HOW TO CHOOSE THE RIGHT POLYCARBONATE SHEET: COMPACT VS MULTIWALL VS CORRUGATED
Modern construction requires roofing materials that combine durability, natural daylight, heat control, and long-term performance.
Across Chennai and South India, builders, architects, and property owners are increasingly choosing polycarbonate roofing sheets for homes, commercial buildings, industrial sheds, and skylight applications.
But one important question remains. Which polycarbonate sheet is the right choice?
Understanding the differences between compact, multiwall, and corrugated polycarbonate sheets is essential before selecting a roofing solution.
Why Polycarbonate Roofing Sheets Are Growing in Demand
Traditional roofing materials often struggle in hot and humid climates.
Buildings across Chennai, Tamil Nadu, Karnataka, Kerala, and Hyderabad commonly face:
- Excess heat buildup
- Poor natural lighting
- Heavy rainfall exposure
- High electricity consumption
- Weather-related wear and damage
This is why polycarbonate roofing sheets from Lotus Roofings are becoming a preferred alternative.
They provide:
- UV protection
B. Impact resistance
C. Natural daylight
D. Lightweight installation
E. Weather resistance
However, different applications require different sheet types.
