Fiber cement is a composite material made of Portland cement, cellulose fibers, and mineral fillers. When manufactured as a flat roofing sheet, it undergoes a high-pressure steaming process (autoclaving) that results in a material with remarkable dimensional stability and strength.
- Unmatched Fire Safety (A1 Fire Rated)
For high-rise developments and industrial hubs, fire compliance is non-negotiable. Most premium fiber cement sheets are A1 or A2-s1, d0 non-combustible, providing an essential safety barrier that traditional bitumen or plastic-based roofing cannot match.
- Superior Moisture and Corrosion Resistance
Unlike metal roofing, fiber cement does not rust or corrode in coastal or high-humidity environments. Furthermore, high-quality boards are engineered to prevent “sweating” or leaching, ensuring the sub-assembly remains dry and mold-free.
- Low Thermal Expansion
One of the biggest challenges in roofing is the expansion and contraction caused by temperature swings. Fiber cement flat sheets have a very low coefficient of thermal expansion, which reduces the stress on screws, anchors, and frame systems.
Technical Data Sheet (TDS):
Density: ≥1.2g/cm3 for high-impact resistance.
- Modulus of Rupture (MOR): Class 4 or 5 according to EN 12467 standards.
- Water Impermeability: No water drops on the reverse side after 24 hours.
- Surface Finish: Options include through-colored, UV-resistant coatings, or natural grey for industrial aesthetics.
