The greenhouse in the country or in the garden allows the owner to harvest much earlier than from the beds on the open ground. In addition to the dignity of the structure can be attributed and a great duration of crop yields. That's why a lot of truck farmers decide to grow vegetables and greens in a greenhouse . Many acquire a ready-made structure for a considerable amount, by the way. But you can make a greenhouse with your own hands, which, of course, will significantly reduce material waste. And by the way, one of the important aspects is the coating material. Most often in this quality, the film is used - the material is cheap and convenient, and in some cases also durable. If you are thinking about how to cover the greenhouse frame and think about it, we will tell you which film is better for the greenhouse and which one to choose.
Film for greenhouses - how to choose?
In order for your future greenhouse to fulfill its tasks, the film must necessarily have the following properties, namely:
- waterproof;
- transparent;
- elastic;
- resistant to temperature;
- breathable;
- light scattering.
Undoubtedly, for this purpose a relatively strong polyethylene film is suitable, which is also the most affordable. But it can also be of different types, each with its own characteristics, as will be discussed below.
Types of polyethylene film for greenhouses
Of all the types of films that are sold on the market, really strong, only three types:
- reinforced;
- long-term;
- polyvinyl chloride.
Reinforced film for greenhouses is a very dense material with a special honeycomb inner frame (s) of polypropylene or fiberglass. Such a film, although strong (serving 2-3 years), but has a relatively low permeability.
Conventional polyethylene film for greenhouses and greenhouses is the cheapest option on the market. Serves such material no longer than one season, but is popular with summer residents for its economy.
Polyvinyl chloride film , apparently reminiscent of cellophane, is considered one of the most durable materials. Such material has a high light transmission characteristic - not less than 90%. In addition, a polyvinyl chloride film is capable of retaining more than 90% of infrared and more than 80% of ultraviolet radiation. This coating is suitable in cases where there is an intention to save on heating the greenhouse.
The perennial greenhouse film is a large group of materials for coating greenhouses of various types, most of which are made of polyethylene with various additives to improve properties. For example, the light stabilized film for greenhouses differs from the usual in that its composition includes special substances. Thanks to this additive, the material is UV resistant and therefore is destroyed more slowly due to sunlight. Its subspecies, black and white film for greenhouses, painted on one side in white, on the other - in black. Due to this, the black side absorbs solar heat, and the white side, on the contrary, reflects it. True, such a material is used as a coating of the surface of the soil in a greenhouse
Stabilized hydrophilic film allows you to get rid of such a phenomenon, characteristic of greenhouses, like the morning condensation on the inner surface of moisture. The resulting droplets of water simply flow down the film. In the antistatic multi-year film, the additive prevents the appearance of dust on the surface. Heat-retaining film retains heat due to the fact that due to the composition it does not pass infrared rays. Air-bubble film for greenhouses is a three-layer structure: the inner layer of air bubbles is surrounded on 2 sides by a smooth film. This design is water resistant and frost-resistant.
