THE TECNO-BUILD® BEARING STRUCTURE IS DESIGNED TO BE FITTED OUT WITH ANY KIND OF ROOF REQUIRED BY THE CUSTOMER.

SECTIONS OF PRESSURE-BENT, GALVANIZED STEEL ABLE TO CONTAIN ANY KIND OF COVERAGE ARE FASTENED TO THE BEARING STRUCTURE BY MEANS OF BOLTS, SO THAT THE ROOF CANNOT BE LIFTED OFF IN CASE OF EXTREME WEATHER CONDITIONS; THESE SECTIONS HAVE HOLLOW SPACES THAT ENSURE VENTILATION OF THE ROOF. THE HOLLOW SPACES ARE HIDDEN BY GUTTER-SECTIONS OF PRESSURE-BENT, GALVANIZED STEEL.
A SPECIAL SECTION OF PRESSURE-BENT, GALVANIZED STEEL IS POSITIONED ON THE ROOF RIDGE AND ANCHORED FROM THE INSIDE TO THE BEARING STRUCTURE.

IN ORDER TO ALSO ENSURE ‘VENTILATION’ OF THE ROOF AND OF ALL OUTER SURFACES OF THE CONSTRUCTION – AND THE RELEVANT ADVANTAGES IN TERMS OF LIVING COMFORT AND LACK OF INDOOR HUMIDITY – WE PROPOSE THREE TYPES OF ROOF.

TYPE 1:

The roof consists of:

  • A primary structure made up of a series of frames of pressure-bent, galvanized steel (thickness: 6 cm) having the same design length and shape as the roof, properly reinforced with cross-beams of pressure-bent, galvanized steel, joined by riveting and without welding; the structure is properly perforated in order to allow air recirculation, as well as passage of the components of the electric installations, if needed.
  • Outside the primary structure, a 10 cm thick, self-bearing sandwich panel is installed, consisting of an internal sheet of pre-painted, galvanized steel, 0.4 mm thick, and an external sheet of pre-painted, galvanized steel, 0.5 mm thick, shaped like curved tiles. The polyurethane insulation is inserted between the two sheets.
  • Inside the primary structure, plasterboard sheets are applied, which shall be subsequently grouted, levelled and painted.
  • The total thickness of the roof is 22 cm.
  • This type of roof is high-performing, having a heat transfer coefficient of 0.168 W/m2K, and therefore it is recommended in housing structures where thermal insulation plays a critical role.
  • All roof components are recyclable.

TYPE 2:

  • The roof consists of a 10 cm thick, self-bearing sandwich panel, made up of an internal sheet of pre-painted, galvanized steel, 0.4 mm thick, and an external sheet of pre-painted, galvanized steel, 0.5 mm thick, shaped like curved tiles. The polyurethane insulation is inserted between the two sheets.
  • The total thickness of the roof is 15 cm.
  • This type of roof has a heat transfer coefficient of 0.18 W/m2K.
  • The inside of the roof can be lined with plasterboard sheets, which shall be subsequently grouted, levelled and painted.
  • All roof components are recyclable.

TYPE 3:

  • The roof consists of a series of PVC slats.
  • Each slat has the following dimensions: width: 15 cm; depth: 7 cm; thickness: 3 mm; height: design height.
  • Inside, the slat is divided into six chambers that perform various functions, i.e:
    • Allowing air passage and, as a result, a high-value ventilation as already discussed.
    • Allowing passage of any electric installations.
  • The roof is obtained by assembling several slats fitted together through pressure or sliding.
  • This type of roof is most suited when the construction shall be used for initial reception and commercial purposes, especially in case of temporary / seasonal use, i.e. when there is a need to disassemble and reassemble it several times.
  • This type of roof is recommended in constructions where hygiene and sanitization play a vital role; indeed, it is compatible with the use of high-pressure washers.
  • This roof has a heat transfer coefficient of 0.69 W/m2K, and therefore it is recommended in commercial constructions (kiosks, toilets, etc.).
  • The roof of PVC slats can be coated with sheets of pre-painted, galvanized steel or with tile-shaped sheets of galvanized steel.
  • The total thickness of the roof is comprised between 7 cm and 12 cm according to the outer finishing chosen by the Customer.
  • All roof components are recyclable.
