Overseas Multi-scene Engineering Case | Asbestos-Free Fiber Cement Board (South America & Africa Dedicated)

Project Name: Indoor & Outdoor Decoration Works for Overseas Hotels, Office Buildings, Shopping Malls and Schools

Project Location: South America & Africa. The products adapt perfectly to local harsh climatic conditions, including intense solar radiation, heavy rainfall, high air humidity, coastal salt fog, and large day-night temperature differences.

Applicable Buildings: Commercial and public buildings such as hotels, office buildings, commercial complexes and educational institutions.

Export Product: Asbestos-free fiber cement board (CE certified, fully compliant with international customs clearance and local construction acceptance criteria)

Detailed Technical Parameters

Standard Size: 1220*2440mm

Product Specifications:

• Medium Density: 1.25–1.35g/cm³, thickness 3.5–12mm

• High Density: 1.35–1.55g/cm³, thickness 5–30mm

Supporting System: Fiber cement board matched with hot-dip galvanized light steel keel. Suitable for both indoor and outdoor applications, featuring stable structure, superior rust resistance, aging resistance and deformation resistance.

Selection Guidelines

1. Density Selection Guidelines

Medium Density Board: Features smooth surface and cost-effectiveness, exclusively for indoor dry areas. Ideal for indoor ceilings, conventional partition walls, wall base courses and curved decorative substrates, meeting basic indoor requirements for fire resistance, moisture resistance and structural stability.

High Density Board: Boasts compact core, high strength, excellent impact resistance and weatherability. Suitable for all outdoor environments, as well as indoor humid zones, heavy-duty partition walls and key fireproof areas. It resists intense sunlight, rain erosion and salt corrosion, with no cracking, mildew or decay during long-term service.

2. Thickness Selection Guidelines

• 3.5–9.5mm (Thin Board): Lightweight and flexible for cutting and bending. Perfect for indoor special-shaped decorations, arc substrates, partial wall leveling and light-duty ceilings, only applicable to dry indoor conditions.

• 10–12mm (Medium-Thick Board / Main Specification): Universal for indoor and outdoor use. Medium density for standard indoor ceilings and partition walls; high density for kitchen & bathroom humid areas, fireproof partitions, balconies and light-duty outdoor ceilings.

• 15–30mm (Thick High-Density Board): Designed for heavy-load and extreme working conditions. Suitable for exterior wall substrates, open-air canopies, coastal and sandstorm-prone areas, and steel structure partition panels, delivering high strength, outstanding weather resistance and low maintenance costs.

General Application Scenarios

Indoor Application: Medium density boards are adopted for dry indoor areas to ensure flat finishing and cost efficiency. 10–12mm high density boards are applied to humid and fire-risk areas including kitchens, bathrooms, utility rooms and electrical shafts, providing reliable moisture resistance, flame retardancy and structural stability.

Outdoor Application: Only high density boards are permitted for outdoor use (medium density boards are not allowed outdoors). 10–12mm boards for conventional outdoor enclosures; 15–20mm boards for exterior walls and canopies; 25–30mm thick boards for coastal salt fog, severe sandstorm and heavy-load structures to withstand harsh outdoor climatic erosion.

Specialized Applications by Building Type

Hotel Projects

3.5–12mm medium density boards are used for ceilings and partition walls of guest rooms, lobbies and corridors, ensuring smooth finishing and efficient batch construction. 10–12mm high density boards are applied in kitchens, bathrooms and other humid zones. 10–20mm high density boards are adopted for exterior walls, balconies and canopies, offering excellent UV and water resistance to minimize daily maintenance.

Office Building Projects

8–12mm medium density boards are selected for office ceilings, partition walls and wall base courses, enabling efficient construction and neat overall appearance. 12mm high density boards are used for equipment rooms, fire passages and electrical shafts, fully complying with overseas fire safety standards with stable and long-lasting performance.

Shopping Mall & Commercial Complex Projects

10–12mm medium density boards are used for dry areas such as shop partitions, atrium ceilings and public walls. High density boards are applied for equipment rooms, humid service areas, street-side exterior walls and open-air corridors. 15–25mm thick high density boards are used for exposed areas, providing superior impact resistance and salt fog resistance suitable for high-traffic commercial environments.

School Projects

8–12mm medium density boards are adopted for ceilings and partition walls of classrooms, dormitories and offices, which are eco-friendly, odorless and safety-compliant. 10–30mm high density boards are installed in humid and exposed areas including restrooms, open corridors, terraces and exterior walls, featuring collision resistance, wear resistance, moisture and crack resistance to adapt to high-frequency daily use in campus environments.

Core Product Advantages

Compared with traditional gypsum boards and wooden boards, fiber cement boards integrate waterproof, sunproof, fireproof, moistureproof and anti-corrosion properties, effectively solving common problems such as mildew, cracking and deformation of decorative materials in overseas harsh environments. All products are CE certified, ensuring smooth customs clearance and high acceptance rates for projects in South America and Africa.

Reasonable matching of medium/high density and different thickness specifications balances construction quality and project cost. With neat indoor decoration effect and superior outdoor weather resistance, the boards greatly reduce later maintenance costs, making them the optimal choice for indoor and outdoor decoration of overseas hotels, office buildings, shopping malls and schools.
