Farmers build an arched greenhouse, which is one of the common types of shaping the roof of these structures, for various reasons, which we will introduce in this article.

A greenhouse is a covered space that provides suitable conditions for growing plants by adjusting the temperature and other important factors for the growth of plants. These structures are placed in different categories based on several factors such as the type of structure or its appearance.

Farmers build an arched greenhouse, which is one of the common types of shaping the roof of these structures, for various reasons, which we will introduce in this article. So stay with us.

What is an arched greenhouse?

As it is clear from the name of this greenhouse, its roof resembles a tunnel with a semicircular curve. Of course, the term tunnel greenhouse is used for any type of space under the ship with a long and horizontal appearance similar to a tunnel, whose roof can have different shapes.

Most of the tunnel greenhouses in our country have an arched roof, the dimensions, height, material of the skeleton and the material used to cover the skeleton are different in different regions and according to the type of seed or available cost.

What are the reasons for building an arched greenhouse?

Various reasons may be involved in the farmer's decision to choose the type of greenhouse, which are usually referred to as the benefits of farming in this type of space and include:

These types of greenhouses are compatible with different climates around the world.
The arched roof of the greenhouse is suitable for growing all kinds of agricultural products.
It is very easy to build this type of greenhouse and farmers can use all kinds of available materials to frame the structure according to its dimensions or height.
The skeletons, whose different parts are connected to each other with bolts and nuts, have high resistance, and most of the arched greenhouses are made with this method of connection.
Curved roofs absorb more solar energy than flat roofs.
The cost of building an arched greenhouse is lower than other types such as a dome.
The amount of air circulation in this type of greenhouse is high due to the presence of sufficient space, as a result, more amount of CO2 reaches the plants and their efficiency is higher.
The curved shape of the greenhouse causes the air temperature to be the same in different parts of the greenhouse and the convection flow to be carried out quickly. The result of this process is the reduction of heating or cooling energy consumption.
It is possible to build this type of roof for all greenhouses with minimal space and large area.
The simplicity of building this type of roof has made it easy for inexperienced people to build a home greenhouse in winter.

Weaknesses or disadvantages of the arched greenhouse

In addition to the advantages of building an arched greenhouse, choosing this type of roof includes the following disadvantages:

Usually, these types of roofs are less resistant to wind, so they are not the best choice for windy areas.
In arched greenhouses with plastic covering, sometimes the highest point of the roof is flat, which may lead to some precipitation remaining on this point. Failure to direct rains downwards in the arched greenhouse leads to problems such as the weight of the roof, its dripping, or the reduction of the structure's resistance.
Most arched greenhouses are not well ventilated due to high air flow, which farmers can solve by installing ventilation devices or creating windows.

final word

Building an arched greenhouse is considered the best option for farmers who do not have a large amount of capital and are looking for a suitable structure for growing different plants. In this article, after introducing this type of roof, we explained its advantages and disadvantages.
