Convertible greenhouse with removable polycarbonate roof

Greenhouse Convertible

• frame – double galvanized square pipe 20x20x1mm;
• 2 doors, 2 windows;
• step between arcs 1 m;
• bolted crab mounting;
• width – 2.5 or 3m, height – 2.1m, length – 4, 6, 8, etc.
• opening top and side walls.

The Moscow region, like the entire central zone of Russia, is considered a region of risky agriculture. The climate, not as harsh as in the Urals or Siberia, increasingly brings surprises. Including unpleasant ones. Too much snow in winter, severe frosts, freezing rains - every summer resident has to deal with this. What about the warm season, with frosts in early and mid-May, unexpectedly cold June and intense heat in July and August?

In order to grow a good harvest and reduce risks to a minimum, one greenhouse or a more solid structure will not be enough. We need something more perfect and thoughtful. Such as the “Convertible” greenhouse with a removable roof and double arches. It is produced in our company, whose specialists can not only manufacture the product according to your measurements, but also deliver and assemble it on site. This is very inexpensive and convenient for those who want to do only gardening and do not have a set of tools.

Advantages of the model

They are obvious, but it is worth dwelling on some features in more detail. The main advantages include:

• Ease of use.
• Durability.
• High strength.
• No problems with snow drifts.

So, it has a convertible top. It can be removed completely and put back in place if necessary. Like the car of the same name, this “roof” promotes better ventilation. The air will circulate inside much more intensively than with the door and window open. This will reduce excessively high temperatures and humidity.

Gardeners will appreciate the removable top part both in summer and winter. In July and August, on the hottest and hottest days, it becomes impossible to breathe in it. Plants sometimes die and do not produce the harvest that they could bring to the owner. A simple way to ventilate a “room” is not always effective, and it is better to remove part of the covering altogether.

In winter, problems arise with snow caps. The rigid pipes from which the structure is made do not always help. Over time, the load on polycarbonate becomes too high and it cracks. It’s easier not to interfere with snow and remove the covering in the off-season, unless, of course, you plan to spend money on heating and grow greens in November-December. By spring you will have everything back in place.

How to order?

Those who have been gardening for a long time have probably tried to find and buy a greenhouse with a removable polycarbonate roof in Moscow. This was not so easy to do: not all manufacturers agreed to manufacture according to an individual project, and such models simply were not available in the basic assortment.

However, now there will be no problems with the search. We manufacture products with non-standard designs. We create and implement solutions in our production that any summer residents will appreciate. To use our services and place an order, just call. In a few days, materials will be delivered to your dacha and a new “house” for heat-loving plants will be installed.

Polycarbonate greenhouse with a removable roof: user reviews

Greenhouses with removable roofs have become very popular among farmers. Such greenhouses have found application both in private use and for industrial cultivation of vegetables.

The main purpose of an opening greenhouse is to ventilate the structure in warm weather, when the windows and doors are not enough for air to enter.

All the advantages of a greenhouse with a removable roof can only be appreciated after its use. It is not necessary to buy a ready-made structure; if necessary, you can assemble it yourself from inexpensive materials.

Positive points:

1. In winter, snow falls through the open roof of the greenhouse onto the ground, moisturizes and nourishes it, and prevents it from freezing and drying out.
2. Heavy snow covers can damage the frame of the greenhouse if it is not removed promptly. The arched design with an opening roof allows snow to accumulate inside the greenhouse rather than on the roof.
3. The polycarbonate coating conducts light well. If the weather is warm outside, you can open the roof to allow the plants in the greenhouse to have direct access to sunlight.
4. A removable roof can completely replace ventilation in the warm season. In hot weather, to prevent plants from steaming under the roof, you can open the doors and open access to fresh air.
5. Such a greenhouse is very easy to install; it does not require a special foundation, since the structure is not very heavy.

As a rule, the roof of a greenhouse should be removed very quickly and without much effort. To do this, curved polycarbonate sheets are inserted into a profile with grooves, along which they will move smoothly and are equipped with special latches. Once one of the roof sections is opened, it can be easily secured.

Excellent illumination

Plants in a greenhouse require light. In closed ground you cannot find the same amount of light as in open ground. Even the best polycarbonate is capable of absorbing certain spectra.

Therefore, polycarbonate greenhouses with an opening top are very popular, and in this case they use a removable roof. The sun's rays will hit the leaves of the pepper or tomato directly, without the use of artificial phytolamps.

Normalization of microclimate

A ventilated roof is perhaps the best way to get rid of the hot air that accumulates under the ceiling of the greenhouse.

The hottest air collects at the top of the greenhouse. Such a roof will be the most effective way of ventilation. Ordinary side windows will only chill the plants.

It is noted that many industrial greenhouses have vents in the doors or above the doors. This design solution is associated with saving metal, and not with accurate calculations.

Saving on strength

The most important advantage of such a greenhouse is the use of a lightweight design. You don't need to use supports here. You can build greenhouses from the cheapest plasterboard profile so as not to worry about withstanding snow loads. Many summer residents are afraid of this new product, lest the roof be blown away by the wind.

Therefore, it is worth choosing a stable and good design. This opinion is dubious; here we are talking about the “windage” of the greenhouse.

Convenient greenhouse “Convertible” with a removable roof

A popular type of greenhouse with a removable roof is the Flora-Cabriolet design. The roof in this greenhouse moves down and up thanks to the special laying of polycarbonate sheets.

In the open position, the sections do not move - they are fastened together with special latches. Most often, the latches are made of high-quality metal that is not subject to corrosion, but if the latches are damaged, they can be easily replaced.

Greenhouse Convertible and what are its advantages

As numerous reviews testify, the convenience of a convertible greenhouse is undeniable. For example, in winter, owners of such structures are freed from the need to visit their dacha to sweep away snow from a fragile structure.

A removable roof also has the following advantage: snow freely falls into the open greenhouse, which helps:

• ensure soil moisture;
• protect the beds from freezing;
• ensure normal ventilation in the summer;
• save on the frame (you will need a lighter one, because it will not have to withstand precipitation).

As with everything new, people treat convertible-type greenhouses with a certain wariness. The experience of gardeners who have already installed such protective structures on their plots suggests that their previous fears turned out to be completely unfounded.

Do-it-yourself compact greenhouse with a roof: important details

Before assembling the greenhouse structure, you need to decide on the location for its placement. The area must be cleared of roots and bushes, the layer of soil must be leveled as much as possible.

To strengthen a stationary structure, you need to prepare a foundation. Solid - if the greenhouse is large, strip - for a small greenhouse.

The place should be quiet, hidden from the wind. There should be no buildings or tall trees near the future greenhouse that could obscure the sunlight. The right location is the key to a great harvest!

The construction of a greenhouse with a removable top is practically no different from a regular greenhouse. The only difference is the installation of the roof top, which will tilt or slide. As a rule, polycarbonate sheets are mounted in special grooves. If necessary, part of the greenhouse can be folded up or part of it removed (as in the Matryoshka greenhouse).

To improve the product, you can equip the greenhouse with a special mechanism. The principle of its operation is that when the air inside heats up to a certain temperature, the mechanism is triggered and opens the hatch for ventilation.

Many summer residents install removable roofs for the spring and summer, and in the fall, after harvesting, they remove the covering, leaving only the frame. In this case, the tightness is lost and the strength of the polycarbonate is compromised, which has to be mounted back and forth frequently.

Gable greenhouse "Delta" with removable roof

This greenhouse is very similar to many other gable structures with a polycarbonate coating. The peculiarity of the Delta greenhouse is the ability to slightly open part of the roof in the summer or completely dismantle it in the winter. You just need to pull the small handle and open or remove the roof completely.

A greenhouse with a removable roof is not afraid of snowy winters - you just need to remove the roof and not worry about the soil inside the greenhouse. Also, you will not be affected by the problem of removing snow from the roof slopes.

The frame of the Delta gable greenhouse is made of galvanized pipes with a cross-section of 2 cm, which are resistant to corrosion.

The width of the greenhouse is 2.5 meters, the length ranges from 2.2 to 10.6 m. Despite the lightness of the structure, experts recommend installing it on a brick strip foundation in order to avoid subsidence into the ground.

The greenhouse kit includes a frame and cut polycarbonate sheets, which only need to be inserted into the grooves for sliding. You can do this yourself without the help of specialists. The roof can be opened all the way or partially opened to ventilate the greenhouse.

Review of ready-made greenhouses with sliding top

There are ready-made solutions and projects for both small and large greenhouses, here are some of them.

Greenhouse design "Nurse-Clever"

This type includes a steel pipe with a cross section of 20 by 20 mm. The arcs are located every meter. They are shaped like an arch. The thickness of the walls of the “Nurse-Umnitsa” is 1.5 mm, and the width is 3 mm. The length is about 8 meters.

Some models of the “Nurse-Clever Nurse” greenhouse design have a thickness of 1-2 mm. At first glance it may seem that the frame is rather flimsy, but it is not so. Owners of such greenhouses always express their extreme admiration for their reliability.

Greenhouse "Delta"

In order to open or remove the top a little, you just need to pull the handle a little. This design is easily ventilated in summer. To do this you need to move the top a little. In winter, it is important to remember to remove the top.

Snow that covers the soil in winter will protect it from possible freezing. The Delta doors are divided into upper and lower. This fact provides ventilation.

Greenhouse structure "Omega"

It is important to note that the pipe included in the structure consists of galvanized steel. In the Omega greenhouse, the pipe has certain protection inside and outside.

Many greenhouse products are powder coated. Their service life is a maximum of 5 years. This is due to the fact that the pipe is unprotected. The Omega greenhouse is considered very durable. It can withstand more than 320 kg per 1 sq.m.

Greenhouse "Present"

There are sliding panels that are inserted into special grooves. They can be moved down. In summer, the panels can be opened slightly and lowered down in winter.

For good illumination, the arcs are installed at a distance of two meters.

It is quite acceptable for a greenhouse structure of such high quality. It is possible to order delivery.

It is carried out in cities such as Ufa, Novgorod, St. Petersburg, Moscow and Novosibirsk.

Greenhouse structure "Orion"

Greenhouse structure "Oasis"

This structure is made of galvanized steel. The greenhouse structure is 4 meters long, 3 meters wide and 2 meters high.

Advantages of the device

Having a polycarbonate greenhouse on the farm, the owners, not without reason, worry about its safety during winter snowfalls. It is not always possible to periodically visit the site to clear snow. By installing a structure with a removable roof, a plant growing enthusiast receives significant advantages:

1. Enriched soil. Precipitation falling on the beds in a greenhouse with a removable roof retains moisture and serves as protection against desalination. Snow prevents beneficial microorganisms from freezing out in the soil, without which the soil quickly becomes depleted. Experienced specialists are convinced of the advantage of maintaining the natural environment of the soil, rather than subjecting it to regular replacement, risking acquiring a new infection or parasites.
2. Structural strength. Wet snow poses a particular danger to a polycarbonate greenhouse, even if it is gable. The ice crust formed during the thaw further retains the snow cover, increasing the risk of damage not only to the roof, but also to the entire frame as a whole.
3. Overheating prevention and microclimate optimization. The advantages of a greenhouse with a removable polycarbonate roof also appear during the warm season. It is optimal to provide a device where the roof is not only removed, but also moved back or raised. Exceeding the optimal temperature for plants leads to sterilization of pollen and absence of ovary. Often, the vents do not cope with their functions, and a removable roof will ensure uniform ventilation without drafts. A polycarbonate greenhouse allows the sun's rays to pass through well, but periodically providing natural light to plants is a very useful activity.
4. A polycarbonate greenhouse with a removable roof will save on building materials. The design does not require additional reinforcement to withstand snow cover; it can be made in a lightweight version.

Advantages of pop-up greenhouses

Greenhouse structures with an opening top have many positive characteristics. One of the main advantages is the fairly low cost. The cost of such a greenhouse is only 5% more than the price of simpler greenhouse structures.

The advantages of a greenhouse with an opening top include such technical characteristics as:

• Snow supports the frame, from the outside and inside . Because of this, the pressure exerted by wet snow on the greenhouse frame is balanced. Greenhouses whose roofs open have a long service life.
• Snow gets inside the greenhouse structure due to the removable top. It covers the soil with a thick layer. This has a positive effect on the composition of the earth. Thanks to this factor, the soil will be protected from drying out and desalination. Also, a dense snow layer allows you to avoid the extinction of essential microorganisms. Thanks to this, you can avoid the entry of harmful microorganisms and any parasites.
• Thanks to the folding top, a high level of sunlight is guaranteed. While polycarbonate is able to completely absorb the necessary light spectra. Because of this, there is a lack of sunlight.
• The opening top provides 100% protection against overheating. It is an excellent alternative to a regular window. Ventilation occurs evenly and drafts do not form.
• The positive aspects of greenhouses with an opening top include quick assembly.

Design options

The greenhouse models with a removable roof offered today have a very important property - ease of installation. Whether you plan to purchase blanks or do all the work yourself, you need to pay close attention to this feature.

Cabriolet

Convertible greenhouses have various design options, with the main goal of maintaining the integrity of the structure in the winter, ensuring precipitation reaches the soil and performing ventilation functions in the warm season.

In the proposed arched form of a convertible greenhouse, the configuration is characterized by the following parameters:

• the facade is made of a 2.0 x 2.0 cm profile pipe, the material is all-welded steel, coated with white powder paint;
• width is 2.8 m, height – 2.2 m, length varies from 4 m at the request of the customer;
• distance between arches – 1 m;
• there are 2 windows and 2 doors;
• 9 ties and pins are included to secure the frame to the ground.

In the greenhouse, the convertible polycarbonate is inserted into a profile with grooves; it is quite easy to slide it down by hand. To fix the roof and prevent it from opening on its own from the side, special clamps are used.

Convertible flora greenhouses with a removable roof can satisfy the demanding consumer. The range includes seven options of different lengths - from 4 to 10 meters. If desired, an additional polycarbonate partition is installed, which allows you to maintain a different microclimate for the planted crops, an automatic ventilation system and, if necessary, another window.

Matryoshka

A matryoshka greenhouse with a removable roof functions differently. Its polycarbonate sections are superimposed on one another according to the principle of a pencil case. The construction, carried out at a professional level, has the following characteristic features:

• The frame of the greenhouse with a removable roof is made of a galvanized square closed pipe with a cross-section of 2.5x2.5 cm.
• due to double arcs, the greenhouse roof can withstand a load of 85 kg/m2; when the panels are removed, the figure increases to 200 kg/m2;
• the greenhouse is 3 m wide, the length ranges from 3 to 7 meters depending on the wishes of the customer;
• by cutting polycarbonate panels along the channel, the likelihood of mold from evaporation and humidity is eliminated;
• To dismantle the removable polycarbonate roof, you will need to manually unscrew the nuts;
• the assembled greenhouse can fit into a passenger car; the polycarbonate panels are rolled into a roll 1 m high;
• a polycarbonate greenhouse can withstand temperatures ranging from -40 to +100C o.

The frame of the Matryoshka greenhouse can be used for 30 years.

Design Features

The offered versions have a different opening mechanism, which determines the difficulty of making it yourself and, accordingly, the cost.

Let's list some features:

• A convertible is rectangular with a sloping top, divided into equal segments. The structure opens by dropping a segment. Thus, the internal space is completely revealed;

• Greenhouse Convertible Flora with a removable roof is a simplified form of the basic model - only the top folds down;
• Delta is the simplest and most classic greenhouse with a removable polycarbonate roof. It has the shape of a house, the top of which opens by sliding down;

• A similar universal model that allows you to open the entire interior space to the sun is the version with a horizontal mechanism. Assumes sliding sections horizontally. This version can also be used for backyard swimming pools;

Device for opening the roof of a greenhouse

The finished models are made using high-quality metal-plastic fittings, guaranteeing multiple cycles of operation. It includes a locking mechanism and seals that allow the structure to be hermetically sealed for the autumn-winter period. The listed samples were developed and sold by the Izhevsk company Novator, which also offers designs of the same name. For example, this is a Novator-5 greenhouse with a removable roof.

Features of construction

There are several ways to solve the issue of constructing a greenhouse with an opening polycarbonate roof:

• purchase a complete set of the model you like and pay for the installation of the structure;
• buy a frame, reserving the right to independently select the foundation, polycarbonate panels and install the greenhouse;
• assemble a greenhouse with a removable roof with your own hands from your own materials.

Each option has its own characteristics.

Installation of ready-made structures

A greenhouse with a removable roof, manufactured in an industrial environment, is certainly accompanied by assembly instructions. A prerequisite for the correct installation of a convertible greenhouse is a prepared, flat surface of the site. The frame is mounted without major tightening of connections. Final fastening is carried out after assembly is completed and verification testing has been completed. Having previously secured the connecting nodes, they proceed to covering with polycarbonate, after which the greenhouse becomes stable and is not afraid of natural disasters.

Significantly more actions involve individual production.

DIY construction

Making an opening roof in a greenhouse yourself is a completely doable task. The solution comes in the form of a frame structure with the ability to be easily dismantled for the winter. Construction is progressing in stages:

• Initially, a greenhouse frame with a removable roof is assembled from a galvanized profile. Before installing the vertical posts, their lower ends are attached to a 40/40 angle made of steel.
• A support section is attached to the corner at a right angle to prevent the profile from sinking into the soil.
• For a removable roof, a triangular arch is assembled from a profile. Stability is ensured by crossbars and jibs.
• The racks in the lower part of the greenhouse with a removable roof are sheathed with boards, and polystyrene foam packed in plastic bags is placed inside. Connections are made with blind rivets.
• To assemble the frames, strips are used, cut at an angle of 45°, connected with glue and tightened with self-tapping screws.
• The frame seal is glued to the back of the strip.

To install a polycarbonate frame into the frame of a greenhouse with a removable roof, metal furniture corners are used.

The process of connecting a polycarbonate frame to a frame is quite simple and resembles the design of a mosquito net in a plastic window:

• we insert the upper corners of the frame into the frame;
• bring the bottom edge all the way;
• We move the frame down until it engages with the frame.

When dismantling the structure, the steps are performed in the reverse order.

Replacing old windows in your home with plastic ones frees up a lot of window frames that can also be used for a greenhouse with a removable roof. For this you will need:

• lay the foundation out of brick in one row, covering it with roofing felt;
• a 5x5 cm beam is laid on the foundation for attaching frames to it;
• after installing the racks, the ridge with rafters is attached;
• for an opening roof, 2 stops made of slats are attached to the frames;
• during the warm season, the frames are raised and fixed; in the winter season, the screws are unscrewed and the frames are dismantled.

Each model of a greenhouse with a removable roof has its own advantages: the independent manufacturing option saves money, the purchase of a convertible structure made from polycarbonate industrially is the key to high quality and long-term operation.

Features of use

Now, to prevent the polycarbonate greenhouse from breaking due to winter snowfalls and to obtain an excellent harvest, you just need to move it aside. When you leave your dacha in the fall, it is enough to spend 10 minutes to move the roof of the greenhouse and not remember about it all winter. You won't need to go to the dacha to shake the snow.

To prepare the greenhouse for winter, it will be enough to remove the clips that secure the polycarbonate, and then slide the 1 m wide sheet down. This will protect the greenhouse in winter, and beneficial precipitation will be able to fall to the ground. Thus, in the summer you can easily ventilate the greenhouse or completely remove the roof.

In the greenhouse, tomatoes do not get sick, there are no drafts, and there is no condensation. The fruits will be able to set without additional shaking due to the presence of air flow at the top of the greenhouse. The harvest is becoming excellent.

Design

In the Flora-Cabriolet greenhouse, you can move the polycarbonate from the roof at any time. A polycarbonate sheet with a width of 1 meter is inserted into profile grooves, along which it can freely move down in any direction. It is moved to the required distance or removed completely. When the greenhouse is closed, to provide protection from wind loads, the polycarbonate is fixed with special clips on the sides.

Opening the roof of the greenhouse allows for excellent ventilation for the crops being grown.

1. The greenhouse has a collapsible frame with straight walls 2 meters high.
2. At the base there is a four-meter professional pipe 30x20, which can be increased by 2 m.
3. The arches have three parts: an upper truss and two straight posts.
4. A total of 9 rows of ties and a base are used.
5. Between arcs - 1 m.
6. Guides, bases, and arcs are connected using the “pipe-to-pipe” method, which significantly simplifies assembly and also increases the rigidity of the structure.
7. Dimensions: length – any, width – 2.8 m, height – 2.2 m.

The greenhouse is equipped with two doors, two windows, fasteners and a full set of fittings, which includes foundation fastening and assembly instructions.

Polymer powder coating from Italy is used to paint the greenhouse. The coating is baked in a special oven.

Premium class cellular polycarbonate with parameters of 700 g/m2 is used. Time of use – at least 10 years.

Caring for greenhouses with an opening roof

High-quality greenhouses can last quite a long time, but this requires proper care. Basically it consists of preparing the greenhouse for winter.

It consists of the following stages:

• Remove vegetation, shelves and containers.
• Treatment of the top layer of soil.
• Washing the walls.
• The walls need to dry.

After all these steps, you can be sure that the greenhouse is ready for the winter period.

The advantage of a greenhouse with a removable top

Living soil

Everyone knows about the benefits of snow cover for the earth. When using closed greenhouses, the ground may freeze and beneficial microorganisms disappear. This desalinizes the soil, so summer residents change the soil every 2 to 3 years.

If you remove the roof from the greenhouse, snow will fall on the beds all winter, covering the ground. This will ensure moisture retention in the soil, prevent it from turning into dust and drying out, and also protect against desalination. The presence of natural snow cover will protect beneficial microorganisms from freezing in the soil. If greenhouse beds are deprived of it, the soil quickly becomes depleted. Experienced greenhouse growers are convinced that it is better to maintain living soil in the greenhouse than to replace it every two years.

As a result, time and money are saved.

Frame strength

There is no need to select durable greenhouse options that can withstand snowfalls in winter. No roof - no problem.

During one winter, a significant amount of snow can accumulate on the greenhouse. Wet snow is especially dangerous. Now even powerful versions of advertised greenhouses can completely collapse during a snowy winter. Arched polycarbonate greenhouses can bend inward from snow. There can only be one solution here - the snow must fall inside the greenhouse.

overheat protection

A removable greenhouse in summer is also a very good option. Even when using windows, the temperature inside the greenhouse can be 45°C, which can negatively affect the harvest. Popularly, this process is called “overheating” of plants, which is more dangerous than drafts. Open doors at the ends of the greenhouse may not be enough to save plants from overheating, and ventilation holes are generally small in size. The Convertible greenhouse can be easily ventilated by removing certain elements of the roof. This type of ventilation is characterized by uniformity and the absence of drafts.

Excellent illumination

Plants in a greenhouse require light. In closed ground you cannot find the same amount of light as in open ground. Even the best polycarbonate is capable of absorbing certain spectra. Therefore, polycarbonate greenhouses with an opening top are very popular, and in this case they use a removable roof. The sun's rays will hit the leaves of the pepper or tomato directly, without the use of artificial phytolamps.

Normalization of microclimate

The hottest air collects at the top of the greenhouse. Such a roof will be the most effective way of ventilation. Ordinary side windows will only chill the plants. It is noted that many industrial greenhouses have vents in the doors or above the doors. This design solution is associated with saving metal, and not with accurate calculations.

Saving on strength

The most important advantage of such a greenhouse is the use of a lightweight design. You don't need to use supports here. You can build greenhouses from the cheapest plasterboard profile so as not to worry about withstanding snow loads. Many summer residents are afraid of this new product, lest the roof be blown away by the wind. Therefore, it is worth choosing a stable and good design. This opinion is dubious; here we are talking about the “windage” of the greenhouse.

7 ADVANTAGES of a greenhouse with a removable top

1. Living soil

I think there is no need to explain the benefits of snow cover for the earth. In closed greenhouses, the soil freezes, beneficial microorganisms die, the soil becomes desalted and dries out - the soil has to be completely changed every 2-3 years.

In greenhouses with a removable roof, snow falls directly onto the beds all winter, covering our dear soil. This not only retains moisture in the soil and prevents it from drying out and turning into dust, but also protects against desalination. Natural snow cover also protects beneficial microorganisms in the soil from freezing. If you deprive greenhouse beds of it, the soil in them will quickly deplete. As experienced greenhouse growers are convinced, it is better to keep the soil in the greenhouse alive than to completely change it every two years, introducing new infections and parasites with the new soil.

As a result, we save time (no need to throw snow inside the greenhouse) and money (soil is expensive these days)

2. Frame strength

The most obvious one is that you don’t need to choose the most durable greenhouse that can withstand snowfalls in winter. Everything is simple here - no roof, no problem. Let's forget about supports, about weekend trips to the dacha to dump snow - we save time and nerves.

. If, due to inexperience, it seems that the snow is not so heavy, you are mistaken. In one winter, it will accumulate in the greenhouse as much as a whole company of soldiers would stand on it at the same time, and not just two people happily hanging, as is usually depicted on advertising brochures. It's tons and tons, and wet snow is especially dangerous. Unfortunately, even the most advertised “powerful” greenhouses have the ability to completely collapse in snowy winters. Also, you yourself may have noticed more than once in photographs and in life how the polycarbonate walls of the arched greenhouse bend inward - from the snow. This is no wonder, because the snow puts pressure not only on the roof. And this is a significant reduction in the life of the entire structure. There is only one solution - so that the snow falls easily and without obstacles inside the greenhouse and also accumulates near its walls, as well as outside. This equalizes the pressure.

3. Overheat protection

A removable greenhouse roof is also good for the summer. Even with vents, the temperature inside the greenhouse can reach as much as 45°C, and this is a direct path to pollen sterilization, the absence of ovaries and, as one would expect, not a single fruit. This is popularly called “overheating” the plants, which can be much more dangerous than letting them through. And it happens that even open doors at the ends of the greenhouse are not enough to save the plants from overheating, and the ventilation holes are even made small. It is easy to ventilate such greenhouses by opening one of the removable roof elements or all of them at once. In addition, such ventilation is uniform and draft-free, which is also very valuable.

4. Excellent illumination

You know very well how much light the plants in a greenhouse need. And the same quantity as in open ground cannot be found in closed ground. Even the highest quality polycarbonate absorbs some spectra - why not make the roof removable? Let the sun's rays caress the leaves of a tomato or pepper directly, and not with the help of artificial and dubious phytolamps.

5. Normalization of the microclimate

After all, it is under the top of the greenhouse that the hottest air collects. Such a roof is the most effective ventilation, while ordinary side vents often only chill the plants. Something similar was once implemented by Jacob Mittleider, and a removable roof is the next stage. But then you ask: why do most industrial greenhouses have windows either in the doors or above the doors? In fact, this is the simplest design solution and saving of metal, and not at all an exact calculation.

6. Saving on strength

And the most important advantage is that such a greenhouse can be built with a lightweight design and completely forget about supports. You can safely build even from the cheapest plasterboard profiles and no longer worry that they will not withstand snow loads. Why, then, with all the advantages, such a greenhouse is no longer located on every site? The fact is that many are still afraid of such a new product - they say that after a thunderstorm they will have to look for a roof in neighboring areas. That's why it's important to choose a good and stable design, agree. Those. We are talking about the so-called “windage” of the greenhouse, namely its resistance to wind. Although, we note, the owners of such unusual structures claim that none have flown away yet. And everything new is always met with hostility - over time, all those who have ever known the happiness of straightening a greenhouse that has collapsed from snow will definitely implement such know-how.

7. Simple design

Agree, a removable roof for a greenhouse is only needed when it can be removed easily, in a maximum of 10 minutes. Therefore, let's take a closer look at the proposed design option - these are meter-long polycarbonate sheets that slide down. Height 2 meters, two vents at the ends and two doors. There are trusses on the roof every meter, and a special profile with grooves is attached to each of them. Polycarbonate is inserted into them, which can be moved down with a slight movement of the hand. There is also a special clamp on the side, which is used when the roof is closed so that it does not move out.

How to prevent a polycarbonate greenhouse from breaking under winter snowfalls and get an excellent harvest?

Don't try to solve the problem - just push it aside!

When leaving your dacha in the fall, remove the roof from the greenhouse in 10 minutes and forget about the greenhouse for the whole winter! No more traveling to shake off snow!

Reusable and quickly removable roof!

To prepare the greenhouse for winter, you only need 10 minutes: remove the clips securing the polycarbonate and slide the sheet (1 meter wide) down. The greenhouse will not break down in winter, and beneficial precipitation will fall onto the ground.

In the heat of summer, it’s easy to ventilate or remove the roof completely.

Tomatoes in a greenhouse do not get sick, since there are no drafts and no condensation forms. The fruits set without additional shaking thanks to air flows in the upper part of the greenhouse. The harvests are excellent.

-If you've been worried all fall about how to prevent the greenhouse from breaking down under winter snowfalls

— And in winter, they intensively threw snow into the greenhouse, at the same time checking whether the supports could withstand the weight of the snow

-And in the spring we were racking our brains on how to plant seedlings correctly, because the walls of ordinary greenhouses interfere with the free growth of plants

— And the summer, in the heat, they tried to save the tomatoes from overheating......

The ideal solution to all your problems and the dream of the most practical summer residents is a greenhouse with a removable roof.
