Rock wool and mineral wool, specific insulation for humidity

Rock wool and mineral wool, specific insulation for humidity


Water-repellent and non-hydrophilic solutions for your facade


Rock wool and mineral wool are insulations that act as a barrier against moisture . They are water-repellent solutions , they do not waterproof the facades (they are fibrous and porous materials) nor do they prevent leaks , but they are non-hydrophilic solutions, that is, they do not have an affinity for water, and they are not hygroscopic.


Despite the fact that there are leaks or condensation that generate large amounts of water or humidity or water vapor, mineral or rock wool will not absorb it, nor will they trap it from the environment in in any case, since its classification against humidity is < mu1 (that is, 

in 1 m3 they may contain less than 1 liter of water), an extremely easy quantity to quickly evaporate or be eliminated by the material.


Lana mineral

Mineral wools are products of mineral origin in the production of which minerals have been used, that is, basaltic rocks in the case of rock wool, and silica sand in the case of glass mineral wool. They are internationally recognized as acoustic insulators, due to their flexible structure, and thermal, due to their interlacing that keeps the air immobile, and they are also non-combustible, due to their inorganic origin.


Many of the damage that occurs in a construction are caused by the harmful action of humidity . When humidity is introduced into a building, it causes different problems such as: decrease in thermal protection, degradation of materials, appearance of mold and fungi, etc.


If your façade generates condensation and humidity problems, including mold, you need materials with characteristics of good behavior against water; materials such as cellulose or wood fiber are not recommended; 


The only materials that will guarantee the quality of the blown insulation in these cases are rock wool and mineral wool. The same occurs in homes in very humid or cold climates, in mountainous areas or with high rainfall or high humidity, such as the Pyrenees or the 


Basque Country, in which case it is also advisable to insulate the facade with mineral wool or rock wool.

We must also point out that in Spain many facades with an air chamber, made of exposed brick or cement plaster, are non-waterproof facades, so injecting materials with the capacity to absorb humidity or similar is crazy and will cause many problems in the future. The option for them is mineral wool (supafil product) or rock wool (rockwool product).


Mineral wool is water repellent and not hydrophilic. Hydrophilic (from the Greek hydros "water" and philia "friendship") is the behavior of any molecule that has an affinity for water . In a solution or colloid, hydrophilic particles tend to approach and maintain contact 

with water. Hydrophilic molecules are in turn lipophobic, that is, they have no affinity for lipids or fats and do not mix with them.


Lana of rock or blot

Rock wool is the insulation obtained from the spinning process by heating volcanic basaltic rocks and mineral coke, up to 1500 degrees 


Celsius ; in the liquid state, "threads" are obtained, which, when stretched and cooled, intertwine to obtain raw rock wool. The eraser is the material that we use without processing and it is the only version or format for blowing. They cannot be considered natural, nor a recyclable material, but 95% of the raw material is natural (basalt)


Lana mineral

Mineral wool is the insulation obtained from the mineral silica; In the case of mineral wool, it is obtained from glass recycling (transformed silica), heating up to 1600 degrees Celsius; in liquid state thread-fibers are obtained, which are intertwined obtaining mineral wool in bulk or fluff. The eraser is the material that we use without processing and it is the only version or even format blown. It cannot be considered a natural material, but it is recyclable and respectful of the environment.
