Architecture

We innovate in the creation of unique facades and architectural elements using precast concrete, GlassFibre Reinforced Concrete and UHPC. We work closely with architects, engineers and contractors to design and manufacture sustainable and durable facades, custom-designed for any project.

GlassFibre Reinforced Concrete

Through R&D and modern production techniques we support architects, investors and builders to create unique, durable and sustainable facades.

We develop special concretes, such as GFRC and UHPC, for the construction of durable, versatile and lightweight facades. In particular, the use of GFRC in the design of the shell gives maximum design freedom to the architect as the material is extremely flexible and therefore the possibilities are almost unlimited.

What is GFRC?

GFRC (or GRC, Glass Fiber Reinforced Concrete) is concrete reinforced with glass fibers and is the technological evolution of precast concrete, maintaining the advantages of industrial prefabrication. GFRC elements are manufactured using a special spraying technique on specially shaped moulds. Then there is careful maintenance of the elements, special surface treatments and finally the elements are transferred and hung in the project.

Today, GFRC is considered one of the most innovative and sustainable facade construction materials worldwide and is used in internationally recognized projects as cladding on building exteriors, parapets, bullnoses and even decorative elements.

The key benefits of GFRC

The long life, its low weight and the great formability it allows are the main characteristics of GFRC that make it one of the most modern architectural facade materials suitable for both new constructions and renovation projects.

GFRC has significantly higher flexural, tensile and impact strength compared to other facade materials. GFRC elements are manufactured using a special spraying technique that allows for a low water/cement ratio, low thickness and high strength. Due to the inherent characteristics of the material and the use of acrylic polymers within the mix, rainwater absorption and oxidation from the air are significantly reduced, allowing GFRC curtains to maintain an unchanged image over time and have zero maintenance needs.

GFRC is a new material for Greece, which stands out because it enables architects to achieve maximum flexibility in the design of complex surfaces, such as curved, convex, wavy with various reliefs, textures and colors in the body of the material. It is an industrial product produced by spraying the mixture onto molds of the desired shape and size. There is virtually no limit to the shape or profile that can be created in a variety of smooth, rough and unique textures.

The ability to be produced in thin cross-sections (10-13 mm), gives GFRC the advantage of not burdening the load-bearing body with additional loads and being easy to handle on site even in large panels. . A typical GFRC cladding sheet is approximately 70% – 90% lighter than its reinforced concrete counterpart and weighs between 30 and 45 Kg/m2.

GFRC is a sustainable, environmentally friendly material with a lifespan of over 100 years. We follow an environmentally friendly production process without toxic materials and with low energy consumption. Research shows that the production of GFRC consumes significantly less energy than other popular facade materials. It may be that global cement production accounts for about 5% of global CO2 emissions, but GFRC although rich in cement, has very little weight (90% lower than concrete) and thickness, thus reducing the actual content of the project.CO2 emissions are further reduced if the reduced weight load in construction is taken into account with the resulting savings in structural elements and building foundations. Our production is 100% customized and dedicated to each project, resulting in the minimum possible waste of materials. As a result most GFRC-clad buildings achieve high BREEAM and LEED ratings, and it is easy for project stakeholders to assess the environmental impact of GFRC elements.

GFRC is a non-combustible material and releases negligible smoke emissions in a fire. Belongs to fire protection class A1 (“non-combustible” according to DIN 4102)

GFRC is a natural material, perfectly adapted to the environment. Its raw materials come from nature and the production processes do not include any chemical treatment. It is an authentic, living material that changes naturally under temperature changes and weather conditions, but without losing its mechanical and physical properties.

GEOMETRY

Each project is unique.

GFRC elements can be produced in any shape and dimension starting from small panels up to monolithic elements larger than 20 sq.m. By manufacturing the molds in-house, we achieve even the most complex geometries, such as double-curved, convex, concave, wavy and ridged surfaces.

The large panel sizes combined with the wide range of shapes and geometries mean that there is no need to interrupt the material and this is what gives the impression that the building shell was constructed in “one piece” while at the same time highlighting the purity of the architectural design.

COLORS & SURFACES

By creating a wide range of surfaces and colors we give each project a unique identity.

GFRC has a key advantage over other “color treated” materials that undergo solid coloring with paint. The color is incorporated into the GRC as it is added during the production of the mixture along with the other raw materials. Thus, we achieve any color variation and tone in GRC.

Using special molds we form GFRC elements with geometric patterns and reliefs that create an exciting interplay of light and shadow that changes depending on the viewing angle.

Finally, if we apply special techniques to the surface of the GFRC, we create textures that give a “liveness” to the facade.

SPECIAL APPLICATIONS GFRC, HPC & UHPC

Perforated panels, claustra, barriers, special corner elements, column cladding elements and cornices are some more of the possibilities of GFRC.

We support project contributors at all stages of the project, from the first phase of planning to implementation.

DESIGN

Our goal is to contribute supportively to develop a complete, functional and aesthetically flawless solution already from the design phase of the project, thus ensuring the final result.

After discussing with the project engineers, we consider customized solutions and propose various technical solutions.

We can support you in:

  • Design and analysis in GFRC panels of the facade with the criterion of maximum aesthetic and economic performance.
  • Samples and mock-ups.
  • Static calculation of the facade and supports.
  • Construction details and solutions for special cases (BIM supported).
  • Project costing and value engineering

PLACEMENT

Various factors may influence and determine the installation method of GFRC investments. These can be location, height, environment, mounting systems, panel sizes and more.
The specialized installation crew of ARMOS undertakes the installation work, and can also train other colleagues and manufacturers in the method.
