🏠What is uPVC Roofing Sheet?
uPVC (Unplasticized Polyvinyl Chloride) roofing sheets are made from a strong and durable form of plastic that is rigid, lightweight, and weather-resistant. uPVC does not contain plasticizers — making it more robust and less flexible, ideal for roofing applications.
⚙️ Making / Manufacturing Process
uPVC (Unplasticized Polyvinyl Chloride) roofing sheets are made using high-quality PVC resin with stabilizers, UV absorbers, impact modifiers, and pigments.
Process:
- Raw materials are mixed in a high-speed mixer.
- The mixture is melted and passed through an extrusion machine.
- Sheets are shaped through molds to get the corrugated or flat design.
- They are cooled, cut, and finished to desired sizes and thicknesses.
- Finally, UV coating or protective layer is added for long life.

🔩 Installation Process
- Frame Preparation:
Prepare a stable roof frame using metal or wood. - Sheet Placement:
Start from the bottom edge of the roof and overlap sheets by 1–2 corrugations. - Fixing:
Use self-drilling screws with rubber washers to secure the sheets. - Sealing:
Apply sealant or silicone at joints to prevent water leakage. - Finishing:
Fix ridge caps, gutters, and side flashings to complete the roof.
