"We live in an ecological and sustainable when it is this excellent insulation from heat and cold, which can reduce fuel consumption, saving money and energy to the inhabitants of the house. This is how we ensure a low environmental impact while delivering a comfortable environment and healthy: For over 30 years, the thermal coat proved to be the solution most used, most can be easily amortized in cost and more effective compliance with increasingly stringent energy requirements imposed by regulations, "This is the position of Cortexa, Consortium for the culture of the insulation system, just born with the aim of highlighting the importance and potential of this fundamental solution construction. It is well known fact that the first step in making a building envelope are not only efficient facilities at its disposal, although the latest generation and able to cover the areas of solar, photovoltaic or geothermal; without proper insulation, the energy produced by these systems would be dissipated unreasonably, defeating the significant investments required for their installation.
The construction market offers many solutions for building insulation, spacing between individual panels can dab needs delimited, or more complex projects, able to give solutions to the entire building envelope. This is the case of the thermal coat, solution whose name is evocative: the building is protected using a real coat, consisting of a succession of elements and ad hoc materials. The insulation system is used as a solution applied from the outside, the new façades or subject to major renovations, and is designed to optimize the thermal performance of the building, especially solving the long standing problem of thermal bridges, of those points , ie, in which the discontinuity constructive, resulting heterogeneity of building materials or to specific geometries of the project, interrupts the casing favoring the dispersion of heat in winter or air conditioning in the summer. Simplistically, the insulation is the application over the entire outer surface of the vertical wall covering, covered by a thickness of finishing and consists of a succession of products, including the insulating panels, the adhesive mortar for their fastening , heat insulation materials, mortar and reinforcement nets, plasters and coatings, fixing elements and products for sealing the joints.
A thermal coat designed in a workmanlike manages to transform a building envelope consumes energy in a home where passive, ie, it is not even necessary the presence of heating or cooling, because the thermal behavior of the environment is constant and is given by sum of the contributions mainly related to solar radiation. A good thermal insulation, therefore, guarantees the savings of resources, with positive effects on both the environmental balance, because it contains the use of fossil fuels, both on the bills, because in less use of heating systems is a clear cost savings. Some numbers: the presence of a thermal coat is able to reduce the bills of at least 45% and the economic investment required for installation of a thermal insulation is therefore depreciable in 3/5 years (source Cortexa). Last but not least, proper insulation is a guarantee of living comfort, thermal comfort, become indispensable ally in the fight against indoor air pollution. In detail, a comfortable environment can be defined when the internal air temperature is very similar to that of the internal surfaces, the use of an exterior insulation system favors this behavior, because the panels placed on prospectuses behave not only as insulators , but also as a filter, and the temperature that comes to the interior is already mediated by the transition layer. These features are not only important for the health of the whole, but also because the use of building technologies allow isolation related to the property to achieve the highest energy certification classes, including both the mandatory and voluntary, and will increase, therefore, the value of the real estate market, as well as align them with the most advanced European standards.
A further advantage of great interest both for architects to clients, is that operating on the outer surfaces, the layers in addition do not subtract residential area and allow you to take advantage of the maximum square footage available.
Inside the "Handbook for the application of the system Coat", created in collaboration with EAE (European Association for ETICS, External Thermal Insulation Composite System, www.ea-etics.eu), we highlight the main cornerstones for the installation of the system.
To follow, the sequence of stages:
- Preparation of the foundation, from cleaning to consolidation;
- Application of the mortar bonding the panels with distribution techniques "perimeter point";
- Laying the insulation boards from the bottom up and staggered joints with the aim of eliminating thermal bridges;
- Choosing the type of piece;
- Preparation of the construction details using edge protectors or ad hoc profiles and avoiding the use of elements in galvanized and pre-painted;
- Application of the mortar of armor on the entire surface of the insulating slabs of a thickness adequate to accommodate the reinforcing mesh;
- Application of the finish coat can protect the entire system and, at the same time, requirements and architectural style.
The market currently offers several product lines for the creation of a proper thermal insulation, ranging between both materials related to traditional building, both among new proposals green, a fast-growing sector, where the proposals include solutions based exclusively on biological materials , with certification for both the product linked to the production chain. One advantage that, coming to work alongside techniques already linked to environmental sustainability, further increase the value of the whole and reach the highest levels of eco-compatibility, allowing the individual project to obtain, for example, the certification KlimaHouse Nature, recently introduced and designed to assess and certify a building not only from the point of view of verification efficiency but also impacts on the environment and human health.
This certification, in fact, introduces a sull'ecocompatibilità evaluation of materials and systems used in the construction, based on objective scientific criteria and transparent.
