In contemporary architecture, building materials are expected to deliver not only aesthetics but also sustainability. Energy efficiency, environmental sensitivity, and longevity are now core criteria. In this context, Glass Fiber Reinforced Concrete (GFRC) stands out in facade cladding with both technical and environmental performance. Among Istanbul precast companies, Fibercast differentiates projects with eco-friendly and durable GFRC solutions alongside refined aesthetics.

1. Material efficiency and resource savings

• High strength in thin sections: Compared to conventional concrete, GFRC delivers high performance at lower thickness.
• Less raw material: Reduced cement, aggregate, and water consumption lowers natural resource use and carbon footprint.

2. Energy-efficient production

• Low-temperature curing enables energy savings.
• Minimized waste and recyclable raw materials in production.

3. Light weight = lower carbon emissions

• Fuel savings in transport and less heavy equipment on site accelerate installation and reduce energy use.

4. Long service life and low maintenance

• High resistance to freeze–thaw, UV, moisture, and fire; appearance retained for many years.

5. Recyclable and natural content

GFRC consists of glass fiber, cement, silica sand, and water. At end-of-life, panels can be crushed and used as secondary aggregate.

6. Contribution to green building certifications

GFRC supports LEED, BREEAM, and DGNB credits through energy savings, material optimization, and durability.

Bottom line: GFRC provides aesthetics, durability, and environmental benefits together; a sustainable mainstay for modern facades.

Thanks to its fully inorganic composition, GRC is non-combustible; it produces no smoke, toxic gas, or flaming droplets under fire. Classified as A1–A2 per European standards, it retains form and strength even above 800°C. This brings major advantages for high-rise buildings, hospitals, and public facilities.

Laboratory tests and performance

• No cracking or delamination after 2 hours at 850°C.
• Post-fire, only surface discoloration; structural integrity preserved.

GRC composition

Cement, fine aggregate, polymer modifiers, water, and alkali-resistant glass fibers (AR-glass).

• Glass fibers withstand roughly 800–1000°C.
• The matrix does not emit smoke or toxic gases; no dripping.

Fiber types in concrete (summary)

1. Glass fiber: High strength in thin sections, A1 non-combustible; ideal for facade panels and architectural details.
2. Steel fiber: Impact and fatigue resistance for industrial slabs and tunnels.
3. Polypropylene fiber: Reduces micro-cracking and spalling risk under fire.
4. Carbon fiber: Very high strength, corrosion-free; higher cost.
5. Basalt fiber: Chemical and temperature resistance; good for marine/industrial use.
6. Natural fibers: Low carbon footprint; sensitive to moisture.

Bottom line: The right fiber selection directly affects performance and economics. Fibercast GRC panels combine fire safety with design freedom.

1. Introduction

GRC is a composite that is both light and high-strength thanks to glass fiber reinforcement. It delivers aesthetics and functionality together and has been increasingly adopted. In Turkey it has been used since the 1980s; Fibercast started production in 1989.

2. Definition and composition

• Portland cement (binder), fine aggregate/sand, polymer modifiers, glass fibers.
• Incorrect proportions can cause cracking, breaking, or friability.

3. Advantages

• Lightweight: Reduces structural loads and eases transport of large panels.
• Durability: Resistance to cracking and impact.
• Aesthetic flexibility: Wide range of textures, colors, and geometries.
• Fire resistance: Non-combustible and temperature-resistant.
• Sustainability: Material optimization and long service life.

4. Applications

• Exterior facades, interior decorative panels, columns/balconies, sculptures and custom elements.
• Historic restoration projects to keep original looks with modern performance.

4a. Global use

• United Kingdom: Restoration and modern office facades.
• United States: Decorative facades and interior panels.
• Germany & Netherlands: Public and residential projects.
• Australia: Coastal buildings for light weight and durability.
• China & Japan: Large-scale commercial and cultural buildings.

5. Production and application

1. Mix design prepared.
2. Glass fibers dispersed homogeneously.
3. Molding by casting or spray-up.
4. Curing under controlled conditions.

6. Conclusion

GRC stands out for lightness, durability, and design flexibility. Its use in facades, decorative elements, and restoration is growing globally.
