| | | Specific thermal conductance of the panel: standard 54 = 0,73 W/m2K plus 66 = 0,60 W/m2K H89 = 0,44 W/m2K Water vapour permeability: transpiring system with open joints. Water Vapour Permeability: u=86 Water Absorption: under full water immersion after one hour less than 0,03 Kg/m2 Panel weight: 20 Kg/m2 (average weight) Resistance under wind suction test: variable from 3300 N/m2 (min) to 6270 N/m2 (max) depending on panel size and type of joint. Impact Resistance: in compliance with category I e III ETAG 17. The system passes the impact soft test (400 Joule) and hard impact test (10 Joule). Reaction to fire: Euroclass E (corresponding to former Italian classification class 1 - art. 8 MD 26-06-1984 or French classification M1) | | The PIZ panel is available in the following sizes with 0 mm or 15 mm joint | | |
| | | The PIZ system can be mounted on any surface (reinforced cement, brick, metal structure, etc.). In case of renovation work, no preliminary activity or cleaning of the support surface is required. Architectural panels are fixed on the surface by means of an anchoring system and of special section bars. Installation requires simple mechanical operations; no skilled workers or special components other than those provided with the system are necessary. Panels are mounted in a horizontal direction. Vertically, the installation is performed from bottom to top. Standard arrangements can be accomplished with both heights of insulating Zecca panel; carefully designed alternate patterns of height and width can also be realised. | | |

| | | PIZ is an innovative cladding system for civil and industrial buildings. The structure is installed by securing light alloy guides on the surface to be covered and then fixing the insulating Zecca panels on these guides. The panel is made up of a modified fibre-reinforced cement mortar layer coupled with a slab of insulating material. The grooves on the upper and lower edges of the cement element serve the purpose of housing the assembly sections. PIZ was developed to satisfy the growing needs of the construction market in terms of energy savings and architectural improvement. The system is designed for covering all types of buildings, both new and under restructuring. | | |

| | | COLOURS AND FINISHES | | |
| | | |
| | | Thanks to the wide range of colours and finishes, it is always possible to identify the best solution for a building to meet the customer's specific needs. Eight basic colours (plus white) are available in 5 shades, generating a palette of 40 colours. Four finishes are provided: smooth, rough, granular and grooved. | | |

| | | PIZ and photocatalysis | | |
| | | Panels are available in standard sizes (see building table) with a +/- 20 mm variation | | |
| | | |
| | | In cooperation with the "Politecnico di Milano" Technical University, Zecca Prefabbricati S.p.A. has developed PIZ I.S., a cladding system obtained using titanium dioxide to alter the material's surface characteristics, generating photocatalysis and superhydrophilicity. | | |
| | | |
| | | |
| | | Self-cleaning properties | | |
| | | |
| | | Thanks to its special dirt-resistant characteristics, PIZ I.S. enables to contain cleaning and maintenance costs, exploiting the chemical reaction following light absorption by a catalyst, also known as superhydrophilicity. This phenomenon enables the water to spread evenly on the surface without generating drops. Thus, PIZ I.S. cladded walls are permanently covered by an invisible film generated by dampness in the air, which prevents the dirt from adhering to the wall. Any dirt may easily be removed with water. | | |
| | | |
| | | Reduction of air pollution and anti-bacterial properties | | |
| | | |
| | | A photocatalyst is a substance which uses sunlight to improve a chemical reaction without undergoing changes. During photosynthesis, for example, chlorophyll is a photocatalyst. When a photocatalyst absorbs natural or artificial UV rays, it produces couples of electrons and holes in the valence band. These holes have a strong oxidizing power, whereas electrons have a strong reducing power. When these couples of holes and electrons react with the dampness on the surface, the oxidizing power leads to the production of hydrogen radicals, which in turn react with pollutants and bacteria in the atmosphere. These are then decomposed into non-polluting substances which are easily washed away by the rain. | | |
