Arched options began to supplant the classic look of the “house” greenhouse. And completely in vain. The wall of the arched building has a slope, and the angle formed at the surface of the earth cannot be planted with anything. In a greenhouse “house”, straight walls run vertically, which allows you to use every centimeter of usable area.
The shape of the structure of the greenhouse “house” is similar to a real building, but small in size. Traditionally it has a gable roof, which can consist of one or more parts, and straight-walled roofs. The entire structure is made of transparent material to make the most of the sunlight. Most often, the “house” has one or two doors, opening windows or a removable roof. The height is about 2 meters. This creates a good volume for the room and allows it to be used for climbing and vigorous plants. The place for the greenhouse is chosen illuminated and located on a hill so that precipitation does not flood the structure.
The constructions are ready-made. Manufacturers offer their product in various sizes and materials. Or you can build it yourself, using purchased or improvised means.
Advantages and disadvantages
A closed-type greenhouse “house” is an excellent solution for growing plants on a personal plot.
It has its own advantages and benefits, which are expressed in the following:
- the design is completely transparent and receives the maximum amount of light;
- has one or two doors, windows or a removable roof, which makes it possible to ventilate and regulate the temperature;
- the height of the greenhouse allows you to work in full growth and plant tall or climbing plants;
- if compared with an arch, then it is the straight walls that make it possible to rationally use the area and plant vegetables at their very base;
- “house” design is strong and reliable, it can withstand critical weather conditions;
- the gable roof has proven itself well, it does not accumulate snow and rainwater;
- greenhouse “house” can be made of different materials, the owner chooses it based on budgetary possibilities;
- overheated air rises upward, under the roof, and does not harm the plantation;
- for tall plants, the roof of the “house” can be brought out to the desired size;
- due to greenhouse conditions, the crop is harvested earlier than usual;
- Plants that are not in contact with external sediments and painful surrounding vegetation produce a healthier and better harvest;
- in greenhouses, plants are protected from insects, domestic animals and birds;
- the transparent greenhouse looks beautiful, airy and does not spoil the appearance of the site;
- the structure can be equipped with automatic irrigation, thermal drive, lighting;
- there is an opportunity to reduce the cost of the building if it is made from improvised material, for example, glass left after replacing windows;
- rectangular design details facilitate greenhouse installation.
There are also drawbacks to the greenhouse “house”: the design is expensive, and the glass and metal options are difficult to assemble, have many parts and are more weighty. Such greenhouses are installed on a foundation, so they cannot be quickly transferred to another place..
The glass structure is difficult to seal, resulting in heat loss. If polycarbonate is chosen for the coating, then a more expensive (6-8 mm) will be required due to the increased pressure on the roof.
What materials are greenhouses built from?
“House” consists of two main parts: frame and cover. The support is supported by durable material that can hold not only the greenhouse cover, but also snow on its surface. The walls and roof of the structure must be transparent.
One of the main parts of any greenhouse is the frame..
Different types of materials can participate in its creation..
- Metal. The structure is light and strong, but must have an anti-corrosion coating, otherwise it will deteriorate in a humid environment. For self-production of a metal structure, you must have a welding machine and welder skills.
- Wood. Such a frame is cheaper than a metal one, but it does not differ in durability. The wood should be well treated with antifungal and antimicrobial agents, it is also susceptible to rodent attack, aging and decay. But if you want to save money, and after replacing the windows, wooden frames with glass remained, then here – no options. The material available will make a beautiful glass-covered wooden greenhouse..
If the frame is built from new purchased material, then a 50×50 mm timber should be purchased, it will be needed for the frame and even thicker for the base.
- Plastic (PVC pipes). Such material is rarely used to create greenhouses, but rather for greenhouses. Plastic is lightweight, cheap, does not rot, does not corrode. But it does not tolerate high temperatures well, it can deform. This design will not protect against heavy loads. If it can withstand the weight of the greenhouse cover, it may break from snow drifts..
- Brick. Sometimes they build a base for a brick covering. This material does not corrode like metal, does not rot like wood, does not suffer from fungus and rodents. But it will no longer be possible to transfer such a greenhouse. In the future, you will have to solve problems with depleted soil..
The selection of covering materials for the construction of a greenhouse is the most important point..
With their help, you can achieve greater light transmission, thermal insulation, strength, reliability or a significant reduction in the cost of the project..
- Polyethylene coating – the cheapest and easiest option, but not quite the best in other respects. Its light transmission is much lower than that of glass. Thermal insulation also cannot be compared to polycarbonate or glass. It is easily susceptible to mechanical stress. For the “house”, you should choose a more durable polyethylene, but even in this case, the greenhouse will be temporary, used only during the season and assembled for the winter.
- Polycarbonate – a popular and optimal option for covering a greenhouse. It transmits light well and retains heat due to the voids in its structure. The material perfectly scatters the sun’s rays, but retains ultraviolet light, which can harm plants. Polycarbonate is able to withstand a load 200 times more than glass and is easy to assemble by yourself. Polycarbonate is much lighter in weight than glass and the base materials may not be overly reinforced. Such a “house” can be left for the winter, it can easily cope with the weather conditions.
- Glass – the material is expensive, heavy and fragile, so it is better to use it for a stationary greenhouse. The light transmission of glass has no competitors. If you cope with sealing or create an expensive greenhouse from custom-made glass units, the thermal insulation in such a room will also be at its best. Such “houses” have a wonderful indoor climate. Despite the fragility of the material, the greenhouse looks sturdy and reliable. It can also be a cheap project if assembled from old windows..
Choice of construction “house”
Having studied the quality and technical characteristics of materials, everyone decides for himself which greenhouse to build. Much depends on the requirements for it. If you need an inexpensive seasonal “house”, you can build a wooden frame and cover it with polyethylene. For a large stationary greenhouse, the frame is better made of metal or brick, and the covering is made of polycarbonate or glass. But most often they build “houses” of medium size from polycarbonate, and this is an option averaged over material capabilities. When choosing what to make a greenhouse from, one should take into account corrosion, decay, fungal infections of the material, as well as its resistance to stress. Considering options for ready-made “houses”, you need to pay attention to the roof, which is removable or opening, the presence of vents, so that in the future there will be no problems with ventilation.
It is better to prudently choose greenhouses that are able to equip themselves with automatic irrigation and thermal drive. Successful options include constructions made in full human height or with an opening top: they have a lot of air, you can easily turn around and straighten your back, they are suitable for both short and tall crops. The angle of the roof slope should be at least 30 cm, this will allow the snow to slide off easily.
How to build a greenhouse
Many decide to build on their own. To do this, you need to choose and prepare a place for the greenhouse, decide on the material, make drawings, calculations and get to work.
Drawings and calculations
In most cases, when building a greenhouse as a “house”, the calculations are not tied to the material (with the exception of carbonate), but they equip the interior space at their own discretion. The height of the building is chosen according to the height of the tallest member of the family – this concerns the door, and a sloping roof rises above it. The dimensions of the greenhouse will depend on the size of the beds and the internal passage, which must be sufficient to carry the cart..
The size of the greenhouse can be affected by the availability of a designated place on the personal plot, as well as the material capabilities of the developer.
Building a greenhouse yourself, you should pay attention to some of the nuances:
- taking into account the best option for the sun’s rays to enter through the coverings, it is better to place the greenhouse in length from north to south;
- it is good to have sandy soil under the fertile layer of the surface;
- for the greenhouse, you should choose a place where groundwater does not come too close to the surface, otherwise you will have to drain it from gravel or coarse sandstone;
- the ideal length of the building is up to 5 meters, if it turns out more, you will have to tinker with additional ventilation.
When choosing a material in the form of carbonate, you should take into account the standard sheet sizes, from these calculations, draw up a greenhouse scheme.
Those who do not have the time and desire to build a greenhouse on their own can purchase it on the market of domestic producers.
Russian companies produce them in different parts of the country:
- a greenhouse with the name “House” – in the Irkutsk region, it has a metal frame, equipped with two entrances and two ventilation windows, its dimensions: 3x2x2.1 m;
- the greenhouse “Delta” is produced by the Moscow company “Volia”, the frame is made of metal pipes, compact dimensions (1.1×2.5×2.2) allow you to transfer the structure to any place on the site;
- the greenhouse “Slava Lux” is produced in Nizhny Novgorod, it has reinforced rigidity, two doors, windows, a metal body, its dimensions are 2.8×2.2.
Gardeners can appreciate all the advantages of having a greenhouse on their personal plot and will never regret their purchase..
