Keeping a greenhouse warm is one of the most critical yet challenging and expensive aspects of greenhouse management. However, solutions exist to address this issue effectively. One of the widely adopted methods is double-layering the plastic on the walls and roof of the greenhouse. In this article, we explain how to apply this method and discuss how to purchase and price double-layer greenhouse plastic.
How to Purchase Double-Layer Greenhouse Plastic
At Keyhan Plastic, you can customize your desired double-layer greenhouse plastic based on dimensions, additives, thickness, color, and other specifications. One of the significant advantages of purchasing from Keyhan Plastic is the pre-sale and post-sale support and consultation provided to customers. This allows you to conveniently select and purchase greenhouse plastic tailored to your greenhouse and its surroundings.
Double-Layering Greenhouse Walls
To double-layer the walls, start by attaching a wire approximately 20 cm away from the walls you plan to cover, running it from the top of the first column to the bottom of the wall. Secure the wire tightly. Next, drape the plastic edge over the wire, fold it slightly, and fix it in place using staples or another suitable method. You can secure the bottom of the plastic to the greenhouse wall by placing soil over it, ensuring a layer of air remains between the wall and the plastic. This air layer acts as insulation and prevents heat transfer.
Double-Layering Greenhouse Roofs
For this process, place the rolls of plastic perpendicular to the direction of the roof wires and stretch them across to the end of the greenhouse. Due to the presence of columns, gaps may appear between the rolls of plastic. You can connect the plastic sheets using staples to ensure they remain secure.
Advantages of Double-Layering Greenhouses
When double-layering your greenhouse, consider the following points:
Cost-Effective Solution:
Since the double-layered plastic is not exposed to external factors like wind or heavy wear and tear, thick plastic is unnecessary. Thin, lightweight plastic can be used to keep costs low.
Humidity Retention:
Double-layering traps all moisture within the enclosed area, significantly reducing airflow. Therefore, proper greenhouse ventilation is crucial to prevent plant diseases and damage.
Energy Efficiency:
Double-layering enables the creation of separate spaces within the greenhouse. For instance, you can create a small area for seed germination with a lower ceiling. This allows you to maintain a warm environment using minimal fuel and a small heater while controlling humidity efficiently.
Reducing Costs with Double-Layering
By implementing the double-layering technique for greenhouse walls and roofs, you can warm your greenhouse at a much lower cost. While the initial investment in double-layering may be slightly higher, it ultimately reduces energy consumption and operational expenses.
Features of Double-Layer Greenhouse Plastic
Purpose-Specific Design:
The second layer of greenhouse plastic is primarily used for reducing energy consumption during colder months, rather than withstanding external factors like wind. Therefore, high-thickness or heavy-duty polyethylene is unnecessary. Thin, lightweight, and wide plastic is recommended for cost efficiency.
Humidity Preservation:
Double-layering preserves the moisture within the enclosed space, making proper ventilation essential to prevent plant diseases or crop damage.
Proper Dimensions and Width:
Choosing appropriate dimensions for the plastic is critical for comprehensive coverage. Seamless and continuous coverage of the greenhouse with the first and second layers minimizes heat and energy loss, leading to better efficiency.
