What is Mineral Wool Roof Insulation?

A mineral wool roof insulation board is a high-density, rigid industrial thermal and acoustic insulation material manufactured from natural basalt rock.

Specifically designed with high compressive strength and excellent dimensional stability, it is widely used for flat roofs, commercial building decks, and waterproof roofing systems to minimize heat loss, support foot traffic, and improve overall energy efficiency.

Key Advantages for Roof Applications

High Compressive Strength

Superior load-bearing capacity ensures the boards stay firmly stable under heavy foot traffic and roofing equipment.

Exceptional Energy Saving

Low thermal conductivity drastically reduces thermal bridging and overall building energy consumption.

Superior Fire Safety

Certified Class A1 fireproof material prevents external flame propagation across commercial roof decks.

Weather & Moisture Resistance

High hydrophobic rate and vapor permeability prevent moisture accumulation and preserve membrane integrity.

Frequently Asked Questions (FAQ)

What is the recommended density for mineral wool roof insulation?

China IKING mineral wool roof insulation boards typically range from 100 kg/m³ to 180 kg/m³ to deliver the necessary compressive strength and structural support for flat roofing systems.

Why is high compressive strength important for roof insulation?

High compressive strength provides high mechanical stability, protecting the insulation from sagging or crushing under foot traffic, installation tools, and subsequent waterproofing membrane loads.

Are your mineral wool roof products certified for international export?

Yes. All IKING mineral wool insulation materials are produced under ISO 9001 standards and comply with international LEED, ASTM compliance requirements.
