Now polycarbonate greenhouses enjoy the increasing popularity. They have the increased utilization properties in relation to greenhouses from polyethylene and cost not much in view of mass character of production. It is possible to collect the greenhouse independently, though it is necessary to spend time for getting the hang to work with material.
– transparent strong swore at greenhouses from polycarbonate which reminds glass, were fallen in love to gardeners. Today they more often can be met on seasonal dachas and even on industrial facilities, designs from polycarbonate have practically no restrictions in sizes: it is enough to build steady framework also it is possible to build the real greenhouse. Treat the main advantages of such greenhouses:
- frost resistance; - durability;
- continuous solarization; - ease when mounting.
Mounting of the greenhouse demands special conditions. It is important to choose correctly the site for installation of framework. It has to be not darkened site of your kitchen garden with plain and dense surface. Pay attention to wind rose: it is unreasonable to put design on the blown place, the carbonate easily is deformed and torn, and racks can be pulled out by the first wind gust at all.
Greenhouses are divided into two types: - all-metal, - folding. Each of these classes has types of mounting: on the base or on soil basis.
Installation on the base
If you build the base, it will involve additional costs, but greenhouse life cycle will last. The base is done, as a rule, tape type or of blocks which establish on depth not less than 50-80 cm. In case the greenhouse assumes laying of heating and possibility of its operation and in the winter, depth of the base has to be not less than frost depth of soil. The base flooded on greenhouse perimeter is maintained by 2-3 days then start actually mounting which is intuitive.
Mounting
At first the basis is mounted. Collecting needs to be begun from corner, moving to the center of the greenhouse. It is convenient to work from two parties at once, joining the basis on the middle. Each flight has to be recorded on the basis by anchor. Docking units are closed by pads which go in set. In order to avoid darkening of sheets of polycarbonate, edges close up waterproofing tape or normal transparent adhesive tape. It becomes in order that moisture did not get to layers and dust did not jam. Such isolation needs to be done for all mounted sheets. In the established basis arches which are integral and folding fix. Folding it is desirable to collect separately and only then to establish. Such mounting is physically difficult, it is necessary to rise by step-ladder, but it is carried out quicker and more precisely, you do not need to adjust arch on height. After you have mounted sidewalls and the main framework of the greenhouse, it is possible to start greenhouse covering sheets of polycarbonate. Self-tapping screws and insulating washers are for this purpose used. In type of the fact that in the summer when heating the sheets of polycarbonate will extend it is necessary to drill openings slightly more than diameter of self-tapping screws. Completion phase of assembly of the greenhouse is installation of doors. The framework of door and cloth gather separately from the greenhouse and ready are hung on loops. Usually the cloth of polycarbonate should be cut independently under door, it is the most convenient to use construction knife. At first put marking with simple slate pencil, try on collected door, recede at least 2 mm and cut aperture. Stick sheets with adhesive tape then attach loops. Practice shows that in use door openings strongly suffer from mechanical influence therefore scraps of polycarbonate can be used for its strengthening. Just paste them on door perimeter resin bezatsetonovy adhesive or attach on self-tapping screws. It is better for Toeplitz to mount in the spring or in the fall that there were no considerable daily temperature drops. If you want to establish the greenhouse without the base, it will reduce your expenses, but, despite anticorrosive processing of the greenhouse, the term of its further operation because of corrosion of the lower basis can be reduced. When choosing the greenhouse pay attention to that polycarbonate was not less than 4-5 mm thick, and metal base not less than 1.5-2 mm thick. It is necessary in order that the design without problems has transferred winter snowfalls.
