> the construction of walls type XIII in case of aninterposition of an insulating material from the outside (insulating cladding system),> the construction of walls type III (direct fixingmethod).Maestral® can also be used as decorative finish (screens, bases of buildings, road systems, covering… ) allowing the construction of a second cover for acoustical insulation. (seediagrams 5 and 6) , in order to ensure the easymaintenance of the system (replacement of the Maestral®).
Meastral 7 : 106 mmMaestral 4 : 76 mm (see diagrams 5 and 6) : The effect is to create aspray which avoids stagnation of the runoff water. As a variation, installation on wooden frames equipped with joint-cover spine is possible if it is in conformity with CSTB worksheet n°. 3316 dated February 2001 and the modification no.3422.The choice of the fixing method must be made inaccordance with the regulations presented in CSTB worksheet n°. 1661 dated July/August 1980. In case of installation with insulation from outside, an air space of at least 2,0 cm must be left between the back of the Maestral® and the insulation in order to permit free air circulation. It is important to leave a vertical joint of approximately 1 to 1,5 cm between the central post of the mounting structure and the Maestral® Ω -shaped rail projects beyond the Maestral® facing
