Reinforced film, the reinforced tarpaulin and other types of tents

Reinforced film, the reinforced tarpaulin and other types of tents

Process of cultivation of vegetables and berries can be separated into two stages: construction of the greenhouse and care of plants during their growth. Whether it will turn out to regale on spring strawberry and whether there will be on table crackling cucumbers – in many respects depends on that as well as of what material the greenhouse will be built. The used by gardeners covering reinforced film, reinforced tent or the special material tarpaulin create the most comfortable conditions for hothouse plants.

Main characteristics of reinforced film

Long time for greenhouses the polyethylene film was the only thing covering material. It met many requirements, but after one year of use grew turbid, passed light much worse. And the integrity of cloth most often within one season could not be kept, it was easily damaged even at insignificant mechanical influences.

The reinforcing film which has appeared in the market for greenhouses has practically forced out normal polyethylene. It has not lost any technical characteristic of this material, and in it the main defects of normal polyethylene are eliminated.

The reinforced cloth presents itself framework in the form of grid on which the polyethylene film on both sides is built up. Availability of dense grid also allows to use this material as reliable covering and gives it number of considerable positive characteristics.

Advantages of reinforced film:

  • it is steady against stretching, maintains considerable mechanical damages;
  • has waterproofing and vapor barrier properties;
  • maintains considerable fluctuations of temperatures (from-30 to 90 °C);
  • it is long-lasting in use (5 years and more).

This material is steady against ultraviolet, maintains the difficult weather patterns which is characterized strong up to heavy, wind, rainfall in the form of heavy rain and hail.

Reinforced film, the reinforced polyethylene and membrane: properties of materials

Release several types of reinforced film. They differ both with structure and the amount of frame weaving, and quality of the built-up polyethylene layers.

The framework is executed by interlacing of threads which are created from the following materials:

  • fiber glasses;
  • polyethylene;
  • polypropylene.

Thickness of threads different that influences durability and weight of reinforced film. Cells can also differ by the size. Film with large elements more photoconductive, the small sizes strengthen durability material covering. In truck farming use generally the film having the size of cells of 1.5х1.5 cm. Such format provides optimum comfortable conditions for plants in greenhouses and hotbeds.

The films which are built up on framework differ in thickness, density and additives which improve functional characteristics of material.

Additives provide the following properties of hothouse films:

  1. Hydrophilic. Prevent education on inside of film of drops of condensate which inevitably would fall down on plants. Moisture flows down on greenhouse walls.
  2. Antistatic. These additives allow to push away dust from outer side of film, without allowing to be formed by dirt layer which will complicate light penetration.
  3. Heat-protective. Interfere with heat exit which has accumulated in the greenhouse.
  4. Light stabilizing. Protect film from destruction under the influence of sunlight.

There are also membrane films, t. e the having microscopic openings in each cell through which air – the so-called “breathing” films gets into the greenhouse.

Form of production of reinforced film – rolled. Length of standard parcels – 10, 25 and 50 m. Sometimes rolls 100 m long meet. Width of film can be 2, 3, 4 or 6 m. At taking-up in roll for convenience of transportation wide fabric is put: 3-4-meter – in half, height of parcels turns out respectively 1.5 or 2 m; the film 6-meter is put three times owing to what height of roll reaches 2 m. Cloths are hermetically packed, inside there shall be leaf with characteristics of goods.

Helpful advice! Upon purchase of roll of reinforced film it is necessary to pay attention to integrity of packaging surely. If she is damaged, great probability that there are defects and on the material.

What can be reinforced the reinforcing film

The range of application of reinforced film is extensive. It is used everywhere where there is need to build temporary rooms, to cover the building, materials, objects, apertures or plants from rainfall, moisture penetrations, from winds, low or high temperature.

The main spheres where reinforced film is used:

  1. Industrial and private gardening and truck farming. It is covering material for hotbeds and greenhouses, temporary vegetable storehouses, canopies, silage holes are constructed from this film.
  2. Industry and construction. Do warehouse of the facilitated designs of the reinforced polyethylene fabric, it close unfinished objects, preserve the equipment in production workshops, do barriers for temporary dumps, spread on floor as waterproofing. As the impervious material film is used when performing roofing works.
  3. Life. The film for protection of furniture, electrical equipment and other household items against moisture and low temperatures is applicable. It is used at arrangement of decorative ponds, for protection against penetration into the room of cold air and moisture through wooden window frames, for waterproofing of wood structures and floorings.

Active use of reinforced film in different spheres of production and life is promoted by its elasticity, flexibility and small weight. It is possible to fix, dismantle and transport this material, for work with film difficult and expensive tools are not necessary, special skills are not required.

What needs to be known, choosing reinforced film for greenhouses

Before covering the greenhouse with film, it is necessary to calculate carefully the sizes cloth covering. It is necessary to count subcollars, bends taking into account features of framework structure. Reinforced film does not stretch, to pull it it will not turn out even on 1–2 cm.

Special attention needs to be paid for the color. That for plants optimal conditions have been created, it is better to choose white film. It least of all detains sunlight (transparency – 85%). If to consider that reinforcing and so enough noticeably reduces this indicator, then, using film green or blue, it is necessary to be ready to lowering of illumination for 5-7%. It is possible to get color covering only if to greenhouses types of cultures for which such conditions are acceptable land.

For photophilous plants it is necessary to choose film with big cells of 1.5х1.5 or 2х2 cm.

Significant indicator – density. Material durability, durability of use and the price depends on it. Traditionally for greenhouses from 120 to 200 mdt choose material.

Helpful advice! Buying reinforced film for greenhouses, do not rely only on the information (concerning density) placed in card of goods of online store or heard from the selling assistant. Surely demand the certificate of quality of goods where exact data will be specified. Visually and to the touch density of reinforced film cannot be determined, and unfair sellers often use it.

The main characteristics to which it is necessary to pay attention upon purchase of reinforced film:

  • sizes of cells;
  • color;
  • density;
  • availability of the additives enhancing consumer qualities of film (hydrophilic, light stabilizing, antistatic).

Often preference is given to reinforced film 200 of mdt. It belongs to mid-price segment, maintains considerable mechanical loadings, it is easy to work with it. However it is possible to buy reinforced film 400 of mdt for the greenhouse. The price of such material it is insignificant above – for 3-4% concerning the cost of film with a density of 200 mdt.

If to find from preparation fabric, to stick together their hot (by means of the soldering iron or blow torch) or in the cold way, applying glue structures, then the cover on the greenhouse from reinforced film 400 of mdt which is convenient for putting on framework at the beginning of season will turn out and to remove upon termination of it. It is not necessary to spend time for laying, fixation of cloth, will not be risk to damage it during fixing.

Reinforced film for greenhouses: responses of consumers and councils of practicians

In front of the greenhouse equipment useful will be to obtain the opinions of those who already used film. Any instruction does not consider all subtleties and nuances which arise during practical application.

“Film of Leno, 170 microns. This year the second time covered. Normally, it is worse to pass light did not become. I have rectangular greenhouse, eternally there were problems with sagging of cloth. With this not so: both has fixed, and lies – any hollows”.

“Film with rigid grid, ideal. However, it was necessary to correct framework. Equal cut off lines, and the curvature of the beaten rails began to appear at once. But now and itself it is happy: excellent costs small greenery. The grid refracts sunshine, and inside warmly not burning, but soft, moderate. So far cucumbers, salad, radish normally develop. Not for nothing has spent money”

“Heard opinion that for year of application the armored lattice remains whole, and the film is scattered. Nothing for two seasons it was damaged and there cannot be it if only not to make a hole in grid. By condition of material it is happy, sure, as the third season (or perhaps and more) I will use this film”.

Reinforced film, the reinforced tarpaulin and other types of tents

In separate responses users give advice to which it is worth listening.

“I have on the greenhouse reinforced film of 200 microns. Strong, in two years absolutely has not torn anywhere. The greenhouse is big, nearly 30 squares. I and adhesive tape have prepared to patch, but it was not necessary. However, itself has made mistake. The framework from tree, and beat film the stapler furniture. Brackets through each one and a half centimeters. When removed them, has done holes. It in the first year of application. And in this season has enclosed tape which pack boxes with heavy machinery, and has punched through it film. And it is more reliable, and I will not do holes when I remove. And it is possible and just to enclose film from dense polyethylene.”

The main shortcomings specified in separate responses generally concern fragility of use.

“So much money this reinforced film precisely is not necessary. When pulled polyethylene, I at least knew that it for year. And here have promised at least 3 seasons. Its ambassador of the first there is already a wish to throw out! Of holes it is full, dirty”.

“Reinforced film was not pleasant to me. In cloudy weather in the greenhouse in general it is gray. And at all it is not strong. There was strong wind, branches, without leaves as the early spring was flew. At us hot dry winds often happen at this time. Of holes it is full. I cannot tell, as indeed cell empty, but having punctured much. Density not the biggest – 120 microns, but expected the best. I do not know what until the end of season will be. It is disappointed”.

Opinions, of course, different, but mainly positive contents. On the basis of responses (from experience of practical application) it is possible to draw conclusion that at appropriate use, i.e. taking into account characteristics of this material, reinforced film nevertheless confirms the stated qualities and the guaranteed operation term which is 3–5 years.

Reinforced film in the industry: assignment construction covering of tents

One more rather wide scope of reinforced film is construction. Having started object from scratch, it is almost impossible to complete it during the spring and summer period. The stored materials, open rooms need protection against autumn rainfall and winter cold weather. And this function is performed by construction tents.

If there is need to cover insignificant amount of building materials or the small room, it is possible to get film and to make tent independently. The film should be bought by density from 120 microns. If the tent is used as the shelter of the room insignificant time, film material can just be pressed heavy objects, but it is obligatory with smooth surface not to damage polyethylene layer. At covering of building materials it is simple to pull together bottom of tent with vinyl packaging tape.

It is convenient to use construction tents with eyelets. Ready options are always issued with such openings throughout which the rope or rope is easily passed. Eyelets can be put and independently, having bought them in specialized shop. And if the tent of the small sizes and eyelets are necessary small, they can be got in department of shopping center where sewing accessories are on sale.

Choosing construction tent, it is necessary to consider the following factors:

  • intensity and term of use;
  • what weather patterns will influence material;
  • whether availability of the fixing elements is necessary.

Proceeding from above-mentioned factors, density and the sizes of material are chosen.

The weighed approach to the choice will allow to save as much as possible means and to receive the expected result.

Prices of reinforced films and producers of material

The retail chain stores offer reinforced film of import and domestic production. The good selection, material has different technical characteristics. The Korean products differ in high quality and the corresponding price. Leno film enjoys special popularity. Material has different density, polyethylene films are issued both with different additives, and without them.

Among the Chinese products there is reinforced film for greenhouses which price is much lower, than at analogs. Naturally, material of low quality. But the goods are available to the consumer and therefore are in demand.

Among the Russian producers, products differ in high level of quality. Frame thread is made of monofibre, strong. Films with the additives protecting from the destroying influence of ultraviolet perfectly are suitable for covering of greenhouses. The plant releases cloths of different width including large-format – 6 m. Products are protected from fakes by special type of marking – red threads.

Also Stren film is competitive. Material the strong, reinforcing framework is made of polypropylene. Polyethylene layers have the enhanced antistatic and light-tight properties. The plant releases films with different sizes of cells that gives the chance to choose optimum light transmission ability.

The price of the reinforcing film in many respects depends on material density. The it is more, the cost is higher. Usually the price of these goods for roll is specified, is more rare – for running meter. In some cases the price of reinforced film for m ² makes a reservation.

Let’s take for comparison of the price, specified by the trading companies. Film the reinforced STRONG 120/2/25, average cost – 50/rm.

Comparing the prices, it is possible to draw conclusion that increase in density on 80 g/m2 triples the price practically. The cost of analogs of the Korean production is 3-7% higher. The products made in China and belonging to the class the house-keeper have the price of other films 10-15% lower than cost with the same characteristics.

Helpful advice! Buying reinforced film of any producer, read information on goods on packaging. If there are no data – the goods are not certified, and it is better to refuse it.

Tarpaulin fabric manufacturing techniques

Rather recently the new look material covering – tarpaulin has appeared. It is made of polyethylene. Process of production reminds fabric manufacturing techniques. Threads, only not natural, and from melted polypropylene intertwine. Threads make dense basis which from two parties is laminated by opaque polyethylene. As a result the material in many respects exceeding on utilization properties turns out applied to concealment polyethylene. It is import material, it is manufactured in Turkey, China, Korea, Poland and other countries. The price of tarpaulin is much lower.

Fabric has pleasant blue or green color and has number of high qualitative characteristics:

  • easy, is much easier than tarpaulin;
  • hydroimpenetrable and vapor-tight;
  • strong on gap;
  • elastic;
  • resistant to ultraviolet;
  • has low cost.

Initially tarpaulin used during road works. But practically at once the sphere of its application has considerably extended: began to do tents of fabric. Today for this purpose the covering of material is not present worthy alternative and the competition.

Construction tents of tarpaulin: application without restrictions

The main qualities of the material given covering do its use possible for the different industrial, commercial and household purposes.

Tarpaulin has different density. Minimum – 50 g/m ². Bags for sugar are made of such fabric. Apply tarpaulin which density of 65 g / m²i above to production of tents.

The elasticity of material allows to cover objects of different configuration. The tent can be established on framework – the great temporary shelter will appear. If to connect several tents, the big cloth by means of which it is possible to equip the temporary big warehouse will turn out. tarpaulin bed curtains in construction are often used for creation of canopies and also for protection of cargo materials in transportation time.

Helpful advice! As cloth for the shelter of building materials you should not choose tarpaulin possessing with a density less than 120 g/m ². Friction about rigid surface are inevitable in that case, and it can reduce tent life cycle considerably.

Edges of tents from tarpaulin are always in addition strengthened by means of the polypropylene strip which is sealed inside. Eyelets at distance of 1 m from each other are inserted into dense part of tent (along edge). Extreme, angular eyelets of which the maximum load is the share have additional plastic inserts.

The sizes construction tents can have the most different. At small parameters fabric of small density is used most often. For example, the construction tent of 2х3 m is made of material which density of 65-100 g/m ². Usually is issued without eyelets and has the budgetary price. It is demanded option of the shelter for not long time. In addition to direct assignment, the tent can be used in life, during hikes, fishing where it will perform function of tent or canopy.

At the sizes of 4×5 m the construction tent already has eyelets and is made of more dense fabric (from 75 g/m ² above). Though also economy options meets fine fabric. At the considerable sizes of cloth (100 m ² and more) reinforced film which density begins from 170 g/m ² is used.

tarpaulin tent: responses positive and negative

The multifunctionality of tents from tarpaulin promoted emergence of significant amount of responses. Qualities, the cost, exterior are estimated. As for the price, here everyone has option. Practically all estimate exterior as visually pleasant, esthetic. Concerning quality different opinions meet.

“In terms of water-repellent properties such tent quite good. If it is good to record, no dirt will get. But here I will argue on durability. He does not seek, but it is easy to make hole. I is unintentional, even without applying force, has made a hole in tent the palette. Of course, the defect was quickly eliminated, the patch was imposed, but the fact of damage is”.

“Such impression that eyelets keep on anything. In the first trip two have escaped. And, above all – it is impossible to replace with same, are necessary big by the size. And such I did not even meet. To replace there is nothing, I begin to get used to holes. Perhaps who will prompt where to look?”

“The excellent tent, easy, strong, I also use, and I give all who ask. Chose dense, 180 microns. Looked for that eyelets were not from plastic, and metal. Two of them are already lost. The problem is small, covers still qualitatively, keeps well, but, probably, defects were allowed at installation of these rings. Even there was thought of return of goods”.

Poor inserted eyelets – problem which in responses meets rather often. The main mass of opinions – positive.

“Easy, I one cope with the sizes of 5х8 m. I use half a year, there are no defects anywhere yet. Heard what needs to be held one sun less, I remove and I put when it is not necessary”.

“When over my unfinished house did such thin roof, I have been skeptic. But builders have been sure of correctness of the actions, and I only silently observed. Moreover have also connected together blue tents, have made from two one, ring in ring. At first I resorted to check after each rain. Even these tarpaulin tents have sustained snow. Now I joke that I want to live under this blue sky.

It is a little contradictory reviews of tarpaulin. As shortcoming weak eyelets dominate. As advantage users mark out ease, variety of the sizes, the price and reliability of protection against rainfall.

The reinforcing film: additional information for exacting buyers

Sometimes happens not easy to understand quality of goods. You obtain convincing information from the seller, you buy goods, and he breaks, seeks, fails much earlier, than the warranty period expires.

Upon purchase of reinforced film for greenhouses use for production not of primary, but secondary raw materials can be reef. How it is possible to learn it? It is necessary to understand this question most: any seller manager will not share such information even if he will own it. Be not tempted on cheap goods if on it it is not marked that this economy offer. Attentively read information on film.

Surely study data on the manufacturer (the address and phone numbers), about the product sizes, technical characteristics including the description of structure about density and other characteristics taking into account additives. If according to information it has not turned out to make complete idea of goods, it, most likely, is not certified, therefore, it is possible to forget about quality assurances.

For those who are going to buy tent from tarpaulin useful will own the following data. When cutting fabric for production of tent use two technologies, more precisely, two accounting of the sizes. The first option – when official is the finishing size i.e. if parameters of finished product are specified.

The second type of designation of official dimensions – on cutting of cloth, i.e. on tent is specified the amount of preparations. Naturally, the cloth is bent, part leaves on seams. These are tents of “tarpaulin”. If material with sizes of 3х4 m is bought, and it has turned out that the party is 20 cm less, it is not deception – it is such method of designation. It is recommended to consider difference of the sizes before purchase of goods.

It is possible to list positive characteristics and shortcomings of waterproof and vapor barrier reinforced film. It is possible to argue on quality and not to agree with methods of designation of the sizes, to prefer import or domestic goods. But it is necessary to recognize two indisputable advantages of reinforced film: from it the reliable shelter turns out, and process of laying of material becomes much simpler.
