Ventilated facades

NEXION – TERRAMILANO SOLUTION

Italian Engineering


Nexion – Terramilano offers a complete solution for ventilated façades thanks to the partnership between Nexion and Terramilano Engineering, one of the best Italian companies in the sector, with 25 years of experience with notable works as Torre Solaria and Bosco Verticale, Milano.

Definition

In compliance with the UNI 11018 standard, the ventilated facade is “a type of advanced-display facade, in which the gap between the cladding and the building is designed so that the present air can float by the stack effect, in a natural or artificially controlled way, based on the season and /or daily needs, in order to upgrade its overall thermo energetic performances”. Therefore, the ventilated facade is a cantilevered system giving the building a new skin.
FOR ALL ARCHITECTURAL NEEDS

Anchor systems


Nexion Hidden System

Hydden system

RECOMMENDED FROM RESIDENTIAL TO HIGH RISE BUILDINGS

The “Hidden System” is the only full elastic mechanical and most elegant solution for ceramic because it allows to hide the fixing hooks between the slabs and the sub-structure.

Nexion/ Terramilano Hidden System allows you to hide the hook that anchor the slabs to the structure.To achieve this type of fixing, it is necessary to make a milling slots (kerf) on the tile (specific engravings on the upper and lower edges) that serve as housing for the hook.

This machining is accomplished through a numerical control machine (CNC) to ensure maximum accuracy.

Nexion Hidden System

Slabs are anchored to the vertical stand by means of the S10 hooks. These are connected to the vertical stand not by using screws, which would make the system rigid, but rather they are hammered and are housed in the grooves present in the wings of the upright.

This allows you to obtain an elastic system, able to dissipate small deformations without compromising the stability of the façade.
This system allows unbeatable performance in terms of windload, fireproof, and systemic risk

Key features

  • SAFER USE IN AREAS WITH HIGH SEISMIC RISK

    – Elastic hooks allow better separation between primary (building) and secondary (facade) structure.
    – Use of fasteners (primary–secondary structure interface) designed for use in seismic areas.
    – Higher resistance to seismic force compared to rigid fixing of cladding panels.

  • LOW DEAD LOAD REQUIREMENT

    – Fully mechanical system (non flammable adhesive used for anti-vibration purpose only).

    -Use of non flammable cladding panels (e.g. ceramics).

  • VERY HIGH WIND LOAD RESISTANCE

    – High wind load resistance achieved in software simulation (not allowing elastic anchoring of panels).

    – Very high wind load resistance achieved in laboratory tests (above 6200 Pa with ceramic cladding panels of 9 mm thickness).

    AN UNBEATABLE SOLUTION

    Benefits


    • Waterproof

      Waterproof

      The ventilated air cavity built into the system means that rainwater does not penetrate through to the inside of the cavity. It keeps the skin of the existing building healthy in the wintertime.

    • Safety in use

      Hides the building’s services. The ventilated facade camouflages the building’s electrical, gas or plumbing installations, but at the same time allows easy access to them.

    • Durability

      Ceramic is extremely resistant and has great durability. Its resistance to acid corrosion and ultraviolet rays means that its aesthetic appearance remains unaltered over time.

    • Energy savings

      Ventilated air cavity enhances thermoregulation and helps make buildings more energy efficient. It reduces air conditioning and heating consumption by around 30%.

    • Aesthetic value

      The different formats available and the wide range of designs, colors and textures make the ventilated facade system even more attractive.

    • Easy to install

      The lightness of the pieces, specially designed to reduce their weight, is a great advantage. Also, if a piece gets damaged or needs replacing the system is very easy to repair.

      Six more reasons

      Why you shoud prefer ventilated facade


      • Thermal insulation

        A reduction in the amount of heat that buildings absorb from the partial reflection of solar radiation by the outside facade, and the naturally ventilated air cavity. In cold weather conditions ventilated walls retain heat.

      • Acoustic insulation

        The air cavity acts as further acoustic insulation from the outside, reducing noise by between 10% and 20%. A reduction of this level can greatly improve occupant comfort.

      • Breathability

        The air chambers and the dry installation system facilitates the breathability of the brickwork, making the air in the interior spaces more healthy and preventing mold and humidity.

      • Protection against vibration

        The expansion joint allows the vibrations to be absorbed and makes the system seismic resistant. The air gap between the tiles prevents damage due to collision.

      • Green Building Standards

        Exterior cladding, and in particular facades, assume a critical role from the point of view of sustainability enabling a reduction of energy and an increase in thermal comfort.

      • Restructuring

        Ventilated facades are particularly suitable and valued in building renovation, It’s application enables some utilities to be transferred to the exterior of the building, simplifying monitoring and maintenance.
