The rockwool is part of mineral materials of insulation used effectively to reduce the energy expenditure of a house. Obtained starting from the synthesis of rocks, it is a material available in great quantity just like the glass wool. The rockwool has a lot of significant advantages for a éco construction.
Characteristics of rockwool
The rockwool is obtained by the fusion and the fiber drawing of basalt, a volcanic rock. Basalt molten then is liquefied in order to form a tangled up wool mattress. This intermingled aspect makes it possible rockwool to better retain the air. The substance thus obtained is distributed in the form of rollers or of smooth and rigid panels or shells or of flakes for a mechanical or manual spreading.
Within the framework of an optimal insulation, it is preferable to use it in its shape of panel more rigid than in the form of rollers and where the wool is of low density.
The raw material for its manufacturing is available in quantity and answers the current ecological questions completely.
The manufacturing process of glass wool is almost identical to that referred to above. They are both of materials at mineral base. The glass wool is elaborate starting from sand rich in silicon oxide.
However, one deals with substances rather sensible to moisture. This weakness decreases the power isolating from those, from where the presence justified of vapor barriers on the rollers.
Advantages and disadvantages of rockwool
The rockwool is natural elements relatively simple to manufacture. It is thus a material economically advantageous with prices which vary from 3 to 6 euros the m ² and according to the thickness and the type of selected forms.
In addition to an economic price being able to direct your choice, the rockwool also offers a certain number of advantages to the level of the insulation from its properties.
The rockwool constitutes a means of thermal isolation concluding thanks to the presence from bubbles of air concentrated in its structure. In the same way, the fitting of the fibers which composes it makes it possible to dissipate sound energy naturally.
It also has as an advantage of the fireproof characteristics. It largely improves the capacities of fire resistance of constructions. Particularly adapted to the elements which must guarantee of a strong mechanical resistance such as the roofs, the choice to install rockwool proves to be an effective solution.
However, will know to it the handling of this fiber must be the object of some care. The rockwool would present a carcinogenic threat indeed. Even if they were reclassified in group 3 of the carcinogenic substances in 2001, i.e. less dangerous than asbestos, it is necessary to be careful as for its installation. The character bird of material makes that it can be introduced by the tracts respiratory and affected of the bodies such as the lungs.
Thus, the use of cutting tools at slow speed, of means of protection of the body gloves masks and glasses and finally to prefer the use of a high efficiency filter vacuum cleaner or of more detergent water, are strongly recommended. |
