Polycon glassfiber reinforced concrete (GFRC) is manufactued in the Czech Republic. GFRC is a composite material made of sand, cement and special alkali resistant glassfibers as reinforcing element. The use of fiberglass gives concrete higher elasticity module and tensile strenght, allowing the production not only of flat fassade panels but also of curved or formed elements in 3D, a feature very appreciated by architects and designers.
GFRC can have the characteristic concrete grey look or it can be thoroughly pigmented in a variety of earthly colors (white, anthracite, brick-red, light green, brown, beige, black) obtained using natural pigments. With superficial (non thorugh-body) color coating it is otherwise possible to have any RAL or NCS color. Fire rating of GFRC is A1, fully incombustible.
Concrete is a porous material and the surface should therefore be treated for waterproofing and stain resistance, particularly if used outdoor. This hydrophobation treatment is done by the manufacturer. An optional impregnation treatment can be added for improved stain resistance and for the easier removal of graffiti. This treatment gives a satin (slightly shiny) look to the surface and can be applied either by the manufacturer or also also later on site.
Polycon GFRC surface can be smooth, rough or textured in a wide variety of different shapes (for texture examples see http://www.reckli.net/strukturmatrizen.html?&L=5). The surface can also be decorated with any standard or individually designed motif using the technique developed by Graphic Concrete® (see http://www.graphicconcrete.fi/)
Polycon GFRC is produced in the exact sizes requested by each project, eliminating any waste cost. Theoretically there is no maximum size, but in practical terms panels larger than ca. 1600×4200 mm are very difficult to handle and install. Panel thickness depends from size and surface texture ; the standard thickness for flat panels is 13 mm.
Polycon GFRC concrete has a standard 5 years guarantee that can be extended to 10 years in certain cases.
