If you are an avid summer resident, then you probably wondered how the year-round greenhouse is built.
General arrangement of a year-round greenhouse
When the year-round greenhouse with heating will be built, you can take for the main dimensions presented in the article. However, the dimensions of the building will depend on their own preferences, the amount of seedlings grown, as well as free space on the site. In the example, we will consider a greenhouse whose width is 3450 millimeters, while the length will be 4050 millimeters. In the end, you will be able to get a total area of racks of 10 square meters, on which it will be possible to grow seedlings. If planting in pots whose diameter is 100 millimeters, then from the mentioned area it will be possible to have 1000 units of seedlings. A year-round greenhouse of this type will consist of a buried room, inside which racks are installed. The roof must be made transparent, while double-layer polycarbonate is recommended as a covering material. As mentioned above, the construction should not be buried if the site has high groundwater, but in this case it will be necessary to sprinkle with soil on the outside of the wall. The length can be increased if necessary, for this you can add sections. The ridge beam should be lengthened by extension. The connection is carried out in half the tree with a beam, which has a similar section.
Dimensions and supports
If you build a year-round greenhouse, then at the junction of the beam you will need to install a support, the last of which should look like a triangle. Skate support is necessary to maintain the beam. Please note that the support must not come into contact with the polycarbonate coating. The supporting part has the strength properties, but does not impede movement inside the greenhouse. This addition is only required when the length of the greenhouse is more than 4000 millimeters. If the structure will have a more impressive length, then the supports should be installed every 4 meters. As for the corner elements, they must be made of square beam, the side of which is 100 millimeters.
Wall construction and greenhouse insulation
If you will be building a year-round greenhouse, then on both sides of the support it will be necessary to sheathe it using a grooved board, and the resulting space should be filled with a heat insulator. In order to make the design cheaper, it is recommended to use a round timber, its diameter can vary from 120 to 150 millimeters. For wall cladding, a croaker is often used. The space inside the walls is insulated, for this you can use sawdust, expanded clay or slag. If the first option is applied, then quicklime must be added to the main ingredients . This way you can scare away rodents. Shelving should be installed along the side walls, 600 millimeters should be retreated from the floor surface. In their manufacture should use boards.
Excavation and installation of supports
If you decide to build year-round greenhouses with your own hands, then first you need to dig a pit, the depth of which is 600 millimeters. Width and length may be greater than the greenhouse itself. At the bottom, markings should be made on which the installation of supports will be made. As soon as you decide on the layout, you will need to dig up the supports, while you need to go deeper by 500 millimeters. At a height of 1020 millimeters from the surface of the earth you need to pull the twine, which is leveled with the help of a level. She will help to establish correctly all support. Next is backfill. To do this, apply the earth, which is carefully tamped after laying.
Installation and wall covering
Year-round greenhouses with their own hands are built according to a certain technology. It involves leveling and further cladding the walls. Last manipulations must begin from below. This must be done simultaneously from the inside and outside. As soon as you complete these work, you need to cut off the ends of the boards that go beyond the supports. At the corners of the greenhouse from the inside, on the boards you need to nail the bars, which have a square section with a side of 50 millimeters. They must be installed vertically. They will be fixed to the skin of the rear and front walls.
Insulation
Year-round industrial greenhouses, like ordinary ones, suggest the presence of an insulating layer. It must be sealed if necessary. The material is poured so that it exits to the top of the wall. After these works are completed, the open top must be sewn up with boards, their width should correspond to the thickness of the walls. The inner part is covered with insulation, which has a reflective surface. Foamed polyethylene is well suited for this .
Roof device
Greenhouses for year-round cultivation, as a rule, have a roof made on the basis of a frame. The rafters should be connected in half the tree, the jumper is beaten so that the distance in the lower part is equal to 3450 millimeters.
The jumper is considered a temporary part, so it must be installed in such a way that it can be removed afterwards. Do not forget that you do not need to hammer nails to the very end, you must leave a gap of 7 millimeters. This will make it easier to remove jumpers.
Final work
Greenhouses year-round use suggest the presence of a rafter system, which is nailed to the support. After that, the jumpers can be removed. Under the rafters, a ridge beam should be mounted. Now under it are the front supports. Their size is 880 millimeters. Greenhouses for year-round use with heating suggest at the last stage the installation of a furnace, which is preferable to be placed in the vestibule.
