Wall cladding, protection and covering systems for vertical civil and industrial structures in Okoumè wood or Thermowood as well as heated ventilation systems suitable to optimize the thermal insulation as ventilated facade, preserving the building from aging and reducing the environment impact, while increasing sound insulation. The system is made of solid sawed wood elements, which have been dried in Italy according to the SDSP process. Sections of 42x42 mm or 25x37 mm with lengths from 600 to 3,000 mm and higher. Suitable as ventilated façades, sound protection reducing noise by about 8-12 dB, sunscreen, covering of technical compartments or decorative element. Installation should be carried out by fixing the single stainless steel profiles, L.1485, using no.4 screws/plugs with a diameter of 10 mm and a variable length depending on the structure of the wall and making sure it can support 25 kg/m. These profiles should be placed at an inner distance of 400/500 mm, or at a maximum of 600 mm in order to preserve any warping in the wood. The wood elements will have to be run through the holes or fixed by a front joint to the holes on the stainless steel profiles.
