When it comes to insulation, there are a few options available to help you keep your home or business more comfortable and energy-efficient during extreme weather. Among these are batts or blankets, which are placed between studs or posts in a structure, then covered over with some type of hard wall surface, such as drywall or paneling. The materials available for these batts include mineral wool and fiberglass as the most common varieties.

A third option that is very popular is blown-in cellulose insulation. This type of insulation requires a blower that uses air pressure to push the material through a hose into an opening in the wall to place the insulation properly. But which of these there options is best for your situation? Here&#;s a quick look at the benefits and drawbacks of all three types of insulation.
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.. With a density over three times that of fiberglass, mineral wool has superior sound-deadening properties. The stiffer batts don&#;t tend to flop over as easily as fiberglass, making it easier to put in place, and they don&#;t require staples or wire to keep them in place. 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 . 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. Because it&#;s denser, it&#;s also heavier, which can make it more ungainly to handle during ceiling installations. Its dense nature requires the use of a serrated bread knife or wood saw to cut batts down to size, and it&#;s very difficult to find in a loose-fill format.
Here&#;s a quick overview of the R-value you can expect from different depths of mineral wool batting:
- For 2×4&#; R13 to R15
- For 2×6&#; R21 to R23
- For 2×8&#; R30 to R32
- For 2×10&#; R38

Glass wool insulation products and rock wool insulation products have now
become the main insulation materials. Household needs, industrial needs, and
major businesses also use various insulation materials. Can you tell the
difference between glass wool and rock wool? Are their performance and their
uses? In the current market, many people do not know which kind of venue uses
glass wool and which kind of rock wool? Here Huamei Glass Wool and you break
down the use and difference between the two in detail.

1. The difference in production performance:
Glass wool has a lower specific weight than rock wool, low content of slag
balls, low thermal conductivity, long service life, and high fiber toughness.
However, the maximum temperature of rock wool is about 600°C, and glass wool is
only about 260°C.
Glass Wool
Glass wool uses glass as the main raw material, and it is a glass thin-flow
fiber that is subjected to high-speed centrifugation and high-temperature
stretching. Glass wool has a low bulk density, high fiber toughness, low thermal
conductivity, porous, and relatively high-temperature resistance, about 260
degrees; rock wool board is made of basalt as the main raw material, inorganic
fibers made by high temperature melting and high speed centrifugal melting. Due
to the different raw materials, the rock wool board has a relatively high bulk
density, and has the characteristics of acid and alkali resistance, heat
absorption, non-combustibility and high temperature resistance (high temperature
resistance of about 600 degrees).

Glass wool has a high temperature resistance of about 260 degrees. Based on
this, it is mostly used for the insulation of buildings and low-temperature
pipelines. Rock wool board is about 600 degrees of high temperature resistance.
It is mostly used for the insulation of high-temperature thermal pipes or
electrical equipment, as well as fire insulation on external walls.
material.
Glass Wool
2. Differences in product use:
Glass wool is generally used for insulation at temperatures below 200°C. It
is mostly used for insulation of general buildings or low-temperature pipelines.
Rock wool is generally used for insulation at temperatures of 50°C. It is mostly
used for thermal insulation of high-temperature thermal pipes or electrical
equipment.
From the data of materials and other aspects, it is used for thermal
insulation and fire-proofing sites. Rock wool can be used as thermal insulation
and fire protection for sites that require special high-temperature resistance.
From the perspective of cost savings, if the site is not high in heat
resistance, Ordinary thermal insulation can use glass wool, like the roof
insulation of the factory building, glass insulation can be used for wall
insulation; such as large industrial pipes for fire insulation, it is more
reasonable to use rock wool!

3. In addition, Glass Wool and rock wool also have certain differences in
terms of production technology:
Glass wool belongs to a kind of artificial inorganic fiber. It uses quartz
sand, limestone, dolomite, and other natural ore as the main raw materials, and
uses some soda ash, borax and other chemical raw materials to melt into the glass.
In the melted state, they are blown into flocculent fine fibers by means of
external force blowing. The fibers and fibers are three-dimensionally
intertwined and entangled with each other, showing many small gaps. This gap can
be regarded as a pore, so glass wool can be regarded as a porous material, which
has good thermal insulation and sound absorption properties, such as Glass Wool
Batts.
Rock wool products are made of delicate basalt as the main raw material.
After being melted at high temperatures, inorganic fibers are made from
high-speed centrifugal equipment, and then special adhesives and dust-proof oil
are added. The fibers are laid on a swing belt and the fiber arrangement
structure is changed by special equipment. A new lightweight insulation material
made by curing and shaping.
The above is the difference between glass wool and rock wool, I hope to help
everyone.
