Prefabricated Double-Film Arch Solar Greenhouse

The Prefabricated Double-Film Arch Solar Greenhouse combines the weather-handling characteristics of a curved roof with the thermal benefits of a two-film covering system. The inner and outer films are supported by separate arch frames, creating an air-insulating layer between them to slow heat loss during cold periods.

Compared with a conventional single-film arch greenhouse, the supplied product description states that the double-film structure can improve heat retention by approximately 35%–45%. This makes the greenhouse suitable for areas with frequent frost and large differences between daytime and nighttime temperatures.

Five Practical Design Features

Double-film Air Insulation

The two film layers form an enclosed air space between the inner and outer coverings. This additional insulation layer helps reduce the penetration of cold air and slows nighttime cooling, providing better protection against frost for overwintering crops.

• Two independent arch frame layers
• Two greenhouse film layers
• Enclosed air-insulating space
• Improved nighttime heat retention
• Independent inner and outer film replacement

Curved Roof for Rain and Snow

The smooth arch roof reduces flat areas where snow can remain and allows rainwater to drain along the curved covering. This design is intended to reduce snow accumulation and is well suited to regions where rain and snow occur frequently.

The actual performance in severe weather depends on local snowfall, wind conditions and structural design, so greenhouse specifications should be matched to the installation environment.

Solar Heat Collection

The Prefabricated Double-Film Arch Solar Greenhouse retains the solar heat collection principle of a solar greenhouse. Its curved front structure provides the main light-receiving area, while the rear wall helps retain heat within the greenhouse after daylight hours.

This combination is intended to reduce rapid temperature changes between day and night and provide a more stable growing environment for overwintering crops.

Prefabricated Assembly Without Welding

Standardized structural components are prefabricated before shipment and assembled with bolts and connection fittings on site. The main installation process does not require field welding, making the structure easier to organize in overseas locations where welding equipment or specialized workers may not be readily available.

• Factory-prepared standard components
• Bolted and fitting-based assembly
• No on-site structural welding
• Modular packaging for overseas transportation

Lightweight Modular Construction

The arch frame can be divided into sections for transportation and stacked during packing. This modular format helps make better use of container space and simplifies handling, installation and later component replacement.

Covering and Growing Environment

The double-film structure can be configured with anti-fog and anti-drip film characteristics to help reduce condensation and water droplets inside the greenhouse. Proper ventilation remains important, particularly in humid growing regions, and automatic ventilation film systems or circulation fans can be added according to the project configuration.

The greenhouse is intended for protected cultivation of off-season vegetables, flowers, nursery plants and other crops that require improved winter protection.

Configuration Reference

Equipment Options

The Prefabricated Double-Film Arch Solar Greenhouse can be configured with supporting systems according to the climate and crop requirements. These systems are selected individually according to the project rather than requiring a fixed package for every installation.

• Electric thermal blanket rolling system
• Automatic ventilation film system
• Air circulation fans
• Water and fertilizer integration equipment
• Basic heating equipment
• External shading system
• Temperature and humidity monitoring
• High-efficiency drainage system

Suitable Applications

The greenhouse is intended for small and medium-sized agricultural projects in temperate and cold regions where winter heat retention, snow handling and installation simplicity are important.

• Off-season fruit and vegetable cultivation
• Flower overwintering cultivation
• Fruit and vegetable nursery bases
• Family farms
• Small and medium-sized energy-saving agricultural projects
• Growing projects in areas with frequent rain and snow

Adaptable Greenhouse Layout

The greenhouse can be configured for different sites by adjusting arch spacing, span and overall length. This provides flexibility for smaller farms as well as medium-sized cultivation projects and can also accommodate irregular plots and sloped land according to the project layout.

For connected greenhouse projects, the structure can be planned together with working paths, ventilation equipment and other supporting systems to match the actual growing arrangement.

Export and Installation Support

Ruize prepares the arch frame and related components as standardized modules before shipment. The sections can be stacked for export packing, helping reduce transportation space and simplify container loading.

As a manufacturer supplying overseas greenhouse projects, Ruize can provide assembly drawings, step-by-step installation videos and technical materials. The modular structure is designed around bolt and fitting connections, allowing ordinary workers to complete the main assembly with the supplied installation guidance.

Maintenance and Component Replacement

The double-film structure uses separate inner and outer coverings, so one film layer can be replaced without replacing the other. Standardized frame fittings also make later maintenance and component replacement more straightforward.

Routine checks should cover the greenhouse film, frame connections, ventilation components, drainage system and other installed equipment, especially before the winter growing season.

FAQ

Does the double-film structure take up much more space during shipping?

The arch frame is divided into sections and stacked during packing. This modular approach is intended to improve container-space utilization and make the greenhouse suitable for overseas batch shipment.

Will the double arch frame affect air circulation inside the greenhouse?

The double-frame structure provides separate support for the two film layers. Ventilation can be managed through the automatic ventilation film system and air circulation fans included in the optional configuration.

Can the greenhouse be used in rainy and humid regions?

Yes. The curved roof supports rainwater drainage, while suitable anti-fog and anti-drip film can help reduce condensation and water droplets. Ventilation and drainage should be configured according to the local humidity and rainfall conditions.

Can the greenhouse be installed on irregular or sloped land?

Yes. Arch spacing, span and length can be adjusted according to the site. The final greenhouse layout should be planned around the actual landform and available installation area.

Can a team without greenhouse installation experience assemble it?

The main structure uses prefabricated components and bolt-based assembly without field welding. Ruize can provide installation drawings, step-by-step videos and technical materials to support the assembly process.
