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.

How to choose what to pay attention to

The basis of any greenhouse is a frame that must hold not only polycarbonate, but also snow. To prevent the structure from breaking, the following materials are used:

• – wood – environmentally friendly, low cost. Due to contact with wet soil, the lower part begins to rot and sag;
• – aluminum is an easily processed metal and is not exposed to moisture for a long time. The disadvantages include the ability to break in strong winds and snowfall;
• – steel is the most durable material that can last for many years. Cons: high cost, must be treated with anti-corrosion agents (powder paint, zinc coating).

Types of covering materials:

1. plastic film - easy to install, but only lasts for 1-2 seasons;
2. glass - more often used for industrial cultivation of crops due to its environmental friendliness, resistance to wind and snow. Cons: may break during hail and cause injury;
3. polycarbonate - combines the positive properties of glass and film.

An important factor is the shape of the greenhouse. Several designs are suitable for polycarbonate:

• – arched model – characterized by capacity, a minimum number of joints, and is resistant to wind. In winter, snow must be removed from the roof;
• – gable form – this type of greenhouse is difficult to install and takes up more space;
• – cone-shaped – ideal for growing tall plants (cucumbers, tomatoes).

When installing cone-shaped greenhouses, special attention should be paid to sealing the ridge.

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.

Manufacturer. Characteristics. Flaws.

Assembly instructions

Using a grinder, cut the profile to the required dimensions according to the drawing. The mounting posts are welded around the perimeter to the embedded posts. The usual distance between them is 1 meter.

Then the upper reinforcement is installed. The braces and cross beams are welded to stabilize the structure. When installing a pitched roof, two pipes are cut in the middle with a grinding machine and bent to the required angle at the intersection.

The ridge is cut to the required length and the pipes are welded together. The door frame is also made of pipe and hinges at one end. On the other hand, the window sash is made in the same way.

The main parts of the structure can be welded on a flat surface, after which the finished trusses are installed on the foundation.

Greenhouse installation

And now, you have purchased all the necessary materials, now the question arises, how to make a greenhouse? Where to begin?

Creating a foundation The basis of any structure is the foundation, and for a stationary greenhouse it is one of the main elements. If you used cement, you need to give it time to harden.

An ordinary construction knife for cutting polycarbonate sheets. It is worth noting that in order for the structure not to deform, the sheets must be fastened at least 1 - 1.2 meters.

Assemble the frame and secure it to the foundation.

Cover the frame of the future greenhouse with polycarbonate sheets. Fasten the sheets with an overlap of 6 - 10 cm or end-to-end using a special profile. To make the structure stronger and more durable, connections must be made on a supporting base.

If you cannot visit the site often enough to water on time, it is necessary to provide the possibility of automatic watering. You also need windows that open and close automatically to maintain the desired climate.

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).

Pros of using polycarbonate

Unlike glass greenhouses, polycarbonate has more advantages, such as:

Compared to glass, polycarbonate is much stronger. For example, snow in winter can cause glass to crack or even break, while polycarbonate is more resistant to weather conditions.

Less UV penetration means that plants grown in a polycarbonate greenhouse will suffer less burns than in a classic glass greenhouse.

Excellent thermal insulation; Compared to glass, it again retains heat better, since the polycarbonate material is two-layer.

It withstands temperature changes and maximum altitude well. Glass, on the other hand, can break.

When heated, it is a flexible material, making it quite easy to work with and allows for easy drilling. Polycarbonate is available in separate sheets of standard sizes, so the greenhouse can be covered with 3-4 sheets.

Compared to a glass greenhouse, polycarbonate diffuses the sun's rays, so plants do not get sunburned.

Last but not least is the price. A polycarbonate greenhouse will cost much less than a glass one.

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.

Cons of polycarbonate

But when choosing polycarbonate, you should not forget about the disadvantages of this material:

Polycarbonate is not durable. Constant exposure to sunlight makes the greenhouse more sensitive.

There are a lot of fakes, if you are unlucky enough to buy low-quality polycarbonate, you may have big problems due to its lack of strength. A standard good quality polycarbonate sheet weighs 10 kg; if the sheet weighs less, it may be a fake.

There may be problems with additional heating of the greenhouse. Avid gardeners who would like to extend the harvest year install additional heating in them.

The frame is the basis

In order for the structure to last for a long time, before choosing a greenhouse, you need to carefully evaluate its frame.

Material from which the frame is made

Today, the best material for greenhouses is an aluminum profile - it is environmentally friendly, durable, has high strength, does not corrode and is aesthetically pleasing. We offer a wide selection of greenhouses made of aluminum profiles. For more than 10 years, she has been creating comfort for clients on their sites. Don’t be lazy, go to the website www.teplici-lux.ru and choose a decent greenhouse for yourself.

For polycarbonate greenhouses, the frames are made of metal: pipes or profiles are used.

Advantages and disadvantages of metal pipe construction

When choosing this option, pay attention to its advantages:

1. High strength that does not require additional reinforcement.
2. Good stability regardless of installation method: on the foundation or on the ground.

The disadvantages include the high price and possible difficulties with installation.

Advantages and disadvantages of metal profile structures

The main advantages include:

1. Affordable price, which in no way affects the characteristics of the structure.
2. Ease of transportation and installation is ensured due to the compactness and lightness of the materials.

At the exhibition there is a sample of a greenhouse www.teplici-lux.ru made from the PROVEDAL aluminum profile.

However, it is necessary to take into account that there is also a significant drawback - mandatory reinforcement of the structure is required.

Dimensions of the greenhouse and individual elements

When determining the size of a greenhouse, the first thing to consider is its purpose and planned production volumes. Design work, even in the most simplified version, allows one to calculate the required amount of materials with sufficient accuracy.

The general rules for carrying out this type of activity are as follows:

• It is necessary to establish the length, width and height of this structure. This takes into account the area and configuration of the site and the convenience of working in the greenhouse.
• The angle of the roof slope is determined to ensure spontaneous sliding of snow.
• When determining the size of the doors, it should be taken into account that the person will carry tools and agricultural equipment during the work process. In addition to the entrance, a folding transom is provided in the wall for ventilation of the structure.
• The structure of the frame must be such that the joints between individual sheets of polycarbonate must fall on its elements. This approach allows us to significantly strengthen the structure.

Features of the package

The standard configuration of greenhouses has not only arcs and transverse connecting elements, but also end elements, vents, and doors. It is best to choose an option in which there are doors on both sides and side windows - this is convenient and very practical. In most cases, the side window is an addition to the main structure.

In addition, you should take care of one more nuance: the distance between the arcs. Reliability and strength depend on this indicator. So, for example, at a distance of 0.65 meters (reinforced version), the stability is much higher than at a distance of 1 meter.
