The best polycarbonate greenhouses for summer cottages in 2020

A good greenhouse is the key to a rich harvest.You can build a greenhouse yourself, but during the construction process you face such difficulties as the selection, purchase and delivery of material for the manufacture of the frame and covering of the structure, the selection of accessories for such elements as vents and doors, as well as fitting all parts to each other and assembly all this into a single whole. Exactly because of this reason more and more summer residents prefer not to build greenhouses on their own, but to choose ready-made options, designed by specialists, simplifying the processes of transportation and installation, as well as taking into account all the features of the Russian climate.

Criteria for choosing a good greenhouse

The purchase of a greenhouse is a solid investment, so it is worth approaching the selection process thoroughly. In order for a structure to serve for many years and not cause trouble, it must have a solid foundation, 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, there are thousands of greenhouse models from hundreds of different manufacturers on the market for goods for summer cottages and gardens. The following quality ratings are based on feedback from real customers. It included only the best manufacturers from Russia and foreign countries:

1. Volia is a Russian company headquartered in Dubna. The characteristics of the products of this trade group are most suitable for the climatic conditions of central Russia;
2. Trade House "Urozhai" - 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 better to buy, and will make changes to the drawings based on the individual needs of the buyer;
3. Factory of ready-made greenhouses "Osnova" - the company has many branches in Russia, which can be found by a resident of any large city. ZGT "Osnova" not only designs and manufactures greenhouses, but also delivers and assembles;
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 by transport companies of "Very Strong" products to the regions.

Choosing a greenhouse frame

The skeleton is a kind of skeleton that helps hold the entire structure.You should not save on materials, otherwise the greenhouse will not stand for a long time. The main materials, their pros and cons are shown in the summary table.

Materials of construction	pros	Minuses
Wood	Environmentally friendly, low cost	Sags, subject to decay
Aluminum	Lightness of material, ease of care	Does not withstand heavy loads, breaks down under the influence of strong wind
Plastic	Elegance, lightness, accessibility	Low strength
Steel	Ease of assembly, reliability, remains in its original form for a long time	High price

Summing up, we can say that inexpensive materials turn out to be such only at first glance: an aluminum or plastic structure will ultimately cost many times more expensive than steel. Constant repair work to replace the 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 cover: polycarbonate, film and glass. Each of the materials has its own advantages and disadvantages, which can be compared in a pivot table.

What to consider when choosing	Glass	Polycarbonate	Film
Strength	Resistant to snow and wind, but will not withstand hail	High, the thinner the polycarbonate, the higher the strength	Low: simple film will last 1-2 seasons
Mounting	The help of specialists will be required due to fragility and heavy weight	Depends on the greenhouse frame, can be simple or medium	Plain
Plant comfort	Heats up quickly, but also cools down quickly, colder than others	Provides proper temperature and humidity	Provides proper temperature and humidity
Sustainability	High	May release harmful substances when exposed to high temperatures	May release harmful substances when exposed to high temperatures
Main advantages	Resistant to abrasives and pesticides: the residues can be simply washed off with water, retain an attractive appearance for a long time, you can save on the frame due to the large weight of the glass	Low price, lightness of weight and installation, availability, maintains an ideal microclimate in the greenhouse, unpretentious maintenance	Low cost, easy operation
disadvantages	Cannot withstand hail and fight	If the greenhouse is not ventilated, on sunny days the temperature rises to 55 degrees Celsius, it can break under a thick layer of snow	The need to dismantle at the end of the summer season

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 greenhouse coating are very different from each other. Nevertheless, polycarbonate is the optimal coating for a summer cottage.

What polycarbonate is better to cover the greenhouse

There are several types of polycarbonate:

1. Cellular polycarbonate is the most widespread on the market for summer cottages, because it has a low cost and good thermal insulation properties, ideal for covering greenhouses. The most common sheet thickness is 4 mm, a 6 mm sheet will have special strength;
2. Monolithic polycarbonate - you can rarely find it on the store counter, although the quality of the material is much higher than that of its cellular counterpart. An almost transparent canvas transmits up to 90% of the sun's rays, has a higher strength, easy installation and high flexibility. The owner can choose what color of polycarbonate will decorate his greenhouse, an important advantage is the environmental friendliness of the material and safety for health;
3. Profiled polycarbonate is a novelty on the Russian market that has not yet received wide distribution. At a 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 cover has a wavy structure and should be used for greenhouse and greenhouse roofs.

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

The best arched polycarbonate greenhouses
