Common Types of Greenhouse Coverings
1. Plastic Covering (Polyethylene)
- Lightweight and cost-effective
- High light transmission (over 85%)
- Available with UV filters, anti-drip, and anti-fog additives
- Offered in single-layer or double-layer models (with air blower) for improved insulation
- Ideal for vegetable, fruit, and seasonal flower greenhouses
- Commonly used in temperate and tropical climates
Common Additives for Greenhouse Films
- Anti-UV: Protection against ultraviolet radiation (available in various concentrations such as 5%, 8%, 10%)
- IR: Infrared blocker to reduce nighttime heat loss and lower fuel consumption
- Anti-Drip: Prevents condensation droplets from forming on the inner surface of the film
- EVA: Enhances flexibility, tear resistance, and thermal properties
- Anti-Virus: Minimizes transmission of pathogens by creating optimal light spectrum and reducing pest and disease activity inside the greenhouse
- LD: Ensures even light distribution and prevents leaf burn
2. Polycarbonate Sheets (Twin-Wall or Multi-Wall Panels)
- Extremely durable (10 years or more)
- Excellent resistance to impact and environmental conditions
- Good thermal insulation
- Allows light transmission with diffusion properties
- Ideal for modern industrial greenhouses
- Suitable for projects that require stronger and longer-lasting covering materials
3. Greenhouse Glass
- Excellent light transmission (90% or higher)
- Attractive appearance with long-lasting durability
- Resistant to temperature fluctuations
- Used in luxury greenhouses, research centers, and ornamental flower production
- Best suited for stable climates without extreme hail conditions
