Greenhouse glass - for those who appreciate quality

Glass greenhouses – a time-tested, safe and aesthetically attractive version of truck crops create ideal conditions for growth and development. The cost of construction and installation depends on the materials used, size and whether the parcel owner to buy a greenhouse or to produce it myself.

Historical data on the greenhouse

History of vegetable growing with use of artificial methods of farming dates back to very remote times. Roman gardeners were carrying out landing on the sun during the day and removed at night in a warm room, and constructed a kind of greenhouse, covering the beds with a layer of manure, which was kept warm.

Over time, those ancient Romans invented to protect the landing rails, covered with thin plates of mica, allowing light to enter. These facilities can be considered the prototype of modern greenhouses.

The First greenhouse made of glass appeared in Europe in the mid 16th century. They are mainly used for cultivation of flowers and exotic plants. Glass was very expensive, so that ordinary people could not afford such a luxury for growing vegetables.

The Invention is a method of creating flat glass in the 17th century in Germany led to the construction of greenhouses. However, the privilege of having a greenhouse made of glass possessed of wealthy citizens. Only in the early 20th century, when the mass sheets glass and the price has fallen sharply, the ability to build glass greenhouses have appeared at all.

In Russia, glass greenhouses appeared in Peter 1 and was also rare, as their construction cost is too expensive. In the 30-ies of the last century began the mass construction of greenhouses on a national scale. Soviet greenhouses supplying fresh products all over the country.

- the glass Surface is not subject to aging and abrasion, therefore, for a long time retains an attractive appearance.

- glass Structure does not change under the influence of high and low temperatures. The shape and size remain unchanged, eliminating the structure from deformation.

- does Not require complex care. Below the glass was clean enough to wash it with water and wipe with a dry cloth.

- resistant to atmospheric precipitation and does not bend under the weight of snow.

- the Broken element is easy to replace.

The disadvantages of glass include the heavy weight, brittleness, high thermal conductivity, a high price compared to other materials used for covering greenhouses.

For glass greenhouses is generally used aluminum or wood, to reduce the total weight of the structure, since the glass itself is quite heavy.

For the same reason, to install the greenhouse glass needs a solid, reliable Foundation. For greenhouses typically use monolithic strip or block concrete Foundation. To lay it should be on the depth of soil freezing, but at least 80 cm.

Usually the glass of a greenhouse do a double-pitched or lean-to sloping roof. Here the choice can be done by the gardener. Below the glass roof of the greenhouses were long, for it was made use of glass thickness of 4-6 mm. thicker may crack as the temperature difference inside and outside can be very large.
