Reinforced film, reinforced tarpaulin and other types of covering awnings
The process of growing vegetables and berries can be divided into two stages: the construction of a greenhouse and the care of plants during their growth. Whether it will be possible to eat spring strawberries, and whether crispy cucumbers will appear on the table – largely depends on how and from what material the greenhouse will be built. The reinforced covering film, reinforced awning or special tarpaulin material used by gardeners create the most comfortable conditions for greenhouse plants.
Main characteristics of reinforced film
For a long time, polyethylene film was the only covering material for greenhouses. It met many requirements, but after one year of use, it became cloudy, and it transmitted light much worse. And the integrity of the canvas was often impossible to preserve during one season, it was easily damaged even with minor mechanical influences.
The reinforcing film for greenhouses that appeared on the market has practically replaced ordinary polyethylene. It has not lost any technical characteristics of this material, and it eliminates the main disadvantages of conventional polyethylene.
The reinforced canvas is a frame in the form of a grid, on which a polyethylene film is deposited on both sides. It is the presence of a dense mesh that allows the use of this material as a reliable covering coating and gives it a number of significant positive characteristics. Advantages of reinforced film:
- it is resistant to stretching, withstands significant mechanical damage;
- it has hydro- and vapor-insulating properties;
- withstands significant temperature fluctuations (from -30 to 90 ° C);
- durable in use (5 years or more).
This material is UV-resistant, withstands difficult weather conditions characterized by strong, up to heavy, wind, precipitation in the form of rain and hail.
Reinforced film, reinforced PE and membrane: properties of materials
Several types of reinforced film are produced. They differ both in the composition and size of the frame weaving, and the quality of the deposited polyethylene layers. The frame is made by interweaving threads that are created from the following materials:
- polyethylene (PE);
The thickness of the threads is different, which affects the strength and weight of the reinforced film. The cells may also vary in size. The film with large elements is more light-conducting, small dimensions enhance the strength of the covering material. In horticulture, a film is mainly used, having a cell size of 1.5 x 1.5 cm. This format provides optimal comfortable conditions for plants in greenhouses and greenhouses.
The films deposited on the frame differ in thickness, density and additives that improve the functional characteristics of the material. Additives provide the following properties of greenhouse films:
There are also membrane films, i.e. having microscopic holes in each cell through which air penetrates into the greenhouse – the so-called “breathing” films.
The form of release of reinforced film is rolled. The length of standard bundles is 10, 25 and 50 m. Sometimes there are rolls with a length of 100 m. The width of the film can be 2, 3, 4 or 6 m. When winding into a roll for ease of transportation, a wide fabric is folded: 3-4-meter – in half, the height of the bundles is obtained, respectively, 1.5 or 2 m; a 6-meter film is folded three times, as a result of which the height of the roll reaches 2 m. The canvases are hermetically packed, there must be a sheet with the characteristics of the goods inside.
Useful advice! When buying a roll of reinforced film, it is necessary to pay attention to the integrity of the packaging. If it is damaged, there is a high probability that there are defects on the material itself.
What can be reinforced with reinforcing film
The field of application of reinforced film is extensive. It is used wherever there is a need to build temporary premises, to shelter a structure, materials, objects, openings or plants from precipitation, moisture penetration, winds, low or high temperature. The main areas where reinforced film is used:
The active use of reinforced film in various fields of production and everyday life is facilitated by its elasticity, flexibility and light weight. It is not difficult to fix, dismantle and transport this material, complex and expensive tools are not needed to work with the film, special skills and abilities are not required.
What you need to know when choosing reinforced film for greenhouses
Before covering the greenhouse with a film, it is necessary to carefully calculate the dimensions of the covering cloth. It is necessary to calculate the turns, bends, taking into account the features of the frame structure. The reinforced film does not stretch, it will not be possible to stretch it even by 1-2 cm.
Special attention should be paid to the color. In order to create optimal conditions for plants, it is better to choose a white film. It retains sunlight least of all (light transmittance is 85%). If we take into account that reinforcement already significantly reduces this indicator, then using a green or blue film, you need to be prepared to reduce the illumination by another 5-7%. It is possible to purchase a color coating only if the types of crops for which such conditions are acceptable are planted in greenhouses.
For light-loving plants, it is necessary to choose a film with large cells of 1,5×1,5 or 2×2 cm.
A significant indicator is density. The strength of the material, durability of use and price depend on it. Traditionally, a material from 120 to 200 microns is chosen for greenhouses.
Useful advice! When purchasing reinforced film for greenhouses, do not rely only on the information (regarding density) placed in the product card of an online store or heard from a sales consultant. Be sure to require a certificate of quality of the product, where the exact data will be indicated. Visually and by touch, it is impossible to determine the density of the reinforced film, and this is often used by unscrupulous sellers.
The main characteristics to pay attention to when buying reinforced film:
- cell sizes;
- the presence of additives that enhance the consumer qualities of the film (hydrophilic, light-stabilizing, antistatic).
Reinforced film of 200 microns is often preferred. It belongs to the middle price segment, withstands significant mechanical loads, it is easy to work with. However, it is possible to purchase a reinforced film of 400 microns for the greenhouse. The price of such a material is slightly higher – by 3-4% relative to the cost of a film with a density of 200 microns.
If you cut out blanks from the fabric, glue them hot (using a soldering iron or a blowtorch) or cold, using adhesive compositions, you will get a cover for a greenhouse made of reinforced film 400 microns, which is convenient to put on the frame at the beginning of the season and remove at the end of it. You will not have to waste time on laying, fixing the canvas, there will be no risk of damaging it during fixing.
Reinforced film for greenhouses: consumer reviews and practical advice
Before installing the greenhouse, it would be useful to get acquainted with the opinions of those who have already used the film. No instruction takes into account all the subtleties and nuances that arise in the course of practical application.
“Leno film, 170 microns. This year I covered it for the second time. It’s fine, the light didn’t get any worse. My greenhouse is rectangular, there have always been problems with sagging canvas. Not so with this one: as fixed, and lies – no cavities.”
“A film with a rigid mesh, perfect. However, I had to fix the frame. The straight lines were cut off, and the curvature of the nailed rails immediately began to appear. But now I’m happy myself: the greenhouse is great. The grid refracts the sun’s rays, and inside the heat is not burning, but soft, moderate. While cucumbers, lettuce, radishes are developing normally. I didn’t spend my money in vain”
Nikolay Fokin, Yaroslavl
“I have heard the opinion that after a year of use, the reinforced mesh remains intact, and the film crumbles. Nothing has been damaged in two seasons, and it can’t happen unless the net is holed. I am satisfied with the state of the material, I am sure that I will use this film for the third season (and maybe more).”
Kristina Silina, Belgorod
In some reviews, users give advice that is worth listening to.
“I have a reinforced film of 200 microns on my greenhouse. It’s strong, it hasn’t torn anywhere in two years. The greenhouse is large, almost 30 squares. I also prepared scotch tape to patch it up, but I didn’t need it. However, he made a mistake himself. The frame is made of wood, and the film was nailed with a furniture stapler. Staples every one and a half centimeters. When I took them off, I made holes. This is in the first year of application. And this season I put a tape, which is used to pack boxes with heavy equipment, and punched a film through it. It’s more reliable, and I won’t make holes when I shoot. Or you can just put a film of dense polyethylene.”
The main drawbacks indicated in individual reviews mainly relate to the short duration of use.
“This reinforced film definitely doesn’t cost that much money. When I pulled on the polyethylene, I at least knew that it was for a year. And here they promised at least 3 seasons. After the first one, I already want to throw it away! Full of holes, dirty.”
Covering material for beds: a good harvest without unnecessary hassle
Varieties, recommendations for selection for different types of soil and plants. Practical use and application. Tips for choosing brands. Examples of operation.
“I didn’t like the reinforced film. In cloudy weather, the greenhouse is generally gray. And it’s not durable at all. There was a strong wind, twigs were flying, still without leaves, because it was early spring. We often have dry winds at this time of year. Full of holes. I can’t say that the cells are really empty, but there are a lot of punctures. The density is not the largest – 120 microns, but I expected the best. I don’t know what will happen before the end of the season. Disappointed.”
Opinions, of course, are different, but mostly positive content. Based on the reviews (from the experience of practical application), it can be concluded that with proper use, i.e. taking into account the characteristics of this material, the reinforced film still confirms the declared qualities and a guaranteed service life of 3-5 years.
Reinforced film in industry: the purpose of construction covering awnings
Another fairly wide scope of application of reinforced film is construction. Having started an object from scratch, it is almost impossible to complete it during the spring and summer period. Stored materials, uncovered premises need protection from autumn precipitation and winter cold. And this function is performed by construction awnings.
If there is a need to cover a small amount of building materials or a small room, you can purchase a film and make an awning yourself. The film should be bought with a density of 120 microns. If the awning will be used as a shelter for a short time, the film material can simply be pressed with heavy objects, but always with a smooth surface so as not to damage the polyethylene layer. When covering building materials, the bottom of the awning is easy to pull off with vinyl packing tape.
It is convenient to use construction awnings with grommets. Ready-made versions are always available with holes into which a rope or rope is easily threaded. Grommets can be installed independently by buying them in a specialized store. And if the awning is small and the eyelets need small, they can be purchased in the department of the shopping center, where sewing accessories are sold.
When choosing a construction awning, it is necessary to consider the following factors:
- intensity and duration of use;
- what weather conditions will affect the material;
- whether it is necessary to have fixing elements.
Based on the above factors, the density and dimensions of the material are selected.
A balanced approach to the choice will allow you to save money as much as possible and get the expected result.
Prices of reinforced films and manufacturers of the material
The retail chain offers reinforced film of imported and domestic production. The main suppliers of the film to the Russian market are Korea and China. The assortment is large, the material has various technical characteristics. Korean products are distinguished by high quality and appropriate price. Leno film is particularly popular. The material has different densities, polyethylene films are available both with and without various additives.
Among the Chinese products there is a reinforced film for greenhouses, the price of which is much lower than domestic analogues. Naturally, the material is of low quality. But the product is available to the consumer and therefore in demand.
Among domestic manufacturers, it is worth noting the Zagorsky Experimental Plastics Plant. The products are distinguished by a high level of quality. The frame thread is made of HDPE monofilament, durable. Films with additives that protect against the damaging effects of ultraviolet light are excellent for covering greenhouses. The plant produces canvases of various widths, including wide–format ones – 6 m. The products are protected from counterfeiting by a special type of marking – red threads.
The Stren film, which is produced by the Novopolymer TD LLC near Moscow, is also competitive. The material is durable, the reinforcing frame is made of polypropylene. Polyethylene layers have enhanced antistatic and light-resistant properties. The plant produces films with different cell sizes, which makes it possible to choose the optimal light transmission capacity.
The price of the reinforcing film largely depends on the density of the material. The larger it is, the higher the cost. Usually the price of this product is indicated per roll, less often – per running meter. In some cases, the price of reinforced film per m2 is negotiated.
Let’s take the prices indicated by trading companies for comparison. Reinforced film STRONG 120/2/25, cost – 26 rubles./ pog. m. Another type of fabric of Russian production: LLC “Liantrade”, reinforced film 200 microns, price – 53 rubles per m2.
Comparing prices, we can conclude that an increase in density by 80 g / m2 increases the price almost threefold. The cost of Korean-made analogues is 3-7% higher. Products manufactured in China and belonging to the economy class have a price 10-15% lower than the cost of domestic film with the same characteristics.
Useful advice! When purchasing reinforced film from any manufacturer, read the information about the product on the package. If there is no data, the product is not certified, and it is better to refuse this.
Tarpaulin fabric manufacturing technology
Relatively recently, a new type of covering material has appeared – tarpaulin. The word “tarpaulin” is translated from English as “tarpaulin”. It is made of polyethylene. The production process resembles the fabric manufacturing technology. Threads are intertwined, only not natural, but made of fused polypropylene. The threads make up a dense base, which is laminated with opaque polyethylene on both sides. The result is a material that in many ways exceeds the performance characteristics of tarpaulins and polyethylene used for shelter. This is an imported material, it is produced in Turkey, China, Korea, Poland and other countries. The price of tarpaulin is significantly lower than the cost of domestic covering materials.
The fabric has a pleasant blue or green color and has a number of high quality characteristics:
- lightweight, much lighter than tarpaulin;
- hydro- and vapor-proof;
- uv resistant;
- it has a low cost.
Initially, tarpaulin was used during road works. But almost immediately, the scope of its application expanded significantly: awnings began to be made from fabric. To date, there is no decent alternative and competition for this covering material.
Tarpaulin construction awnings: application without restrictions
The main qualities of this covering material make its use possible for various industrial, commercial and household purposes.
Tarpaulin has different densities. The minimum is 50 g/m2. Sugar bags are made from such fabric. Tarpaulin is used for the manufacture of awnings, the density of which is 65 g / m2 and higher.
The elasticity of the material allows you to cover objects of various configurations. The awning can be installed on the frame – an excellent temporary shelter will appear. If you connect several awnings, you will get a large canvas, with which you can equip a temporary large storage room. Tarpaulin canopy in construction is often used to create canopies, as well as to protect cargo materials during transportation.
Useful advice! As a canvas for the shelter of building materials, you should not choose tarpaulin, which has a density of less than 120 g / m2. Friction on a hard surface is inevitable in this case, and this can significantly shorten the service life of the awning.
The edges of tarpaulin awnings are always additionally reinforced by means of a polypropylene tape soldered inside. Grommets are inserted into the dense part of the awning (along the edge) at a distance of 1 m from each other. The extreme, angular grommets, which account for the maximum load, have additional plastic inserts.
The sizes of construction awnings can be very different. With small parameters, a low-density fabric is most often used. For example, a 2×3 m construction awning is made of a material whose density is 65-100 g/m2. It is usually produced without grommets and has a budget price. This is a popular shelter option for a short time. In addition to its direct purpose, the awning can be used in everyday life, during hiking, fishing, where it will serve as a tent or canopy.
With a size of 4 ×5 m, the construction awning already has grommets and is made of denser fabric (from 75 g/m2 and above). Although there are also economy options with a thin fabric. With a significant canvas size (100 m2 or more), reinforced film is used, the density of which starts from 170 g / m2.
Tarpaulin tent: positive and negative reviews
The versatility of tarpaulin awnings contributed to the appearance of a significant number of reviews. The quality, cost, and appearance are evaluated. As for the price, everyone has the right to choose here. Almost everyone evaluates the appearance as visually pleasing, aesthetic. There are different opinions on quality issues.
“From the point of view of water-repellent properties, such an awning is not bad. If well fixed, no dirt will penetrate. But I will argue about the strength. It doesn’t tear, but it’s easy to make a hole. I accidentally, without even exerting force, pierced the tent with a spatula. Of course, the defect was quickly eliminated, the patch was applied, but there is a fact of damage.”
Sergey Serenky, Maykop
“It seems that the grommets are held on nothing. On the first trip, two escaped. And most importantly – you can’t replace them with the same ones, you need larger ones. And I haven’t even met such people. There’s nothing to replace it with, I’m starting to get used to the holes. Maybe someone can tell me where to look?”
“An excellent awning, lightweight, durable, I use it myself, and I give it to everyone who asks. I chose dense, 180 microns. I was looking for grommets not made of plastic, but metal. Two of them have already been lost. The problem is small, it covers everything with the same quality, it keeps well, but, probably, the marriage was allowed when installing these rings. There was even a thought of returning the goods.”
Oleg Steiko, Perm
Poorly inserted grommets are a problem that is quite common in reviews. The main mass of opinions is positive.
“Light, I’m the only one coping with the size of 5×8 m. I use it for six months, there are no defects anywhere yet. I heard that you need to keep less in the sun, I take it off and fold it when you don’t need it.”
Evgeny Simonenko, Yekaterinburg
“When they made such a thin roof over my unfinished house, I was skeptical. But the builders were confident in the correctness of their actions, and I just watched in silence. Yes, they also joined together the blue awnings, made one of the two, ring in ring. At first, I resorted to checking after every rain. Even these torpoline awnings withstood the snow. Now I joke that I want to live under this blue sky.
Elena Postnikova, Yelets.
There are few contradictory reviews about tarpaulin. As a disadvantage, weak grommets dominate. As a virtue, users highlight the lightness, variety of sizes, price and reliability of protection from precipitation.
Reinforcing film: additional information for demanding buyers
Sometimes it is not easy to understand the quality of the goods. You get convincing information from the seller, you purchase a product, and it breaks, breaks, fails much earlier than the warranty period expires.
When buying reinforced film for greenhouses, the pitfall may be the use of secondary raw materials for the manufacture of not primary, but secondary raw materials. How can I find out? It is necessary to understand this issue yourself: no sales manager will share such information, even if he owns it. Do not be tempted by a cheap product if it is not marked on it that this is an economy offer. Carefully read the information about the film.
Be sure to read the information about the manufacturer (address and phone numbers), about the size of the product, technical characteristics, including a description of the composition, density and other characteristics, taking into account additives. If, according to the information, it was not possible to get a complete picture of the product, it is most likely not certified, therefore, you can forget about quality guarantees.
For those who plan to buy an awning from tarpaulin, it will be useful to have the following information. When cutting fabric for the manufacture of an awning, two technologies are used, more precisely, two dimensions are taken into account. The first option is when the final size is official, i.e. if the parameters of the finished product are specified. Such awnings are sold under the brand name “Tarpix”.
The second type of designation of official dimensions is by the cutting of the canvas, i.e. the size of the blanks is indicated on the awning. Naturally, the canvas bends, part goes to the seams. These are Tarpaulin awnings. If you bought a material with dimensions of 3×4 m, and it turned out that the sides are smaller by 20 cm, this is not a deception – this is such a method of designation. It is recommended to take into account the size difference before purchasing the product.
It is possible to list the positive characteristics and disadvantages of waterproof and vapor barrier reinforced film. You can talk about quality and disagree with the methods of size designation, prefer imported or domestic goods. But two indisputable advantages of reinforced film cannot be ignored: it makes a reliable shelter, and the process of laying the material becomes much easier.
