The common covering materials used in greenhouses

The crucial part of greenhouse structure is the fixed covering material. Therefore, the covering material and its characteristics are one of the most important components of the entire greenhouse. Ideally, the covering material should have high light transmission, ability to prevent heat loss, durability, ease of installation, and affordability. Different crops have different environmental requirements, so different covering materials will be effective for different crops. As a professional greenhouse company, we will develop the most suitable solutions based on the specific requirements and environmental conditions of our clients.

    Our advantage

    The covering materials for greenhouses come in various types, with the four most common being:

    PEP film: Polyethylene film (PEP) is a common greenhouse covering material that is light, transparent, and weather-resistant, yet inexpensive.

    Polycarbonate: Polycarbonate provides excellent impact resistance, transparency, and thermal insulation, making it suitable for greenhouse structures that require stronger resistance to snow and insulation. It is considered one of the most advanced polymers in plastic applications, offering a combination of properties such as strength, light transmission, elasticity, lightweight, transparency, and a wide temperature range.The improved co-extrusion manufacturing technique incorporates a UV protection layer into the product, preventing peeling, wrinkling, cracking, or wear. This type of polycarbonate panel can maintain its light transmission even at high temperatures. The hard, transparent, corrugated polycarbonate panels have a visible light transmittance of 89%, completely block harmful UV radiation, have a high absorption rate for far-infrared, and are lightweight, making them easy to install. They also have separate protection against hail damage.

    Glass: Glass, as a traditional greenhouse covering material, offers high light transmission, aesthetic appeal, over 90% light transmittance, good insulation, superior heat resistance, UV protection, durability with a lifespan of up to 25 years, and a low coefficient of thermal expansion and contraction.

    Black and white film: Black and white films are primarily used for shading and temperature control within the greenhouse. The white side reflects sunlight to reduce internal temperature, while the black side absorbs heat radiated at night, elevating internal temperatures and inhibiting weed growth.
