    Do you know glass wool?

    La fiberglass it is an amorphous silicate obtained from glass and is a very versatile material, mainly used in construction and in the silencers of endothermic motor vehicles.

    Its production process is very simple.

    The raw materials are chosen which for 80% are made up of recycled glass, to which silica (sand), limestone, sodium carbonate, boron are added, and the whole is transformed into powder.

    To these natural materials are added some components that optimize the qualities of the final product.

    The mixture is placed in a heated oven and melts at a temperature of 1.450 ° C.

    The magma reaches the manufacturing units and here the real fibers are produced by passing through the holes of a rotating hood.

    We proceed with a first horizontal mechanical stretching, then the fibers are stretched vertically and finally they are dressed with particular resins and positioned on conveyor belts.

    They then pass into hot air ovens (about 250 ° C) where the polymerization of the resins takes place.
    The running speed on the belts and the spacing in the stove allow you to adjust the density and thickness of the products.

    We arrive at the final stage with the coupling with any coating supports, cutting, finishing and packaging.

    La fiberglass due to its natural characteristics it is excellent as thermal insulator and allows great energy savings, easy to use and above all respects the environment.

    The advantages of glass wool are:

    It is a environmentally friendly material almost entirely produced (90%) with inorganic raw materials (silica sand) available in nature in infinite quantities.

    Ha excellent thermal and acoustic insulation characteristics: as it is a porous material with open cells.

    Prevents acoustic transmission from one room to another, decreases the amplitude of acoustic vibrations, reduces the intensity of sound transmission.

    Resists water and humidity: glass wool, even if soaked in water, once dried, regains its thermal, acoustic and mechanical characteristics.

    It is a safe material in the event of a fire, glass wool is recognized as not combustible and does not give off toxic fumes.

    Has a excellent cost / performance ratio thermal: with the same thermal-acoustic performance, it has a lower cost than other insulators. And it is highly durable over time, is an inorganic material for over 95% and for this reason it guarantees the inalterability over time of its thermal, acoustic and mechanical characteristics.
