Many readers have asked questions regarding rock wool insulation and I decided this was an interesting topic to exploring.
There are many interesting and amazing tips and suggetions about health that you may not know. for example health screening Whether you’re interested in health, food sources, or natural history, you’ll find the information you need on About Health.
If you’re unfamiliar with the term rockwool fire barrier insulation also known as mineral/stone wool insulation, it is a fire-resistant insulation product. Additionally, most rock wool insulation items are water and moisture-resistant and have excellent sound-proofing properties and are easy to put in.
Excellent Properties For Fire Resistance
Like you see on this photo the type of insulation that is made from rock wool is extremely fire-resistant. The Brand insulation (shown) has a melting temperature of 2,150 degrees.
This obviously provides it with a significant benefit over insulation products such as fibreglass, foam, and cellulose, which can all be flammable at lower temperatures.
The fire-resistant properties are so effective that this kind of product is commonly used for insulation around fireplaces and chimneys as well as circumstances where the insulation needs to be open.
Naturally, these kinds of applications have to be approved by your local building code official and satisfy the standards of the city’s building codes.
Excellent Water & Moisture Resistant Properties
The insulation made of rockwool fire barrier also has great water and moisture resistance properties. It is for instance, it does not absorb moisture and will not decay, cause mildew, fungi, bacteria, or feed vermin.
When you think of the devastating results of mould damage in modern-day homes, it’s not surprising that more people do not insulate their homes with this type of product!

One of the qualities of this insulation we truly love is the way it is dimensionally solid in terms of dimensional stability. Rock wool insulation products keep their form very well.
In contrast to fibreglass insulation, which is easy to compress, and unlike cellulose which will settle over time, it will keep its shape. This is crucial when a tight fit is all it takes to keep the insulation in the right place.
Earthwool Vs. Rockwool
Selecting the best insulation material that is suitable for the home you live in is crucial to us! We set our sights on the top of the line to provide you with the most accurate details on our various products. You can make your own choice “Earthwool or Rockwool. What do you think?
What Is Earthwool? Insulation?
Earthwool, also known as fibreglass, is made of up to 80 percent recycled glass. Utilising an eco-friendly Binder Resign (ECOSE Technology) earthwool insulation is easy to work with and easy to install.
Acoustic insulation made of earthwool is denser than standard insulation batts, which helps to block out sound and reduces transfer from outside the house.
Earthwool insulation key benefits:
- High thermal performance
- The low itching factor
- 50-year warranty
What Exactly Is Rockwool Insulation?
As the name suggests, Ecotherm floor insulation is made of rock like basalt. It is then melted, and spins at high speeds, creating fibres that make up insulation rolls or batts and no binder resin is utilised.
The two types of insulation, Rockwool and Earthwool insulations, limit heat transfer by encapsulating air inside tiny air pockets made by the insulation fibres. It is essential not to reduce the size of Rockwool insulation, as this could decrease its insulation capabilities.
In addition, Rockwool insulation is known for its outstanding fire rating, as it’s non-flammable, does not transmit heat, and is able to withstand temperatures up to 1000°C.
Rockwool Insulation Key Benefits
- Fire Resistance
- Acoustic ratings
- High thermal performance
- 10 year guarantee
Cost – Earthwool In Comparison To Rockwool
The truth is that in Australia, Rockwool insulation is typically at least three times as expensive as Earthwool. The reason for this is the fact that both are in the United States and since Earthwool is compress much more than Rockwool, this facilitates transportation and lower costs for transport.
Don’t the cost mark of Rockwool insulation you off! This insulation offers outstanding thermal, acoustic, as well as moisture rating for any situation in which requirements for fire ratings must be me.
Acoustic Ratings – Earthwool And Rockwool
Because of its density, Rockwool is a highly effective blocker for the transfer of sound between rooms. It can be in a range of purposes, such as office buildings, residential homes or hospitals, as well as retail stores.
However, earthwool insulation comes with an acoustic component call sound shield that has a higher density than normal thermal batts.
It can be found with R2.0HD, R2.5HD, R2.7HD and R4.0HD. If you are comparing Earthwool and Rockwool in terms of their sound scores, the two are comparable in performance and possess the capacity of absorbing up to 75% of the sound vibrations.
Thermal Rating – Earthwool And Rockwool
The insulation’s thermal rating is know as the R-value. The higher the R-value , the higher the thermal efficiency. Rockwool is believe to have an R-value of between 3 and 4 for each inch, while Earthwool’s insulation is 2.2 to 2.7 in. This indicates that Rockwool has slightly better insulation capacities than Earthwool.
Fire Rating – Earthwool Vs Rockwool
The ecotherm eco versal insulated plasterboard insulation is of stone wool fibres that are not combustible and resist temperatures that exceed 1000 degrees Celsius. It isn’t flammable and can aid in containing the fire within a particular region and impede spreading of the flame.
In the same way, Earthwool insulation is regard as non-combustible, which means that it will not serve as a fuel source to ignite the flame.
The insulation of Earthwool has be test according to AS/NZS 1530.3 codes and is able to provide the fire performance ratings as follows: following: Ignitability: 0 and The Spread of Flame: 0, Heating Evolved: 0. Smoke formation: 0.
What Is The Conclusion?
Overall Rockwool provides high r-values and fire and acoustic ratings; however, it comes with a more expensive price over Earthwool. If a project requires eco versal insulation to meet a particular fire-related requirement, Earthwool will be a cheaper option and it is also non-combustible.
Earthwool insulation comes in a wide range of density ratings and R-values to provide you with the desire results in terms of thermal and acoustic. Please contact Us for additional information about the insulation we offer.
Different insulation materials aren’t identical, and they do not necessarily have the same properties. An understanding of the way walls function is require to know what you can anticipate insulation and building materials to accomplish for you when they’re part of a wall.
If you are able to demonstrate a basic understanding of building science, move forward, if not, take a look at this video about high-performance walls construction and insulation. It’s a good place to get the basics.
Understanding the fundamental physics of how walls function is essential to design sturdy, airtight and well-insulate wall system.
- Loose fill or densely-pack insulation of cellulose
- The roof is being blow by cellulose insulation.
- Recycle Content: 80 % to 100 percent
Form and method Cellulose is up of newsprint that has be shred. It is non-toxic, recycle, and generally local.
It’s ideal for attics because you’re able to blow it up to the dep you desire (with adequate venting) and there aren’t seams that could allow heat loss.
R Value: 3.66 Per Inch
Note the overall conclusion is that this is the best option in terms of performance and environmental impact however, it is not recommend to be use in basements due to its sensitivity to humidity.
Ecotherm roof insulation is a favourite for us because of its long-lasting durability and flexibility. It is completely permeable and safe from moisture; therefore there is less chance of destruction during installation as well and during its life.
There are many interesting and amazing details about animals that you may not have known. For example, ugly goat Whether you’re interested in animals as pets, food sources, or natural history, you’ll find the information you need on About Animals.
It’s hydrophobic (meaning it is unable to take in moisture or water) which means it can wet without creating a huge worry. After drying, it will keep its initial R value.
Due to the constant moisture and humidity issues that cause problems for basements Stone wool is a far better choice for wall insulation in basements than fibreglass.
