Product Description

The Sainpoly Polycarbonate greenhouse is aimed at the global commercial planting market, and its structure can withstand a snow load of 0.8KN/㎡ and strong winds of level 12, with a design life of over 20 years. In terms of insulation performance, an integrated solution of double-layer solar panels, internal insulation curtains, and a reserved heating is adopted, which can stabilize the temperature above 10 ℃ at night in winter and provide sufficient light transmission during the day, effectively addressing winter planting pain points such as low temperature, weak light, and high energy consumption. The service scope includes climate adaptation design, factory customized production, and on-site installation and commissioning, providing one-stop technical support.

Application and Solutions

Extremely cold in winter，conventional greenhouse vegetable crops will experience irreversible freezing damage.

Double-layer Thermal Insulation Structure

8mm double-layer hollow polycarbonate hollow panel+insulation curtain+heating interface, using double-layer hollow polycarbonate hollow panel structure, the internal air layer forms an efficient insulation layer, combined with the internal insulation curtain, the insulation rate can be increased by more than 40%, effectively blocking extreme low temperature intrusion.

Snow-resistant Steep Truss Roof

Effectively avoids snow collapse rosks truss+steep roof design, with enlarged main skeleton section and high-strength bolt connections at nodes. The roof is designed as a steep arch with a snow load design value of 0.32-0.8KN/㎡, and can be upgraded to higher snow load specifications.

High-transmittance Supplemental Lighting

Short light exposure time, slow vegetable growth, high light transmittance polycarbonate panel+optional LED fill light system. The polycarbonate panel uses high light transmittance anti-drip and anti-fog panel, with a light transmittance of up to 90%. It is equipped with LED plant fill light, and the effective light exposure time can be extended to more than 14 hours.

Zoned Energy-saving Heating System

High energy cost. Double layer hollow solar panel insulation+zone control, adopting a Double-layer hollow polycarbonate panels structure, using the hollow layer of the board to form a natural insulation barrier, and combining with the zone control system to independently adjust the heating power according to the zone. Compared to traditional single-layer film greenhouses, it can reduce energy consumption by more than 35%.

FAQ

Q: What is the insulation performance of this Polycarbonate Panel vegetable greenhouse? What's the lowest temperature it can withstand?

A: Equipped with 8mm/10mm double-layer hollow polycarbonate sheets, thermal insulation curtains and auxiliary heating systems, it can adapt to the extreme low temperature of -35℃ outdoors, and the indoor temperature can be stably maintained above 10℃, fully meeting the needs of off-season vegetable planting in northern areas.

Q: What is the Wind and Snow Load Bearing Capacities of the polycarbonate sheet greenhouse? Is it suitable for windy/snowy areas?

A: The standard configuration has a snow load resistance of 0.35kN/m² and wind load resistance of 0.35kN/m², which can be upgraded to 0.8kN/m² according to the local climate. The frame adopts hot-dip galvanizing process, which is fully suitable for extreme climate areas such as strong wind and heavy snow.

Q: What is the light transmittance of the Polycarbonate Panel? Will it affect crop photosynthesis?

A: The light transmittance of double-layer Polycarbonate Panel can reach 80%-85%, and the light enters the greenhouse in a diffuse way, which can avoid strong light burning crops, reduce indoor shadows, and make crops receive more uniform light, which is very suitable for planting leafy vegetables, flowers and other crops.

Q: Do you provide installation services? Is remote guidance feasible?

A: We provide two modes: ① Send technicians from the headquarters for on-site guidance;
② Provide detailed installation videos and manuals, with full remote assistance, and installation can be completed smoothly even for beginners.

Q: Does your Polycarbonate Panel greenhouse comply with EU standards?

A: Yes. We have CE certification, and steel, polycarbonate panel, sealants, etc. all comply with relevant EU standards, and can assist customers to pass local acceptance.

Q: Can I only purchase Polycarbonate Panel and frames and assemble them by myself?

A: Yes. All components are pre-processed, numbered and packed in the factory, with installation drawings attached, supporting DIY assembly. We can also provide installation training videos as needed.
