Solution 3

Stratigraphy on wooden floor slab with the Ondulit/Coverib multilayer protective sheet as top surface

Solution for wooden slab with beams and joists supporting wooden planking on the soffit. The insulation package is interposed between wooden battens to form a support for ventilation, through the use of suitable slotted metal elements and multilayer sheet as a watertight element.

Main advantages

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