In greenhouse construction, the 5+1 and 5+2 construction methods of PO film refer to the different construction methods of the roof or covering layer to protect plants or crops. Some frequently asked questions are listed below to help better understand the difference between them:
What is the main difference between PO film 5+1 and 5+2?
PO film 5+1 includes 5 layers of material and 1 layer of PO film, while PO film 5+2 includes 5 layers of material and 2 layers of PO film, in which a layer of PO film is added in 5+2.
What are the different applications of PO film 5+1 and 5+2 in greenhouse construction?
PO membrane 5+1 is usually used in general greenhouse construction, providing basic waterproofing and protection functions. PO film 5+2 is used when there are higher requirements for waterproof performance and durability.
What is the impact of adding a layer of PO film on greenhouse construction?
The addition of a layer of PO film can improve the waterproof performance, increase the sealing between the layers, improve the insulation effect, and also increase the overall durability and anti-wear ability.
What factors need to be considered when choosing a PO membrane 5+1 or 5+2?
Factors such as the needs of the plant or crop, requirements for temperature, humidity and protection, budget constraints, and local climatic conditions need to be considered.
What is the difference in the difficulty and cost of construction of PO film 5+1 and 5+2?
Generally speaking, PO film 5+2 will increase the construction difficulty and cost compared to 5+1, because additional materials and construction steps are required.
By understanding these common problems, you can better understand the application and difference of PO film 5+1 and 5+2 in greenhouse construction, so as to make a more suitable choice.
