What is Mineral Sheet? Properties and Applications

In insulation technologies, the search for performance, safety, and long-lasting solutions is gaining more and more importance every day.  Mineral boards , which are among the leading materials that meet these needs, are versatile insulation products that provide heat, sound, and fire insulation simultaneously. Mineral boards, which are particularly preferred in professional construction projects, stand out with their environmentally friendly structure and high durability.

What is a mineral plate?

Mineral board is a stone wool-based insulation material produced by melting natural minerals such as basalt and dolomite at high temperatures and transforming them into fibers. It is usually presented in the form of rectangular plates  . Thanks to its low thermal conductivity coefficient, it provides high thermal insulation, while its A1 class non-combustible structure offers fire safety. It also supports acoustic performance thanks to its sound insulation properties.

Technical Specifications

  • Material:  Stone wool (mineral wool)

  • Thermal conductivity coefficient (λ):  ~0.033 – 0.041 W/mK

  • Fire reaction class:  A1 (non-combustible)

  • Density:  40 – 150 kg/m³ (varies depending on application type)

  • Dimensions:  Typically 50 cm x 100 cm / 60 cm x 120 cm

  • Thickness:  30 mm – 150 mm

  • Sound insulation:  High sound absorption capacity.

  • Water repellency:  Hydrophobic (water-repellent) production is possible.

Applications of Mineral Plates

📍  Exterior thermal insulation systems (cladding)
📍  Partition walls
📍  Roof insulation (terraces and pitched roofs)
📍  Suspended ceilings and drywall partitions
📍  Fire-resistant insulation solutions for industrial buildings
📍  Sound insulation for interior spaces (studios, offices, schools)

Advantages of Mineral Plates

✅  Provides High Thermal Insulation.
Thanks to its low thermal conductivity coefficient, it reduces energy losses and increases energy efficiency.

✅  Class A1 Fire Resistance Feature
: Provides fire safety to the building. Resistant to high temperatures.

✅  Provides sound insulation and
acoustic comfort. Absorbs airborne sounds.

✅  Dimensional Stability:
It maintains its shape unaffected by temperature changes; it does not shrink or expand.

✅  Breathability:
It has high vapor permeability, preventing moisture accumulation within the structure.

✅  Environmentally Friendly and Recyclable:
Produced with natural raw materials, it does not harm nature.

What should be considered when choosing a mineral slab?

  • The density  and  thickness should be selected according to the intended use   .

  • A fire resistance  certificate (EN 13501-1 / A1 class) is required.

  • The product’s  CE, TSE, and ISO certifications  should be checked.

  • Water repellency is an important feature in exterior facade applications   .

❓ Frequently Asked Questions (FAQ)

What is a mineral slab?

Mineral board is an insulation product made by compressing fibers obtained from natural stones, providing heat, sound, and fire insulation.

Where is it used?

External wall insulation is used in roofs, partition walls, industrial buildings, and areas requiring sound insulation.

Is it fire resistant?

Yes. Mineral panels are A1 class non-combustible material and exhibit superior fire resistance.

Is it waterproof?

When manufactured with hydrophobic (water-repellent) properties, it repels water and is unaffected by moisture.
