5.Base-coat plaster and reinforcing mesh
Coating insulation is a wide-spread system for external insulation. In recent years it has become an increasingly adopted solution, especially in cases of vertical external façades renovation. The insulation panels are placed on the outside and covered by reinforced plaster and mesh so as to increase the durability of the structure. External insulation has several advantages. Firstly, it guarantees the presence of a continuous layer of insulation, ensuring the elimination of thermal bridges, secondly it protects the structures from temperature fluctuations improving their durability. At the same time, the structure’s mass, which in this case is concentrated inside, allows to exploit thermal inertia. This way, walls cool down and heat up more slowly.
The supporting masonry must be homogeneous and leveled, without imperfections above the centimetre, cleaned of any residues and dry. The insulation panels must be fixed to the structure with a normal adhesive
mortar, which is laid on a continuous curb along the perimeter of the panel and on its central point. The panels must then be mechanically fixed to the masonry by means of coat plugs, in reason of at least four points (near the edges of the panel), we recommend to follow the specifications described by the UNI EN 11442 standard. The first layer of screed is applied, in which a fibreglass mesh with reinforcement function is drowned. After removing any imperfections from the mesh, all other protective layers are applied including the external finish, generally consisting of mineral- based paint.
SUPERCEL VITRUM is the ideal material for this type of application.
SUPERCEL VITRUM can also offer high fire resistance. It is covered with a saturated glass tissue on both sides, which, in application, brings the panel in class B s1, d0.
In cavity insulation of external perimetric walls.
3.External non-loadbearing masonry
The thermal performance of an insulated wall is further enhanced by the creation of ventilated air cavities. The circulation of air between the external and internal walls - to which the insulation panels are fixed, maintains a low concentration of water vapour and protects the panel over time.
Usually, they are non-bearing walls, but they can also be bearing ones, depending on the project. The exterior face, often performed in masonry (solid bricks), protects the bearing internal wall and preserves the interlaid thermal insulation, given that both remain inaccessible to weather changes.
If the external masonry wall is constructed simultaneously with the installation of the insulation panels, the mechanical fixing of the panels is not necessary: it will be sufficient to lay them on the wall in
overlapped rows and with staggered joints. The panels must be placed adjacent to one another in order to create a homogeneous layer that avoids the creation of thermal bridges. In the case of buildings with a bearing structure and perimeter walls, the problem of thermal bridges is solved by covering the pillars from the outside with the insulation panels.
SUPERCEL ALUMEN already has a coating that acts as a vapour barrier and is the ideal solution for the insulation of perimeter cavity walls. Alternatively, insulation panels that can guarantee a simple vapour screen, are those presenting a breathable coating, such as SUPERCEL VITRUM or SUPERCEL FLAMMA.

5.External cladding system for ventilated façade
The ventilated façade is characterized by the presence of a continuous ventilated chamber interposed between the external vestment - which can be made up of a wide range of materials - and the internal vestment to which the insulation panel is attached.
Thanks to the many advantages it entails, the ventilated façade is an insulation system which is being used with increasing frequency. The air chamber ensures the disposal of water vapour, avoiding condensation and thus the creation of humidity and mildew. The external facing vestment protects the insulating slabs from UV rays and bad weather.
The research and technology of building materials have led to high-quality systems, techniques and finishes that guarantee both high thermal insulation performance and aesthetics of the buildings. On the inner-facing wall or on the supporting wall, usually composed of masonry in brick or concrete, anchors, with the role of supporting the structure of the façade, are fixed. This system consists of a scaffolding of vertical and horizontal profiles: after having positioned the profiles, the insulation panels are laid and fixed mechanically to the supporting wall. This way, a ventilated air chamber of about 3 cm in thickness is created between the insulating mantle and the external vestment. The last step sees the installation of the façade finish, which is fixed to the structure of profiles that make up the anchorage system, usually in ceramic tiles or plates, natural stone, metal or other.
SUPERCEL FLAMMA, thanks to the excellent fire-reaction performance, which place it in the
B s1, d0 class, is particularly suitable for the thermal insulation of ventilated façades, especially in buildings that must be tested for the prevention of fires.SUPERCEL VITRUM, are also recommended, as they offer excellent vapour permeability. SUPERCEL ALUMEN is preferable when you want to install a panel that has a vapour barrier.
Internal insulation of walls.

5.Microperforated tape for joint reinforcement
The insulation of walls from the inside guarantees thermal efficiency of buildings without the need to resort to expensive interventions on the structures or façades. It is a highly used system in case of building renovations or in those instances where the objective is to increase the comfort and energy performance of a single house unit. In addition, internal insulation systems represent a good energy solution for all the environments occupied in a discontinuous manner, such as offices, commercial premises, second homes and in all those situations where there is a need to bring the indoor environment to the desired temperature.
SUPERCEL VITRUM is the ideal solution for this type of application. Thanks to the high insulation efficacy, they allow to reach the required thermal resistance with considerably thinner thicknesses than those needed for other materials. SUPERCEL ALUMEN are also valid alternative.
In this type of application insulation panels can be glued and fixed directly to the internal perimeter wall. When laying, the joints are to be sealed with reinforcing mesh belts. When fixing SUPERCEL BUILDINGpanels with mortars, cementitious adhesives or polyurethane foams, it is recommended to adhere to the instructions and laying protocols provided by the adhesive manufacturer. Also, it is good practice to pay attention to the alignment of the panels and to prevent the adhesive or grout from penetrating the joints. Then proceed to the final painting.
