Does mineral wool absorb moisture?

It's hydrophobic, so it won't absorb water or encourage the growth of mold and mildew. Mineral wool is also very fire resistant and can act as a fire stop. However, like many building materials, mineral wool also has its drawbacks. It tends to be more expensive than fiberglass, often between 25-50% higher in cost .25 Sept 2019


Does mineral wool drain water?

Mineral Wool Insulation Isn't Like Fiberglass ...
Mineral wool, on the other hand, will not become wet. In fact, water beads up and rolls off the surface of mineral wool. This promotes water draining and drying if the wall cavity becomes wet, rather than holding water like a sponge.8 Apr 2014

You really are a brainless dolt, and the strange thing is that you insist upon displaying it again and again.

Your Google searches are correct in saying that these materials are hydrophobic, but you obviously didn't understand the rest . I'll try to explain it to you, but you probably won't understand most of that either.

The insulation properties of mineralwool/fibrewool do not rely on the properties of the fibres but the millions of tiny air-spaces created between the millions of inter-twined fibres. These air-spaces create the thermal insulation properties of the wool blankets.

In a situation where you have cold on one side of an insulating material and warm on the other side there is obviously a thermal gradient where the two meet and equalise in the middle. In this case the warmer side , air will carry more moisture because this is what physics decrees and at a certain temperature as it descends to align with the lower temperature it will pass through the Dew Point. As its name suggests the Dew Point is the temperature at which moisture suspended in air condenses into water.

In the case of mineral/fibrewool the Dew Point will obviously occur somewhere within the thickness of the insulation and this is called interstitial condensation ( told you , you wouldn't understand it ) and the condensation will then be held by friction between all the fibres: the fact that they don't absorb the water is irrelevant, friction and stasis will ensure that the water stays there. What is not irrelevant is that the thermal conductivity of the water destroys the insulation value ( R) of the material, and furthermore its weight will drag the wool into a sodden mess at the bottom of the wall.

Right, that's enough. No more time to spend conversing with this witless buffoon and I apologise for the deviation from the topic thread.

I saw a clip recently of somebody reversing his van through a ford.

Good move, as the bow wave was nowhere near the engine, and water level actually reduced round the front.
