Want to grow thermal-loving plants, and at the same time get a cozy holiday destination? Then the greenhouse of the veranda type is what you need. Choose the necessary materials and structures.
For the gardener and the garden of the greenhouse-veranda is much more convenient located on the removal of the greenhouse. An extension is located with the southern or south-eastern side of the house building. Ideally, it is equipped here by the second way out of the house, leading through the greenhouse on the internal territory of the site. Often the room is equipped with garden furniture and turn into a veranda, but in this case you should take care of efficient ventilation and shading. If you carefully consider the architectural solution, then the glaler extension will not only spoil the appearance of the building, but also decorate it.
Outdoor steel or aluminum rafters make it possible to install sliding sunscreen marquis
1 Cooking sketches
Start work stands with the preparation of the project, which should include sketches of facades, room plan and design part with drawings of parts and nodes.It can not be missed (or heated only in frost with portable devices), and during the construction of walls and roofs - to navigate the moderate heat resistance of about 0.35 m² • ° C / W, which will make it much reduced the cost of materials and works.
2 Select the framework
The optimal version of the foundation for light extension is a pile-screw with a metal or wooden strapping. The walls and roof of the greenhouse are a frame with translucent filling. With their construction, you can use different combinations of materials, as well as ready-made window structures.
Frame an extension collected from painted steel profiles
or glue bars. Aluminum design costs somewhat more expensive
Wooden frame
Wooden frame will cost the cheapest. Accessories are ordered in the joinery workshop or manufactured on the construction site; In the second case, the builders will need a powerful milling mill, a good ribbon grinder and, of course, carpentry skills. The material for strapping, racks and jumpers should serve a glue bar of a pine or larch with a cross section of at least 50 × 70 mm (the greater the cross section, the thoroughly the extension looks like). The rafter design is calculated based on the mass of translucent filling and snow loads. To mount the deaf glazing in the bars choose a quarter from the inner or outdoor side. Square sections can serve as a sprawle. When assembling the frame, the drifts, straight spikes and other types of joinery connections are used. Details antiseptic and color to assembly.
Reiki Reiki (including invoices) not only decorate glass canvas, but also increase their resistance to shock loads
The estimated price of a wooden enclosing structure (taking into account the glass accessories) - 4200 rubles. for 1 m2. If you order a set of details in the workshop, the compounds will turn out to be more accurate, and the quality of the finishes is higher, but the cost of the greenhouse will increase at least one and a half times.
Steel and plastic
Some window and specialized companies ("Plastok", "Window Factory", "Window Center", etc.) also offer greenhouses with a metal frame (from pipes of a square section, channels and brass), in the cells of which are installed deaf and opening sash from PVC . This is a durable and warm design, its average price - 7 thousand rubles. for 1 m2.
Aluminum frame
It is collected from the hollow aluminum profiles for the facade glazing of the production of "Alutech", Aluk, Reynaers, Schüco, etc. They are equipped with seals and are completed with clamping straps for fixing brakes. Usually, T-shaped profiles with a cross section of 40 × 60 mm and more are used for racks. Straps, angular racks, jumpers are performed from pipes. In general, the nomenclature of aluminum products allows you to solve any design tasks.
The main minus of aluminum is high thermal conductivity: if you plan to sculpt the greenhouse in the winter, it is worth exploring the condensate from the parts from the framework details, and in a strong frost they will cover the layer of Inea. It is possible to solve the problem with the help of warm profiles of the composite design (with a plastic thermal survey), but they will cost 2.5-3 times more expensive.
Aluminum frame is difficult to collect on its own - so, without special equipment and templates, it will not be possible to accurately cut profiles and drill holes for installing mortgages or overhead connectors. It is easier to order a set in a specialized company (Volizar, "Alyispece", "Glass Project" and others). At the same time, it is necessary to focus on the cost of 7500-9500 rubles. For 1 m2 fences.
Special combined systems (steel + PVC) include decorative elements laminated under the tree
When buying a greenhouse team, do not forget to turn on the package of drainage. It is desirable that they were painted in the same color as the part of the frame
3 Choose glazing
For vertical glazing, the greenhouses are optimally suitable for single-chamber windows with a thickness of 16-24 mm. They have sufficient heat transfer resistance (0.36-0.38 m² • ° C / W), high light transformation, resistance to scratch and ultraviolet. Enhance the safety of glazing, and at the same time decorate an extension will help frequent bindings. Single silicate glasses, even increased thickness, use it is undesirable - they are almost not protected from cold and fogged from the inside even at the positive temperature on the street. Monolithic polycarbonate, including quite thick (8-10 mm), will also not support the positive temperature in winter in the greenhouse. Well, a cellular polycarbonate for the walls-veranda walls is not used because it is not clear enough.
For the roof there are increased safety requirements. It cannot be assumed that when the glass is destroyed as a result of a random strike or uneven heating (thermoshock), large fragments sprinkled on top.
Therefore, a durable monolithic polycarbonate is used with a thickness of 10-12 mm or double-glazed glass with tempered glass (outer) and triplex (internal). In addition, you can use a cellular polycarbonate with a thickness of 16 mm. It has less light transformation, but it is much better isolates warmth and is relatively inexpensive (from 650 rubles per 1 m2).
Cellular polycarbonate is not as the windows, but superimpose on the rafter, fixing screws with clamping washers and closing the joints with overlays. The coefficient of thermal expansion of the material is several orders of magnitude higher than that of the glass, so it is necessary to arrange compensation gaps.
The design of translucent facades and roofs should be designed taking into account the wind and snow loads
In warm sunny weather, the greenhouse is very hot, and it is necessary to ventive well. To do this, along with a deaf glazing, windows with opening flaps are inserted into the gaps between the frame racks - swivels (swinging) or swivel (second slightly more expensive, but much more convenient). It is believed that the area of windows should be at least 20% of the greenhouse fencing area, but much depends on the nature of the area (open elevation or wooded lowland), the presence of shading and other factors. Maximum efficient ventilation provides a combination of windows and roofing hatches. The latter stand from 11 thousand rubles. For 1 m2) and ideally must be completed with the electric drive with the remote control (about 6500 rubles), although you can do without automation and use a special sixth.
4 Do not forget about the door
In the greenhouse are most appropriately glazed inlet doors from wood, PVC or aluminum. The cheapest (from 9 thousand rubles) will cost a swing wooden door, which is also reliable than folding and parallel-sliding models. The door leaf should be equipped with two double-glazed windows - its strapping must be strengthened with an average horizontal jumper. When buying, pay attention to the reliability of the fittings and the height of the threshold (most convenient thresholds of the minimum height of the rounded aluminum profile).
The electric drive can be built into the window frame
Constructions from cold aluminum profiles are durable and durable, they are ideally suitable for the unheated greenhouse
