What materials are commonly used to build a garden greenhouse?
The construction of
garden greenhouses is an exciting project that will help to provide plants with ideal growing conditions, extend the growing season, and grow plants that require special conditions. The choice of greenhouse material is very important for its performance and function. Here are some commonly used greenhouse building materials that play an important role in the design and construction of greenhouses.
Cladding: the cladding of the greenhouse is important for light permeability, thermal insulation and durability. The most common options include glass, polycarbonate sheets, polyethylene films, and PTFE films. Glass has good light transparency, but it is expensive. Polycarbonate panels are lightweight, strong, and have excellent thermal insulation properties. Polyethylene film is economical, but it is replaced more often. Ptfe film is durable and uv resistant.
Structural materials: the structure of the greenhouse is usually made of metallic materials such as aluminum alloy or galvanized steel pipes. These materials withstand the weight of the cladding, are resistant to rust, and have sufficient strength and durability. Wood can also be used for greenhouse structures, especially small greenhouses for home use.
Fundamental materials: the greenhouse needs a solid foundation that supports the entire structure. The concrete foundation provides excellent stability, while the wood foundation is suitable for small greenhouses. The design and construction of the foundation is very important to ensure the stability of the greenhouse.
Insulation: Insulation is used to improve the thermal insulation properties of a greenhouse. These materials often include foam or double-layer films that reduce heat loss and reduce energy consumption.
Ventilation and shading: in the greenhouse, you need an appropriate ventilation system to control temperature and humidity, so that the plants are not too hot or too humid. Shade material allows you to adjust the intensity of light and protect plants from damage caused by excessive sunlight.
Accessories and sealing materials: the construction of the greenhouse requires a variety of accessories, such as screws, nuts and bolts, to ensure the stability of the structure. In addition, in order to maintain the airtightness of the greenhouse components, sealing materials such as sealants and tapes are used to connect, seal and secure the greenhouse components.
What are the environmental benefits of using a garden greenhouse?
A
garden greenhouse is an environmentally friendly tool that not only provides the ideal environment for plant growth, but also brings various benefits to the environment. Below are some of the positive effects of using a garden greenhouse.
First, the greenhouse in the garden extends the growing season. In cold climates, create a warm and controlled environment so that plants can continue to grow even in cold seasons. This will reduce dependence on imported food, reduce greenhouse gas emissions from food transportation and reduce the demand for limited resources.
Secondly, greenhouses can reduce the distance that food must be transported. When food is grown in greenhouses, it gets closer to consumers and reduces greenhouse gas emissions from transportation. This can create a more sustainable food supply chain and reduce our dependence on fossil fuels such as oil.
Thirdly, the irrigation system in the greenhouse is often more efficient than outdoors. This means that water resources are more accurately managed and water waste is less. This is very important to solve the problem of water shortage, especially in dry areas.
In addition, because the greenhouse environment is controlled, it is often the case that fewer pesticides and fertilizers are needed. It makes it easier to monitor and control pests and diseases in greenhouses, reducing the need for harmful chemicals and helping to protect local ecosystems.
Greenhouses also offer the possibility of maintaining and protecting the diversity of plants. Growing plants in greenhouses that are not suitable for the local climatic conditions can contribute to the conservation and protection of endangered plant species while maintaining plant diversity.
In addition, the greenhouse reduces soil erosion due to rainfall. Mulching materials reduce the direct contact of rainwater with the soil and help maintain soil fertility and health.
Finally, many greenhouses can utilize renewable energy sources such as solar and wind to meet their energy needs. This will reduce our dependence on fossil fuels and help reduce our greenhouse gas emissions.
