Greenhouses made of glass and aluminum. How to build a greenhouse?

If you have your own house or cottage, it becomes necessary to improve the adjacent plot of land. Depending on the size of the land plot, except for a gazebo, a swimming pool and a children's playground, glass and aluminum hothouses are being built. Their purpose is to grow vegetables and greens on the plot.

Greenhouses, greenhouses and conservatories

Such structures can be made with their own hands using special sets or on an individual project. If the greenhouses and greenhouses are designed for growing early vegetable products or seedlings, the winter gardens are created for a comfortable rest or breeding of exotic plants all year round. Thanks to the innovations of designers, modern buildings impress with their originality, elegance, sophistication of architectural forms and a variety of configurations. Greenhouses and greenhouses can be made of film. Their main difference in size. During work, a person is inside a greenhouse, and care for greenhouse plantings is more time-consuming.

For the construction of such buildings more often use plastic, cellular polycarbonate or glass. The classical designs of glass and aluminum profile are quite comfortable and reliable.

Types of greenhouses

The facilities can be detached or attached to the wall of the house. The first walls are straight or inclined inward, and the roof is one-pitch, two-level or two-level. For small garden plots it is more reasonable to make wall constructions. Both small and large greenhouses are sometimes constructed using tubular frames made of steel or alloys and film coating. They are cheaper than glass, but inconvenient for operation. Each species has its own advantages.

Spacious greenhouses allow you to work indoors. They are a strong and reliable frame, covered with sheets of glass. One or more walls can be protected by boards or laid out of a brick to a certain level, taking into account the necessary illumination. Greenhouses, glazed to the level of the soil, can be covered with wooden shields for thermal insulation. The safety factor is different and depends on the available climatic conditions, for example, the strength and direction of the wind.

Other options

To rationally organize large-scale cultivation of crops, glass-and-aluminum hothouses are used, moving along rails. They are installed over planted plants of early maturation, such as salad. After a certain phase of development, the greenhouse is moved to the other end of the plot and planted seedlings of other crops. Salad for further growth and maturation remains in the open ground. The facilities can be of circular shape, multi-level with various ramps, block hexagonal.

Support structures are made of steel, duralumin or wood. Duralumin supports are light and strong, they can be given any shape. On the metal frame, condensate is easily collected because of good thermal conductivity, which often leads to corrosion. The wooden frame requires pre-treatment with an antiseptic and periodic painting. Such recommendations apply to all greenhouses.

Forms and sizes

There are no limits to the variety of shapes and sizes of greenhouses. Nevertheless, for the convenience of work, the recommended minimum dimensions are:

• Height to the eaves - 1.6 m;
• To the ridge - 2,4 m;
• Opening - 1,8 x 0,6 m.

Round and polygonal constructions have more useful area and are not so susceptible to overheating under the scorching sun. The frame can be made of a metal alloy with aluminum, a profile pipe with an anti-corrosion coating, and also an aluminum profile with a polymer coating. Inside the room, the aggressive environment is humidity and high temperature. Therefore, the best option for the frame is the aluminum profile. The sizes and prices depend on the type and purpose of the kit. For example, there is a lightweight design, reinforced, country, under glass, film or honeycomb polycarbonate. The area of individual greenhouses can vary from 12 to 26 m ² .

Covering of greenhouses

The thickness of the coating material is selected according to the structure of the carcass. It depends on the size, the angle of the roof and other parameters. Depending on the complexity of the design, the installation of greenhouses is a rather lengthy process. The material for the covering can be ordinary transparent or tinted glass. Installed double-glazed windows, proper ventilation and heating will allow to grow vegetables in the cold season. Cellular polycarbonate has some advantages over glass. Now it is more often used.

Installation of greenhouses, in addition to the coating, will require the presence of doors, windows and transoms for ventilation, as well as some items for interior decoration - partitions, plant fasteners, boxes, etc. Doors, like windows, can be sliding, swinging, tilting. Possibility of remote control.

Glass Selection

As a coating, there is mainly a sheet glass with a thickness of at least 4 mm. Its strength should be about 7 kg / m ² . The most common sizes of sheets for the construction of small structures - 50x45 cm Glass for greenhouses should not have a marriage - an uneven surface and air bubbles. Normal glass allows up to 90% of light. Excess of ultraviolet rays in summer can lead to burns of plants. You can cover the inner surface of the glass with a varnish. But translucent and tinted glasses reduce the amount of light in a short day. Therefore, it is recommended to shade the greenhouse a little in hot weather.

When choosing the installation site and the angle of the roof , consider changing the position of the sun during the day and season. The roof is closed from the bottom up with an overlap of 6 mm. The glass is strengthened with putty, mastic or a special sealant for heat-saving. Some greenhouses of glass and aluminum have frames without bindings. The coating is inserted into special grooves (poles) and does not require putty.

Advantages and disadvantages

The most weighty argument in favor of glass is its high light transmission capacity. The material is relatively inexpensive and has thermal insulation properties. The service life of the glass is long. Broken patches are easily replaced, while used material can be used. It is easy to wash, with time, the positive qualities are not lost. Buildings with pitched roofs are not afraid of snowdrifts.

Greenhouses of glass and aluminum should be installed on a brick or concrete foundation (monolithic tape or block) at least 80 cm deep. The biggest drawback is the enormous weight of the covering material. Therefore, a strong and high-quality frame is needed. The most reliable is a building with vertical walls and a gable roof. Unreinforced, without a special coating, glass is fragile enough, it can easily break from impact, heavy wind or hail. Considerable erection and proper use of the greenhouse will allow us to grow a good harvest.
