In this topic, we discuss the most well-known Raw Materials for Hot and Cold Insulation for Factories, Companies, Corporates, Petroleum/gas/electricity stations in Egypt, UAE and Arab Countries with ArabTronix Team:
Mineral Wool
is also known as mineral
fiber, mineral cotton, mineral fiber, man-made
mineral fiber (MMMF).
There are two types of mineral wool product:
glass wool insulation and stone wool insulation.
How Mineral wool was manufactured?
The process involved blowing a strong stream of
air across a
falling flow of liquid iron slag.

High-temperature
mineral wool
High-temperature mineral wool is a type of
mineral wool created for use as high-temperature insulation and generally
defined as being resistant to temperatures above 1,000 °C.
What’s the Difference: Fiberglass vs. Mineral
Wool Insulation?
· R-Value: The thermal resistance of insulation is measured by
what’s commonly known as the R-value, and the higher the R-value, the better.
Fiberglass has an R-value of approximately 2.2 to 2.7 per inch of thickness.
Mineral wool has a slightly higher R-value, ranging between 3.0 and 3.3 per
inch.
· Size: Fiberglass insulation is available in a wider range of
sizes and types than mineral wool. Mineral wool insulation is typically only
available in unfaced batts.
· Sustainability: Mineral wool is composed of 70 percent or more recycled
content. Fiberglass insulation typically contains 20 to 30 percent recycled
content.
· Cost: Fiberglass insulation costs 25 to 50 percent less than
mineral wool.
·
Density: Mineral wool insulation has superior sound-deadening
properties. It has a density of 1.7 pounds per cubic foot, as compared to 0.5
to 1.0 for fiberglass. Because of its density, mineral wool is hard to
compress. Fiberglass, on the other hand, will lose some of its insulating value
if it’s compressed too tightly.
· Weight: Fiberglass is lightweight and easy to carry, but the
batts are rather limp and can be challenging to set into place. Mineral wool is
heavier than fiberglass, but the batts are also stiffer, so they don’t bend or
flop over as easily.
· Water Resistance: Mineral wool insulation is hydrophobic, meaning it’s
highly resistant to moisture and water. Since it doesn’t absorb moisture,
mineral wool doesn’t promote rot, corrosion, fungi, mold, mildew or bacterial
growth. If fiberglass insulation gets wet, it becomes soggy, and its insulating
value drops significantly.
· Loose-Fill: Loose-fill fiberglass insulation provides a quick, easy
and economical way to insulate attic floors and wall cavities. Loose-fill
mineral wool does exist, but it’s difficult to find.
· Installation: Mineral wool comes in dense, firm batts that are
friction-fit into place; no stapling required. Fiberglass batts must be secured
with staples or wire. To cut fiberglass insulation, compress it flat with a
board or metal straightedge, then slice it with a utility knife. Use a serrated
bread knife or woodcutting handsaw to cut mineral wool insulation. It’s
recommended that you wear a dust mask when cutting and handling any type of
insulation, including fiberglass and mineral wool.
