Which is better: a glass or polycarbonate greenhouse

Buildings made of glass were very popular for several decades.

However, now, it is increasingly being replaced by polycarbonate, the main advantages of which are:

  • The ability to transmit ultraviolet light without harm to plants;
  • Flexibility - polycarbonate can be bent easily and without harm to it, to give the desired shape. Therefore, it is much easier to assemble a greenhouse from it, especially if the material is of high quality;
  • Easy handling - if necessary, polycarbonate layers can be easily replaced with new ones, without the danger of damaging other parts;
  • Keeping warm - in early spring, polycarbonate buildings warm up much faster than glass ones, which is especially important for those who decide to grow greens. However, it is important to remember that it is not suitable for hot summer days, as there is a danger of simply burning the seedlings;
  • Resistance to large masses of snow - does not crack and does not leak at the joints, which allows you not to fear the destruction of the greenhouse during the period of prolonged winter snowfalls.

Some gardeners consider polycarbonate to be the ideal material, but others also note a number of disadvantages, which include too dim light and the danger of burning plants when the temperature rises outside.

At the same time, the advantages of glass are noted:

  • Durability - on average, glass serves up to fifty years without losing its presentation. At the same time, polycarbonate loses its transparency after a few years and needs to be replaced;
  • Protection from fungi, mold and harmful microbacteria, which provides a continuous structure, in contrast to the honeycomb structure of polycarbonate, due to the unimportant insulation of the edges;
  • Impervious to temperature fluctuations, does not deform;
  • Low cost - during construction it is not necessary to use new glass, what has already been used is also suitable;
  • Non-flammable - it does not melt from a rise in temperature and does not catch fire, unlike polycarbonate. The latter, although it is hard to catch fire, easily loses its shape with an increase in temperature;
  • It is harder, does not bend and retains its original shape;
  • Practical in relation to heating systems. When glazing, you can use absolutely any, since it is not as sensitive to temperature increases as plastic. This also makes it possible to mount a "warm floor" in a continuous glass greenhouse;
  • Perfectly transmits light, since it is much more transparent than polycarbonate and does not block it.

You can argue about the advantages and disadvantages of materials for a long time, but it is important to remember that during construction, you can also pay attention to the third option for solving the problem.

Combine both, covering the roof with polycarbonate, which will reduce the load on the snow mass and the glass side parts. This option is much more convenient and cheaper than a continuous covering of the frame with plastic.

When choosing, it is important to focus on the quality of the material, weather conditions, take into account what exactly will be grown. Only by answering these questions can you choose the most suitable option.

How to start building a glass greenhouse with your own hands: choosing a place

After the issues with the materials are resolved, it is recommended to devote at least time to choosing a place where to locate the building. The correct location is the key to a large and healthy harvest.

So, when choosing a place, it is important to consider whether it will be convenient to approach it, compare its future location with the wind rose, its position in relation to sunlight, and determine how convenient it will be to conduct electricity to it.

Other aspects that are recommended to look out for include:

  • The proximity of trees, this is especially important, as broken branches can pierce the material of the roof and walls and destroy the crop;
  • How large is the angle of inclination of the section under the structure, it is recommended to take this into account in order to reduce unnecessary loads;
  • Is the site not located in a place where the snow mass rolls down from the main building in winter or water flows down during summer and off-season showers;
  • Is it possible that the building will be in the likeness of a wind tunnel formed by the walls of buildings.

The selection of the right place for the future structure is an important stage of construction. It depends on the correctness of the choice how good the harvest will be and how much effort will have to be spent on caring for the structure and maintaining it in working order.

Laying the foundation and making the frame

The second stage, which is in no way inferior in importance to the choice of location, is the laying of the foundation. It is important to take into account that a glass greenhouse is quite heavy by weight and its pressure on the foundation is important to take into account.

In addition, when choosing a specific type of foundation, it is recommended to pay special attention to the soil, since it also depends on how stable the structure will be.

There are several types of foundations that are most suitable for such a structure:

  • Monolithic slab - suitable for building large greenhouses located on clay soils;
  • Monolithic tape, represented by bricks, blocks or solid concrete. It is used on non-porous soils with low rates of soil water occurrence;
  • Piles made of wood, metal, plastic or concrete - used for construction on clay soils that are not prone to rapid absorption of precipitation;
  • Poles represented by concrete, bricks or blocks are recommended for buildings on hard, resistant soils of lightweight structures.

No less varied is the choice of frame options for future construction. The most common are those indicated in the table.

Small houseIt is distinguished by the presence of straight side walls, the glazing of which is made to the very ground, which creates the most comfortable conditions for seedlings. In addition, this type of construction can withstand the loads of snow and rain as easily as possible, minimizing the risk of glass damage.
RoundedIt features a round shape and a convex or gabled roof. In the center is the space for the gardener to work. The special device of the transom provides high-quality ventilation that does not allow the air to stagnate. The only drawback is that it is quite difficult to build such a frame on your own.
DutchOutwardly, it resembles a little "house" type, but the walls in it are located at a slight slope
WallIt differs in the fact that one of the walls is adjacent to the main building, due to which heat is better retained inside the greenhouse

The optimal type of frame is considered to be a "house", which is distinguished by its simplicity of construction. Since the structure consists of flat components, it is not difficult to insert glass.

How glass is fastened in a greenhouse

After installing the frame, it's time to think about how to fix the glass in it. Usually one of the following methods is used:

  • Traditional - each piece of glass is laid on a special putty and then secured with small pins. Since the modern construction industry is constantly evolving, you can forget about window putty and pay attention to sealing, quickly hardening putty;
  • Grease-free - a more modern and better way of fixing glass. With it, the layers are simply inserted into special grooves with a cross section, which allows sealing without the use of putties.

Both methods are widely used and in the choice it is recommended to focus only on your own convenience and preferences.

Homemade double-glazed greenhouse and its advantages

Since double-glazed windows are now replacing ordinary window glass, it is not surprising that greenhouses made of the same material can be seen on garden plots. Since prices for building materials are constantly growing, not only new ones are used, but also used ones, which were used for glazing windows.

The main advantages of a double-glazed building include:

  • Neat and attractive appearance;
  • The ability to maintain the desired level of humidity;
  • High level of resistance to snow weight and wind blows;
  • Durability - double-glazed windows do not deform, do not lose transparency for a long time;
  • High-quality thermal insulation of the internal space;
  • Fire resistance - the components are not flammable;
  • Easy to repair components;
  • Simplicity of care;
  • Resistance to physical exertion and blows, if such material is accidentally touched, it will not crack or break;
  • Resistance to temperature fluctuations;
  • Ecological cleanliness;
  • They are an unsuitable breeding ground for fungi and pathogenic microorganisms that could harm plants.

Double-glazed windows are very durable, which is especially important for any structure. Unlike other materials, they are quite difficult to break even if desired.

Such a structure will faithfully serve for more than a dozen years and, with proper care, will allow you to collect a lot of crops.

The only drawback of such a structure is its cost. Buying all the materials can hit your wallet pretty hard. You can save a little by making a roof from a different material; polycarbonate is perfect for this.

Features of the design of a winter greenhouse made of glass

Despite the fact that all greenhouses seem to be exactly the same in their essence and principle of operation, this is not entirely true.

It is important to remember that winter structures have their own characteristics, which should not be forgotten when building:

  • Material - a winter greenhouse will only maintain sufficiently high temperatures if its walls and roof are made of glass. When the frame is covered with polycarbonate, only the installation of a powerful heating system can maintain stable high temperatures. And, of course, it cannot be covered with a film, this option is suitable only for summer buildings;
  • The obligatory presence of a heating system, without which the plants simply will not grow;
  • The base of the frame - it is recommended to pay special attention to iron and wood, as other materials may not withstand the weight of the glass with snow and will simply collapse;
  • Roof shape - Since there is a danger of a lot of snow falling in winter, it is important to tilt the roof so that it rolls off. If this is not done, the snow mass can press through the roof and fall on the crop;
  • The foundation must be solid concrete or brick, in no case should the winter version be installed simply on the ground, without installing the foundation;
  • Electricity - since the day at this time of the year is significantly shorter than the night, plants do not receive the required amount of light and it is recommended to support them with additional artificial lighting.

Winter ones are distinguished by a number of features that should not be forgotten. If you do not pay attention to them, there is a danger of wasting energy and ruining the harvest.

It is quite possible to make a glass greenhouse with your own hands. This will require some effort and money, but if you want to develop a greenhouse project and translate it into reality, every owner of the participant will be able to.
