Glass wool
Rockwool
Stone wool is most likely a fibrosing agent and carcinogen of the lung. Rock wool is not yet considered to be carcinogenic by the French authorities.
Let us not forget that it was not until 90 years after the first observations of health problems linked to asbestos to arrive at its total ban in France in 1997. European directive n ° 1999/77 / EEC of July 26, 1999 banned asbestos on January 1, 2005 in all European member states.
Glass wool
radioative?
Glass wool contains rock residues from the manufacture of ultra-transparent glass. But it is a natural radioactivity, of a very low level and therefore harmless to health!
During January, we learned that the company (......) had used radioactive sodium silicate for the manufacture of its branded glass wool (......). The product obtained had a level of radioactivity 4 to 5 times higher than that of traditional glass wool; this with the authorization of the Office for Protection against Ionizing Radiation
(Opri). (......) explains that the incriminated glass wools remain largely below the alert thresholds and therefore do not present any risks. The CRII-RAD (independent laboratory) considers that the risks are low, hardly greater than those of basic products, and that they do not make it necessary to remove these isolations; but it considers that this file raises fundamental questions: right to information of the consumer, unjustified character of
the deliberate addition of radioactivity and risk linked to the multiplication of this type of process!

When I was a kid in the canteen, a little chubby turned to me to
slip me a: Do you realize that you eat animals? It doesn't
don't give a bad conscience? With dread I had to admit that he had
right. I ate poor oxen that hadn't even been to me
presented, then, I gave up my steak and he ate it. I pulled a
moral of it all: The talkative talkers always get their way.
Why isolate
Insulations made from mineral fibers are the most common. Glass wool is obtained by melting, centrifuging and blowing recovered glass while the raw material of rock wool is usually basalt. Their insulating power greatly decreases in the presence of moisture (hence the presence of vapor barriers on the rollers).
Important: It is important to note that under the name glass wool or rock wool are classified products with a density ranging from 12 kg / m3 to 130 kg / m3. While their insulating power is more or less the same in winter, the lightest products do not protect you from the heat in summer. As to date no summer performance is required of insulation, it will be very difficult for you to obtain from your dealer or installer information on the weight of the insulation that he intends to provide you.
Be consistent in your choice of insulation: there is no point in having 20cm of insulation on the walls if you are using standard windows.
In the event of a noisy exterior area, provide exterior joinery with 8/8/4 double glazing instead of the standard 4/12/4 (figures indicating respectively the thickness of the exterior pane, the air gap and then the pane interior).
Still in this case, prefer windows or French windows opening in the French way to the bay windows.
You can also request exterior air intakes (mandatory) lined with a sound-absorbing coating. Likewise, avoid roller shutters with a protruding box on the inside.
In the case of terraced houses, if possible provide a party wall which is actually made up of 2 walls, one for each house, and separated by a minimum distance of 1 cm. If the walls touch each other, impact sounds will be easily transmitted from house to house.
In the case of adjoining houses, provide if possible an adjoining wall which is actually made up of 2 walls, one for each house, and separated by a minimum distance of 1 cm. If the walls are touching, impact noises will be easily transmitted from one house to another.
Between a weakly insulated house, the cost of heating can be divided by 3-4 times.
The cost of insulation is generally amortized between 3 and 5 years.
By reducing heat loss, the insulation prevents the phenomenon of cold walls, a source of condensation and discomfort.
Where to start.
Where heat loss is greatest: Uninsulated house.
Door and window 13%
Walls 18%
Roof 30%
Soil 16%
Air renewal 20%
Thermal bridge 5%

How to properly insulate.
The right thicknesses:
attic or high floors: 16 to 22 cm.
In walls: 6 to 8 cm.
On low floor or ground: 3 to 6 cm.

Lightweight and easy to handle, the coated IBR fits perfectly into traditional solutions. Techniques facilitating the installation of a paneling or plasterboard finish. Easy to cut and plug in, it provides perfect and economical insulation. Flexible, it adapts to all forms of framework and guarantees total sealing of the home without any parasitic drafts. Thermal comfort guaranteed.
A thermal bridge refers to any insulation defect that causes heat loss. Most often, thermal bridges are in the corners of walls and slabs of a home.

What thickness?
Insulation is allowed up to 15 kg/m2
Roof ventilation is necessary to eliminate any risk of condensation in winter, to remove air overheated by the sun in summer, and to ensure good conservation of the materials making up the roof.
The presence of a vapor barrier is particularly recommended in very cold areas or with airtight roofs or when the insulation is covered with a floor. A 200mm glass wool for the ceiling and the top.
Between the glass wool and the floor above, 8cm of air is sufficient!

Glass or rock wool does not spread fire or contribute to fueling the fire.
