Insulation: materials, deductions and efficiency


As seen in the articleHow to insulate the house,thereinsulationis a technique forisolate two systems having different environmental conditions, making sure that the two systems do not exchange heat (thermal insulation) or sound vibration (sound insulation).

In construction, the two systems are represented by the inside and outside of a home that have different temperatures and noise conditions. Thereinsulationcan offerthermal insulation, acoustic or, at the same time, thermoacoustic insulation.

Insulation and energy efficiency

Thereinsulationis a key practice for the realization of passive houses, energy houses or high energy efficiency houses. Good insulation is also a key element in green building and bioclimatic architecture where the designer's aim is to perfectly integrate a building structure into an environment, making it as energy self-sufficient as possible. A goodinsulationit allows you to save on heating in winter and air conditioning in summer, and also solves the problem of humidity and mold upstream.

Typically, the insulationit is performed by interposing between the two systems (inside and outside of a building) insulating materialscapable of limiting heat exchanges. With theinsulationwe talk aboutthermal coatwhich, for new buildings, becomes an intrinsic element of the building structure (right from the choice of starting materials) while for an existing building, thethermal coatit can be integrated with different types of intervention. Before proceeding to insulationof an existing building it is appropriate to make a thermography to understand the elements to be isolated with greater urgency. All the restructuring interventions that have theinsulationof a building, are entitled to the tax deductions provided for with the so-calledEco-bonus: learn more about Tax deductions on renovations.

Thereinsulationof buildings has made great strides in recent years, both in terms of diffusion (more and more people decide to install athermal coat,moreover, the concept of “green building”, also thanks to the diffusion of energy certification, is gradually expanding also in Italy), both in terms of thermal insulation materials. Among the latest proposals in the sector, there is no shortage of insulating materials that are able toinsulate housetaking advantage of very thin thicknesses, this is the case ofnanotechnological isoalnti materialsthat isolate by “stealing” only 5 mm of space.

Thereinsulationconcerns all the structural components of a building: from the floor to the ceiling, from the walls to the fixtures, indeed, the fixtures represent one of the critical points ofinsulation so much so that in this sector an ad hoc energy certification has been created (see: window certification).

Insulation, insulating materials

As stated, the list of thermal insulation products offered in green building is getting longer and longer. The materials used for thethermal insulationthey are characterized by low thermal conductivity. Among the most popular materials forinsulatea building, we mention polyurethane foam, rock wool, glass wool, synthetic rubber, expanded polystyrene, ceramic fiber, cork, cellulose fiber ... and many other materials characterized by an adequate thermal transmittance.
