable outdoors and waterproof. The colours make is a vivacious building where the children are happy to be.

Aiming to create large open spaces and more efficient living in Philadelphia neighborhoods, Manifest AD atelier, in conjunction with Postgreenhomes, created a duplex house that has been replicated. Having already worked with fiber cement, they discovered that Viroc was the solution for these buildings, as it is “raw”, a natural material that varies from panel to panel. The wood present in the panels helps to reduce the carbon footprint of a typical cement panel, and also adds thermal efficiency and sound insulation improvements.

The atelier used Corten steel accents on the facade with Viroc, so that the contrast of these two natural materials with each other creates a dramatic facade, gaining life, rust and marks of time.

The interior works with an open kitchen, dining room and living room with access to a patio. The remaining spaces open to a large window that brings more light and air into the rooms than usual. Space flows from the inside to the outside.

Location: Porto, Portugal

Located besides the famous Fonte Monumental de Mouzinho da Silveira (Mouzinho da Silveira Monumental Fountain), in the city of Porto, this new shop of the Fora Sunglasses chain is notable for the remarkable design of its displayer, customer counter, display case and vertical stairway to the shop’s storeroom located on the first floor.

Drawing inspiration from the granite that designs the city of Porto, this shop was fitted out using a cement and wood composite material called Viroc, which combines with the reinforced screed floor to form harmonious grey tones that enable certain architectural items to be highlighted using the white colour.

The displayer comprises two structures in a scythe shape that are positioned separately in one of the corners of the shop, as if dancing with each other: this Viroc construction serves to store the glasses in drawers and host display shelves in white lacquered wood. The shelves unify the two structures and subtly exacerbate the perception of movement characteristic of a dance.

The customer counter is light, with a slim design and a small volume that perfectly serves its function, aided by a block of drawers on wheels. The lightness of this counter is achieved by using the Viroc which merges into the reinforced screed flooring.

The display case, split into two modules, was designed for two purposes. It stores the sunglasses in drawers in the lower part and provides information about the product through an acrylic box illuminated from above.

The stairway connects the shop to its storeroom, and is made from white lacquered iron in a spiral that contributes to the theme suggested by the displayer of architecture in movement.

An ecological retreat from urban life. Nominated for the Archdaily Building of the Year 2020.

This house is a prefabricated residence, an alternative to a luxury home, which minimises the environmental impact of new buildings. Ready in 99 days and built from environmentally responsible materials, it fits harmoniously into the urban landscape.

As the master Ludwig Mies Van der Rohe one day wrote, “less is more”. This is the premise that guides the ideas of the architects Rodrigo Alegre and Carlos Acosta (founders of the Mexico City STUDIOROCA, the design company responsible for the elegant interior furniture brand VMD). The goal is to experience and appreciate the natural beauty of Mexico with the smallest ecological footprint possible.

Viroc emerges as the main material for outdoor façades, combining the best features of wood through its flexibility and the endurance of cement. Among its many beneficial properties, it is non-toxic, waterproof, fire-retardant, it provides thermal and acoustic insulation, and its natural beauty emphasises the modern character of any home. Valchromat is used as a lining, endowing that touch of class needed in a luxury house. Waterproof by default, fire-retardant, natural and a full palette of colours available.

This low-cost, uncomplicated building solution provides a non-invasive connection with nature, harmoniously combining a natural and accessible luxurious environment. Viroc and Valchromat could not be prouder to be part of this project.

Application: Roofs and facades

Architecture: Carmina Casajuana, Beatriz G.Casares e Marcos González, Atelier MYCC

Photograph: FG + SG

Location: Spain

Built in three months and assembled in three days, this vacation house located in the Galician municipality of Cedeira is a good example of the many possibilities that modular construction, up to now associated with catalogue houses, offers today.
The program demanded by the client, along with the unique site of the house and modulation and transportation needs of prefabricated construction, inspired the design of this house built by the young Madrid studio MYCC, formed by Carmina Casajuana, Beatriz G. Casares and Marcos González.

The house is located on a steep slope, in a remote location in the northeast corner of the Iberian Peninsula, an area dominated by the imposing presence of the ocean and the slender forest of eucalyptus trees surrounding it. The terrain is surrounded by harvest fields, family farms and pitched roof houses. This image, protected by the area’s building codes, determined the geometry of the house that, simplified up to the point of evoking the basic house, was conceived as an autonomous piece that sits as a landscape observer and that speaks, with new terms, about the traditional language of the place.

The volume was wrapped with two materials with the purpose of setting up a dialogue with the landscape.
The roof and the side facades were covered with Viroc due to “it’s great strength efficiency in spite of being light and, therefore, is easy to maintain and move”.
According to Beatriz, Viroc was also chosen because of its concrete appearance and its “naturalness of being made of wood and not plastic”.
The two main facades of the house were clad with perforated corten trays following the schematized image of a forest silhouette, recreating the image of the surrounding vegetation.

After an assembly trial in the factory, and after making sure that everything fit in properly, the different modules and trusses of the building were taken apart to be packed and moved in trailers the whole 700 kilometers separating the factory from the remote seaside site where it was to be installed. All the parts were put together again on the designated site in just three days, and the finishing touch-ups were done in the following two weeks.
The end result is a high-quality product, designed with high standards of energy efficiency and sustainability.

Location: Portugal

The invitation to bid for the relocation of a kindergarten as part of an urban renewal plan offered an opportunity to reflect on a public building’s relationship with the rough surroundings of a suburban area while also working and experimenting bioclimatic concepts in a multidisciplinary project for a public space.

The signature of Nadir Bonaccorso on this project is unmistakable thanks to his exemplary respect for the principles of sustainable architecture.
The building has been constructed in bare white concrete. Its south side is covered with Viroc Black panels with protruding volumes for sun control offering a unique space for school activities.

The interior is covered with thermal insulation, almost like a second skin. A third skin in brick and plaster protects the insulation and guarantees thermal inertia inside the kindergarten. Heating is provided by a mixed system of solar panels and a gas boiler, which supplies hot water for normal use and heated flooring. The building is ventilated by the difference in pressure from forced air extraction in the toilets, entering the building via a system of grilles in the aluminium thermal frames.

According to Nadir Bonnacorso, “The assembled material constructs the space. I like using materials that show their own nature and Viroc panels have this characteristic. It’s a material that fits in with my construction of space.”

This bioclimatic building is an international reference today and received a special mention at the third edition of the Fassa Bortolo International Prize for Sustainable Architecture. In 2010 it was selected for the OECD Compendium of Exceptional Education Facilities.

Location: Portugal

Shelf House is a project by the architect Daniel Capela Duarte, of the Portuguese studio Mutant – Architecture & Design.

The project consists of the “mutation” of a family home of the 1960s. The ownersproposed an in-depth intervention in order to adapt that already existing for a new functional purpose and give it a new, typically contemporary image.The image of a shelf was the starting point for the conceptual development of the solution. A white border is added around the building’s facade, to convey the idea of a shelf and serving as the base for the volumes that partition the elevation and represent the books. The black volumes (Viroc Black) contain the intimate areas of the house, namely the bedrooms, while the wood-clad volumes represent the home’s social areas, i.e. the main entrance and living room.

The architect Daniel Capela Duarte states that the reasons for choosing Viroc for this project were “the versatility and the aesthetics of the product, which give it the ideal thickness to be compatible with a “capoto” system facade. Viroc also had the required colour, meaning that no painting was required”.

Location: Portugal

The plans for refurbishing Júlio Dantas Secondary School in Lagos, Portugal, were drawn up by the Carlos Almeida Marques – Arquitectura e Urbanismo, Lda studio, headed by architect Carlos Marques.

Carlos Marques, who was in charge of the refurbishment project, explains:

”We used Viroc for the interior walls of Júlio Dantas Secondary School, because we needed to create a system of dividing walls that could satisfy four technical requirements:

it had to be easy to pass cables and pipes through, in such a way that they were simple to install and could be connected and disconnected easily, in keeping with how each room was intended to be used, providing the best functional and spatial framework for those elements;

the material used had to withstand the intensive use typical of public buildings, especially schools, and Viroc offers the kind of durability and hard-wearing capabilities required in such projects;

the walls had to provide thermal and acoustic insulation, so several studies, trials and tests were conducted with Viroc’s technical assistance, enabling us to come up with an efficient and cost-effective response;

finally, the rooms had to be flexible, given that schoolrooms are often reorganized, and the highly mobile Viroc walls meant that this could be achieved easily and with the minimum of resources.

Given the challenges we face in construction today, we see Viroc as a material that offers a modern approach to 21st-century design and architecture.”

Ana Guerra is the architect responsible for redesigning a terrace adjacent to a modern apartment in a gated condominium of the city of Lisbon, Portugal.

“The intention was to create an environment that is conducive to parties, for meals and to enjoy summer afternoons and evenings. The design contains an area for Yoga, a table for six people, a bar and sofas. The VIROC “sideboard” includes the bar, hides the table and provides space for storing the sofa cushions”, explains the architect Ana Guerra.

The architect responsible for redesigning this terrace chose VIROC due “to its flexibility properties that allow it to create all the required forms (such as doors, drawers and table), its high weathering resistance, which means its components can permanently stay outdoors, and the contemporary aspect of the natural-looking materials, which fit the architectural language of the building where they are used without needing any finishing. VIROC possesses all these characteristics, giving the project the uniformity required for the intended result”.

Location: Spain

The Spanish architect’s office, Ensemble Studio, was given the mission of transforming the former Madrid Matador into a Reader’s House, a benchmark cultural centre for contemporary creation in the city of Madrid.

The project is developed by the Germán Sánchez Ruipérez Foundation and led by the Spanish architect Antón García-Abril. It maintains and enhances the original nature of the manufacturing facility, combining the interior metal structures and original exterior masonry walls with precast concrete and Viroc that are now added to the building. This marks a clear difference from the original building while keeping the memory of the site as its history embarks on a new direction.

Casa del Lector thus becomes a symbiotic correlation between the universe of books and the architecture where the art of the word seems to flow through its contemporary shapes and materials.

Casa del Lector can host cultural activities of all kinds, such as exhibitions, conferences, training courses, creativity workshops, music concerts, film and performing arts festivals. These activities combine with applied research to contribute to the creation of a reader who understands, appreciates, assimilates, shares and interprets the world, society and our time.

Viroc Grey was the material chosen for all floors and for installation on some walls and ceilings.

Location: Portugal

Joana Gouveia and Gonçalo Chivite from Portugal’s eCube studio were the architects of this store in Setúbal, Portugal.

The design process began by assuming that a space should have many possible uses and attract all kinds of users; a shopping area that could be easily tailored to any kind of activity.

According to Joana Gouveia and Gonçalo Chivite, the aim of the project was to “get away from the traditional idea of a store, without losing sight of the main aims, which were flexibility/adaptability, building cost and architectural value added”.

“With that in mind, we created a striking image for the building as a whole, balancing formal concepts to create impact for anybody looking at the building, and giving particular emphasis to the textures of the materials used to clad the facade, especially through the use of pre-fabricated panels of concrete and Viroc – a wood/cement composite.”

The choice of grey Viroc to clad the facade “was mainly due to its similarity with pre-fabricated concrete panels. This enabled continuity with the existing materials, creating a unitary object. We also used it for its intrinsic characteristics, because it can be applied flexibly for interiors and exteriors, enabling specific stereotomy and angles”.

This project from the Portuguese architecture studio Caiano Morgado Arquitectos involved refurbishing a flat on the top two storeys of a sea-front building.

The refurbishment had two main aims: to boost the flat’s link with the surrounding land- and seascape and to make it more functional.

According to the designers, the strategy developed for the Warborn Flat “was based on the bespoke principle, by exploring the inherent functionality of each area.

“The windows and balconies have been re-worked in order to enhance the scenic effect of the surroundings and emphasize the transition and link between the interior and exterior.

“Timber, white and Viroc define the flat’s various areas. Black glass provides a boundary element, and its reflections re-interpret the landscape and seascape.”

The sea and the horizon become omnipresent throughout the flat, whether framed by a window or briefly captured in a reflection.

Grey and black Viroc were used for the project, to clad walls and ceilings.

Location: Spain

The purpose of this project by Spanish architect Raul Montero Martínez was to refurbish a small flat in the historic centre of Pamplona in Spain.

The strategy was to release as much space as possible, make better use of the natural lighting, and make the flat more functional and dynamic through the use of hidden and fold-away modules that could be altered to suit requirements, such as working or sleeping.

It was decided to use a limited range of materials for the apartment. Grey Viroc panels were fitted vertically to form the dynamic modules, timber predominates on the floor and ceilings, some of the original beams having been refurbished, and the original brick wall has been left exposed, to emphasize features of the original construction.

According to the architect, Raul Montero Martínez, “the result is spectacular. The owner was very pleased and really likes the use of Viroc in his flat”.

This small flat has become a unique, functional space that can be altered according to needs, the use to which it is put, and even one’s mood.

This unique apartment in the centre of Barcelona once housed the water tanks for the adjoining building.

Inspired by the extreme functionality found on board boats and the minimalism of Japanese interiors, all the comforts of a hotel suite in a compact environment are provided within the 22sqm of useable area, the clean design being based on two materials: timber and grey Viroc.

Viroc is a waterproof material, is aesthetically attractive and is easy to work with. Along with timber, it was used for all of the apartment’s horizontal and vertical cladding and panelling.

The walls are designed to hide all of the furniture as part of a meticulous system comprising various opening mechanisms, which contain everything needed in a house. The result is a universe that changes according to the time of day.

An outside stairway connects the lower floor to the terrace, which rounds of the comfort provided by the flat with magnificent views of the city.

The aim of this project was the restoration of the interior of an apartment of the 1960s in the city of Vigo, in Spain.

This apartment was originally composed of many divisions, typical of 1960’s constructions. It has been transformed from all these little rooms into a large interior space divided only by furniture, where everything happens. All the rooms and bathrooms open to this large common area. Of particular note is the children’s bedroom which joins with this large common area during the day by opening a large sliding door.

According to the project managers, the architects Jordi Castro Andrade and Maria González Ferro, “to emphasize the large central space as the axis of the new home, we tried to give it, besides its large floor area, greater texture using Viroc Grey to create all the storage units and partitions of the apartment. Viroc is a material that gives each panel a subtly different texture, helping us to read the central space of the apartment.”

The new headquarters of the Faro Motorcycle Club, located in a main avenue in Faro, Portugal, was opened in the club’s 30th year. The event marked it out as one of Portugal’s and the world’s leading motorcycle clubs.

The project was designed by architect and motorcyclist Miguel Caetano, who “wanted to highlight the importance of the association, with its enterprising, irreverent, creative and social spirit, via an architectural structure that would serve as a monument”.

The building can be viewed as two volumes, one being “essentially white, recalling the Algarve’s architectural tradition, with cubic, easily understood forms, and bereft of decorative elements”, mainly housing areas used for the club’s internal affairs. The other is clad in grey Viroc panels, giving it a look that is “cutting edge and contemporary, incorporating the entrance hall and main room”, intended more for club members’ social activities.

In addition to offices, a bar, kitchen and toilets, this building also has a double bedroom and dormitories sleeping 12 people, a private kitchen, showers, a library, and a wide mezzanine over the bar.

Location: Spain

The purpose of this project, designed by architects Santiago Carroquino and Hans Finner, was to create a nursery school that fitted into its urban surroundings, comprising various eight-storey residential buildings and overlooking a public park.

The designers’ greatest concerns were to create a building that was as environmentally sustainable as possible, and which at the same time would be sufficiently versatile for the kinds of educational activities for which it was intended.

Concluding that the top of the building would be the most visible part, the architects chose to create a carpet of grass on the roof, which blends in with the adjacent park when seen from the surrounding buildings.

The façade structure, ventilated using grey Viroc, provides energy efficiency for the entire complex, and at the same time gives it a contemporary and sophisticated look, in addition to the solar panels installed on the roof.

The interior of the building, which is for children from 4 to 36 months old, is highly versatile. Small rooms can be combined to create larger areas, depending on the particular teaching programme being followed.

This building, at 12 Jordan Street, Liverpool, United Kingdom, is one of the few Victorian brick buildings remaining in the area.

After suffering a severe fire, the building was refurbished by Pearson Architects. The original appearance was retained, but it was converted into offices. The key to the refurbishment was adaptability. The creation of an open space divided solely by a central corridor frees up the side areas alongside the outer walls. The bricks, which are typical of Victorian buildings, are left exposed, and the spaces can be modified or adapted to suit users’ needs.

Viroc was chosen for this project mainly for its industrial aesthetic, durability and fire-resistance. According to the architect in charge of the project, Miles Pearson, “We were able to apply Viroc quickly, without the need for skirting boards or additional finishing. Viroc proved to be an excellent alternative to the plasterboard or painted walls that are seen in many buildings”.

In order to release the pressure of road traffic for pedestrians in the entire area of the Plaza de Europa, it has been developed a building of 3018 m2 completely buried whose cover forms a public space.

The simple geometry of the plant helps to optimize the use of the surface and only altered by an annex of facilities, whose facade is the result of the creation of the access ramp at the middle of the northeastern end of the building. Behind this unique building facade are located the control center, bathroom, water deposit and fire fightihng facilities.

Inside, the regular program of the isotropy functional and structural system have only an exception on the insertion of a longitudinal patio which absorbs the regulatory needs of natural ventilation, while visually connecting the parking level with the public space of the Plaza de Europa. This longitudinal section also represents an important source of natural light and houses inside the evacuation elements and vegetation that bring to mind the existing indigenous pine forest before the urbanization of the area.

“Plaça d’Europa Parking” is a project made almost with a single material: concrete. We used it in different ways: in situ, prefabricated, in tiles and in light-weight panels. Viroc offered us a solution in dry construction to keep the material harmony in the space, keeping the soul of the project.”, claimed Marià Castelló Martínez, architect of the project.

The resulting interior space is of great constructive simplicity and sincerity, reversing a general harmony. The structure is also partly enclosure and left visible. The facilities have been studied to relate to the structural grid and allowed to view, to appreciate its beauty.

In 2015, the artist held in the Angra do Heroísmo Museum (Terceira – Azores) a solo exhibition called “In Concrete”, where he exhibited, mostly painted work on Viroc.

Rui Melo, works, were characterized by Carlos Bessa as:

“(…) Rui Melo shows ability to counteract the static and dynamic, through a personal grammar particularized landscapes and viewpoints, involving a staged lighting that leads the eye of the beholder to the pit edges. (…) Pays attention to the care with which any of the works aims the precarious balance of tension. Voltage between which expands and contracts and between excess and containment. Duplicity and sustain balance, therefore, a kind of mapping of lightness. ”

In 2016, it was also selected as part of the exhibition ART MAP – Moving Art Project, and will participate with two painted works on Viroc. This event involved 120 artists from around the world.

Location: Netherlands

Timeless Amsterdam is a project that takes place in a vintage space, framing recovered objects with purposefully aged appearance on the top of a building in the city of Amsterdam.

The use of Viroc was the basis for giving shape to the intended rustic environment, having been used both in the interior wall clading and other details of interior decoration as well as in the facade of the space.

A place to visit as the surrounding area transports us to a journey between past and present with an incredible view over the city.

Application: Interior wall cladding

Location: A Proba do Caramiñal, Spain

Cine Elma (1950) is one of the most emblematic buildings of the municipality. Its use as a movie theater was replaced by the emerging theatrical activity.

The main goal of this rehabilitation project was to adapt the existing building to the needs of the theater. A new covering unites the whole theater to a single height, allowing to incorporate a large panoramic window that delimits great part of the building.

The characteristics of the building were recovered to the maximum, recovering openings in the façade that were covered over the years. This allowed to recover the visibility from the public spaces increasing the luminosity and fomenting the visual relation between the exterior and the internal activity of the theater.

The facades were painted in a light tonality allowing to emphasize the frames, structures and existing paintings. The new interventions (bathrooms, auditorium and technical rooms) are perceived as independent structures.

The seats are concentrated in the points of greater visibility and the circulations are carried out by the sides.

Several products were used for this rehabilitation, with a greater focus on Viroc and Valchromat.

Wine shop El Rincón del Chez, Spain

Technical Specifications

Product: Viroc Grey

Application: Partition Walls and Wall Cladding

Architecture: Araiz Floristán Arquitectos

Location: Pamplona, Navarra, Spain

El Rincón del Chez is a small space, about 15 square meters, formerly occupied by an ice cream shop that has been transformed into a shop for wine tasting.

It is integrated in Estafeta street – well known for its surroundings with the festival of San Fermin – using the textures and forms of the pavements of the street. It seeks to materialize the street in a small fragment.

The gray Viroc was chosen, together with oak wood, to make both walls, ceilings and furniture. The goal was to use materials present in the winemaking process.

Naturalidade que perdura.


No. In Europe asbestos has been prohibited since 2005 through the 2003/18/CE directive.

In indoor applications, the joints can be sealed using a polyurethane mastic.

We do not recommend sealing the panels on a facade.

he expected durability of a ventilated façade made from Viroc panels is the same as a wall built using traditional methods, which is normally considered 50 years.

The vast majority of problems occur in corners and split edges, owing to incorrect installation of the panels. They must be fixed so as to allow the dilation and shrinking of the panel caused by temperature and humidity variations.

Yes, we recommend that the panel be applied on a wooden or metal structure as if it was a lining.

The cement in the panels contains calcium salt, meaning that during the hydration reactions of the cement, salts are produced that rise to the surface (primary efflorescence). When the panels are installed outdoors, if they are not varnished, the salts may migrate to the surface (secondary efflorescence) after coming into contact with rainwater. This is more common in damp and cold climates.

Although the panel has a degree of flexibility, we do not recommend its application in a curve.  We recommend lining curved surfaces using a series of small straight stretches.

The panel density is 1350 ± 100 Kg per m3, so a 10-mm thick panel weighs 13.5 Kg/m2.

There are no specific paints or varnishes for Viroc panels. The panels have an alkaline surface (11 to 13 pH), so usually paints and varnishes suitable for concrete and wood simultaneously have the best results when used on Viroc panels. Solvent-based acrylic resin and aliphatic polyurethane paints and varnishes have shown the best results. Water-based acrylic resin and aliphatic polyurethane varnishes have the least effect in changing the original panel colour

A wood stain is a varnish used to colour wood. If the wood stain is suitable for the surface of the Viroc panel, mentioned in the previous question, it can be used.

Tungsten hard metal circular cutting discs are recommended. Diamond cutting discs are only recommended in saw benches.

A water jet cutter may be used and is as effective as a saw. Laser cutting is also possible, but the edges will have a burned look, on the black coloured panels.

No, the holes must be drilled by the installer.

Yes, a set of very high-quality installers have worked with Viroc.

Viroc panels can be used as a support material for a roof that will be lined. We do not recommend using Viroc panels as the lining of the roof. On flat or near flat surfaces, owing to higher exposure to the sun and puddles of water forming, the dry-damp cycles can lead to the appearance of small cracks in some panels.
