In gardening, greenhouses are considered one of the most effective adaptations... With their help, it is possible to get earlier harvests, cover plants that are not resistant to frost and even have fresh greens in the cold season.
At the same time, it is not necessary to spend money on the purchase of a ready-made greenhouse; it is quite possible for an ordinary gardener to build such a structure.
What are the benefits of a greenhouse?
Installing a greenhouse on a garden plot allows you to solve the main a problem for any gardener: discrepancy between the climatic requirements of the grown plants and the weather in fact. Heat in the greenhouse volume appears under the influence of sunlight penetrating through the translucent walls and heating the inner volume.
Cultivation facilities of this type are useful in solving problems such as:
- hardening of plants before planting in open ground;
- growing greenery from seeds in early spring and late autumn;
- winter storage of perennial plants that are sensitive to sudden changes in temperature, etc.
Accordingly, a lightweight greenhouse can facilitate growing absolutely all types of plants that are traditional for the gardens of our strip and fit into such a structure with their dimensions. At the same time, there will be no need to engage in serious construction. The very idea of a greenhouse involves the use of lightweight and quick-assembly structures.
Polycarbonate: pros and cons
As one of the types of plastic, polycarbonate can be produced in a wide variety of forms. The most widespread are monolithic and cellular... However, for gardening, monolithic polycarbonate is of little use, since it retains heat poorly.
Cellular option is characterized by such dignity, as:
- excellent thermal insulation due to the air-filled structure
- light weight
- good light transmission
- impact resistance
At the same time, there are also limitations:
- quick failure due to improper installation
- good ventilation is needed in warm weather
- sheets of material change geometry when heated
If a do not violate technology work with cellular polycarbonate, then all problematic issues cease to matter.
DIY construction recommendations
First of all, it is worth deciding on location the buildings. The following points will be of greatest importance in the manufacture of a polycarbonate greenhouse with your own hands:
- Orientation from west to east... This will maximize the amount of incoming sunlight.
- The internal atmosphere will be very humid, so you should carefully choose material for the frame greenhouse for cellular polycarbonate. Ideally, it should be a high quality mounting metal profile, with serious anti-corrosion protection.
- The dimensions of the polycarbonate greenhouse should be multiples of standard dimensions sheets (210 × 600 cm). This will make it easier to cut and reduce waste.
- The form structures. If the height does not exceed 1-1.5 m, then it makes no practical sense to build a semicircular greenhouse on arched arcs. The temperature in it will differ little from the outside temperature, because strongly curved polycarbonate begins to reflect most of the radiation back into space. Therefore, a greenhouse with flat walls and a roof is more rational.
- You can strengthen a building not only by strengthening its structure, but also correct location... So, if you adjoin a greenhouse to the south side of a house or other serious structure, then it will be protected from gusts of wind.
How to build a polycarbonate greenhouse with your own hands?
Manufacturing technology can be divided into several stages.
Stage 1. Drawing up a drawing.
Given the original size of the polycarbonate sheet, it is convenient to divide it into four parts dimensions 210 × 150 cm.It follows that it will be easiest to build a greenhouse with walls either 420 × 150 cm or 210 × 150 cm.Taking into account the height of the foundation of 20 cm, the total height of the greenhouse will be 170 cm, excluding the distance to the ridge.
Stage 2. Preparation of material and tools.
To work, you will need the following:
- Cellular polycarbonate (4-6 mm thick)
- Silicone sealant
- Mock-up tape for waterproofing joints
- Metal mounting profiles.
- Metal scissors
- Self-tapping screws
- Sections of a metal pipe with a diameter of 40-50 mm and a length of about 1000-1300 mm
- Garden drill
In addition, you will need work clothes and Remedies.
Stage 3. Erection of the foundation.
The total mass of the greenhouse can reach several tens of kilograms. Therefore, you cannot do without a reliable foundation. It will be needed for anti-sailing.
The simplest and most effective foundation for a greenhouse, it represents four metal pipes dug in at the corners of the structure. By using a drill, you can simplify the work. It is necessary to deepen the "piles" of the foundation 80-90 cm, leaving 20 cm above the ground for fastening the structures.
IMPORTANT. Before installing foundation pipes in wells, it is recommended to cover them waterproofing (bituminous mastic or at least paint).
Stage 4. Assembling the frame for one wall.
It will be easier to avoid mistakes if the walls of the greenhouse erect consistently... To begin with, a metal mounting profile is cut and cut. From the obtained with the help of self-tapping screws, a frame is formed for one wall. Next, it is screwed with self-tapping screws to the already finished foundation.
Stage 5. Cutting polycarbonate and wall cladding.
According to the dimensions outlined in the drawing, a sheet of cellular polycarbonate is cut out and mounted on the wall of the greenhouse. Fasteners can be carried out two ways:
A strip of metal. In this case, the joint of two sheets is covered from above with a strip of aluminum tape. The tape is fixed to the frame with self-tapping screws screwed into its middle and passing between the polycarbonate sheets.
H-shaped profile. This profile is specially designed for such operations, therefore it significantly speeds up the work. The profile is fixed in the right place on the frame of the greenhouse, and then sheets of cellular polycarbonate are simply inserted into it.
IMPORTANT. It is necessary to cut and mount sheets of cellular polycarbonate in such a way that the internal cavities are located either vertically or at an angle to the horizon. This will ensure that trapped water is removed quickly and will extend the service life.
In any case, the joints of the sheets after installation must be processed silicone sealant... The lower part of the finished wall is sheathed either with a strip of metal or with a solid board treated with an antiseptic.
The rest of the planes that make up the greenhouse structure are formed by a similar sequence of actions. If the roof is planned not flat, but with slopes, then the frame will have to be complicated by complementing it rafter system.
Stage 6. Door installation.
The location of the door to the greenhouse is selected in advance. On the width of the door, two mounting profiles are installed vertically, acting as a door frame. It is to them that the hinges will be screwed.
The door itself can be made from cellular polycarbonate scrapsscrewed to a plastic base or wooden slats.
To build a greenhouse made of cellular polycarbonate with your own hands is an event that is quite affordable for a home craftsman. It is enough to understand the features of the material and have basic construction skills to achieve what you want.
