🏛️ What are GRC Fins?
GRC Fins (Glass Reinforced Concrete Fins) are vertical or horizontal facade elements used to provide sun shading, privacy, and aesthetic appealto buildings. They are lightweight, durable, and highly customizable, making them ideal for modern architecture, villas, commercial spaces, and institutional projects.
📜 History of Fins in Architecture
Architectural fins have been used since the mid-20th century as functional sunshades and design elements in modernist architecture. They became popular for their ability to control light, improve energy efficiency, and add rhythmto facades.
With the advent of Glass Reinforced Concrete (GRC), fins can now be produced in custom shapes, sizes, and textures, combining functionality with modern aesthetics. Today, GRC fins are a preferred choice for urban facades, institutions, commercial complexes, and residential projects.

Material Comparison - Fins
| Feature | GRC Fins | Aluminium Fins | Wooden Fins | Steel Fins |
|---|---|---|---|---|
| Lifespan | 50+ years with minimal wear | 30-40 years (prone to denting) | 10-15 years (susceptible to decay) | 40-50 years (can rust if not treated) |
| Maintenance | Very Low – weather & fire resistant | Moderate – prone to oxidation | High – termite & moisture protection needed | High – anti-rust treatment required |
| Cost/m² | ₹2000-4000 (affordable & durable) | ₹4000-6000 (expensive) | ₹1500-2500 (cheaper but less durable) | ₹3000-5000 (costly & heavy) |
| Weight | Lightweight – easy to install | Very light but less rigid | Light – but weak over time | Heavy – requires strong structure |
| Design Flexibility | Highly customizable (shapes, textures, patterns) | Customizable but limited textures | Custom designs possible but not durable | Limited – requires heavy fabrication |
