Can rockwool insulation be left exposed?
One thought that comes to mind is to spray the rockwool with a clear-coat spraypaint sealer after it's installed, just to try to make a surface that binds the fibers together a little, but that's probably not compatible with the whole fire-rated ceiling theory.
Will mice nest in rockwool?
In this study, house mice caused significant (P < 0.01) increases in the thermal conductance of 10.2-cm thick wall panels, insulated with cellotex, fiberglass, rockwool, styrofoam, and vermiculite. House mice often tunnel and nest in insulation within wall spaces and ceilings.Mar 1, 1992

What are the disadvantages of Rockwool insulation?
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 . Because it is more unusual, it's not available in as wide a range of sizes as fiberglass and is almost never available in a paper-faced format.
Does Rockwool cause damp?
As compared to chemical products like polyurethane foam, rock wool insulation is a vapour permeable material. This means that damp can freely circulate and evaporate, so the risk of damp problems remains limited.
What are the advantage and disadvantages of using rock wool insulation?
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 .

- One layer of 3/4-in.
- 1/2-in.
- 1/4-in.
- Batts or blankets of mineral wool or fiberglass insulation secured in place.
- Cellulose insulation installed as tested for the specific application.
Does ROCKWOOL insulation need to be covered?
Note that rock-wool insulation only comes un-faced, meaning there's no kraft-paper or foil barrier. Depending on the situation, you may need to install an independent permeable membrane to serve as a vapor barrier.
Can you store ROCKWOOL outside?
