In terms of thermal insulation materials, rock wool and glass wool are the two most commonly used materials, which can make your home or business more comfortable and energy efficient. Rock wool and glass wool are inorganic fiber materials, both appearance and performance are relatively similar, below, Xiaobian to explain the advantages and disadvantages of rock wool and glass wool, so that you can better choose the right material.

1. Rock wool

Rock wool is mainly made of basalt and slag materials. In many ways, mineral wool is a quality insulation product. Compared to glass wool, it has a higher R value, about 22-37% higher. It contains 70% recycled material, making it a more environmentally friendly product than glass wool, which contains 20-30% recycled material. The density of rockwool is more than three times that of glass fiber, which has excellent sound insulation properties. Harder cotton batting is not as fluffy as glass wool, so it is easier to place in place and does not require staples or wire to hold it in place. Rockwool is hydrophobic, so it does not absorb water, and it does not breed mold, bacteria, etc. In addition, the fire resistance of rock wool is very high, which can play the role of fire prevention.

However, like many building materials, rockwool has its drawbacks. It tends to be more expensive than glass wool, typically costing 25-50% more. In addition, because rockwool is denser, it is also heavier, which makes it more clumsy to handle during ceiling installation. Its dense nature requires the use of a serrated bread knife or a wood saw to cut the cotton tire to size, and it is difficult to find a loosely filled form.

2. Glass wool

Glass wool is made from quartz sand (sand) or recycled glass. The use of glass wool is more common, in part because of its affordable price. Overall, it has a good R-value, even if it's not the best. Another reason for the popularity of glass wool is that it is available in a variety of sizes to add veneers. Glass wool is a green material that contains 20-30% recycled ingredients. It is lightweight and easy to install in a variety of environments, usually using only a flat-headed staple gun. Loose fill options are extensive, allowing you to fill in strange wall holes or add insulation to your attic.

Glass wool also has its drawbacks. Glass wool can be compressed, causing it to lose its R-value. When it gets wet, it absorbs water, causing it to lose its R-value. Although it is a non-combustible material, it does not provide the same fire rating as rockwool. Its R value is not as good as rockwool, and the overall density is lower, so it does not dampen the sound as much as mineral wool.

Both rock wool and glass wool have good thermal insulation properties. Rockwool has better fire resistance and stronger sound insulation, but it is heavier. The price of glass wool is more affordable and the operation is simple, but some properties are not as good as rock wool.

Rockwool insulation is a durable form of insulation that is 75 percent recyclable. Like fiberglass and cotton insulation, rockwool is durable and resistant to high temperatures. It is also water and soundproof. It does not degrade and doesn&#;t require staples to attach it to a wall or ceiling. Its pros and cons are discussed below. Read on to learn more about the benefits of rockwool insulation for your home.

Stone wool insulation is made from molten rock

The production of stone wool is an advanced process that mimics the processes found inside a volcano. The process begins with the spin-off of raw materials like rock, steel slag, or glass. This mixture of molten rock and recycled stone wool is called a &#;charge&#;. It is then melted at temperatures of over degC in a cupola furnace. The molten rock is then spun into strands of fiber by spinning the molten rock. The fibers are then bound together with starch. This method has become a popular alternative to fiberglass insulation because of its ability to protect buildings from heat.

In addition to its thermal and sound insulation properties, stone wool is fire-safe, making it ideal for use in industry. It is also a natural insulator and is a safe alternative to glass wool. Because it is lightweight, stone wool insulation is particularly suited to industrial settings, where temperature levels can reach up to several thousand degrees. But it is important to note that stone wool insulation differs from mineral wool, and that the benefits may vary. The difference between the two types of stone wool will depend on the project and application.

Since stone wool insulation is made from molten rock, it is highly resistant to heat, cold, and moisture. It can be used for structural and pipe insulation, soundproofing, and even hydroponics. But it is important to keep stone wool dry during installation to avoid the formation of mold, mildew, and fungus. And because it can handle temperatures of up to degC, stone wool insulation is fireproof and resistant to extreme temperature.

The process to create stone wool is similar to that of making candy. The rock is melted at a temperature of over degrees Celsius, and air is blown through it. The result is a thread that is approximately two to six microns in diameter. The stone wool fibers are then combined to form a material similar to wool. The natural stone fibers are made up of 98% inorganic and the organic content is usually a thermosetting resin binder or adhesive.

It is non-combustible

The ROCKWOOL GROUP is the world&#;s largest supplier of stone wool insulation solutions. The company was founded in and currently has a worldwide network of 27 manufacturing facilities. The company says its products can save more than 100 times the energy they need to manufacture. Additionally, the company says that using Rockwool in building construction reduces air pollution and CO2 emissions, which helps address environmental problems.

Rockwool insulation is environmentally friendly and non-combustible. It does not deteriorate or degrade over time, which is a huge benefit when comparing it to other forms of insulation. In fact, Rockwool&#;s R-value remains constant for decades. This means that even if it is soaked in water, it will return to its original shape and not degrade in R-value. Because the material is composed of inorganic materials, it doesn&#;t support the growth of mold and mildew.

Unlike foam or cellulose insulation, Rockwool is non-combustible. It can withstand temperatures of up to degC without melting. It is also highly resistant to fire. Fire-resistant, Rockwool stone wool is non-combustible. The stone wool insulation doesn&#;t sag and doesn&#;t absorb moisture. In addition to its high fire resistance, Rockwool also reduces noise transmission.

In a recent press conference, Rockwool executives sought to clarify the meaning of the term &#;fire safe&#; in the UK market. To this end, Rockwool held a series of road shows across Europe. These road shows were attended by dozens of companies, allowing Rockwool to gain greater market share. Although they were a major success, Rockwool executives remained concerned that the term &#;fire safe&#; was being misused.

Its durability is the reason that so many people choose Rockwool for their homes. They can be used to upgrade or refurbish a home. It can be purchased as slabs, rolls, and even in large pieces. You can find rockwool thermal insulation for timber framed constructions, such as cladding or roofing. Rockwool has a fire rating higher than glasswool products and has been tested in temperatures of over °C.

It is non-corrosive

Rockwool insulation is a durable material that can maintain its thermal efficiency and R-value for decades. It is made of basalt rock, recycled steel slag, or steel slag that has been superheated to over 2,900 degrees Fahrenheit. After it has been superheated, the fibers are collected into a mat, which is then sliced into slabs for installation.

The stone fibers in mineral wool contain small air pockets to prevent moisture buildup. The mineral wool is produced by melting basalt rock at 1,600 degrees Celsius, which removes all organic materials from the mineral. The lack of organic matter prevents the growth of mold, mildew, and fungus. The product has an anti-microbial agent and is resistant to heat, which is why it is recommended for use in homes and buildings.

Another benefit of Rockwool insulation is its excellent resistance to moisture. It is vapor permeable, which means that water that contacts its surface simply drains from the material. Traditional insulation materials are quickly weakened by moisture and lose their R-value. In addition to its exceptional thermal insulation properties, Rockwool is fire-resistant, allowing for the escape of smoke and flame without damaging the building. Lastly, the material has excellent acoustic properties. It can decrease exterior noise by significantly reducing the frequency and intensity of sounds.

The material is resistant to heat, which makes it a good choice for walls and floors. The mineral wool also acts as a fire-resistant barrier, slowing the spread of a fire. In comparison, fiberglass insulation melts at about 1,100 degrees Fahrenheit, which makes it a poor choice for fireproofing. And since it is non-combustible, rockwool does not promote corrosion.

Another benefit of Rockwool insulation is that it resists corrosion due to the presence of calcium silicate, which is an alkaline mineral. Calcium silicate has excellent corrosion-resistance and can even prevent corrosion in a wide range of applications. This property is crucial for building materials, as water can cause severe damage to metal. A corrosion inhibitor will prevent corrosion from occurring in these environments. And it will prevent corrosion by keeping your building dry and free of water.

It is resistant to rot

If you&#;re looking for an insulating material that is resistant to rotting, consider Rockwool insulation. This material is composed of fine, intertwined fibers that are about three to four micrometers in diameter. Because of its unique structure, it is able to trap air passing through. Rockwool also contains an oil or binder that enhances its heat-retention capacity and R-value. The resulting properties make rockwool the best material to use as insulation. As rockwool is made from the toughest substance on earth, it is naturally resistant to rot, decay, and moisture.

In addition to its high resistance to decay, Rockwool insulation is also environmentally friendly. The materials used in its production process are a recycled by-product from the steel industry. The US Department of Energy released figures to show that certain rockwool insulation contains up to 75 percent post-industrial materials. These facts make Rockwool an excellent option for insulating your home. If you&#;re looking for a durable material that can last for decades, Rockwool might be the best choice.

Another advantage of rock wool insulation is that it&#;s dimensionally stable. That means it retains its shape, unlike cellulose and fiberglass. That is particularly important when installing rock wood in tight spaces like around the roof. This makes it a good option for pitched-roof insulation. Its unique structure also makes it resistant to rot, which is a key consideration when installing new insulation. It&#;s also resistant to moisture and mold, so it will prevent rot in your home.

Another benefit of Rockwool insulation is its fire-resistance. This material is fire-proof, so it&#;s used around fireplaces and chimneys. Of course, you need to meet local building codes for insulation before installing it. As a mineral wool product, it won&#;t absorb water and doesn&#;t harbor mold or mildew, so it&#;s also a good option for preventing fire.

Another great benefit of rock wool insulation is its durability. It can be compressed to more than kilograms per cubic meter. When you install rock wool insulation in your home, you won&#;t need to worry about it falling apart in the middle. You can even cut it with a serrated knife. The density of rock wool insulation means that it won&#;t slump down when wet. Because of this, it&#;s the ideal choice for exterior walls and roofs.
