Mineral Wool

Mineral Wool for Sound Insulation – Boards and Rolls for Walls, Partitions, and Ceilings

The “Mineral Wool” category includes high-quality solutions for sound insulation and thermal insulation of walls, plasterboard partitions, and ceilings. Mineral wool is one of the safest and most effective choices when the goal is real noise control, improved acoustics, and long-term reliability.

Suitable for:

• Residential spaces
• Offices and administrative buildings
• Studios and commercial premises
• Industrial spaces

The difference becomes noticeable from the very first acoustic load.

Types of Mineral Wool – Boards or Rolls?

Mineral wool is available in two main formats:

🔹 Mineral Wool Boards

Suitable for walls and plasterboard partition systems.

Advantages:

• Higher density
• Excellent stability between metal profiles
• Better installation control
• Suitable for higher sound insulation requirements

🔹 Mineral Wool Rolls

More commonly used for ceilings and large surfaces.

Advantages:

• Faster installation
• Fewer joints
• Excellent adaptation to the structure
• Suitable for covering uneven surfaces

The choice between boards and rolls depends on the specific construction and acoustic requirements.

How Does Mineral Wool Work for Sound Insulation?

The effectiveness of mineral wool depends on three key factors:

• Density – higher-density wool absorbs low frequencies more effectively
• Elasticity – reduces vibration transmission
• Thickness – typically 50 mm, 75 mm, or 100 mm depending on the requirements

Mineral wool absorbs a wide range of frequencies — from low vibrations passing through concrete slabs to high-frequency sounds such as voices and everyday noise.

Important: cavities and empty spaces act as resonators and reduce effectiveness. Proper filling is critical.

Fire Resistance and Safety

High-quality stone wool and glass wool are non-combustible and resistant to high temperatures.

This makes them a dual-purpose solution:

• Sound insulation
• Fire protection

This is especially important for intermediate partitions, ceilings, and structures containing installations.

Mineral Wool Installation – The Key to Efficiency

Proper installation determines the final result.

Main Principles:

• The wool should be installed tightly without excessive compression.
• There should be no gaps between individual elements.
• In plasterboard systems, the material should lightly “lock” between the profiles.
• Vapor barriers may be required, especially for ceilings under roofs or areas with high humidity.

Good sound insulation is not just about the material, but about the entire system.

Stone Wool or Glass Wool?

Stone Wool

• Higher density
• More rigid
• Suitable for higher acoustic requirements

Glass Wool

• Lighter
• More flexible
• Easier to install
• Suitable for ceilings and large surfaces

Both types provide excellent sound insulation, and the choice depends on the specific project.

Frequently Asked Questions (FAQ)

How thick should mineral wool be?

Typically, 50–75 mm is sufficient for standard walls. For higher performance requirements, 100 mm is recommended. Density is just as important as thickness.

Can complete soundproofing be achieved using only mineral wool?

No. Mineral wool is a key component, but it works best in combination with plasterboard, decoupled profiles, and anti-vibration connections.

How long does mineral wool last?

For decades. It does not develop mold, sag, or lose its properties when properly installed.

Does it also reduce heat loss?

Yes. In addition to sound insulation, mineral wool also provides extra thermal insulation.
