Greenhouse with double-glazed windows is relevant not only in regions with cold weather, but also in other suburban zones such as prolonging the time of fruit-bearing of submerged crops or yearlong usage.
The advantages of these glazing are undoubted:
In addition, manufacturers offer you double-glazed windows with a set of necessary functions, such as special coatings for heating and energy savingprotection against mechanical impacts and reduced temperatures, as well as soundproofing.
System of auto-ventilation of all greenhouses.
Of course, the glass greenhouse also has disadvantages, which ought to be taken into consideration when constructing it. By way of instance, the simple fact that glass is quite heavy material (1 m² of glass 4 mm thick weighs 10 kg, and 6 mm – 15 kg), has to influence the presence of a solid base, in addition to the building of a strong structure – framework.
On a bright day, the transparent coating of greenhouses allows short-wave solar radiation. It is absorbed by dark surfaces (ground, equipment, plants), turns into long-wave radiation and stays in the construction. This transformation happens with the release of warmth, which makes a greenhouse effect inside the greenhouse.
So, glass windows absolutely allow the sun’s beams in the area and almost completely keep the rear radiation, not allowing it to venture out. To put it differently, unlike film, glass has become the most heat-saving material, and this is one of the main features of a great greenhouse.
