It is known that the rate of photosynthesis, i.e., the decomposition of carbon dioxide by a green leaf, depends significantly on the wavelength of light falling on it. The highest rates are achieved when green leaves are irradiated with orange-red light.

In addition, if a small amount of light of a certain wavelength is "mixed" with the main light on which the plant is grown, then the degree of utilization of the entire light flux increases, which manifests itself in the enhancement of all vital processes of the plant, including an increase in the rate of photosynthesis. This phenomenon is called the "amplification effect" or "Emerson effect".

Numerous studies have shown that it is not the quantity of light, but its quality (wavelength) that accelerates photochemical reactions.

These facts could not fail to attract attention, and experiments on using the "Emerson effect" to increase crop yields were carried out in many countries. The result of such studies was the creation of special light-converting materials of the "Polisvetan" type, the use of which in the practice of growing vegetables, berries, flowers, woody crops, for forcing seedlings, etc. in greenhouse conditions increases economic productivity by 20-60% compared to plants grown in structures covered with materials that do not have a light-converting effect.

This effect is achieved by the introduction of special additives into the polyethylene film, which allow converting the part of the ultraviolet radiation of the solar spectrum that is useless for plants into the radiation of red light necessary for their life.

Among the most famous Russian developments are brands such as "Redlight", "Harvest", "Polisvetan" and "Anti-mold"

These films are a new generation of polyethylene films with unique Light-converting properties, which received the highest award at the International Exhibition "Eureka-96" in Brussels. The effectiveness of polysvetane films is confirmed by tests of the following institutions:

  • State Agrarian University of the Russian Federation
  • The Russian Academy of Sciences
  • Central Scientific Research Institute
  • Ministry of Agroindustrial Complex of Ukraine
  • Ministry of Agriculture and Food of the Russian Federation

What else should you pay attention to when choosing a film?

Film thickness.

Inexperienced summer residents think that the thicker the film, the longer it will last. Nothing like this. Ordinary polyethylene with a thickness and even 200 microns will crack and tear within 4 - 5 months if it is not stabilized. It is the presence of light-stabilizing elements for a greenhouse film that is most important. As you know, ultraviolet light quickly destroys the film, as a result, it simply disintegrates into small pieces. This process is inevitable, but it can be significantly slowed down. This is what light stabilizers do. By the way, for stationary greenhouses, an elastic film with a thickness of 120-150 microns is optimal, for greenhouses on arches, you can also use 80-100 microns.

A separate note about reinforced film. This film is good for everyone - it is really strong and reliable, but ... it is completely unsuitable for the greenhouse industry. Due to its relief, it gathers dust much faster, becomes cloudy and, ultimately, practically ceases to transmit light.

And yet - regardless of the appearance of the film, experts recommend changing it in the greenhouse at least once every three years, since the film becomes cloudy over time and its light transmission deteriorates, which negatively affects the yield and quality of agricultural crops. If it is well preserved, then it is better to use it for other household needs.

Film color

Films are tinted with food coloring only to distinguish them when sold. Color does not carry any other functional load. The dye then simply fades out in the sun, and the film becomes transparent. And persistent coloring, on the contrary, worsens the quality of the film, which would allow less color to pass through. In general, for greenhouses, the most ideal option is a glass or polycarbonate coating (flexible, transparent plastic). But the film is much cheaper, which, among other things, reduces the likelihood that your greenhouse will simply be "undressed" ...

Beware of counterfeits.

No one can determine by eye whether a product is light-stabilized or not, and the only guarantee in such a situation can be knowledge of trusted stores where you have never been deceived, or buying material directly from the manufacturer.

One of the oldest manufacturers of light stabilized films brands "Redlight", "Anti-mold", "Harvest" and "Polisvetan" in St. Petersburg is a production and commercial company "OPA", which has been working in the polyethylene packaging market for over 15 years and is a member of the St. Petersburg Chamber of Commerce and Industry.

For 7 years the company "ORA" has been a permanent participant of the World Fair "Russian Farmer", where it was repeatedly awarded with diplomas of the Fair, incl. in 2001 she was awarded a diploma "For the development of new technologies."

Advantages of a metal picket fence:

1. Easy to maintain: no need to paint like a wooden fence

2. Safety rolled edges cannot be cut, the picket fence meets all quality standards.

3. Ease of transportation and installation (it is very compact and has a low weight, which allows it to be transported in a car, and only self-tapping screws are needed for installation.

4. Durability - metal tolerates atmospheric temperature changes better. A metal picket fence is not afraid of moisture like a wooden picket fence. The metal cannot rot or deform from moisture, and it is protected from corrosion by a zinc layer and a polymer coating.

5. Excellent combination with stone and concrete, can be combined with wood, and decoration with forged elements makes the fence individual and unique.

6. Good maintainability. If you suddenly have damage for any reason, there is no need to replace the entire perimeter, it is enough to replace only the damaged part.

7. The ability to adjust the light transmission of the fence.

Metal picket fence "Constanta" Execution: gloss, matt Coating: one-sided, two-sided Warranty 10-25 years. The picket fence is used as a fence for private houses, cottages, summer cottages, suburban areas, when filling gates and gates. For the manufacture of a metal picket fence, rolled sheet steel with anti-corrosion and polymer coating is used. The advantages of a metal fence: it is durable, environmentally friendly, has a wide palette of RAL colors, is easy to install and has an excellent appearance. You can use various options for decorating the fence: one-sided or two-sided filling (checkerboard pattern). The distance between the picket fences determines the degree of privacy of the territory: a step of 2-4 cm for one-sided filling, a step of 6-8 cm for two-sided filling. Usually 1 lm. the fence accommodates 6 vertical pickets with one-sided filling and 9-11 with two-sided "checkerboard" filling. The "default" top cut is rounded; on request, a straight cut is made (for example, to be inserted into the frame of a gate, wicket or frame section).

Paroc has been used successfully to reduce heat transfer between the warm and cold sides of a building. Thermal insulation properties are due to the low thermal conductivity of stationary air and the special structure of the material: stone wool consists of the finest fibers chaotically interconnected and forming cells filled with air. This leads to a low density of the thermal insulation material (at least 30 kg / m3) and a high air content in it (more than 90% by volume). This structure provides low thermal conductivity of stone wool products. Thanks to this structure, it can also be used for soundproofing rooms.

Fireproof properties
The raw material for the production of Park stone wool is basalt rock. Based on tests carried out in Russia, Belarus and Ukraine, as well as in Europe, according to various methods and standards (ISO 1182, DIN 4102, GOST 3024494), Paroc stone wool products are classified as non-combustible. Basalt wool materials effectively prevent the spread of flame and can be used as fire insulation and fire protection. Therefore, these thermal insulation products meet the most stringent fire safety requirements.

Hydrophobic properties
Rock wool fiber is inherently water-repellent. In addition, in the production of stone wool products, special additives are used to enhance their water-repellent properties. Even if in some case water penetrates into the fiber (for example, under pressure), then after the cessation of such exposure, the moisture from it will evaporate. Compared to many other building materials, Paroc has a high vapor permeability. With good water vapor permeability, Paroc stone wool almost always stays dry, maintaining the internal temperature regime of the room.

Durability and easy installation
The thickness and width of Paroc soft insulation products are selected based on the most common frame structures. This greatly facilitates installation and allows you to achieve tight contact between the insulation and the frame elements. The elasticity and lightness of thermal insulation materials makes their installation simple and convenient. At the same time, the products do not shrink and are not subject to temperature effects. Stone wool has a high chemical resistance. Paroc is non-corrosive on mating surfaces. This is especially important in the insulation of pipelines and tanks, in systems of hinged ventilated facades and in lightweight frame-type structures.

Safety and environmental friendliness
Paroc products are completely safe for the environment and human health. It is non-toxic, non-biodegradable, odorless and dust-free.

Lightweight slabs of mineral stone wool based on basalt fiber. PAROC eXtra insulation is used for thermal insulation of frame structures and other units where the material does not experience external loads:
-exterior walls,
- pitched roofs,
- intermediate floors,
- attics,
-floors,
-inner partitions.

Polycarbonate for greenhouses is a modern material that perfectly replaces glass, while being in no way inferior to it in many properties, and even superior in some. Polycarbonate is a polymer that, due to its characteristics, is defined as a synthetic, low-combustible material. If we compare this material with acrylic and glass, it turns out that polycarbonate is much more durable (100 times more than glass and 10 times more than acrylic). The temperature range of application is also wide, in which the properties of the material remain unchanged - from -40 ° C to + 120 ° C.

Polycarbonate withstands hail and at the same time does not crack and, moreover, does not break like glass.

It is used for masonry and simultaneous cladding of external and internal walls of buildings and structures.

Putty putty Acryl-Putz is intended for indoor use. It is especially recommended for use on gypsum plasterboard (GKL), for filling technological joints with the use of reinforcing tape (serpyanka). Also well suited for filling and leveling irregularities on all mineral substrates (plaster, brick, concrete), wooden substrates.

Due to its formulation, the Acryl-Putts start-finish putty mixture can be used as a finishing layer without the use of ready-made putties.

The Acryl-Putzne putty has shrinkage properties, dries up within a short period of time, is easy to sand and does not crack when applied in a thick layer (up to 3 cm).

Method of application of Acryl-Putz ST-15 start-finish putty:

Dry Acryl-Putz putty should be diluted with clean, cold water in the proportion of 0.3 liters of water per 1 kg. dry mix. Do not use metal, rusty dishes as a container for preparing the mixture. A plastic bucket or bowl is best. Mixing is carried out using a special paint mixer, until a homogeneous mass is obtained, without lumps. It is recommended to mix the mixture in two passes, with a technological pause (3-5 minutes).

Puttying work should be carried out at an ambient and base temperature not lower than +10 gr. Do not apply a layer thicker than 3 cm in one go. The recommended layer thickness is 3 mm. The dried surface is rubbed with sandpaper or a special grout mesh to obtain a perfect surface. Further, the surface is primed and painted with any emulsion paint.

Plumbing shutters - why they are:

Vinyl or textile bathroom curtains can hide unsightly pipes and sanitary ware, but they have undeniable drawbacks. They will not look very aesthetically pleasing, often they will not be able to completely hide the whole view and will not provide any protection against the penetration of children. Blinds are a very cheap option, but in the full picture of the bathroom they look like a relic of the Soviet past and do not complement the design with their presence.

Partition from chipboard. This option is harder and more practical for hiding the sanitary ware in the bathroom. However, this will not add practicality in achieving the main goal - hiding all plumbing units with the greatest efficiency. Among the disadvantages of such a solution will be fragility. Chipboard is not suitable for a damp room: it will swell very soon, when opened and shifted to the side, it will cling to the guide profiles, and after a while it will become unusable.

Plastic screens can be considered a very simple, durable way to install them in the bathroom. Such a screen fulfills its functions very effectively, both aesthetic and practical. However, in various force majeure situations, it is sometimes not very convenient to get access to communications, so this screen has both positive and negative sides.

Blinds in the bathroom are more of a fashion influence than a necessity. They are very practical in terms of design. However, it should be noted that noise and thermal insulation are minimized. In addition, the blinds allow you to close only part of the communications, and the rest will have to be closed "tightly", so it will be very difficult to get access to them in the future. Therefore, blinds are not the best solution for large families.

Let's talk a little about plumbing shutters. They are a great alternative for the same purposes as the previous overlap options:

The roller shutter curtain consists of lamellas (horizontal profiles, fastened together by hooks). This profile can be made of aluminum or steel. Moreover, the lamella cavities are filled with polyurethane foam. It is worth noting that plumbing shutters are made according to the same principles as ordinary outdoor shutters, so they have the same long service life. And they will cope with the climate of the bathroom without any problems. If used correctly, aluminum roller shutters will serve you for about 10 years.

Their scheme of work is also quite simple. The lamellas, fastened together, when opening the roller shutter, are wound on the shaft inside the box. The spring with which the shaft is connected compensates for the weight of the curtain and does not allow it to close spontaneously, this will also allow the roller shutters to be opened only to a certain level, without the need to fix them.

Positive aspects of plumbing roller shutters.

Among the positive aspects of using roller shutters in the bathroom, one can single out excellent sound insulation of pipes. We have already written about sound insulation in the bathroom. And this moment, when using roller shutters, can serve as an additional item in the list of their positive aspects.

The next positive point will be access to all emergency places of the water supply system in the event of any leaks. The fact is that roller shutters can cover the entire space from ceiling to floor, so using it as a "back wall" will allow you to literally get instant access to the place where plumbing intervention is needed.

No less important, the positive side can be considered isolation from the penetration of children. Roller shutters will always protect pipes, meters and valves from children's games and pranks. Moreover, they can be closed in the same way as street shutters: with an external lock. And you can be sure that no one gets to the pipes without your permission.


What is the greenhouse effect?

Short answer:

The greenhouse effect is a process that occurs when gases in the Earth's atmosphere trap the heat of the Sun. This process makes the Earth much warmer than it would be without the atmosphere. The greenhouse effect is one of the things that make the Earth a comfortable place to live.

Watch this video to learn about the greenhouse effect!

How does the greenhouse effect work?

As the name suggests, the greenhouse effect works ... like a greenhouse! A greenhouse is a building with glass walls and a glass roof that is used to grow plants such as tomatoes and tropical flowers.

It stays warm inside the greenhouse even in winter. During the day, sunlight enters the greenhouse, which warms the plants and the air inside. It is colder outside at night, but it remains quite warm inside the greenhouse. This is because the glass walls of the greenhouse trap the sun's heat.

The greenhouse captures the heat of the sun during the day. Its glass walls trap the heat of the sun, keeping the greenhouse plants warm - even on cold nights.Credit: NASA / JPL-Caltech

The greenhouse effect works in much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat like the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases.

During the day, the sun shines through the atmosphere. The surface of the earth is heated by the sun. At night, the Earth's surface cools, returning heat to the air. But some of the heat is trapped by greenhouse gases in the atmosphere, which is what keeps our Earth warm and cozy at an average of 14 degrees Celsius.

Earth's atmosphere traps some of the sun's heat, preventing it from escaping back into space at night. Credit: NASA / JPL-Caltech

How do humans affect the greenhouse effect?

Human activities are changing the natural greenhouse effect of the Earth. When fossil fuels like coal and oil are burned, more carbon dioxide is released into our atmosphere.

NASA has observed an increase in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth's atmosphere to trap more and more heat. This causes the Earth to heat up.

What reduces the greenhouse effect on Earth?

Like the glass greenhouse, the terrestrial greenhouse is full of plants! Plants can help balance the greenhouse effect on Earth. All plants - from giant trees to tiny phytoplankton in the ocean - absorb carbon dioxide and release oxygen.

The ocean also absorbs a lot of excess carbon dioxide from the air. Unfortunately, the increase in carbon dioxide in the ocean changes the water, making it more acidic. This is called ocean acidification.

More acidic water can be harmful to many marine life, such as some shellfish and corals. Warming oceans due to too many greenhouse gases in the atmosphere can also be harmful to these organisms. Warmer water is the main cause of coral bleaching.

Today, purchasing a greenhouse will not be difficult: the variety of options on the market is simply amazing - rectangular, square and even pyramid greenhouses made of polycarbonate, metal and wood. The ideal greenhouse: what is it? But which one is right for you and how to choose the perfect greenhouse? This is what we'll talk about. Ideally, a greenhouse for a summer residence should be reliable, of high quality, as durable as possible and adapted to the weather conditions of your region. It is also desirable that it be practical, easy to use and, of course, inexpensive. Choosing a greenhouse, each of us is guided by different motives. So, one is quite enough of the pretty appearance of the greenhouse, which will look great against the background of a private house or a summer cottage. Photo from the site www.mpal.ru Others - those who consider the greenhouse as a business or help in the household - put forward more serious requirements for the characteristics for them, its appearance also plays an important role, but not the most important. Before choosing a greenhouse, you need to decide: why do you need it? It's one thing if you are going to use it to provide the food needs of your own family, and quite another if it will serve to generate additional income, and over time your hobby will develop into a highly profitable business. Photo from the site zont.ck.ua Moreover, if in the first case your hobby will require insignificant financial costs, then in the second case the greenhouse will be a significant investment, on the size of which your expenses for its maintenance will subsequently depend. Decide which model do you need: stationary or collapsible. Naturally, with a stationary model, the fuss is several times less - they installed it once and forgot. The collapsible one will have to be installed and disassembled twice a year, but if you are at the dacha only in the summer, and cases of thefts of dacha property have become more frequent in the village, then it is more expedient to purchase a collapsible one. Your final choice will also (and not least) depend on what exactly you are going to grow in the greenhouse. What to grow in a greenhouse?

In the greenhouse, you can grow tomatoes, greens, cucumbers, various seedlings and even berries - it's up to you, but keep in mind: different greenhouse crops differ in both growing modes and requirements for light and humidity. You can grow some plants together, while others will not tolerate any neighborhood and, moreover, will only harm each other. The articles will tell you more about this:

Once you have decided what kind of plants you are going to grow, you can choose a greenhouse of a suitable height. Agree: it is one thing to grow peppers, and quite another to grow cucumbers or tomatoes. So, if you decide to grow tomatoes, it is better to purchase a high rectangular greenhouse with a "house", it is this greenhouse that is ideal for tall plants. Having decided what you will grow, think about how what kind of growing system would be preferable. There are options:

  1. on the ground - soil (the most common growing system),
  2. or on various substrates (organic or mineral) - on peat mixtures, coconut substrate, expanded clay, tuff, perlite, mineral wool or vermiculite.

By the way, the irrigation system will also depend on the growing system - watering with a simple watering can, using a semi-automatic or fully automated system. Photo from sadoved.com

Or maybe you decide to grow plants using hydroponics - a method that is a system of growing and watering at the same time? If so, keep in mind that hydroponic systems also have several subspecies:

  • wick passive systems and intermittent flooding systems,
  • floating platform systems,
  • as well as aeroponic systems.

Naturally, which method you prefer will also depend on what kind of summer cottage you need. But if after buying a greenhouse it will be possible to somehow influence all of the above parameters, then it is unlikely to be at the place of its installation. That is why, before purchasing a greenhouse, decide exactly where it will be installed. A summer cottage must use sun energy with maximum productivity, and there may not be a lot of such places on the site, and their size also varies. You do not want to purchase a huge 10-meter greenhouse that ultimately simply will not fit on the planned installation site? Photo from the site img.bau.com.ua

Remember: greenhouses for summer cottages are installed in a place as protected as possible from wind and drafts.

Indeed, the external airflow directly affects the temperature regime inside the greenhouse, because of which the air can either suddenly heat up, or vice versa - excessively cool.

It is necessary to position the greenhouse in such a way that it is illuminated by the sun as much as possible throughout the day: it is advisable to install it in length from north to south.

Everyone, deciding to buy a greenhouse, hopes to minimize the cost of purchasing it, while the benefits should also be maximized. Let's try to figure it out: is this possible, and will the cost reduction lead to a significant deterioration in the performance of the greenhouse? Today, the market offers as never before a wide selection of greenhouses that are diverse in their shape, characteristics, size and price. For their production, new - as numerous manufacturers declare, higher quality, modern and reliable - covering materials, for example, cellular polycarbonate, are used. Polyethylene film is one of the cheapest and most widely used covering materials. Photo from the site vol-info.ru

It can be easily fixed on a greenhouse of any design, perfectly transmits ultraviolet rays necessary for the normal development of plants, and serves as an excellent protection for the “inhabitants” of the greenhouse from small frosts (up to -3 ° C). It has a density of 100 to 150 microns and a sleeve width of 1 to 3 meters.

Reinforced polyethylene film has the same advantages as ordinary film, but, thanks to a special reinforced mesh, it differs increased strength - it can withstand not only strong winds, but also hail. Photo from files.builderclub.com It is produced in rolls, the width of which is about 2 meters, with a density of 200 microns, and it can be used for several seasons in a row. Another popular covering material is spunbond - a durable white non-woven fabric that can easily withstand not only wind, hail, heavy rain, but also the onslaught of birds. Photo from the site shop.agreen.ua It is able to protect plants from frost down to -7 ° C, and it can be used for about 5 seasons in a row. By their shape, greenhouses can:

  • have a single or gable roof and vertical walls,
  • be arched, arched with vertical walls,
  • have the shape of a pyramid - a greenhouse-pyramid.

Perhaps the most common type is rectangular greenhouses - traditional, which most often have a gable roof. It is in such a greenhouse that it is easy to provide plants with optimal lighting. Photo from the site stroimdacha.ru In addition, it is very convenient and easy to use, which, you see, is also important. But let's see what other shape a summer cottage greenhouse can have. Greenhouses that are attached to the walls of buildings (houses, verandas, etc.) are called wall-mounted... As a rule, they have a pitched roof. Photo from the site www.teplitsa-s.narod.ru

They are deservedly considered one of the most economical, because thanks to such a design, it is possible to significantly save both on building materials and on placement, which, you see, is important, especially if the area of ​​the site is limited. There is practically no difference on which side of the building you attach a lean-to greenhouse, although it is advisable to direct the slope of its roof to the south side.

The arched greenhouse will be a real boon for thrifty gardeners. Photo from the site img-fotki.yandex.ru It costs quite inexpensively, and due to the fact that there are no sharp corners in its design, you will need several times less covering material than, for example, for a rectangular greenhouse of the same size. It is also thanks to this that its service life will significantly extend. Today, it is quite rare to see a pyramid greenhouse in garden plots, and this is due to the fact that it is an innovation in the world of greenhouses, which is established mainly by experimental gardeners. Photo from www.bochkavpechatleniy.com Both the advantages and disadvantages of the pyramid greenhouse are still unknown. The only thing that can be said with certainty: the pyramid greenhouse is distinguished by its spectacular shape and complexity of execution, although if there is a desire to build such a structure on your garden plot, then why not. A polygonal greenhouse (most often octahedral) is also quite rare. Photo from the site www.websadovod.ru

It is usually built of wood or metal in combination with glass. Such a greenhouse is quite practical, because each of its faces is heated at different times of the day rays of the sun.

For the sake of fairness, I will note: no matter what design a greenhouse has for a summer residence, it has both its advantages and disadvantages.

  • So, for example, cover arched greenhouse you can take just an hour, but it will be more difficult to take care of the plants growing in it: of course, access to the plants that grow near the aisle will be wonderful, which cannot be said about the plants planted in the extreme row - to get to them you will have to become on your knees.
  • In case of shed roof you can work in a greenhouse quite comfortably, but to cover such a roof, you will have to make a lot of effort - this must be done only in dry and necessarily calm weather, otherwise the film will flutter in the wind, and a little later it will simply sag. Of course, if you use glass or plastic instead of film, this problem will not arise.
  • Has its drawbacks and polygonal greenhouse: besides the fact that it is one of the most expensive, it is quite difficult to maintain a stable temperature in it. But on the other hand, thanks to its original form, it will become a worthy decoration of any garden plot.

What type of greenhouse to choose, to build it yourself or to purchase a ready-made one - it is, of course, up to you to decide. Photo from the site www.novostroy1.ru Consider only a few recommendations that are the same for all types of greenhouses. The optimal sizes of any summer cottage greenhouse are:

  • 2.5 meters - up to the ridge,
  • 1.5 meters - the height of the low wall,
  • 3.5 meters wide.

It is in a greenhouse with this size that it is easiest to care for plants. Naturally, these parameters are optional, you can change them at your discretion. The only greenhouse should not be more than 6 m in lengthy, otherwise it will be quite difficult to care for the plants in it. If a long greenhouse is absolutely necessary, divide it into several sections. Ideally, the doors to the greenhouse should be wide enough (about 1 meter) so that a garden cart or wheelbarrow can easily drive through them. The greenhouse frame can be made of metal, wood or plastic, but take into account the characteristics of these materials. Photo from the site prohladniy.g-o-r-o-d.ru So, the metal frame will be quite durable (it will last at least a decade), strong and relatively inexpensive. Photo from sadoved.com Wooden is unlikely to serve you for a long time, even if you treat it properly with good antiseptic agents, but it is quite cheap and easy to clean. Photo from www.albertahomegardening.com The frame made of plastic pipes will probably last the longest: it does not rot, does not need additional processing - painting, impregnation and so on, but it can deform in the sun. I really hope that the material presented in this article will be useful for you, and with its help you will be able to choose such a greenhouse that will satisfy all your requirements.

Do-it-yourself gable polycarbonate greenhouse: drawings, how to build, advantages and disadvantages

It is profitable to build greenhouses with a pitched roof for many reasons. Costs for building materials are reduced. If the frame of the greenhouse is attached to the south side of the house or other building, the occupied area will significantly decrease. In winter, less money is spent on heating, you do not need to go far when caring for plants. Some of the daylight is lost due to a blank wall, but this disadvantage can be eliminated by installing artificial lighting equipment.

Design features

One side of such buildings adjoins the wall of a brick house, garage or barn. Brick is not as susceptible to moisture damage as wood. It dries faster and does not rot if the joints and the entire surface are treated with special hydrophobic agents Siloxil or Funcosil. These preparations are environmentally friendly, water-repellent and not harmful to animals and plants.

The general view of a lean-to greenhouse resembles a one-piece construction of a free-standing greenhouse, but as if cut in two along its length. The material for the construction of the extension is selected by the gardener himself:

  • wooden frames made of timber or boards:
  • polyethylene pipes
  • metal corners or fittings
  • whole window frames with glazing and vents.

Covering materials are also varied:

  • glass
  • cellular polycarbonate
  • PVC film
  • a combination of all named hideouts.

The type of construction depends on the selected material. The roof of wooden greenhouses from a bar and structures from old windows looks like a right-angled triangle. Its highest part adjoins the blank wall of the fence. The presence of opening vents is convenient for ventilating the greenhouse.

The roof of polycarbonate greenhouses can be built in the same way or be rounded in the form of a hemisphere. Plastic sheeting is used for many types of outbuildings.

Benefits and losses

Before starting construction, the owners evaluate many nuances: the choice of location, the purpose of using the greenhouse, suitable materials.

Lack of usable space (for experienced gardeners)

Small footprint for basic plant care training (for beginners)

Loss of natural light. The sun's rays do not illuminate all areas in the greenhouse room

Separate room for growing seedlings

Proximity to a residential building. Risk of damage to building communications

Savings on building materials, heating, lighting and automatic irrigation

Protection of the extension from wind and cold from the side of the main wall

The stability and reliability of the entire attached structure is ensured by fastening to the wall

Assembling a polycarbonate coated greenhouse

For a greenhouse with a pitched roof, cellular polycarbonate will be the best covering. It is a strong and durable material from which you can form both a triangular and a hemispherical roof shape.

Step one: preparation

Before the main assembly of the structure, they determine the place for the greenhouse, clear and mark the site for construction. The size of the future greenhouse determines what kind of foundation is needed. For large rooms, choose a strong concrete base. Lighter structures are installed on a soil, wood or brick foundation.

The necessary tools should always be at hand during assembly work, therefore, a set is prepared in advance, which includes:

  • one straight and one Phillips screwdriver
  • socket wrench 8 mm
  • electric drill or screwdriver
  • sharp cutter for cutting out polycarbonate blanks
  • fasteners: bolts, screws, nails, nuts
  • additional tools: twine or cord, building level, hammer and shovel.

All parameters are marked on a diagram developed by the owner or designer. According to the dimensions plotted on the plan, the amount of material required is calculated.

Step two: assembly

Novice summer residents experience some difficulties in organizing a step-by-step installation procedure. We offer the following sequence of work execution:

  1. Choose a place for an extension. A brick wall on the south side of the house, fence or shed would be the best option. You can install a greenhouse near wooden buildings, but keep in mind that the moisture in the greenhouse premises quickly destroys the tree.
  2. Prepare the site. Level the building land, mark the greenhouse according to the size of the greenhouse using a tape measure, pegs and twine.
  3. Treat the supporting walls with means that protect them from moisture penetration. It is better to do this twice with an interval of 2 days.
  4. Assemble the frame from the prepared materials: wooden blocks, metal corners or plastic profiles. All dimensions are checked against the project and fastened together with fasteners.
  5. Fix the frame to the wall. Check the reliability of the structure. Accuracy of assembly must be verified at the building level.
  6. Cut out fragments of the single-pitched greenhouse cladding from polycarbonate sheets. Their sizes should be indicated on the diagram, but it is better to check everything according to the actual parameters. Small deviations may occur during assembly.
  7. Fasten all the fragments to the frame using bolts and a wrench.
  8. Seal butt joints with sealants.

Tips & Tricks

The following optimal sizes are recommended for single-pitched greenhouses:

  • height - 1.8 - 2 meters
  • frame length - 3-4 m, beds - up to 0.8 m
  • width - 1.7 - 2.5 m, passage between the beds - up to 1 m
  • roof inclination angle - from 30 to 60 °
  • ventilation windows (2-3 pcs.) square or rectangular - 50x50 or 50x70 cm.

The foundation is made depending on the weight of the structure, as well as seasonal or year-round use. It can be:

  • subgrade for small lightweight outbuildings that are used only in summer
  • block foundation made of wooden beams for greenhouses for spring-autumn use
  • strip monolithic concrete foundation for heavy structures with continuous operation throughout the year.

The assembly of single-pitched greenhouses begins with a lower strapping made of a bar with a cross section of up to 100 mm. Then the lateral vertical posts from a 50 mm bar are installed and fastened. The roof is assembled separately from boards and slats, sheathed with polycarbonate sheets. Raise the roof and fasten it first to the supporting wall, then to the upper strapping of the greenhouse frame.

If the dimensions of the wall for the extension are minimal, but still there is a need to build a greenhouse for growing seedlings, you can make it very small, the size of one or two window frames. The assembly of such a structure takes no more than 2 hours, there are no difficulties during installation, the costs will not exceed the budget.

For this, the area near the wall is cleaned, leveled and tamped. A board is fastened to the wall at a height of 60 cm. At a distance of 80 cm from the wall, a timber of 50x50 mm is laid. Two glazed frames from old windows are placed on these supporting elements and hinges are installed. The lateral triangular ends are covered with plastic wrap.

An annex to the house in the form of a lean-to greenhouse can be used in winter. Heating, additional lighting and water supply systems are connected to general communications.The costs are minimal, and the benefits are enormous. This is the provision of the family with fresh herbs, vegetables, as well as a kind of decoration of the garden.

Single-slope greenhouses, attached to the walls of the house, serve as an element of the adjoining exterior. Flowers and climbing plants can be grown in hanging boxes and pots. They diversify with their beauty the monochrome winter landscape.

Conclusion

Construction of lean-to greenhouses does not take much time. In such buildings, benefit and beauty are combined. Here plants are grown, which, with their appearance, enliven the site, delight the eye. Summer residents get satisfaction from their work. The skills acquired during construction will be useful to them in further work on the improvement of the garden and the entire local area.


Spunbond structure and characteristics

Spunbond is a nonwoven fabric made from polypropylene fibers. It is produced by the method of thermal bonding: polypropylene is heated to high temperatures, after which it is split into thousands of small fibers, which are interconnected under the influence of heat. The result is a durable polymeric material with a non-woven structure. To protect it from ultraviolet radiation, the spunbond is additionally treated with light stabilizers.

Spunbond is a lightweight and environmentally friendly material, polypropylene fiber does not emit toxic substances and can be used to protect cultivated plants. Manufacturers produce fabrics with a density of 15 g / m2 and up to 160 g / m2 - this parameter determines the possibilities of use. The standard roll width is 1.6 meters, but widths from 0.8 to 3.2 m are available.

Spunbond has the following properties and characteristics:

  1. Low weight. The rolls seem to be practically weightless, they do not put additional stress on the structure of greenhouses and greenhouses.
  2. Resistance to natural factors. The material based on polymer fiber does not rot, is not destroyed by fungus and mold. In addition, it is not touched by birds, rodents and insects.
  3. Environmental friendliness. Even when strongly heated by the sun's rays, polypropylene does not release toxic emissions into the environment.
  4. Air and moisture permeability. Unlike a film, such a covering material provides natural air exchange necessary for normal plant growth, and also does not interfere with the penetration of rain moisture. At the same time, the spunbond itself does not get wet and is not afraid of high humidity.
  5. Low thermal conductivity. Such a covering material protects plants from the sun's rays, and also prevents freezing during frosts. These properties provided spunbond with high demand in agriculture.
  6. Light transmission. It depends on the density, but all types of spunbond pass the sun's rays to one degree or another. This provides good conditions for the growth of plants, while protecting them from overheating.

An important advantage is the low cost of the material. It is cheaper than other types of covering materials, therefore it is in demand among farmers and gardeners.


HOW TO CHOOSE A CONSTRUCTION TEAM?

You can manage the repair process yourself, and hire performers for various types of work. This method is suitable for those who have a lot of free time and strong nerves, but lack of finance. But keep in mind that it is suitable only for cosmetic repairs, without complex types of work and redevelopment. The advantage of this method is cost savings. After all, the prices of private teams are lower than those of specialized companies. In addition, you do not have to pay for the services of a foreman. Well, if during the repair you run out of money, you can interrupt it at any stage: you will not have to pay a penalty under the contract. True, only a person who is well versed in repair processes can control the quality of work. And it is quite difficult to be confident in the knowledge and skills of future employees. Ideally, you should visit the objects that the team led in order to personally assess the quality of the work they performed. The difficulty also lies in the fact that no contract is usually concluded with a private brigade. Often these are not legal entities, but individuals. Legally, they are not responsible for their actions, and in which case it will not be possible to bring them to justice. An important point: it is better to invite qualified specialists from licensed companies to install and debug engineering and technical equipment.

Another option is to contact a repair and construction company, hire a foreman and conclude an agreement with him to manage the overall redevelopment process. He will lead the work of the brigade: he will set tasks for it, indicate the sequence of work, control the quality of their implementation, as well as the quality of supplied finishing and building materials. Better if the foreman comes

and with his brigade. After all, conflicts may arise with the team hired by the customer. It is desirable that an agreement be concluded between the foreman and the customer, where all his duties and terms of work are clearly spelled out. Only in this case the foreman is legally responsible for the work performed. The services of a foreman will help save you time, but they will not be cheap. And you can be sure that everything will be done correctly during the repair process only if the foreman is a competent specialist.

3. TRUSTING THE PROFESSIONALS

If complex types of repairs and redevelopment are planned, then it is worth concluding an agreement with a serious repair and construction company. Indeed, to obtain all the documents certifying the legality of the reconstruction or redevelopment, you will definitely need acts of hidden work that will not be visible after the completion of the repair. They must be signed by representatives of the contractor, customer and field supervision. If the repair is done by a company that has a permit of a self-regulatory organization for construction (SRO approval), then it itself fills out acts on the work performed. But if the repair is carried out by a private team, then each time you will have to contact an organization that has an SRO permit and will draw up acts of hidden work.

The second option is inconvenient and unprofitable. It should be noted that in case of redevelopment, it is necessary to conclude a civil liability insurance contract. More likely to conclude it if the workers are sent by a company licensed to carry out such activities.

When concluding a contract with a contractor, you need to pay attention to the list of works, the exact timing of each separate stage, the amount of payment and the estimate drawn up. Agree that you will pay in installments and only for the work performed, and give no more than 20% advance. The firm's budget should be very clear. Some unscrupulous companies attract customers with tempting prices, not including in the estimate a number of works that will definitely be needed during the repair process. As a result, unplanned expenses await you, and the estimate can double. It makes sense to contact several companies and compare their estimates for price and content. But the agreement does not guarantee your complete peace of mind. You still have to control the process at every stage, keep track of what materials are purchased and how much money is spent on it.
