Solution 2

Stratigraphy on metal structure with the Ondulit/Coverib multilayer protective sheet as top surface

Solution for roofing on metal structure beams, with its load guaranteed by the use of the slab sheet, insulated with mineral wool or polystyrene with interposed Z-shaped metal profile. The slotted omega element ensures continuous ventilation below the multilayer sheet.

Main advantages

  1. High energy and acoustic performance with large span between the purlins.
  2. High mechanical strength.
  3. Reduction of heat input to the building thanks to ventilation.
  4. High reflective power of the sheet.
  5. Rapid dispersion of accumulated heat.
  6. Efficient stratigraphy from the hygrometric viewpoint (interstitial condensation).
  7. Ease of connection with exposed elements or skylights.
  8. Free use of high-performance mineral wool or wood fibre insulation (NO PUR).
  9. The presence of an waterproof membrane to protect the insulating layer guarantees its durability, health and constant thermal performance over time.
  10. Internal airtightness (guaranteed by the first sheet placed on the structural metal sheet).
