Greenhouse Construction and Covering Materials
Greenhouses are constructed with iron, wood, plastic materials, and the materials that have light and heat energy permeability, such as glass, polyethylene, polycarbonate, on the construction that is mostly made with the preference of iron.
Points to be considered during the supply of greenhouse building materials:
When we consider greenhouse building material as greenhouse construction material and greenhouse coating material, firstly, materials that are suitable for production and the current geographical conditions of the region should be selected, and the selected material should be light and robust, it should be easy to repair and maintain, and it should be supplied from certified companies that show that the selected material has the required standards. It should be displayed.
Greenhouse construction material:
If we consider wood and plastic at first, plastic pipes or wooden materials are used in terms of low accessibility and cost in small-scale greenhouses set up in extensive (traditional) agriculture or hobby purposes. Iron construction is preferred in professional greenhouse production with a large production volume and due to its low cost and low maintenance in the long run.
Materials known as greenhouse iron are construction elements that are shaped by giving certain properties to the steel and generally include galvanized steel which is highly resistant to corrosion and requires less maintenance.
Box profiles: profiles used in square or rectangular props or lovers.
Pipe profiles: Pipe profiles: They are hollow profiles with cylindrical shape and are generally used in tunnel greenhouse or gothic greenhouse construction
T, U and L Profiles: These are profiles that are used for different purposes in different places that take the shape of T, U and L according to their profile and have different strength values.
Greenhouse coating materials:
The materials we call greenhouse coating materials are generally glass, polycarbonate or polyethylene. It may be possible to cover the walls and roof of a greenhouse with different materials. This is entirely dependent on current climatic conditions, budget, and preference, but when choosing greenhouse coating material, the material that will meet these conditions at the most optimal point for the current production should be selected by looking at the light transmittance, the climate's suitability and durability, heat transmittance, ultraviolet light transmittance, and wear resistance.
Glass is a material that is highly resistant to deterioration and rust, transparent, water and air permeable, but highly fragile, affected by sudden temperature changes.
Polycarbonate is a light and durable plastic material that is easy to shape and provides insulation, which can be found in different shapes and chemical properties.
Polyethylene are plastic materials that are more affordable, but less resistant to glass and polycarbonate, resistant to external conditions.
In summary, planning should be done in the selection of greenhouse materials in order to produce at a low cost in the long run and to keep the greenhouse life long while getting maximum efficiency from the production.
