The choice between Rockwool (mineral wool) and glass wool insulation depends on various factors, including insulation requirements, budget, environmental considerations, and application-specific needs. Both materials offer excellent thermal and acoustic insulation properties, but they have distinct characteristics that may make one more suitable than the other in certain situations.
Both rock wool and glass wool provide effective thermal insulation, helping to maintain indoor temperatures and reduce heating and cooling costs.
Rock wool generally has superior fire resistance compared to glass wool. Mineral wool is made from natural stone fibers, which are non-combustible and can withstand extremely high temperatures without melting or emitting harmful gases.
Both materials offer excellent acoustic insulation properties, reducing noise transmission between rooms and floors. However, Rockwool is often preferred in applications where soundproofing is a primary concern due to its denser composition.
Rock wool has better moisture resistance compared to glass wool. Mineral wool can repel water and moisture, making it suitable for areas prone to high humidity or moisture exposure, such as basements and bathrooms.
Both Rockwool and glass wool are considered environmentally friendly insulation options. They are typically made from recycled materials and can be recycled at the end of their lifespan. However, some manufacturing processes may involve high energy consumption and emissions, so it's essential to consider the environmental footprint of the specific product and manufacturer.
In general, glass wool insulation tends to be more cost-effective compared to Rockwool. Glass wool products are often cheaper to manufacture and purchase, making them a popular choice for budget-conscious projects.
Ultimately, the choice between Rockwool and glass wool insulation depends on the specific requirements of the project, including thermal performance, fire resistance, acoustic properties, moisture resistance, environmental considerations, and budget constraints. It's essential to evaluate the pros and cons of each material and select the one that best meets the needs of the application while considering long-term performance and sustainability goals. Consulting with insulation professionals and considering product specifications can help make an informed decision.

Glass wool insulation products and rock wool insulation products have now become the main insulation materials. Household needs, industrial needs, and major businesses also use various insulation materials. It is important to ensure you have the best insulation for the job. Both have their pros and cons. We&#;ve outlined some of the important factors to consider when deciding if fibreglass or mineral wool will be best for your project.

There has been much debate over the merits of rockwool compared to glasswool insulation. In the developing part of the world, there is also a lot of mis-information around the two materials. The simple answer is that the best material is dependent on the application and specific performance requirements.
Glass Wool
R value measures the resistance of heat transfer from one side of an object to another, the higher the R value, the greater the resistance, and better insulation power. When comparing the two, glass wool has a slightly lower R-value of around 2.2-2.7 compared with 3.0-3.3 of mineral wool, which means it is slightly less effective at preventing heat loss through conduction.
Compressive strength is required where a construction may be put under high weight loading. Not only can rock be made up to 200kg in density (compared to glass at 110kg) each m3, it can also give a more cost effective performance where compressive strength is the primary requirement. The typical application where compressive strength is required is flat roof.
In terms of sound insulation, mineral wool is often the preferred choice for noisy areas. This is because it is much more dense than glass wool, so much less sound travels through the insulation.
Glass Wool
Although both rockwool and glasswool are non-combustible, rockwool has far better fire resistant qualities, so much so that it can be used as a fire stop. The simple fact is that a high density mineral wool product (120kg m3) is required to stop fire. At these densities, rockwool is the most cost effective solution and provides excellent fire protection. However, like glass mineral wool, low density rockwool insulation will not burn, but will also not stop flames from penetrating between the fibres. In short, for fire protection of construction, high density Rockwool is the ideal solution.
Maximum service temperature is a measure indicating the maximum continous temperature at which an insulation material can operate without any loss in thermal insulation performance. A common misunderstanding is that this is the maximum temperature before the product burns. This is not the case, all mineral wool is non-combustible. However, rockwool is able to tolerate higher temperatures without any loss to its insulation properties than glasswool. Typically, glass mineral wool can operate up to 400°C (typically 230°C without modification) whereas rock can operate up to 700°C. For this reason, in high temperature process plants, rockwool is the most commonly found insulation type.
It is a common misconception that glass or rock mineral wool fibres are damaged by water. However, water can occupy the cells between the fibres, replacing the insulating pockets of air and thus stopping the material from performing its thermal insulating requirements. The lighter the density, the easier it is for the water to penetrate. Importantly, the water resistance of mineral wool (Glass and Rock) can be engineered to meet the conditions of their application and silicon is added as a water repellent stopping water from penetrating the air pockets whilst in situ in the application.
