The best polycarbonate greenhouses for summer cottages in 2022

Expert selection:

Mini rating (updated in 2022)

What determines the choice of greenhouse?

The durability of a greenhouse depends on the materials used in its construction.

Let's look at the main design elements:

• frame;
• coating material.

Greenhouse shape

For a polycarbonate greenhouse, the most optimal designs will be the following shapes:

• arched shape;
• an equal-wall greenhouse with a gable roof shape;
• cone-shaped;
• spherical shape.

The arched shape of the greenhouse is classic for greenhouses; it is resistant to wind loads. It allows the fullest use of the internal space and has a minimum number of joints, but the frame must have significant strength, since snow can accumulate on the roof due to the arched shape.

Equal-wall greenhouses with a gable roof are more difficult to install. Such greenhouses have the greatest height in the central part and occupy a larger area than others. Cone-shaped greenhouses are best suited for tall plants. The shape of the roof allows snow to melt off easily, but problems may arise with the tightness of the roof ridge joint.

Spherical-shaped greenhouses appeared on the market relatively recently, but are quickly gaining popularity due to their advantages: lightness, mobility, better use of internal volume, illumination, high strength and resistance to various loads - wind, snow, etc., in addition, it is made of -due to its unusual shape, it is perceived as an art object and serves as a real decoration of the site.

An important condition when choosing a greenhouse will be the distance between the arcs - the smaller it is, the stronger the structure. You also need to pay attention to the number of windows, additional doors and the presence of seals. Greenhouses can be stationary or collapsible.

Collapsible ones can be installed on the site in the warm season and deal with the onset of cold weather. Stationary ones do not provide for the possibility of disassembly and re-installation. They can be equipped with a heating system that maintains the required temperature during the cold season.

Coating material

The material used to cover the greenhouse can be different:

• polyethylene film;
• glass;
• polycarbonate

Polyethylene film is the simplest and cheapest coating material. It allows you to create optimal microclimatic conditions in the greenhouse, but along with advantages, it also has disadvantages - the maximum service life of plastic film is 2 seasons, and as a result of heating by sunlight, substances harmful to health are released.

Glass coating is the most environmentally friendly material and has long been used in the construction of greenhouses. It is resistant to heat from sunlight, wind and snow, but there are also disadvantages - fragility, glass can break and cause serious injuries.

Polycarbonate combines the best properties of polyethylene film and glass coating, but the strength of such a coating depends on the shape of the greenhouse and the design of the frame. To protect against ultraviolet radiation, polycarbonate must have an additional layer.

Only transparent polycarbonate can transmit the required amount of sunlight.

The thickness of polycarbonate should be no less than 4 mm and no more than 10 mm. If the thickness is greater, the coating will not transmit sunlight well. The ability to retain heat is affected by the type of coating. It can be monolithic, cellular or profiled.

It is preferable to choose cellular or profiled polycarbonate - it weighs less and has lower thermal conductivity. Profiled polycarbonate due to its structure has greater strength. It is better suited for constructing a durable roof.

It is not recommended to choose polycarbonate with a density less than 0.65 kg/m2, polycarbonate made using recycled raw materials and having a warranty of less than 10 years. This material will turn yellow and crack.

Frame material

The strength of the structure mainly depends on the choice of frame. It must withstand the load from the coating itself and from adhering snow that can accumulate on the greenhouse.

The wooden frame is traditional. It has a low cost and is an environmentally friendly material, but wood also has a number of disadvantages - it is susceptible to rotting. Over time, such a frame will certainly sag.

The aluminum frame is little susceptible to corrosion, is light and easy to process, but under the influence of significant loads arising from stuck snow or strong winds, such a frame can lose shape or collapse.

The steel frame is the most durable and reliable. To protect against corrosion, thermoplastic coating of parts and galvanization of parts are used. The advantages of such a frame also include ease of assembly. Parts of the steel frame can be made from pipes, channels or angles.

What else needs to be considered

And finally, we’ll outline a few more points that need to be taken into account. So, a very important aspect is the shape of the greenhouse. This is especially important for regions where there is heavy snowfall in winter. Due to the heavy snow load, polycarbonate, and even the frame of the greenhouse, can easily break.

The traditional arched model of polycarbonate construction provides a lot of free space inside, but due to its fairly gentle slope, it requires regular cleaning of the roof in winter. The exception is very durable, reinforced greenhouses. An arched model, even the simplest one, is very wind-resistant.

Equal-wall structures with gable roofs also provide a lot of free space inside and can be very high. But they are usually difficult to install. As for the snow, it does not linger on such roofs, and this is already a big plus.

The third option is conical droplet greenhouses. They are optimal for those who grow tall plants. The snow comes off them without much difficulty on their own. But in most cases, this option requires additional sealing of the ridge part.

What else you need to look at:

• the distance between the arcs - the smaller it is, the stronger the greenhouse roof;
• presence of seals included;
• how many doors and windows are there;
• completeness of the set.

Technical characteristics and equipment of the greenhouse

has been operating on the market since the early 2000s and provides services for:

• design of greenhouse structures;
• their production;
• installation.

All of the company’s products are of high quality, undergo multi-level control, and the models have a unique design, which sets this manufacturer apart from many others on the market. All greenhouses have a reliable frame, for the cladding of which materials from proven and reliable suppliers are used, while the appearance of the greenhouse remains attractive.

Models of greenhouse structures differ in their design features and are selected depending on the needs of the customer, however, all models have:

• the base is a hot-dip galvanized steel profile, which helps protect the building frame from corrosion;
• The coating uses such a modern material as polycarbonate, which makes the structure durable, but at the same time lightweight, due to the fact that the thickness of the sheets is no more than 4 mm. The company has its own production of this material;
• the structures do not need to be dismantled for the winter;
• service life reaches 30 years.

Each greenhouse structure requires the installation of irrigation and ventilation systems, as well as heating. Due to the fact that Glass House provides a full production cycle of greenhouse structures, the company can control quality and set reasonable prices.

Did you know? In Iceland, it is not uncommon to find greenhouses next to a geyser - the inhabitants of this country effectively use the heat and hot water of natural sources for heating.

Advantages

The use of modern technologies, which are constantly changing and updated, makes it possible to produce increasingly high-quality products with an improved set of consumer characteristics.

• So, the advantages of the latest models include:
• individual approach at the design stage of structures: the ability to create unique rooms with internal partitions dividing the greenhouse into autonomous parts, organizing departments for storing equipment;
• the facilities can be used year-round;
• original fasteners for polycarbonate sheets, thanks to the use of which, structures acquire strength and resistance to weather disasters;
• high quality materials, the production of which the company controls at all stages - 1.5 mm steel and polycarbonate with two-component protection against ultraviolet radiation;
• there is a D-shaped, additional seal that allows you to create a microclimate inside the greenhouse;
• lightweight design of ventilation windows;
• zinc coating of steel structural elements;
• the high height of greenhouses, which allows a person to feel comfortable indoors, and also makes it possible to grow tall varieties of vegetables, etc.

Flaws

• The disadvantages include:
• the weight of the structure, due to the galvanized steel frame, can be impressive;
• the need to create a strong foundation;
• In the basic configuration of many models there is only 1 doorway.

Manufacturers rating

When choosing the best greenhouse, it is important to pay attention to the manufacturer. It is better to buy products from trusted brands that are responsible for quality. We have prepared a mini-rating.

Criteria for choosing a good greenhouse

Purchasing a greenhouse is a significant investment, so you should approach the selection process thoroughly. In order for a structure to serve for many years and not cause trouble, it must have a strong base, frame and coating, and provide effective protection of structural elements from environmental influences, such as moisture and ultraviolet radiation.

Which company is better to choose a ready-made greenhouse?

Today, the market for gardening and gardening products offers thousands of greenhouse models from hundreds of different manufacturers. The following rating of quality products is based on reviews from real customers. It includes only the best manufacturers from Russia and foreign countries:

1. Volya is a Russian company with headquarters in the city of Dubna. The characteristics of the products of this trade group are most suitable for the climatic conditions of central Russia;
2. Trading House "Urozhay" - since 2004, the company has grown greatly and has more than 200 retail outlets in the Russian Federation. Competent employees will tell you which greenhouse is best to buy and make changes to the drawings based on the individual needs of the buyer;
3. Plant of ready-made greenhouses "Osnova" - the company has many branches in Russia, which a resident of any large city can find. ZGT "Osnova" not only designs and manufactures greenhouses, but also delivers and assembles them;
4. LLC “OTT” - greenhouses of the “Very Krepko” brand. On the market since 2007. The company has its own production. Provides services for the delivery and assembly of its own products in Moscow and the Moscow region, assists in organizing the delivery of “Very Krepko” products to the regions by transport companies.

Choosing a greenhouse frame

The frame is a kind of skeleton that helps hold the entire structure together. You should not skimp on materials, otherwise the greenhouse will not last long. The main materials, their pros and cons are given in the summary table.

To summarize, we can say that inexpensive materials turn out to be so only at first glance: an aluminum or plastic structure will ultimately cost many times more than a steel one. Constant repair work to replace failed elements will be needed every season, which is unlikely to benefit the family budget.

In addition to the material of the frame arches, you need to look at the number of arches: the more there are, the higher the rigidity of the structure and, accordingly, the service life of the structure.

Greenhouse cover: polycarbonate or glass?

There are 3 main types of greenhouse covering: polycarbonate, film and glass. Each of the materials has its own advantages and disadvantages, which can be compared in the summary table.

Polycarbonate is often positioned as a budget analogue of glass, but in fact this statement is very far from the truth: the properties of all materials typical for covering greenhouses are very different from each other. Nevertheless, polycarbonate is the optimal coating for a country greenhouse.

Which polycarbonate is best to cover a greenhouse?

There are several types of polycarbonate:

1. Cellular polycarbonate is the most common on the market for summer cottage goods, because it has low cost and good thermal insulation properties, ideal for covering greenhouses. The most common sheet thickness is 4 mm; a sheet 6 mm thick will have special strength;
2. Monolithic polycarbonate - you can rarely find it on a store counter, although the quality of the material is much higher than that of its cellular counterpart. The almost transparent fabric transmits up to 90% of sunlight, has higher strength, easy installation and high flexibility. The owner can choose what color of polycarbonate will decorate his greenhouse; an important advantage is that the material is environmentally friendly and safe for health;
3. Profiled polycarbonate is a new product on the Russian market that has not yet received wide distribution. In terms of price, its sheet will be close to the cost of cellular polycarbonate, but in terms of density, the indicators are close to monolithic. This type of greenhouse covering has a wavy structure and should be used for the roofs of greenhouses and greenhouses.

To summarize, we can say that the answer to the question of whether to choose monolithic or cellular polycarbonate for covering a greenhouse depends solely on the financial capabilities of the buyer. If funds allow, it is better to opt for a monolithic coating.

"Dubrava" (from Glass House)

This type of greenhouse is more aimed at professional gardeners than at the average owners of summer cottages. The width of the structure is as much as 4 meters, while the standard for a summer cottage is 3. The length can be chosen to your liking, but the minimum is also 4 meters. Despite their large volume, greenhouses of this type are quite compact and do not look overly bulky. The height of the building is as much as 2.8 meters, and there are triangular windows on the roof for ventilation.

Additional ties are built into the frame - they not only give it rigidity, but can also help install additional ventilation, heating elements or lighting wiring. The frame can withstand up to 180 kg of snow per 1 square meter, provided it is even covered with cellular polycarbonate.

The average price for a 4x4 structure is 47,000 rubles.

Pros:

• compactness
• ability to plant very tall plants
• strength
• galvanized corners, handles and doors
• 30 year manufacturer's warranty (applies to frame)

Minuses:

• price

The best cone-shaped greenhouses

Cone-shaped greenhouses boast the maximum height. In some models, the ceiling is at a level of 2.5 m. There is no need to worry about the integrity of the polycarbonate in winter, since the snow mass easily slides off along the gable structure. Here are the best samples for summer residents.

Orange Droplet

Rating: 4.9

The gable greenhouse Orange Droplet is available in two versions. Domestic summer residents are offered two width options (2.4 and 3 m). Thanks to the high arch, it is convenient to grow tomatoes and melons in the shelter structure. Experts appreciated the presence of 8 stringers, which give the frame increased strength. It is worth noting the fastening of polycarbonate using bolts and thermal washers. The model is equipped with two doors and two windows. For its strength and practicality, “citrus” becomes the winner of our rating.

Users note the beautiful appearance and simplicity of design. Summer residents encounter minor difficulties only during the assembly process; additional sealing of the doors and ridge is also required.

Advantages

• strength and reliability;
• light snow melting;
• high-quality fixation of polycarbonate;
• galvanized profile.

Flaws

• insufficient sealing of the ridge and doors.

Kremlin Arrow

Rating: 4.8

The Kremlin Strelka greenhouse demonstrates good stability. The frame is made of a 20x20x1 mm profile pipe, which is coated with a layer of zinc. The model boasts a high arch (2.45 m), which will be important when growing cucumbers or tomatoes. But only one width is offered (2.7 m), this will be enough to arrange 2-3 beds. The maximum snow load is limited to 295 kg/sq.m. m. The structure has two doors and two windows. It is possible to install an automatic system for opening windows or a drip irrigation device.

Users speak flatteringly about the strength of the structure and long service life. The disadvantages include leakage and complex assembly. The model takes second place in our rating.

Advantages

• original design;
• high strength;
• durability;
• 5 year warranty.

Flaws

• many cracks and gaps;
• complex assembly.

Dachnaya-Strelka

Rating: 4.7

Another tall greenhouse made it into our rating. The Dachnaya-Strelka model has a height of 2.4 m and a unique pointed shape. With a similar length with other forms of greenhouses, it is possible to save up to 15% of the usable area. Experts liked the 3 m wide modification, which looks optimal for summer residents. The very durable frame is designed for a maximum snow load of 360 kg/sq.m. m. To install the greenhouse, no foundation is required; the structure is securely held on the ground using T-shaped ends. The compact dimensions of the disassembled frame allow the product to be transported in the trunk of a car.

The greenhouse failed to surpass the leaders in the rating due to its thin profile (0.9 mm), large number of connecting elements and lengthy installation (more than 12 hours).

Advantages

• unique pointed design;
• practicality;
• compactness of the frame;
• good ventilation.

Flaws

• thin profile;
• long installation.

Which polycarbonate greenhouse is better to choose?

Most summer residents think about installing a greenhouse immediately after purchasing land. However, not everyone can make a choice among all the variety. Cost, advantages, disadvantages, shape, coating and much more can vary greatly. That is why it is necessary to answer the following questions:

1. For what purposes? For business and help on the farm - large greenhouses, for additional cultivation of several types of vegetables - small ones. Year-round use - stationary, temporary - collapsible.
2. Which shape is best suited to natural conditions? The more snow, the steeper the slope.
3. Location? How much light, snow and wind will affect the structure? For harsh conditions, it is better to choose reinforced types.
4. Frame material? Wooden (constant care, low cost, fragility), plastic (durable, does not rot, low weight, poor thermal conductivity), aluminum (lightweight, rust-resistant, high cost), steel (durability, withstands heavy loads).

Choosing a polycarbonate greenhouse comes down to determining the shape, size and purpose of use. Only after determining the type of frame can you move on to choosing polycarbonate. The optimal thickness should be from 4 to 6 mm (7 mm for the roof).

Buy or make it yourself?

If doing something yourself is not for you, then, of course, it is better to buy a factory version; ready-made greenhouses are widely available for sale.

But any gardener will tell you that, as a rule, store-bought greenhouses are not durable enough. The structure should be further strengthened and placed on a good foundation.

When constructing a greenhouse independently, each gardener tries to ensure a high margin of safety.
