Rock Wool
What is Rock Wool
Rock Wool, also known as mineral wool, is a type of insulation material made from volcanic rock, typically basalt or diabase, that is melted and spun into long fibers. The fibers are treated with a binder to form a mat or board that is used for insulation in buildings, industrial applications, and other settings. Rock wool is known for its high thermal resistance, fire resistance, and sound absorption properties. It is also resistant to moisture, insects, and rodents.
Benefits of Rock Wool
Thermal And Acoustic Insulation
Rock wool is an excellent thermal and acoustic insulator, which makes it an ideal material to use in buildings, homes, and other structures. It helps to maintain a constant indoor temperature by reducing the transfer of heat and sound.
Fire Resistance
Rock wool is a non-combustible material that does not burn or release toxic fumes, making it an ideal fire-resistant insulation material. It can help prevent the spread of fire within a building, providing more time for evacuation.
Moisture Resistance
Rock wool has a low water absorption rate, making it resistant to moisture, mold, and mildew. This makes it ideal for use in areas that are prone to high humidity or water exposure, such as bathrooms and kitchens.
Durability
Rock wool is a durable material that can last for decades without losing its insulating properties. It is resistant to compression, settling, and sagging, which means that it can maintain its shape and effectiveness over time.
Eco-friendly
Rock wool is made from natural minerals and recycled materials, which makes it an eco-friendly insulation solution. It is also recyclable, and can be repurposed at the end of its life cycle.
Easy To Install
Rock wool is easy to install in a variety of applications. It can be cut to size and shape, and can be installed in walls, floors, and ceilings with minimal disturbance to the existing structure.

7 Things to Know About Rockwool Insulation Before Installing It in Your Home
Rockwool Is Made Of Rocks Heated To Become Lava-like Liquid
The process by which Rockwool insulation is made helps to explain the true fire-resistant potential of this product. It's composed primarily of basalt rock and a recycled steel-making byproduct known as slag. These components are superheated, allowing them to liquefy and mix together into a lava-like liquid. In order to melt these substances, the temperatures must exceed 2,900 degrees Fahrenheit.
The mixture is then blown into a large spinning chamber designed to stretch the superheated liquid into fibers. These fibers are then gathered together and compressed into a mat, which can be cut into slabs of Rockwool insulation.
By creating Rockwool through this process, all organic matter is eliminated, greatly increasing the mold- and mildew-resistance of the finished product.
It Contains Between 16 To 75 Percent Recycled Material
The confusion about the amount of recycled material used to make Rockwool insulation can mostly be attributed to the statistics about mineral wool insulation in general. Rockwool is a brand-specific type of mineral wool insulation that is so popular the name became synonymous with the appropriate term, which is mineral wool. The brand-specific Rockwool insulation is typically made of between 16 to 40 percent recycled materials, according to the manufacturer. However, the U.S. Department of Energy has stated mineral wool insulation contains an average of 75 percent of recycled materials.
This estimate is hard to back up because the Department of Energy makes the distinction between standard 'rock wool' insulation and 'slag wool' insulation, but doesn't note the difference in the amount of recycled material for each product.
In general, it can be derived that the amount of recycled material in Rockwool insulation is not precise because it ultimately depends on the specific product. Standard Rockwool insulation may only have between 16 to 40 percent recycled material, while slag Rockwool insulation can be made with up to 75 percent recycled material.
Rockwool Has Excellent Heat Retention
Both fiberglass and Rockwool are effective at keeping a home cool in the summer and warm in the winter, but the specific thermal efficiency of these materials favors Rockwool. While fiberglass insulation is capable of offering an R-value of about 2.2 to 2.7 per inch of insulation, Rockwool has an R-value between 3.0 to 3.3 per inch of insulation.
Fiberglass insulation also tends to lose its thermal efficiency over several years as it begins to degrade. Due to the method of construction and the materials used to make Rockwool insulation, the thermal performance of this insulation remains stable over the lifetime of the building. However, Rockwool tends to cost more per square foot than fiberglass insulation.
The Material Is Fire-resistant Up To 1,400 Degrees Fahrenheit
As noted previously, Rockwool insulation is formed from literal rocks and steel slag that must be heated beyond 2,900 degrees Fahrenheit in order to mix the component materials and create this highly effective insulation. With this in mind, it makes sense that mineral wool products in general can resist fire, flames, and heat up to 1,400 degrees Fahrenheit, while some Rockwool products are capable of resisting temperatures up to 2,150 degrees Fahrenheit without melting, smoking, or catching on.
This impressive heat-resistance is ideal for building homes because the insulation forms a fire-resistant barrier between the interior and exterior of the home, between rooms, and even between floors, slowing the spread of fire. It should be noted that fiberglass insulation is also highly heat-resistant, though it begins to melt at about 1,100 degrees Fahrenheit.
Rockwool Is A Highly Durable Insulation Option.
The durability of this insulation material is difficult to dispute, given that it is capable of retaining its thermal efficiency over several decades with minimal degradation in its R-value. This is primarily due to the materials used to make Rockwool insulation, including rock and steel slag, which are known for having a high level of durability and natural resistance to decay and corrosion.
However, the durability of Rockwool isn't limited to the heat retention quality of the material. The impressive water-resistance, mold-resistance, mildew-resistance, and fire-resistance also contribute to the durability and capability of Rockwool insulation. This is especially true of the material's moisture-resistant qualities, without which the insulation could absorb and retain water from highly humid air, causing the premature breakdown of the material.
Rockwool Insulation Is Great For Soundproofing Rooms.
Some people may not appreciate the heftiness of Rockwool insulation because it does tend to be thicker than fiberglass insulation, but this helps to slow the transmission of heat and it has the added effect of slowing sound waves. As sound waves attempt to move through the material, they are slowed and sometimes completely blocked, creating built-in soundproofing.
While the thickness of the insulation helps to block noise, it is the density of Rockwool insulation that provides the soundproofing. Fiberglass insulation has a density of about 0.5 to 1.0 pounds per cubic foot, allowing it to reduce sound by 4 to 10 decibels. Rockwool insulation has a density of around 1.7 pounds per cubic foot, which is capable of consistently dampening sound by 10 to 15 decibels.
Rockwool Allows Moisture To Escape And Prevents The Growth Of Mold
The construction and composition of Rockwool makes it ideal for rooms that are prone to high levels of humidity, like the bathroom or kitchen. Rockwool insulation's moisture-resistant and vapor-permeable qualities mean that any liquid water will drain away from the insulation instead of soaking into it, while gaseous water vapor will pass through without dampening the material.
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. In fact, Rockwool products are also tested and certified as resistant to fungal growth, reducing the chance that users will open up the wall and find a dangerous biological problem waiting for them.
If you're not sure whether to opt for rockwool or fibreglass (also known as glass wool) insulation, here's a direct comparison of the two types of insulation:
Rockwool is thicker than fibreglass, increasing its thermal performance and acoustic soundproofing
Stone wool insulation doesn't hold onto water, but fibreglass can if it gets wet, which may cause damage and potentially lead to insulation mould
Rockwool tends to be a little more expensive than glass wool insulation
Mineral wool insulation tends to be more durable than fibreglass
Rockwool is typically less itchy and dusty to handle than fibreglass insulation
It's Fire Resistant
The boiling point of a more common fiberglass insulation can average between 1,000–1,300ºF (537.7–704.4ºC).
It's Water Repellent
It is also completely resistant to rot, mildew, mold, and bacterial growth – contributing to a safer indoor environment. Regular Fiberglass will hold water for a long time, slowly collecting at the bottom and causing mildew and rot on the surrounding walls. ROCKWOOL can't stop a pipe from bursting in the wall, but it can help with what comes after.
ROCKWOOL insulation is made from natural stone and recycled material. Its non-directional fiber structure and high density give it better dimensional stability. This “mineral wool” gives great insulation benefits to a house and makes it more difficult for rodents to just chew through (not without some serious discomfort that is).
Installed in exterior walls is a great way to save energy, but there are other applications where it can make a big difference in a home's comfort. Insulating the exposed concrete walls in basements, above cathedral ceilings and in attics are all effective ways to improve a home's energy efficiency.
Unlike normal insulation, is an innovative and high-density insulation that's specifically designed to absorb sound and reduce noise from traveling from one room to another. It traps sound waves and vibrations in the thousands of tiny interconnected spaces created by its unique fiber structure.
Precautions To Take With Rockwool
Because rockwool is an inorganic, manufactured product created from volcanic rock, it's essential to consider proper care and safety measures before you start growing with it. The dust created by the shifting or cutting of rockwool is especially harmful to the human body. Wearing gloves, goggles, and a facemask can prevent the basaltic dust from getting in your eyes and mouth.
It's also important to remember that rockwool isn't bio-degradable like many other grow mediums. If you throw old rockwool away, it won't disintegrate in a landfill for a long time. This doesn't mean it's impossible to dispose of, however. If you've reused your rockwool until the end of its lifespan, you can chop or grind it into smaller pieces and compost them in an outdoor garden. The benefits of rockwool will still apply to the roots of your plants that grow in soil or mulch, aerating the roots and soaking up moisture for them to drink.
Gardening with rockwool for plants, knowing what it is, and what it is made of will enhance your hydroponic gardening experience with one of the best types of growing mediums.
