Give your plants a quality polycarbonate greenhouse
Polycarbonate greenhouses, covered with polyethylene foil or glass, which used to be an integral part of the colour of Czech gardens, are increasingly disappearing. Most Czech gardeners are switching to greenhouses made of modern materials, especially polycarbonate.
Types of polycarbonate surfaces
There are greenhouses with several types of polycarbonate surface, mostly hollow polycarbinenate. Its name comes from the internal structure of this modern material. These are two or more layers of transparent polycarbonate films, connected by a large number of connecting ribs, which create a large number of cavities inside the material. Boards with a protective layer against UV radiation on the outside and a special colourless coating on the inside, which reduces the surface tension of the material and facilitates drainage.
Cellular polycarbonate sheets must be at least 4 mm thick. The optimal parameter is 6mm – 8mm (in winter) or 10mm – such material successfully withstands load even during year-round use. This construction provides hollow polycarbonate with unique properties – excellent light and heat transfer, high durability, low weight and a much lower price than, for example, glass.
Comparison
Depending on the material from which the frame is made, all greenhouses can be divided into:
CONSTRUCTION:
Aluminium or galvanised sheet metal profiles
The advantages of aluminum neno sheet metal profiles are elegance, lightness, and easy care are stainless steel. But lightweight construction requires fastening to more stable foundations, and this is an additional cost. In addition, there are great risks that it will be destroyed by wind and snow. The thickness of the metal is usually equal to 0.5-0.8 mm; arches consist of many parts. Complex, time-consuming assembly due to many parts.
Steel – based on steel,
The heavy steel construction can withstand any weather, is easy to assemble and serves for a long time. The best and strongest greenhouses are made on the basis of galvanized steel steels, metal thickness 1-1.2 mm, they are stainless steel – hot-dip galvanized, and therefore a high-quality construction will protect the harvest forever. Honest manufacturers switched to production with steel structures.
What to pay attention to when choosing a galvanized steel frame greenhouse:
– Metal thickness – min 1 mm
– It is better to choose a structure using hot-dip galvanizing than painted. Hot-dip galvanizing guarantees protection against corrosion for many years.
However, a galvanized construction with powder coating is definitely the best option.
The buyer himself decides which surface properties are a priority, we offer a choice of various selected price categories.
COVERING:
Greenhouse and hotbed made of glass
Glass panes are easy to maintain, let in light and conscientiously heat the greenhouse. But the roofing also has enough minuses:
- high weight requires a reinforced structure,
- heat loss due to high thermal conductivity,
- does not have protection against ultraviolet rays,
- brittleness
- risk of injury from shards if broken (particularly high danger to children and pets),
- difficulty of replacing the boards.
Greenhouse and hotbed made of POLYCARBONATE
New technologies have also come to greenhouses. Polycarbonate, due to its improved properties, confidently occupies a leading position compared to glass or foil.
Hollow polycarbonate is currently the most popular material used for covering greenhouses, pool roofing. Thanks to the fact that this modern material is 6 times lighter and 200 times stronger than glass, polycarbonate greenhouses do not require a solid foundation and are therefore easily transportable.
However, compared to polyethylene greenhouses, they have much better thermal insulation and higher light transmission, which can reach up to 88%. In addition, they absorb UV radiation to a large extent and thus protect plant leaves from burns. You can leave a polycarbonate greenhouse in the garden all year round, as it can withstand temperatures from -40 ° C to +120 ° C.
Advantages of polycarbonate:
- special protective layer against UV radiation,
- lightness
- high durability, it is 200 times more durable than glass,
- low thermal conductivity, which prevents air from getting out of the greenhouse and has excellent light transmission,
- resistance to blows, now a soccer ball or hail will not damage your greenhouse,
- resistance to various weather conditions,
- Long service life
Greenhouse and hotbed made of FOIL
However, the cheapest material, which transmits sunlight quite well, has a number of drawbacks:
- fragility of the structure (the film can easily tear and destroy the crop in wind or hail),
- the need to change the foil every year,
- rapid soiling and complexity of cleaning the film,
- lack of UV protection,
- danger to children and animals (risk of suffocation).
