Thermal insulation, the materials of efficiency


A goodthermal insulationcan improve the energy efficiency of buildings. Among the proposals of the market existthermal insulatorsmade with strictly eco-compatible and natural materials,thermal insulatorswhich exploit the low conductivity of air and some gases, and again, real onesthermal insulation systems. Those who are planning an eco-friendly home may find this small list of some of thethermal insulatorsmost popular on the market.

Duo Concept
The name is due to its structure: two rock wool panels, spaced apart by a corrugated aluminum plate that form a ventilated cavity. The passage of air not only guarantees excellent resultsthermal insulation,it also manages to prevent the formation of mold and humidity. The material manages to guarantee a goodsoundproofingisthermalof the building especially when the insulating, transpiring and protective capabilities of theDuo Conceptthey are enhanced with exterior finishes based on mortar and plaster.

NaturalWall
A plasterable wood fiber thermal insulation panel that combines heat and cold insulating performance with breathability to prevent mold and soundproofing. Naturalwall can boast the European ETA certification, an excellent solution for thermal insulation systems.

Face Work
Those who prefer a tile and stone roof must not give up thethermal insulation. Face Work combinesthermal insulationexternal insulation with tile or stone finishes.

Mapetherm
System ofexternal insulationwhich provides for the application of thermal insulation panels with a glass fiber reinforcement mesh interposed on the subsequent smoothing.

THEmaterialsused for the production ofthermal insulatorsare varied, we are talking about cork, simple or mineralized wood wool, wood fiber, glass wool, rock wool, expanded polystyrene, extruded polystyrene, expanded polyurethane ...thermal insulationof a building is not just about ceiling and wall, the fixtures play a crucial role, that's why there are double-glazed windows.

When it comes tothermal insulationthe so-called "U factor ". The U factor represents the thermal transmittance which expresses the amount of heat that in the unit of time can pass through a surface element of 1 square meter in the presence of a temperature difference of one degree between the inside and the outside. In other words, in Factor U it represents the complex of thermal exchanges between the external surface of a wall and the internal one. Plus theU factorof a material is high, the less suitable that material will be for construction use, on the contrary, the lower the U value and the greater itsthermal insulation.

With double glazing the U value decreases drastically: a double glazing consists of two sheets with an interposed cavity filled with dry air. Double glazing exploits the low thermal conductivity of the air forhouse insulation.
