Product Description

Glass Wool Blanket

Glass wool blanket is quartz sand, limestone, dolomite and other natural ores as the main raw material, add soda ash, borax and other chemical auxiliaries, by more than 1500 ℃ high temperature melting, through the high-speed centrifugal or spray blowing process made of fibers, and then by the application of binder, curing molding and other processes made of flexible thermal insulation and sound insulation materials. Because of its fluffy texture, soft as a blanket, can be bent and folded at will, widely used in construction, industry and other fields.

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.
