Whereas rockwool fibers are spun from liquid rock,
fiberglass is spun from liquid glass and glued together with a resin
. It is one of the most popular insulation materials and is cost-effective with an R-value comparable to rockwool.
Is ROCKWOOL good insulation?
Rockwool is comparable with EPS in terms of
its insulating ability
, but there are a few reasons why architects often specify it when they are designing builds. Its high thermal efficiency reduces energy bills for heating and cooling in residential buildings due to the outstanding thermal resistance of the wool.
What type of insulation is Rockwool?
ROCKWOOL insulation is
a stone-based mineral fiber insulation comprised of Basalt rock and Recycled Slag
. The recycled content in mineral wool is derived from the steel slag. ROCKWOOL products contain between 16% or 40% pre-consumer recycled material dependent on the ROCKWOOL manufacturing facility location.
Is ROCKWOOL insulation mineral wool?
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.
Is ROCKWOOL itchy like fiberglass?
Like fiberglass, mineral
wool contact can make you itch or even cause a mild rash
. Some installers say it’s a little worse than fiberglass; some say a little better.
Is Rockwool really better than fiberglass?
Mineral Wool Insulation
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..
Is Rockwool bad for your lungs?
Animal studies have reported an increase in lung tumors in animals exposed to ceramic fibers by inhalation, while no increase in tumors was reported from exposure to glasswool, rockwool, or slagwool. The EPA has classified
refractory ceramic fibers as probable human carcinogens
.
Does Rockwool need a vapor barrier?
And by the way, if you’re remodeling a shower and use Rockwool with KERDI-BOARD or Wedi’s shower system
there’s no need for a vapor barrier
. This is primarily due to the KERDI-BOARD or wedi.
Is Rockwool insulation expensive?
Cost.
Rock wool generally costs more than fiberglass insulation
. Fiberglass insulation rated at R-15 to fit a standard 4-inch wall costs around $0.50 per square inch as of 2013, according to Fine Homebuilding. Rock wool rated at R-15 and designed to fit a 4-inch wall costs $0.62 per square foot as of 2013.
Does Rockwool need a vapor barrier in attic?
My research indicates Rockwool insulation seems to have some useful properties, like the ability to dry out if exposed to moisture. But this same research has come up empty regarding whether providing natural ventilation space behind unfaced Rockwool allows this project to move forward
without a vapor barrier
.
What is wrong with Rockwool insulation?
Not only is
rockwool unfriendly to the environment
– it’s also potentially harmful to your health. New blocks can contain a lot of dust and loose fibers that can get in your eyes, mouth, skin and lungs. … If you’re using rockwool, you should be using a mask, goggles and gloves when you work with it to protect yourself.

Both ‘Rockwool’ and ‘mineral fibre’ are terms that are often used interchangeably, but essentially, they
share the same material make-up – stone wool
– where melted natural rock is spun into long fibre strands, captured and condensed into a high-density mat.
Does Rockwool insulation make you itchy?
Coarse fibers and dust from mineral wool products
can cause emporary and reversible irritation
(itching, redness) of the skin and eyes.
Which is better Rockwool or Earthwool?
What’s the conclusion? Overall
Rockwool
offers high r-values, acoustic and fire ratings, but for a higher price tag than Earthwool. So, unless a project specifies Rockwool to meet a certain fire requirement, Earthwool will be a far more cost effective solution and in still non-combustible.
What is better Rockwool or Celotex?
90mm Celotex or equivalent
will give the best insulation, it’s insulation factor is about twice that of Rockwool. But it needs cutting which takes time and is messy. Rockwool might be easier to install, although you have to keep it in place somehow and if installed vertically ain’t so simple. Its also cheaper.
