Product Description

Product Description

Rock wool

Rock wool is mainly made from natural ores such as basalt and dolomite as the core raw materials, together with appropriate amounts of coke, limestone and other auxiliary materials. Under the extreme high temperature of 1450℃ or even higher, these raw materials are completely melted, and then with the help of international advanced four-axis centrifuges, they are stretched into fine fibers under the action of high-speed centrifugal force. At the same time, a specific amount of binder, dust oil, water-repellent agent is sprayed into the fibers, which are collected by the cotton collector, and then combined with the three-dimensional method of laying the cotton by the pendulum method, and finally cured and cut into various specifications and uses of rock wool products.

FAQ

1. Which insulation material is best for my home (exterior walls/roof/interior walls)?

Exterior walls: Fireproof Class A rock wool boards or foam cement boards (durable). Roof: XPS extruded boards (waterproof and pressure-resistant) or polyurethane spray (seamless insulation). Interior walls: Lightweight EPS boards or fiberglass wool (space-saving).

2.How are fire resistance ratings classified?

Class A: Non-combustible (e.g., rock wool, foam cement).

Class B1: Flame-retardant (e.g., fire-resistant EPS/PU).

For homes, at least Class B1 is recommended; public buildings require Class A.

3. Are your products eco-friendly?

Do you have test reports? Available certifications: Fire resistance test reports (GB 8624). Eco-labels (e.g., green building materials, formaldehyde emission tests).

4. What is the price per square meter?

Example price ranges: EPS boards: ¥20–40/m XPS boards: ¥40–80/m Rock wool boards: ¥60–120/m (Varies by thickness, density, and brand.)

5. How do I calculate how much material I need?

Formula: Area (m²) × Thickness (cm) ÷ Package volume. Example: For 100m² walls with 5cm EPS boards: 100 × 0.05 = 5m² (confirm package specs).

6. What should I know for DIY installation?

Key steps: Clean the base surface (no dust or grease). Ensure tight seams between boards. Use specialized adhesives and anchors. 

7. How long does the insulation last?

Typically 20–30 years, but note: Organic materials (e.g., EPS) degrade under UV exposure. Inorganic materials (e.g., rock wool) must stay dry. 

8. What if the material gets damaged or detaches?

Warranty coverage (usually 1–5 years) for repairs. Small repairs can use structural adhesive. 

9. Does winter installation affect performance?

In low temperatures (<5°C): Use winter-grade adhesives. Avoid rain/snow during installation.
