5 cm 70 kg/m³ Rock Wool
Product Description
5 cm 70 kg/m³ rock wool is a high-quality mineral wool insulation board manufactured from natural basalt rock that is melted at extremely high temperatures and spun into fine fibers. Its increased fiber density enhances both thermal insulation and acoustic performance, making it an excellent solution for projects that demand greater energy efficiency and indoor comfort.
With a 5 cm thickness and 70 kg/m³ density, this insulation board provides improved mechanical stability while remaining lightweight and easy to install. Its A1 non-combustible fire classification ensures outstanding passive fire protection for residential, commercial, and institutional buildings.

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 than 60 kg/m³ rock wool, making it a better choice for applications requiring higher durability and sound control.
Where is 5 cm 70 kg/m³ rock wool commonly used?
It is commonly used in exterior wall insulation systems, interior walls, suspended ceilings, office buildings, commercial spaces, and energy-efficient construction projects.
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 excellent passive fire protection.
Does it improve energy efficiency?
Yes. Its low thermal conductivity helps reduce heat transfer, improving year-round indoor comfort while lowering heating and cooling energy consumption.
