There are various aspects to consider when soundproofing and insulating your home or the office. The two materials do exceptional work of blocking unnecessary sounds.
The materials are energy cost-effective, reduce unnecessary noise from the neighborhood, and also create a comfortable environment for either your family or workers.
The two conventional materials dominate the United States markets, and the demand is quite high. The gradual order is due to many homeowners wanting a relaxed and comfortable environment.
If you need materials that are worth the value of your money and also give value to your projects, then count yourself lucky. The two insulation materials have a lot of benefits and characteristics that will meet your desires.
However, few things make them stand apart from each other. In this article, you’ll get to understand Rock wool vs fiberglass into details so that you can make an informed decision as far as soundproofing is a concern. Let’s find out:

Understanding the Difference between Mineral Rockwool and Fiberglass
Getting to understand the difference between these two sound insulation materials will help you make an informed decision when it comes to insulation. Therefore, take your time to read through the distinction and make an informed decision based on the facts listed below.
Structure of the Materials
The structure outline how the material looks like and how they perform their duty to block unnecessary noise from the environment.
The materials have some slight differences that make them stand apart and also perform different tasks to a certain level. Let’s jump in:
Mineral Rockwool Insulation Material
The fibers of the soundproofing & insulation material are made from stone. The insulator has unique features that make it easy to install.
It can permanently block sound from reaching the comfort of your room efficiently hence fostering sound sleep at night in a noisy neighborhood.
This is another excellent soundproofing material, but it is made from fine strands of woven glasses. It either comes in rolls or blankets to suit the tastes and preferences of users.
The material also comes in different sizes and shapes. The feature gives it the ability to fit on any wall that needs insulation.
Base on the features of how the two materials are made, it is quite clear there is no winner since both have excellent structure.
Therefore, choose the material based on other things apart from the structure of their design. Consider something that is worth the value of your money and project.
When purchasing soundproofing materials, consider if they are made from something that is sustainable. The materials should be environmentally friendly, and they should also meet all the requirements of the U.S. Department of Energy.
The mineral wool insulation is made from eco-friendly components. According to research, Rockwool has about 75% recyclable contents. If you need environmentally friendly materials, then consider mineral wool insulation.
Fiberglass contains about 30 percent of materials that can easily be recycled, making it environmentally friendly. Despite being made from such components, it is still suitable for offering impeccable soundproofing & insulation services for your home or office.
Base on the argument on the components of materials used to make the two insulation materials, there is still no winner as both are eco-friendly.
Good material should be resistant to both water and fire. The two elements have the capability of withstanding heat and also prevent the fire from spreading to another place.
Rock wool Material
Rockwool is highly dense material, and research shows that it has the capability of withstanding up to 1000° C (1800° F) temperatures.
The higher density makes the material more resistant to heat and fire safety when compared to other conventional materials and fiberglass.
This is another excellent material since it has the capability of responding to heat and fire in a significant way. It helps to minimize fire from spreading. According to research, fiberglass has the capability of tolerating about 600° C (1100° F) temperature. This makes it ideal for installation in the house or office.
Heat and fire safety is a distinctive feature that makes these two materials to stand apart. Rockwool material is more resistant over fiberglass. It is an ideal material for offering exceptional fire protection.
Soundproofing & Insulation Performance
These two materials are quite useful when it comes to the reduction of sound pollution and noise. The density and weight play a significant role in this sector. Let’s find out more about each.
Mineral insulation has a high density, and it tends to weigh more than fiberglass material. It is the reason behind its effectiveness and efficiency in noise reduction from the neighborhood.
The insulation material has a high density and good weight that contribute to the reduction of noise into the office or the house. However, the weight and density tend to be lower than that of Rockwool material hence less effective when comparing the two elements.
Rockwool has the capability of reducing sound transmission of about 10 decibels through a wall while the fiberglass material about 4to 10 decibels. Therefore, Rockwool material is a winner under this category since it is quite effective in noise and sound reduction.
The installation of these two insulation materials is almost the same, but one of them tends to be much more comfortable than the other. Let’s find out more here.
Mineral Rockwool Material
The fiber Matts of Rockwool is quite more natural to install since they are highly flexible. It can be installed on the walls with altering with the existing wall finishes. Handling the material during the application does not require ultimate care.
The material is quite flexible. It can be refitted and reused. Cleaning fiberglass is quite more comfortable when compared to Rockwool content. However, when fitting the equipment, you need to be extra careful when handling them.
Rockwool materials are considered to be the best since handling them does not require any form of extra care. It does not release beautiful pieces of stuff like fiberglass that can cause accidents. Many people have more confidence in Rockwool glasses than fiberglass.
Cost of the Materials
The price is another factor that makes these two materials to stand apart, but this does not determine the performance of each. Let’s dig deeper now.
Rockwool Soundproofing Material
This material tends to be quite expensive when compared to other standard materials. The cost has made many people to shy away although they perform excellent tasks as far as insulation is a concern.
Fiberglass Soundproofing Material
Fiberglass materials are quite useful, and they tend to be quite affordable when compared to Rockwool materials. The price of these materials is about half of the Rockwool materials. Take your time and choose the one that serves the purpose well.
Rockwool is quite denser and does a fantastic job when compared to fiberglass. However, the cost tends to be higher than other conventional materials. Fiberglass seems to have a higher demand in the market since it is cost-effective.
Most materials are gauged based on thermal properties. The R-value proves how a product can be resistant to thermal transfer from the wall.
According to research, materials with high R-value make the structure to be resistant to thermal transfer when compared to that with low value. Let’s find out about the two materials here.
Mineral wool Material
The rock wool material has an R-value of about 3.0 to 3.5 per inch. The feature is the reason why they tend to be more massive and dense when compared to fiberglass. They tend to perform a great job as far as insulation is a concern.
The material has R-value of about 2.2 to 2.7 inch. This implies that they are less dense and lighter hence poor insulator when compared to Rockwool content.
The insulation is a factor that varies from one region to another. We have areas that need higher insulation and regions that need lower insulation.
Choose the material according to your area. However, if you need a material that blocks noise and reduces heat, then consider Rockwool materials since they are more substantial as well as dense in structure.
Final Verdict about Rockwool vs. Fiberglass
When the two materials are installed rightly then expect excellent performance as far as insulation and insulation is a concern.
They will keep your house or office warm and cold during the summer. However, fiberglass is considered to be economical when compared to Rockwool material.
Choose the material depending on your region and even consult your local building inspector to help in deciding the case the information above proves a hard nut to crack.
