How is the ventilated wall structured?
The ventilated wall is a wall made of perimeter walls of the structure to which an insulating system is applied which does not remain in contact with the masonry but which creates an air space in which air can circulate. The air recirculation that is created within this space is called “fireplace effect” and serves both in the hot and cold periods, with the aim of improving the thermal performance of the building. The purpose of this air recirculation is to remove moisture and water vapor, but also the heat that builds up, protecting the masonry from infiltration and ensuring greater thermal insulation.
This type of insulation is made up of three technical layers interconnected by each other: from the inside we observe the perimeter masonry to which is applied an insulating layer consisting of semi-rigid panels glued or fixed with dowels to prevent thermal bridges; an air gap between two to four inches, and an exterior insulation exterior finishing.
Modul 25 Centrometal offers a ventilated sliding roof system with recessed fixing, suitable for wall covering, in the upgrading of old buildings. The characteristic mounting system uses a structure able to support all possible expansion of the metal coating and creates an air gap that ensures the natural circulation of the air and the possibility of inserting a layer of thermal insulation.
Which materials do you use?
The layers that characterize a ventilated wall are:
1. Wall: is the existing structure brick, in contact with the outside
2. Insulating layer: this is applied with glues and dowels to insulate the wall and use coat insulation materials to limit thermal dispersions to the outside and slow down the passage of heat, especially at the major points necessity, such as those at beams and pylons, junction between the floor, where the thermal bridges are greater.
3. Fireplace: This is the cavity that is used to remove water vapor that stops inside, remove surface heat from the walls during the summer, act as insulation in the winter period and mitigate the thermal flow.
4. Carrying structure: metal support with aluminum fastening system, as the best material to withstand stresses and degradations from external environment, limited weight, and high corrosion resistance. Expansion joints are “attacks” that serve to regulate retreats and expansions of the metal with hot and cold.
5. Sheets for the outer coating: generally made of porcelain or porcelain stoneware, but also metal or composite materials can be used. The characteristics of this material are high mechanical resistance, thermal changes, water to chemicals and smog, unbeatability, lightness, workability and limited maintenance.

Ventilated wall, improve the quality of home life: The advantages of the ventilated wall
The advantages of installing a ventilated wall are really many and basically concern the ability to reach very high standards of building energy efficiency, with added acoustic comfort, and also the architectural value of the system that this technology possesses. In addition, the ease of setting up of the entire system and its easy integration with the facilities make it easier to prefer than other systems in use.
