Through the Directorate of Urban Development and ecology, the citizens are invited to carry out the use of various thermal insulators in their homes, thanks to the potential of improvement in energy efficiency and the saving of electrical energy that can suppose the use of these Isolates up to 60 percent less.
Among the recommended materials is cellulose, ecological insulator that elaborates with recycled newsprint that conserves the heat and isolates the sound, the mineral wool, also known rock wool is used as insulator and passive protection against the fire, They also recommend the use of expanded polystyrene, which has great resistance to compression, is light and has good thermal protection.
Products of PVC and polycarbonates (PC) of second generation because of their composition are not affected by the UV rays providing an economic benefit thanks to its physical, mechanical and thermal properties. They are designed to have a better thermal comfort and with this achieve savings of electric energy by heating. The advantage over traditional metal sheets is that, by very good coating or paint, ends rotting away, besides being very hot.
Compared to the fiberglass sheets, these are degraded by the action of UV rays, in less than a year they begin to yellow and surface the fiberglass as a sign that they already lost their properties, besides being highly flammable.
It prevents thermal inversion, which means that in greenhouses there is always an internal temperature higher than that given outside.
Its high surface area index in relation to its weight, it traps air between blocks and that allows it to have low thermal conductivity, they get more efficiency than other materials, its use is very widespread in the construction as thermal insulating, acoustic and filling to streamline the conditioning system.
The implementation of some of the above-mentioned materials in households not only implies energy savings, but also economic savings, inner comfort and contributes to the reduction of 30% of carbon dioxide emissions in households.
