Film for greenhouses "Svetlitsa" - the best solution in the arrangement of greenhouses
The most affordable and optimal option for wrapping the frame of the greenhouse is considered to be a film. It is inexpensive and easy to work with. When using film, gardeners do not mean ordinary, polyethylene material. We are talking about a modern film "Svetlitsa", produced by the company NPF "Shar", St. Petersburg.
This material has become an indispensable tool in the garden and vegetable garden. The film has established itself as a durable and durable product. In a greenhouse covered with "Svetlitsa", gardeners manage to harvest 20-30% more crops than in those where ordinary film or polycarbonate is used.

Film characteristics
"Svetlitsa" is a copolymer material that is particularly durable and resistant to mechanical and thermal influences. When comparing conventional film and copolymer material, the performance indicators will differ significantly:
- Strength. Ordinary film breaks easily - wind, hail, strong tension, accidental contact with sharp objects instantly break the material. That is why polyethylene needs to be changed every year. The copolymer material has three times the strength. Natural disasters and mechanical stress do not damage the surface.
- Frost resistance. The material "Svetlitsa" is able to withstand temperatures down to -80 °, which cannot be said about ordinary films.
- Hydrophilicity. This characteristic is very important in horticulture. The accumulated condensation should not accumulate in hot drops and fall on the plants. This does not happen if the greenhouse is covered with Svetlitsa material. Polyethylene does not possess this property.
- Small statics. The film accumulates static electricity one and a half times less than polyethylene.
- "Svetlitsa" "one and a half times more elastic. If you try to tear this tape, it is unlikely that you will succeed.
- The copolymer film retains heat better, the room temperature is about four degrees higher.
The technical characteristics of the film are far superior to polyethylene. That is why gardeners have long forgotten about the use of conventional film and prefer to stretch copolymer material onto the frame of the greenhouse. The assortment of the SPF "Shar" company includes films for both the southern and northern regions. They are called reflective and transparent.
When buying a film "Svetlitsa" always take into account the region of growing crops.
When using the former, an acceptable climate is maintained in the greenhouse in case of heat. This happens due to the reflection of ultraviolet radiation, the material transmits about 20% of infrared radiation. Transparent film is intended for northern regions, it transmits up to 95% of infrared radiation.
Advantages of the "Svetlitsa"
Based on the characteristics of the film, we can confidently state the advantages of the material. Gardeners like it because of its increased elasticity and resistance to temperature extremes. It is not at all necessary to remove the film for the winter, it will perfectly tolerate low temperatures, will not bend under the snow and will not crack.
The service life of the material is seven years, taking into account the location in low temperatures.
In other words, the gardener does not have to endlessly change the film.We can safely highlight another important advantage - condensation does not drip onto the plants from above. The accumulated moisture flows down the walls, and does not form into large drops, which then inevitably fall on the plants. This is an important plus. Gardeners using the Svetlitsa film all as one assert about the increased yield. The microclimate under the film is much more comfortable than that formed under ordinary polyethylene or polycarbonate. This increases the yield.
Gardeners love the material's strength and elasticity, which is retained at low temperatures. When shoveling snow from the greenhouse, do not be afraid that the film will crack and tear. In a strong wind (18m / s), the greenhouse will remain intact. After hurricanes, no one likes to walk around the garden and collect scraps of film. This will not happen with the copolymer "Svetlitsa". That is why gardeners liked this material; problems with it have not arisen for many years.
Film installation
The film is sold in rolls of various widths and lengths. The strips are easy to connect during installation. In the case of using the "Svetlitsa", there is no need to come up with a way of fixing the seams. The strips are overlapped without fasteners. That is, the material, when it comes into contact with each other, "grows together" so that air and water do not penetrate in the overlap areas. When dismantled, the seam diverges quite easily.
If you wish to secure the seams, you can use standard bonding methods.
But this is not necessary at all. The rest of the installation of a greenhouse with a covering material "Svetlitsa" is no different from what is used with polyethylene. The film "Svetlitsa" has become indispensable in the arrangement of the greenhouse. It meets all the requirements of gardeners and meets the conditions in which greenhouse plants are grown.
