From the point of view of their construction, Marazzi Engineering ventilated walls have three types of components:

  • The thermal insulation next to the outer walls made of a insulating, water-repellent material;
  • An aluminium substructure secured to the building with brackets that is covered and shaped in different ways depending on the anchoring system;
  • The outside covering, fitted with open joints;

There is a wide range of accessories in addition to these basic components, designed to answer any need in terms of the desired look or for planning constraints.

THERMAL INSULATION
The insulating panels are placed on the outside face of the perimeter wall to form a continuous layer. They have been specially developed for ventilated facade systems and are made of materials with different specifications and characteristics:

  • Mineral wool
  • Polymers
  • Natural materials

ANCHORING SYSTEMS IN SUPPORT OF THE ALUMINIUM SUBSTRUCTURE
Marazzi Engineerings suggests different kinds of anchoring systems:

The Exposed Hooks System (A.G.V System)
The first ever system launched by Marazzi remains a very popular choice because of its simplicity and affordability. The parts of the outer face are supported by stainless steel hooks. The A.G.V. system can be used for either flat or vertical surfaces and even for sloping or curving (polygon) surfaces. The standard plate sizes used are 60x120 cm, 60x60 cm and 30x60 cm, all of which can be squared. Other sizes can also be used made by cutting standard sizes.

The Concealed Hooks System (A.G.S. System)
This system was the next step in the development of the ventilated facade and is an ideal solution when the intended final appearance of the facing requires as few technical constraints as possible. The plate is hooked onto the load-bearing substructure, connected to the outside wall of the building with aluminium angular brackets. The extreme simplicity of the A.G.S. system can easily accommodate any kind of detail, including corners and door- and window frames. The compatible sizes are the same as for the A.G.V. system: 60x120 cm, 60x60 cm and 30x60 cm, again squared, and other sizes made by cutting.

The Modul Panel System.
This is a more innovative and cost-effective version of the A.G.S. system. The covering plates are pre-assembled onto panels by attaching metal shaped sections that are secured to the plates with special screw anchors. The assembled panel is then mounted onto the same substructure used for the A.G.S. system. By pre-assembling the plates onto the panels, this solution helps reduce the use of connecting materials, substructure parts , preparation time and finally the installation time on site. The Modul Panel was designed specifically for long, narrow sizes (30x120 cm, 30x90 cm), making them more cost-effective to use.

The Key Panel System.
This system was inspired by the same philosophy as the Modul Panel system, as the rectangular plates are pre-assembled vertically by attaching them to open horizontal sections using screw anchors. These are then hooked onto a substructure that is identical to the A.G.S. system. The affordability of the Key Panel system is down to the same considerations as the Modul Panel.

The Sika Tack® Panel System.
The covering plates are secured to the same type of substructure with vertical uprights as the A.G.V. system using a polyurethane adhesive. The main advantage of this system is the elimination of any mechanical fastening, so it becomes particularly affordable. It is extremely versatile and is compatible with the main materials used for outer facings: porcelain stoneware, fibre cement, aluminium and laminates.

COVERING PLATES
Marazzi Engineering has a wide range of materials for the outer face of its ventilated facade:

  • Porcelain stoneware
  • Marble, granite and natural stone
  • Terracotta
  • Extruded material

Until a few years ago, the standard size of porcelain stoneware plates for ventilated walls was 60x60 cm, a single shape that limited the creativity of designers because their only resort was the costly cutting of ceramic tiles whenever they wanted to use different modules. Marazzi uses some of the latest production technology in the industry and can offer designers a wide variety of ceramic sizes, such as 30x60 cm and 30x120 cm, right up to large sizes such as 60x120 cm. This opens the door to the most diverse textures and sophisticated architectural solutions, giving designers total flexibility.

ACCESSORIES
Marazzi Engineering can supply a wide range of fittings and accessories for ventilated walls, such fibreglass safety net, end sections for the horizontal joints in aluminum, micro-perforated aluminium grilles, to complete and customize the designer’s solutions.
