The blown mineral woolThe blowing technique is a method used for the insulation of attics lost of new houses or to renovate. The flakes of insulation clog up all the spaces that rollers would have difficulty covering.Its advantages: it reduces the transmission of airborne noise and shock, it is non-flammable, rot-proof, easy to handle and easy to install.. It comes in the form of rolls or panels and is used in the same way as glass wool.What insulation for what type of roof?Here is what we recommend, depending on the type of roof in your house. It requires the installation of a vapor barrier to regulate the indoor humidity.Its advantages: good insulation capacity, impermeability, very light material, high mechanical resistance, easy to work and good price.

　　It comes in bulk, panels or rolls and adapts very well to hollow spaces and inter-lodgings.Its disadvantages: synthetic material, poor acoustic performance, flammable, fragile, toxic release over time and in case of fire. Extruded polystyrene (XPS)Extruded polystyrene is also made from crude oil.Its disadvantages: slightly more flammable than other insulators.Its disadvantages: more expensive than expanded polystyrene. But it still delays fires because the cellulose is covered with carbon in contact with the flames, which has the effect of slowing the spread of fire and heat. It can also be used as foam for caulking joints.

　　In panels, it is used in screed insulation and outdoor.Its disadvantages: synthetic material, it can be toxic BBQ Gloves Suppliers in case of fire.Its advantages: it is an ecological material of a great longevity, with a very good thermal inertia and offering a very good acoustic insulation. Using a blowing machine (a carding machine) the mineral wool is projected into the roofs over the entire surface homogeneously, quickly and efficiently. Its manufacturing process consists in binding together a multitude of balls by compression during a molding that will trap the still dry air
