From Glass to Foil: Choosing the Right Greenhouse Covering — and Installing It Right

When it comes to greenhouse performance, the covering material plays a critical role in how effectively a growing environment supports crops year-round. Whether you’re building a small polyhouse or a large-scale glasshouse, selecting the right type of covering — and ensuring it’s installed correctly — directly impacts light transmission, insulation, durability, and long-term productivity.

At Agrikol Group, we specialize in assembling and covering greenhouses of all sizes and types across a wide range of climates. In this article, we explore the most common covering options and why skilled installation is just as important as the material itself.

Glass: Maximum Light, Maximum Lifespan

Glass greenhouses are the gold standard for commercial horticulture, especially in Europe. Glass offers:

  • Excellent light transmission (up to 90%)
  • Durability (can last 30+ years)
  • Resistant to UV degradation
  • Easy to clean and maintain

However, glass also requires a strong structure, proper sealing, and precision installation to avoid thermal losses and breakage.

Agrikol’s role: Our teams are experienced in handling and glazing thousands of square meters of glass — ensuring perfect alignment, secure fixing, and weather resistance, even on large-scale commercial projects.

Foil (Plastic Film): Lightweight and Flexible

Greenhouses covered with plastic film (foil) are cost-effective and adaptable. Often used in:

  • Seasonal or budget-conscious operations
  • Areas with mild climates
  • Shorter project life cycles

Modern multi-layer foils offer UV resistance, light diffusion, and thermal insulation, but they do degrade over time and require periodic replacement (typically every 3–5 years).

Agrikol’s role: We perform both new foil installations and foil replacement/renovation projects around the world. From proper tensioning to leak prevention, our team ensures your greenhouse remains sealed, efficient, and productive.

Polycarbonate or Rigid Plastic Panels: A Middle Ground

Polycarbonate panels provide a balance between glass and foil:

  • Good insulation properties
  • Shatter-resistant and safer than glass
  • Suitable for regions with harsh weather or hail

Installation must be carefully handled to maintain structural integrity and thermal performance.

Agrikol’s role: We offer expert assembly and panel fitting, ensuring no gaps, secure anchoring, and proper ventilation integration to avoid moisture buildup or heat stress.

The Importance of Skilled Installation

Even the best materials underperform if they’re not installed correctly. Improper covering leads to:

  • Heat loss and energy waste
  • Leaking, condensation, or structural damage
  • Reduced light for plants
  • Shortened lifespan of the covering itself

With Agrikol’s specialized teams, every covering — from foil to glass — is installed with precision, using tested techniques to ensure long-lasting, climate-efficient structures tailored to the local environment.

Built for Every Climate, Installed with Care

Having worked on greenhouse projects in France, Italy, Slovenia, Tunisia, the Netherlands, Japan, Australia, and beyond, Agrikol understands how climate impacts material performance. We help clients choose the right solution — and deliver reliable results in any region.

Conclusion: The Covering Counts — and So Does the Team Behind It

Choosing the right greenhouse covering is a strategic decision, but the quality of installation will determine whether that decision pays off.

Whether you’re building a high-tech glasshouse or a cost-effective poly greenhouse, Agrikol Group has the experience, technical know-how, and skilled professionals to bring your project to life — and make it last.
