10 cm 120 kg/m³ Rock Wool
Product Description
10 cm 120 kg/m³ rock wool is a high-performance mineral wool insulation board manufactured from natural basalt rock that is melted at extremely high temperatures and spun into fine fibers. Its 120 kg/m³ density provides enhanced mechanical strength and dimensional stability, while the 10 cm thickness minimizes heat transfer for outstanding energy efficiency.
Designed for demanding construction applications, this insulation board delivers excellent thermal performance, sound absorption, and passive fire protection. Its A1 non-combustible fire classification makes it an ideal choice for projects where safety, durability, and long-term performance are essential.

Frequently Asked Questions (FAQ)
Where can 10 cm 120 kg/m³ rock wool be used?
It is widely used in exterior wall insulation systems, roof and terrace insulation, interior partition walls, industrial buildings, and passive fire protection applications.
What is the difference between 120 kg/m³ and 150 kg/m³ rock wool?
120 kg/m³ rock wool is lighter and more cost-effective while still providing excellent mechanical strength for most construction projects. 150 kg/m³ rock wool offers even greater compressive strength and is better suited for applications requiring maximum durability.
Is it fire resistant?
Yes. It is classified as A1 non-combustible and maintains its structural integrity at temperatures of up to 1,000°C, providing outstanding passive fire protection.
Is it durable?
Yes. When correctly installed and properly protected, 10 cm 120 kg/m³ rock wool can provide reliable insulation performance for 20 years or more, making it a durable and cost-effective insulation solution.
