The use of a reinforced film for covering greenhouses

film not only gardeners, but also the owners of private houses on their plots suit different size and design structures that can be grouped under the general title "greenhouse."Without dwelling on the construction and choice of technology (described here) and the internal arrangement (eg, utilities), we consider only one, but a very important question.It was largely on the quality of natural light depends on the intensity of the shoot plantings and yields.

as clearcoats used a variety of materials - from a variety of types of films to glass.All depends on the material features hosts and other factors, such as frequency of use hothouse (only in the season or during the year).In recent years, increasingly touted reinforced film.But before we analyze the effectiveness of its use, should be to find out what criteria should be evaluated in general a specific material for such a "glazing".




What film should provide

  • protecting trees from the influence of external factors: wind, temperature changes (including frost), rain, fog, ultraviolet radiation.
  • Maintain a constant temperature, and at a level favorable for plant growth.
  • To increase humidity inside the "room."

From the name of the material - "reinforced" - implies that it has some reinforcing structure.And this is indeed the case.In one approach, such a film is a network having cells which are filled with polyethylene.But the thread may be different.Depending on the manufacturer for the manufacture of glass used, woven polyethylene, polypropylene fibers and the like.

All reinforced mesh cells differ in size and thickness as they are, and threads.Preferences for the term of operation to give any single mind can not, because all the "modifications" declared by the manufacturer service life of about 3 years.

best to apply a reinforced film, in which the cells are microscopic holes that give high-quality natural ventilation nestled space.This differs, for example, products of the Danish production.

advantages of reinforced films

  1. withstand heavy loads compared with conventional PVC.It is advisable to use, if the greenhouse is not versed in the winter in regions with heavy rainfall, in areas subject to increased exposure to wind.
  2. has good resistance to damage.People say that if there is a mechanical action on the material, causing it to rupture in a certain place, the cut on the "do not go", as this will prevent the filament reinforcement.Accordingly, the film can be "repaired", while laying on the PVC sense patch no.
  3. Can be used for several seasons.
  4. In the case of the Danish film can not take care of the daily room ventilation is not equipped for this purpose, "vents".

cost depends on where and at what technology produced product.In the domestic market are more common domestic, Korean and Danish film.

The cheapest samples can be bought at a price of 17 rubles / rm.Rolls of material having in its structure, light stabilization layer, sold 1 150 rubles (50 m²).

Based on the above, it turns out that the film is reinforced is much better suited to cover greenhouses than regular PVC.
