Why Use Mineral Wool Insulation?

Mineral wool insulation has become a popular insulation material due to its many useful properties including the fact that it is easy to handle and that it is more affordable than some other types of insulation. But before we go any further let’s answer a basic question: what is mineral wool?

In case you are unfamiliar with it, mineral wool is fashioned from a type of spun yarn which itself is made from stone (typically molten volcanic rocks) or glass fibres. These threads of yarn are woven in a very specific way to create a wooly structure. This wooly material is then compressed into boards or batts to create an easy to work with form of insulation.

At Licata we employ mineral wool as part of our EWI system. But that is far from the only use for this particular material. Various forms of mineral wool is:

Used as thermal and acoustic insulation in walls and floors.
Used to insulate attics to produce a more effective insulation profile for a home.
Used to insulate both flat and pitched roofs.
Used to insulate various types of industrial machinery such as air conditioners.
Blown into wall cavities in timber frame strcutures to act as insulation (loose mineral wool only).

The Advantages of Rockwool Insulation

Mineral wool system provides several impressive benefits that make it a natural fit for our EWI cladding system. These include:

Outstanding thermal insulation

Mineral wool’s open fiber structure enables it to trap a large amount of air within, making it an ideal choice as an insulation product. Mineral wool’s lambda value (its thermal conductivity) is 0.03 W/mK to 0.04 W/mK, meaning it is not susceptible to thermal degradation. As a result it will maintain a stable level of thermal performance for as long as it is in place.

Mineral wood is fireproof

Because it is fashioned from glass or stone mineral wool insulation displays impressive fire resistance and does not abide excess heat. As such it is ideal for environments where there is a high priority on fire safety, such as residential and commercial structures. While we employ it as part of our EWI cladding system it is also employed to create a range of other fireproof products which need to withstand temperatures that would render other insulation materials useless, including fireproof doors, fireproof partition walls and ceilings and various types of fireproof clothing. Mineral wool is classified as a Euro Class A material and has the best fire safety score of all insulation materials.

Mineral wool is stable

Many types of insulation compress or otherwise change shape over time, thereby compromising their effectiveness and eventually necessitating replacement. Not rockwool external wall insulation. Throughout its lifespan mineral wool neither shrinks nor expands, which contributes to the overall long-term effectiveness of our EWI cladding system.

Excellent acoustic performance

Mineral wool does an outstanding job blocking noise pollution due to its structure. This helps the Licata EWI system contribute to a more energy-efficient structure, and one that is quieter as well. This outstanding ability to block sound waves also makes mineral wool an ideal choice for creating acoustic tiles for ceilings, floors and walls that need to absorb sound.

Mineral wool does not absorb moisture

Because of its composition and structure mineral wool does not absorb moisture. As such it will not end up harbouring mould no matter how much moisture it is exposed to. Mineral wool is also completely recyclable, just adding to its impressive list of eco-friendly credentials.

Frequently Asked Questions (FAQs)

1. What is mineral wool insulation used for?

Mineral wool insulation is widely used to improve thermal efficiency and reduce heat transfer in buildings. At Licata, we incorporate this material into our EWI systems to insulate cavity walls, floors and partition walls, helping clients lower energy usage and enhance internal comfort.

It also provides excellent thermal and acoustic insulation, making it ideal for both residential and commercial projects. The stone wool fibres trap static air within the material’s open cell structure, offering a physical barrier that slows radiative processes and helps regulate indoor temperatures.

2. How is glass wool insulation different from mineral wool?

Glass wool insulation is made from recycled glass and sand, while stone mineral wool insulates using volcanic rock as the base. Both are formed into a woolly matrix of fibres, but stone wool tends to offer better fire resistant properties and performs well under high temperature conditions.

At Licata, we focus on mineral wool because of its non combustible nature, low thermal conductivity, and long-lasting thermal performance. Unlike glass wool, mineral wool maintains its structure over time and is less prone to sagging, ensuring stability across walls, ceilings and floors.

3. Is acoustic mineral wool good for sound absorption?

Yes, acoustic mineral wool is highly effective at reducing noise. Its porous structure and carefully controlled mix of raw materials create narrow airways that disrupt sound waves and reduce airborne sound. This helps to form sound barriers within walls, ceilings and partition walls.

At Licata, our mineral wool insulation is used to improve both energy efficiency and sound absorption. The material acts by holding air molecules in place, reducing air movement and dissipating sound energy before it spreads through the structure.

4. Does mineral wool work well for fire resistance?

Absolutely. Mineral wool is classified as a non combustible material and delivers excellent fire resistance. Stone wool can withstand very high temperature without melting, making it ideal for use in fire-rated walls and ceilings where safety is paramount.

Our Licatatherm system uses mineral wool slabs designed to meet strict fire safety standards. With added friction fitting and additional fixings, this insulation supports fire containment strategies while still enhancing thermal performance and acoustic insulation.

5. Can glass wool be used as acoustic insulation?

Glass wool can be used for acoustic insulation, but it is less effective than acoustic mineral wool in some applications. While both reduce noise, mineral wool’s woolly structure and air-trapping properties provide better sound absorption across a wider range of frequencies.

At Licata, we prioritise mineral wool because it offers stronger results in sound control, particularly for cavity walls and partition areas. The material’s narrow airways and low solid material content help manage sound energy and minimise internal noise transmission.

6. How long does mineral wool insulation last in buildings?

Mineral wool insulation is highly durable and does not compress, sag or shrink over time. It maintains a stable level of thermal performance for decades, even in demanding industrial applications. Its structure prevents mould growth and degradation from moisture.

At Licata, we use high-quality mineral wool materials with proven lifespan and performance. Thanks to its friction-fit design and resistance to wear, our insulation ensures lasting results in energy efficiency, sound reduction, and fire protection for a wide range of properties.
