Key Features & Benefits
Superior Thermal Insulation
- EPS core with low thermal conductivity effectively reduces heat transfer through the roof.
- Significantly lowers indoor temperatures in summer and retains heat in winter.
- Can reduce air conditioning and heating costs by up to 30% compared to uninsulated roofing.
Excellent Weather Resistance
- Multi-layer baking paint on galvanized steel substrate resists UV, rain, and salt spray.
- Suitable for diverse climates: tropical, arid, temperate, and coastal regions.
- Gray finish resists color fading; RAL color options available for custom projects.
Fire Safety
- Flame-retardant EPS core achieves B2/B1 fire rating (EN 13501-1, ASTM E84).
- Meets international building code requirements for commercial and industrial structures.
- Optional upgraded flame-retardant EPS available for stricter fire safety zones.
Lightweight & Structural Efficiency
- Low self-weight significantly reduces load on steel structure frames.
- Ideal for large-span warehouses, factories, agricultural greenhouses, and temporary buildings.
- Wind pressure and structural stability tested per international standards.
Precision Engineering
- Tight side-joint sealing prevents water infiltration.
- High flatness ensures clean, professional roof appearance.
