The dream of almost any summer resident is a greenhouse with an opening roof. This design allows you to save cultivated plants even in winter, and in summer provides access to them of solar heat and fresh air. Today, the market has offered a huge number of such products that differ in various design features.
For example, a model called "Country Star" consists of polycarbonate panels that are inserted into grooves and can be removed individually or all together. In summer, the roof of such a greenhouse will provide ventilation, and in winter it will not allow plants to freeze, while maintaining soil fertility.
In general, as practice shows, factory models are more effective in growing cultivated plants, since they are more durable and allow you to save plants until late autumn. In addition, such designs are more practical, because they can be cleaned for the winter (unlike home-made greenhouses, which are exposed to strong winds and snow loads, which leads to their premature damage.
The design of the greenhouse "Country Star" with a removable roof
This greenhouse with a removable roof has sliding windows and doors that can be opened from the outside. Width, height and length are 2.52 x 2.23 x 2.17 m respectively. However, using inserts, the model can be lengthened. The frame is based on a profile whose cross section is 44 x 15 mm, while its thickness is 1 mm. The distance between the arcs is 1 m.
Polycarbonate acts as a coating, and fasteners - an installation kit, which provides for the presence of screws with thermal washers. The frame is made of galvanized iron, which is assembled using nuts and complete screws. Such greenhouse designs have T-shaped legs, which are installed on the foundation or in the ground. Installation on a wooden bar is possible.
The design of the Matryoshka greenhouse with a sliding roof
All sections inside such a structure are lifted and shifted to the ends. If necessary, the summer resident can dismantle the roof at all. For this, the wing nuts are unscrewed, and the section is lifted and mounted on the end. In just 10 minutes, the greenhouse can be turned into a roofless structure.
Such a greenhouse with a sliding roof is very convenient for transportation. In the package, it can fit in a passenger car, because it is a polycarbonate panel, rolled into a meter roll. The panels in the conditions of the plant are cut out according to the valve, this eliminates flowering from evaporation and humidity. Tightness is guaranteed by strips, as well as by a self-adhesive sealant. This greenhouse with a retractable roof is a solid structure made of a closed square galvanized pipe, the cross section of which is 25 mm. The arcs are double. The model is able to endure a load of snow of 85 kg / m 2 . If the panels are removed, the load can be increased to 200 kg / m 2 .
What else you need to know about the design of a sliding greenhouse
Such greenhouse designs are lightweight. After all, polycarbonate panels have a specific gravity of 200 times less compared to glass. They transmit ultraviolet light and saturate plants with life-giving power. The material without loss of technical characteristics can be operated at a temperature range in the range from -40 to +120 ° C. The manufacturer claims that such a greenhouse will be ready to last more than 30 years. Its width is 3 m, while the length may vary depending on the model. This parameter is 3 or 7 m. The price will also depend on the number of sections. For one of the models you will have to pay 22,000 rubles, while for another - 36,000 rubles.
Convertible greenhouse construction with a retractable roof
An opening roof greenhouse is also available for sale in the Cabriolet version. If there are snowfalls, then in just 10 minutes you can move the roof off by removing the clamps and sliding the meter sheet. In the heat, you can provide ventilation in the same way. The facade is all-welded and is made of profile steel pipe of square section with a side of 20 cm. The design has a base and an arch. Height, width and length are 2.2 x 2.8 x 4 m respectively. The last parameter can be chosen by summer residents as desired.
This greenhouse with an opening roof is painted in the area of the profile pipe with white powder paint. The distance between the arches is 1 m, and the design itself has 9 couplers, vents and two doors. The kit comes with pins for installing the frame in the soil. Arches are interconnected according to the principle of pipe to pipe. Parts are joined by argon arc welding.
Making a hinged greenhouse
If you need a window in the roof of the greenhouse, but you could not get the desired model of construction, you can make it yourself. Polycarbonate will be selected as a covering material. The framework uses metal frames. The frame should be made of galvanized profile, vertical racks are installed for this, and their lower ends will have to be welded to a square corner with a side of 40 mm.
At a right angle to the corner, you need to weld a segment for support in order to exclude the deepening of the profile into the soil. Arched triangular roofs are connected by crossbars. Planks are cut at an angle of 45 ° and connected in a frame, they need to be pulled together with self-tapping screws. A seal is installed on the back of the strip.
Work on the frame
The greenhouse skylight never hurts. But if your budget is limited, then this design can be done independently. Speaking of the above, it is worth noting that the next step is to install the framework in the frame. To do this, the upper corners are strengthened for him. The lower part of the frame should be moved into the frame. The frame and frame must be moved in such a way as to ensure reliable grip. If necessary, dismantle the scope of the action must be carried out in the reverse order.
Greenhouse made of wood and film
A greenhouse with a sliding roof can be made of wood and PVC film. As a basis, you can take wooden frames that will make the roof openable and removable. Most often, the film is fixed with a conveyor belt or nailed with ordinary nails. Sometimes slats or glazing beads are used, but in this case the wood may dry out and the film may break. This probability can be eliminated if the film is screwed onto a glazing bead and fixed with a construction stapler.
As an alternative, packaging tape can be used. The material is pressed to the base, and then it is shot with brackets at a distance of 10 cm from each other. If you buy a reinforced film, then you can fix it with the brackets of a furniture stapler, the result will be long. Such a greenhouse with an opening roof should be covered without sagging and excessive tension of the material. Otherwise, the wind will act on the covering material, which will quickly tear it.
Arched greenhouse under the film
A film greenhouse can be made by you on the basis of an arched construction. In this case, it is necessary to equip the foundation. For the frame, you can use 40-cm pipes, at the end of which a tee is welded. This will protect the greenhouse from wind loads. A cross must be welded to the other end by attaching a piece of an 80-centimeter pipe to the side outlet. After that, the whole structure can be welded into a single whole, it must be done in such a way that it forms a single line.
A greenhouse made of plastic windows, made independently, will be very expensive. Therefore, if you decide to acquire such a greenhouse, then it is better to purchase it from the factory by collecting it at your own site. At the next stage, you can install a greenhouse, for this a ditch is prepared, in which the lower horizontal harness is installed. Arches are attached, and then welded, for which they use a vertical piece of pipe. The second end must be attached to the opposite side of the harness. This will get the arch. At this stage, longitudinal elements are installed, which will be 10-meter boards. Wooden parts must be treated with an antiseptic before installation.
To form the ridge of the greenhouse, you need to use help. One master will hold the bar inside the greenhouse, while the other at this time will screw it outside through the pipe using self-tapping screws. Now you can install doors and vents made of square bars with a side of 50 mm. The lower beam of the end strapping is treated with an antiseptic, because it will be in contact with the soil. Next, the greenhouse can be covered with a film and fill its end with earth. Material must be protected where it will come into contact with the metal frame. On hot days, the steel heats up to +70 ° C.
Conclusion
If you decide to use wooden frames for the manufacture of the greenhouse, then initially you must install the foundation, which can be equipped with red brick. In order to exclude the contact of wood and stones, it is necessary to lay a roofing material between the layers, burying its edge inside the greenhouse.
