Thermal insulation with nanotechnological materials


THEnanotechnological materialsguarantee the maximumthermal insulation(and also acoustic) in small spaces. L'thermal insulation with nanotechnological materialsit is recommended when neededinsulate housewith a thermal coatwith reduced thickness.

Architectural constraints or space requirements sometimes prevent the installation of athermal coattraditional. It is in this context that materials come in handy which, in a very small thickness, can offer excellent insulating properties both from a thermal and acoustic point of view.

Those who have no space constraints can create a layerheat-insulatingwith cellulose fiber or other insulating materials, while those who must respect certain architectural restrictions of thickness will be able to evaluate the realization of athermal coatthrough thesenanomaterials.

Among the various products on the market we point out the panelsAeropanwhich in just 10 mm of thickness offer a thermal conductivity λ 0.013 W / (mk). These panels are intended forthermal insulationthanks to a nano-porous flexible insulating coating capable of eliminating thermal dispersions. What material is it? Amorphous silica gel with reinforced fibers.

Insulating panels made of amorphous silica gel and reinforced fibers are more effective than other materialsheat-insulatingsuch as polyiso foam, styrene foam, glass wool, fiberglass or blown cellulose. In addition, these insulating panels, in addition to being hydrophobic (excellent for containing the problem of rising damp) are also breathable, offering a good solution to the problem of condensation in the home.

With the evolution of the sector ofgreen building, the market has begun to offer technologically advanced materials with very high insulating performance. Among these we also point out the panelscomposed of micronized cells of silica oxide-based powderssuch as Vacunanex sheets, vacuum packed to guarantee higher insulating capacities in less space: a 10 mm sheet of Vacunanex offers superior insulating performance than a polystyrene sheet of 80 mm.

Vacuum insulating panels represent a great progress in the field ofthermal insulation as their conductivity is 10 times lower than that of the best conventional insulating materials; this feature allows a considerable reduction in thickness.

The thermal conductivity of the insulating sheets made of micronized cells of silica oxide-based powders is equal to 0.02 w / m ° K with an insulating capacity equal to λ = 0.005 W / mK.

For finishing a thermal coat it is recommended to use a thermo plaster capable of assisting the actioninsulatingof the newly installed panels.
