Architectural Envelopes

Architectural Envelopes

Envelope refers to building elements which both connect and separate the "inside" and "outside" of a residential building. It establishes a relationship between the building and its environment, an authentic architectural and construction filter, in turn creating relations between the people who live in a building and the surrounding environment.

Architectural envelopes have always represented a privileged yet highly complex field of innovation. The continuous research into special, advanced forms and technologies, the increasingly pressing need for customisation and the fact of acting as the building's calling card in its environmental and social context, have always made this an extraordinarily important part of a building, and with it the materials and construction systems used to create it.

The current function of building envelopes as filters also supports the dynamic control of energy exchanges that constantly take place
between the inside and outside, making the envelope a dynamic interface that interacts continuously with the external environmental and climatic factors, an authentic skin, which together with its construction systems is responsible for optimising the internal comfort of the building and maximising its performance requirements. In this scenario, therefore, the efficiency of a building envelope lies in its ability to react flexibly to the continuously varying environmental conditions, minimising heat dispersion in winter and excessive heat gain in summer.

Currently this aspect is of particular relevance, given the growing focus on energy saving and residential comfort, issues which are increasingly attracting the attention of architects and designers, investors and builders, as well as customers and end users. The technological and architectural solutions demanded today by the market therefore strive not only for architectural quality, but also energy efficiency, with the possibility to blend quality and functionality in a single building envelope that controls both the energy behaviour of the building and its appearance.

A building envelope, as a construction element, is composed of vertical elements (walls and windows) and horizontal elements (floors and roofs): the set of these components creates the perimeter of the living space. In this technical catalogue, we deal in particular with façade covering systems used to create building envelopes using Ultra slabs.

WET ENVELOPES

Safety Clip System

Dry application of Ultra slabs directly onto the existing wall by gluing, a layer of suitable glue is spread over 100% of the laying surface, chosen according to:

- Laying base, support on which the slab is applied, with
suitably resistant features.
- Adhesion and tearing strength
- Material size
- Façade composition
- Climatic and environmental conditions

Thermal Cladding System

Ultra slabs are laid on a thermal cladding system to ensure appropriate thermal comfort inside the building, through the application of a specific system requiring a mechanically resistant support made of a series of layers applied to the brickwork:

- Plaster
- Insulating layer
- Reinforced plaster
- Porcelain stoneware slab

DRY ENVELOPES

Micro System

The Micro system uses an adhesive to apply the porcelain stoneware slabs to the building façade. It comprises a permanent, highly elastic adhesive and a double-sided adhesive assembly tape; the base support is firstly treated and then the slab is fixed to the façade with this invisible system. The system includes a metal under-frame fitted to the wall or on top of the thermal cladding, which ensures the ventilation behind the panels.

Ventilated Facade

The ventilated façade system involves the assembly of the
covering elements (Ultra slabs) onto aluminium load-bearing elements using factory-mounted structural joints. Two sub-families of this system have been developed. While they share the frame-slab assembly using structural joints, they have different types of structures to anchor the Ultra slabs to the wall:

-Ultra Frame:

which uses a load-bearing perimeter frame hung on modular brackets anchored to the wall.

-Ultra Light:

a system of vertical shaped profiles fixed to a traditional grid of uprights and cross-beams fixed to the wall.
