Mineral wool
Saint-Gobain ISOVER uses natural and abundant raw materials (sand or volcanic rock), using fusion and fiberising techniques to produce glasswool or stonewool. The products obtained come in the form of a "mineral wool mat" consisting of a soft, airy structure
Reaction to water and humidity
Depending on its destination and purpose, mineral wool can receive appropriate treatment to obtain a specific behaviour to water.
For its application in buildings, mineral wool is classified as non-hydrophilic in order to satisfy various applications: insulation of walls, facings, lofts, partitions and humid rooms (bathrooms, kitchens).
In the event of accidental wetting, mineral wool regains its thermo-acoustic properties after natural drying. It is naturally non-hygroscopic as it does not absorb humidity in the air.
Vapour transfer and condensation
Thermal insulation of walls must resist flows of vapour that may cross them. That is why certain products are fitted with a vapour barrier: placed on the heated side of the wall, it prevents risks of condensation.
