Do you want to see fresh and tasty vegetables on the table? Then it makes sense to take care of greenhouse construction. The glazed design made with own hands quite will be suitable for the seasonal dacha. Such greenhouse will provide the good growth and ripening of fruits, it is durable and reliable. At the correct leaving the glass greenhouse is capable to serve not one year.
Advantages and shortcomings of the glass greenhouse
The construction of this type is carried to long-term. Glass walls and roof do not detain the ultraviolet necessary for maturing of vegetables. When using of the tempered or laminated glass the greenhouse will not be threatened by neither strong heat, nor hail, nor frosts. In the greenhouse from plant glass are ill less and better fructify. For this reason the glass greenhouses can be seen often at dachas and garden sites.
The glass greenhouse has good thermal insulation. In need of it it is quite possible to install heating devices.
Such design has also shortcomings. Glass differs in fragility and demands the careful address. It is very heavy material. Its use demands installation of the strong base and reliable framework.
Where to locate the glass greenhouse
When choosing the place for installation of the greenhouse it is necessary to consider degree of illumination of the expected site. Nearby there should not be trees with branchy krone and other objects capable to give shadow.
It is recommended to orient the greenhouse in the southern direction. It will allow to receive uniform illumination and receipt of heat during all daylight hours.
It is necessary to take into account and the wind mode of the territory. The place has to be not blown. From the possible attack of wind it is desirable to arrange protecting strip from bush. But it is sometimes rather simple to warm this side of the greenhouse suitable materials.
It is the best of all to choose under the glass greenhouse the flat and dry place. The small hillock will be ideal.
Structure of the glass greenhouse
Use of glass narrows the choice of architectural form. Glass does not bend therefore the rectangular or many-sided construction will be the best form. The roof will approach one - or twin. But construction of pavilion roof with four edges is quite possible. The wall greenhouse will help to save the place on the site. It will demand also much less expenses on heating.
For construction of framework it is the best of all to use wooden bar with a section of 50х50 mm. It is very convenient to use old window frames for construction of walls and roof. The greenhouses made of modern double-glazed windows or glass blocks meet. Such design demands strengthening of upper part and arched roof. Consider that the maximum permissible inclination of roof at the glass greenhouse makes 15 degrees.
Before works will not be superfluous to make the detailed plan of construction on paper and to execute the sketch. It will allow to define consumption of material and will save your time.
Construction of the base of the greenhouse
On the chosen and cleared away place execute division of land by means of pegs and cord. Establish continuous footing on contour of future greenhouse. Correctly filled in basis is capable to keep in addition to 10% of heat. Solution is recommended to be filled in on soil frost depth (normally it is 50-80 cm).
The technology of laying of the foundation does not differ in complexity. The trench up to 30 cm wide is dug out. In trench sand is filled up and carefully stamped. Then armature keeps within. After that in trench fill in concrete. Over concrete do brick binding.
Framework construction
The strong framework can be made of wood, plastic or of metal section. The tree is more eco-friendly, and metal differs in durability. Wooden parts of design need to be impregnated with protective antiseptic structure, to cover with mordant and to paint finally.
If for production of the greenhouse it is supposed to use frames from windows, the framework for them is prepared from bar with a section of 100х100 mm.
Pay special attention to connection in whole of elements of framework, frames, corner posts and basic bars. Vertical bars fix to horizontal nails or long self-tapping screws. At the last stage on the greenhouse fix farms, and over them put ridge board or corner.
Glazing of the greenhouse
For cutting of glass use plain surface and the glass-cutter of high quality. It is desirable to have glass reserve: it can be necessary in case of defects in work. Cutting out glass, surely protect hands gloves. The glass elements which are cut by the size it is recommended to fix to framework carnations and silicone sealant. From outer end glass is framed with fillet from wood or rubber. The roof should be glazed from its lower part to top, laying putty layer. After clearing of rubble and debris and operational development of small parts the glass greenhouse is prepared for use.
