Scopri di più e personalizza Rifiuta Accetta The Polycarbonate Home The Polycarbonate What is Polycarbonate? The family of polycarbonates includes the technopolymers composed by monomers bound together by carbonate groups. From their chemical structure we can derive the unique properties that characterize them. In fact, compared to other polymers, the excellent transparency qualities to let the visible light pass and the impact strength are outstanding features of these materials. Moreover, thanks to the high lightness, the excellent mechanical properties and the thermal insulation they are widely used in many fields, such as in construction. Energy Saving and Sustainability Thanks to the various properties of multi-wall PC sheets, it is possible to maximize the benefits of natural resources such as solar lighting and sun irradiation, resulting in lower conditioning and heating costs, with advantages in terms of interior living comfort, air recirculation and greenhouse effect removal. Moreover, all polycarbonate products are100% recyclable and a minimum amount of energy is enough to reach the low melting temperatures for both production and recycling. The energy balance analysis, carried out in accordance with the EN 12831 standard, highlights the greater fuel requirements necessary for heating an industrial building using glass windows compared to the same building with PC multiwall translucent inserts. Our products make it possible to edify buildings complying with the latest regulations for thermal insulation and energy saving. Versatility of use Polycarbonate panels are used in both the industrial and construction field, indoor and outdoor installations, such as translucent roofings, skylights, windows, pedestrian tunnels, shelters, facades, building envelopes... ranging from the simple DIY work to the Urban upgrading requalification or the creation of contemporary design projects. Continuous research in technological innovation has enabled us to create a complete range of steel and aluminum accessories, constantly up-graded , to guarantee easy and safe installation systems in compliance with law-regulations for fire reaction, load resistance and building safety. Thermal insulation The multiwall internal structure of Polyarb®, arcoPlus® and arcoWall® profiles, characterized by multiple air cavities offers real advantages related to the building thermal insulation. Best thermal performance can be achieved using special systems such as arcoWall® and DoubleConnector®, which have been designed for being installed in the most cold areas such as Russia, Sweden and Iceland. Additionally windows and facades made with multiwall structures, thanks to the multiple reflection phenomena, provide special shielding performance against solar irradiation. UV protection Using the co-extrusion technology, the external side of the panel is produced with a special polycarbonate characterized by a high concentration of UV-absorbers. This peculiarity gives the product high resistance against chromatic variations, hailstorms and accidental shock, even after a long sun exposure. This ensures long lasting lifetime, reducing the weathering damage effects and delaying the natural PC aging. In addition, several treatments have been developed to further improve the solar irradiation management from the point of view of the sheet’s durability (UV tech treatment) and to eliminate the negative radiation’s consequences for the indoor environments (IR or Reflecto treatment) with consequent reduction of air conditioning costs. Lightness Being lighter than glass, polycarbonate products allow to create large building surfaces, both translucent and opaque, greatly reducing the installation costs both in terms of an easy-handling and of the load-bearing supporting structure. Moreover resistance performance is always guaranteed both for pressure and depression values as required by the current regulations. Mechanical Resistance A peculiarity of polycarbonate is the high resilience that gives the products a high resistance to accidental shocks and hail impact. At the same time they respond to the safety regulations regarding translucent surfaces in public and working environments. Resistance combined with flexibility make PC panels extremely versatile and easy to install. Transparency Polycarbonate’s most common feature is its transparency! By making the building surfaces translucent it is possible to maximize the benefit of natural lighting, thereby reducing the artificial light sources and thus obtaining both a high visual and a thermal comfort. Furthermore the polycarbonate sheets can be colored to further help complete the light management. Moreover, thanks to the Caleido project, the colored pigmentation allows to satisfy the most particular architectural solutions. Certifications The Regulation EU No. 305/2011 (CPR - Construction Products Regulation) prescribes to release a Performance Statement (DOP) and to display the CE marking on each building product that belongs to a Harmonized Standard application field or that complies with a European technical assessment. The DOP provides the essential characteristics of the product with its performance. These documents can be downloaded directly from our website, at the DOWNLOAD section, using a unique product identification (eg. PoliCarb® 10mm). Moreover the CE mark and the Harmonized standard are printed on the pallet label citing all the products contained therein. Currently the dott.gallina products certified with CE marking are: Policarb®, arcoPlus® and arcoWall®, flat panels and sheets made with multiwall polycarbonate, according to UNI EN 16153: 2015 TegoLUX®, polycarbonate solid corrugated panels, according to UNI EN 1013: 2015 - PoliComp® and Scudo® solid sheets according to the standard UNI EN 16240: 2014 A PC granules, color, pigments and additive dispensers B Main extruder C UV coextruder D Vacuum gauge E Product marker F Protective film applicator G Cross-cutter H Packaging roller table Thanks to the internal management of the entire production process and the in-house manufacturing of extrusion machineries, our company can offer customized products according to each specific requirement. The value of dott. gallina products lies mainly in the technical know-how that is expressed by a capacity for innovation with a continuous updating of our product range in order to abide by our customers’ requirements.
