How to Choose Greenhouse Covering Materials?

There is no “best” greenhouse covering material—only the one that best fits your project. The right choice depends on climate conditions, crops, budget, and expected lifespan.

1. Main Types of Greenhouse Covering Materials

 PE Film (Plastic Film Greenhouse)

Features:

Light transmission: 85%–90% 

Lifespan: 3–5 years (high-quality film can last longer) 

Cost: Low 

Advantages:

Low initial investment, fast return 

Easy installation 

Suitable for large-scale projects 

Can use double-layer film for better insulation 

Disadvantages:

Needs replacement after a few years 

Lower resistance to strong wind and heavy snow 

Best for:

Vegetable crops (tomatoes, cucumbers, peppers) 

Entry-level or budget projects 

Warm or mild climates 

Polycarbonate Sheet (PC / Twin-wall Panel)

Features:

Light transmission: 80%–88% 

Lifespan: 8–10 years 

Cost: Medium 

Advantages:

Excellent thermal insulation 

Strong impact resistance (hail, wind) 

Suitable for areas with large temperature differences 

Disadvantages:

Higher cost than film 

May slightly yellow over time 

Best for:

Cold regions or high-altitude areas 

Berries (strawberries, blueberries), flowers, nurseries 

Projects requiring stable growing conditions 

Glass Greenhouse

Features:

Light transmission: 90%+ (highest) 

Lifespan: 15–25 years 

Cost: High 

Advantages:

Maximum light for higher yields 

Strong and durable structure 

Ideal for modern, automated greenhouses 

Attractive for agri-tourism 

Disadvantages:

High initial investment 

More complex installation and maintenance 

Best for:

High-value crops and export-oriented farming 

Smart/automated greenhouse projects 

Large-scale commercial agriculture
