Polycarbonate Sheet vs Fiber Sheet: Which Is Better for Roofing & Sheds in India (2026)?

Planning a car parking shed, terrace cover, or balcony roof? Here's an honest comparison of strength, cost, and light transmission to help you choose.

From car parking sheds to terrace covers and balcony roofs, Indian homes and societies rely heavily on translucent roofing sheets — and the two most common options, polycarbonate and fiber (FRP), perform very differently over time. Here's what actually matters before you buy.

Polycarbonate vs Fiber Sheet: What's the Real Difference?

Polycarbonate sheets are engineered plastic sheets, often multi-wall or corrugated, known for high impact strength, UV protection layers, and clear light transmission. They're widely used for car parking sheds, greenhouse roofing, and skylights.

Fiber sheets (FRP - Fibre Reinforced Plastic) are corrugated sheets made from resin-bonded fibreglass, commonly used for cost-effective roofing over sheds, warehouses, and utility areas. They're lighter on the budget but generally less durable under UV exposure.

Polycarbonate vs Fiber Sheet: Head-to-Head Comparison

Feature	Polycarbonate Sheet	Fiber (FRP) Sheet
Impact Strength	Very high, resists hail & falling debris	Moderate, can crack under heavy impact
Light Transmission	Clear, consistent, does not yellow quickly	Yellows and dulls faster with UV exposure
Weight	Lightweight, easy to install on frames	Lightweight, similarly easy to handle
UV / Weather Resistance	Strong with UV-coated grades	Degrades faster without added coating
Lifespan	10-15 years with UV protection	5-8 years typical
Price (per sq ft)	₹70 – ₹180	₹45 – ₹90
Fire Resistance	Generally better fire-retardant grades available	Can be more flammable depending on grade
Best For	Car parking sheds, skylights, long-term roofing	Budget sheds, warehouses, temporary structures

Polycarbonate Sheet: Honest Pros and Cons

Advantages

Excellent impact resistance against hail and debris
Stays clear and transparent for longer
Better long-term UV stability
Longer lifespan reduces replacement frequency
Wide range of finishes: clear, tinted, multi-wall

Disadvantages

Higher upfront cost than fiber sheets
Premium UV-grade sheets cost more still
Can expand/contract with heat, needs proper fixing gaps
Lower-grade imports may not have real UV protection

Buying Tip: Always ask for the UV-protection layer specification when buying polycarbonate sheets — cheap, uncoated sheets yellow and become brittle within 2-3 years, losing the main advantage over fiber sheets.

Which Should You Choose, By Use Case?

Parking

Car Parking Sheds

Polycarbonate is the stronger choice here, standing up to hail, branches, and years of direct sun exposure.

Terrace

Terrace & Balcony Roofing

Polycarbonate's clarity and durability make it ideal for covered sit-out areas that need to stay bright and leak-free.

Warehouse

Warehouses & Sheds

Fiber sheets offer a cost-effective roofing solution for large utility or storage structures with lower durability demands.

Temporary

Temporary Structures

For short-term coverage needs, fiber sheets deliver adequate protection at a lower budget.

Roofing Sheet Price in India — 2026 Guide

Type	Price Range (per sq ft)
Fiber (FRP) Sheet - standard	₹45 – ₹70
Fiber (FRP) Sheet - UV coated	₹70 – ₹90
Polycarbonate Sheet - standard	₹70 – ₹110
Polycarbonate Sheet - premium multi-wall/UV	₹120 – ₹180

Our Recommendation

For long-term structures like car parking sheds, terrace covers, and balcony roofing where durability and clarity matter, polycarbonate sheets are worth the higher upfront cost. For budget-conscious, shorter-term, or utility structures like warehouses and temporary sheds, fiber sheets remain a practical, cost-effective choice. Either way, always confirm the UV-protection grade before buying.

Frequently Asked Questions

Is polycarbonate sheet cheaper than fiber sheet? ▾

Fiber (FRP) sheets are generally cheaper upfront, typically ₹45 to ₹90 per sq ft, while polycarbonate sheets range from ₹70 to ₹180 per sq ft depending on thickness and UV protection.

Which is stronger, polycarbonate or fiber sheet? ▾

Polycarbonate sheets are significantly stronger and more impact-resistant than fiber sheets, making them better suited to hailstorms, falling branches, and high-traffic areas like car parking sheds.

Which lets in more light, polycarbonate or fiber sheet? ▾

Clear or translucent polycarbonate sheets generally allow better, more even light transmission than fiber sheets, which tend to yellow and become less transparent over time with UV exposure.

How long does each roofing sheet last? ▾

Quality UV-protected polycarbonate sheets typically last 10 to 15 years, while standard fiber sheets usually last 5 to 8 years before yellowing, becoming brittle, or leaking at the joints.

Which is better for a car parking shed roof? ▾

Polycarbonate sheets are generally the better choice for car parking sheds due to their higher impact resistance, better UV stability, and longer lifespan, despite the higher upfront cost.
