5 cm 60 kg/m³ Rock Wool
Product Description
5 cm 60 kg/m³ rock wool is a lightweight mineral wool insulation board manufactured by melting natural basalt rock at extremely high temperatures and spinning it into fine fibers. The air pockets formed within its fibrous structure help reduce heat transfer while effectively absorbing sound waves, providing both thermal insulation and improved acoustic comfort.
With a 5 cm thickness and 60 kg/m³ density, this insulation board offers an excellent balance between cost, performance, and ease of installation. Its A1 non-combustible fire classification also provides reliable passive fire protection, making it suitable for a wide range of residential and commercial building applications.

Frequently Asked Questions (FAQ)
Which projects are best suited for 60 kg/m³ rock wool?
It is an ideal solution for standard residential and commercial buildings, including exterior wall insulation, interior partition walls, suspended ceilings, roof insulation, and prefabricated construction.
Is a 5 cm thickness sufficient?
Yes. 5 cm rock wool is suitable for supplementary insulation, interior applications, partition walls, and projects where moderate thermal and acoustic performance is required. Higher thicknesses may be recommended for projects with stricter energy efficiency requirements.
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 dependable passive fire protection.
Does it provide sound insulation?
Yes. Its fibrous mineral structure effectively absorbs airborne sound, offering 20–35 dB of sound insulation depending on the building system and installation method.
