Introduction to Two Common Daylighting Tiles: FRP Fiberglass and PC Polycarbonate Daylighting Tiles

1. Comparison of Material Properties

2. Analysis of Core Advantages

Irreplaceable Merits of PC Daylighting Tiles

1. Safety Protection: Passes impact test (10× glass), suitable for hail-prone regions.
2. Optical Performance: Up to 90% light transmittance with uniform light distribution, ideal for high-demand scenarios such as greenhouse seedling cultivation.
3. Convenient Construction: Cold bendable to reduce installation joints.

Cost-performance Advantages of FRP Daylighting Tiles

1. Resistant to acid and alkali corrosion, applicable to chemical plants and other corrosive environments.
2. 30%–40% lower cost than PC tiles, fit for projects with tight budget.
3. Customizable profiles to match corrugated steel sheets.

3. Material Selection Guidelines

✅ Prefer PC Tiles if:

• High light transmittance is required (e.g., ecological agriculture)
• High impact resistance is needed (e.g., coastal typhoon zones)
• Flame resistance of Class B1 or above is mandatory (e.g., public buildings)

✅ Prefer FRP Tiles if:

• The project has strict budget constraints
• Chemical corrosion exists (e.g., electroplating workshops)
• Profile matching with existing corrugated steel panels is required

4. Key Acceptance Inspection Indicators

Mandatory Inspection Items for PC Tiles

1. UV coating thickness (≥50μm)
2. Whether burning drips carry flame
3. Low-temperature drop-weight impact test (-20℃)

Mandatory Inspection Items for FRP Tiles

1. Resin content (≥65%)
2. Number of fiberglass layers (≥3 layers)
3. Peel strength of weather-resistant film
