What is its lifespan? Does it settle?

It lasts 30-50 years. The stable, interwoven fiber structure prevents settling or collapsing over time.

Is it good for soundproofing?

Yes. Its dense fibrous structure offers excellent sound absorption, ideal for studios, machinery rooms, and partitions.

How to identify quality rock wool?

Check for uniform color, no bad odor, firm texture (no shedding), and verify official test reports.

Key construction tips for external walls?

Use a combination of adhesive and anchors for secure fixing. Ensure the system is breathable to prevent moisture buildup.

Rock Wool vs. Glass Wool vs. XPS?

Rock Wool: Best for fire safety (Class A) and soundproofing. XPS: Best for thermal insulation and compression resistance (roofs/floors). Glass Wool: Lightweight and flexible, ideal for internal steel structures and ducts.
