🧱 What Are Polycarbonate Roofing Sheets?
Polycarbonate roofing sheets are made from a strong thermoplastic material that is lightweight, transparent, and impact-resistant. Unlike traditional roofing materials, polycarbonate offers exceptional flexibility and can be molded into various shapes—making it ideal for curved roofs, skylights, canopies, and sheds due to its high impact resistance and UV protection.
🏭 Manufacturing Process
- Raw Material – Polycarbonate resin granules are used.
- Extrusion – The melted resin is passed through an extrusion die to form sheets.
- Cooling & Cutting – The sheets are cooled and cut into required sizes.
- UV Coating – A UV protective layer is applied.
- Packaging – Sheets are packed with protective films for transport.
🌟 Advantages / Benefits
- High Strength & Durability – Up to 200 times stronger than glass; highly impact resistant.
- Lightweight – Easy to transport and install, requires less structural support.
- UV Protection – Comes with a special UV coating that blocks harmful UV rays and prevents discoloration.
- High Light Transmission – Allows 80–90% natural light to pass through, ideal for daylight roofing.
- Temperature Resistance – Withstands extreme temperatures from -40°C to +120°C.
- Flexible Design – Can be bent easily for curved or dome-shaped roofs.
- Fire Resistant – Flame retardant and provides enhanced safety.
- Low Maintenance – Easy to clean and less prone to dust or moss buildup.

🧩 Types of Polycarbonate Sheets
- Solid Polycarbonate Sheets: Crystal-clear like glass but much stronger; ideal for skylights and architectural applications.
- Multiwall (Hollow) Sheets: Provide insulation and reduce heat, making them perfect for greenhouses and sheds.
- Corrugated Sheets: Wavy pattern ensures excellent water drainage; suitable for large roofing projects.
- Embossed or Textured Sheets: Add a decorative and stylish touch to pergolas or balcony covers.
⏳ Lifespan & Warranty
- Average lifespan: 15–25 years (with proper installation & care).
- Warranty: Usually 10 years against UV damage and discoloration.
🛠️ Installation Process
- Measurement & Cutting – Sheets are cut according to the roof size.
- Frame Preparation – Metal or wooden frame is made for support.
- Fixing – Sheets are fixed with self-drilling screws and rubber washers.
- Sealing – Joints and edges are sealed using silicone sealant.
- Protective Film Removal – The film is removed after installation.
