The only disadvantages of Rockwool are that it is not biodegradable and can be slightly more expensive than similar insulating materials like fiberglass and cellulose.

Which is better fiberglass or rockwool?

In many ways, mineral wool is a superior insulation product. It has a higher R-value per inch compared to fiberglass, about a 22-37% higher R-value. It contains 70% recycled material, making it a greener product than fiberglass at 20-30% recycled material..

What chemicals are in Rockwool?

Similar to other glass fibers, the chemical composition of rock wool and slag wool are primarily aluminum and silicon oxides. However, these wools possess a higher alkaline earth oxide content (MgO and CaO) and lower alkali metal oxide content (Na2O and K2O) than glass wool.

Do I need vapor barrier with Rockwool?

Because of its greater density and water resistant properties, mineral wool acts as a vapor barrier and, unlike fiberglass, does not need an additional vapor barrier to be effective.

Should I replace fiberglass insulation with Rockwool?

Rockwool insulation typically offers better thermal resistance than fiberglass. Something demonstrated by the fact that Rockwool is usually assigned a higher R-value than fiberglass. R-value is a measure of the heat-resistance capabilities of any given material.

Does rockwool get moldy?

Additionally, Rockwool insulation is inorganic, so it makes a poor medium for mold and mildew to grow as there is nothing for them to use for energy.

What is the difference between rockwool and mineral wool?

What is ROCKWOOL? ROCKWOOL is a company that manufactures stone wool insulation. Also known as mineral wool, stone wool is created by spinning molten rock and minerals with steel slag to create a cotton-candy-like wool product.
