10 cm 70 kg/m³ Rock Wool
Product Description
10 cm 70 kg/m³ rock wool is a high-performance mineral fiber insulation board designed to provide an excellent balance of thermal efficiency, acoustic insulation, and mechanical durability. With its 10 cm thickness and 70 kg/m³ density, it offers reliable long-term performance for standard residential, commercial, and light industrial construction projects.
Its fibrous structure effectively reduces heat transfer while absorbing airborne sound, creating more comfortable, energy-efficient, and safer indoor environments. The material is also classified as A1 non-combustible, providing outstanding passive fire protection.

Roof Insulation
Reduces heat loss in winter and limits heat gain during summer, improving overall building energy efficiency.
Interior Acoustic Applications
An excellent choice for partition walls, suspended ceilings, meeting rooms, classrooms, and other spaces requiring effective sound absorption.
Advantages
✔ Improved mechanical strength with excellent dimensional stability
✔ Enhanced acoustic performance for greater indoor comfort
✔ Excellent thermal insulation that helps reduce heating and cooling costs
✔ A1-rated non-combustible material for superior fire safety
✔ Long-lasting durability with resistance to moisture, mold, and pests
Installation Tips
-
Install the insulation boards in a staggered pattern to improve structural stability and reduce thermal bridging.
-
Ensure the boards fit tightly together without gaps.
-
For exterior applications, always protect the insulation with render, cladding, or another approved weather-resistant finishing system.
-
Use mechanical fasteners or insulation adhesives appropriate for the building system and local installation requirements.
Frequently Asked Questions (FAQ)
What is the difference between 70 kg/m³ and 60 kg/m³ rock wool?
70 kg/m³ rock wool provides greater mechanical strength, improved dimensional stability, and better acoustic insulation compared to 60 kg/m³ rock wool, making it more suitable for applications requiring enhanced durability.
Which projects is it best suited for?
It is ideal for standard residential buildings, commercial properties, exterior wall insulation systems, roof insulation, and interior acoustic applications.
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 reliable passive fire protection.
Does it improve energy efficiency?
Yes. The combination of 10 cm thickness and low thermal conductivity significantly reduces heat transfer, helping lower energy consumption while improving year-round indoor comfort.
