What is Stone Wool?

Stone wool, also called rock wool, is made by melting natural volcanic rocks, such as basalt, at extremely high temperatures and spinning them into fibers. It provides excellent thermal insulation, soundproofing, and fire resistance, making it one of the most popular insulation materials in construction.

---

Thermal Insulation

• Low thermal conductivity minimizes heat loss in buildings.

• Keeps interiors cool in summer and warm in winter, reducing energy costs.

• Environmentally friendly, contributing to sustainable construction.

---

Sound Insulation

• Dense structure effectively reduces noise.

• Ideal for homes, offices, studios, and industrial facilities.

• Enhances interior comfort and complies with building regulations.

---

Fire Resistance

• Stone wool is a non-combustible material (A1 class).

• Retains its shape at high temperatures and prevents fire spread.

• Essential for high-rise buildings, public structures, and industrial facilities.

---

Applications

• Exterior wall insulation (facade systems)

• Roof and floor insulation

• Partition walls for soundproofing

• High-temperature industrial insulation

• Pipe and duct insulation

---

Sustainability

• Made from natural stones, stone wool is eco-friendly.

• Long-lasting, low-maintenance, and recyclable.

• Recognized as a key sustainable building material.

---

Conclusion

Stone wool provides outstanding performance in thermal, acoustic, and fire insulation, making it one of the most widely used insulation materials today. For buildings requiring durable, safe, and environmentally friendly insulation, stone wool is the ideal choice.
