What types of awnings exist and how to use them

Briefly - general requirements

All materials that are used to make awnings and various canopies must, to one degree or another, meet certain requirements. If we briefly list the special properties of such fabrics, we will get something like this.

• Durability . The very first characteristic is explained by the fact that covering materials must perform a protective function. The word strength means the ability to withstand mechanical loads without any damage - stretching, punctures, sharp gusty winds, and so on.
• Wear resistance . The longer the service life of such materials, the better. This reduces the cost of both time and money for changing materials.
• Resistance to rot . Since awning fabrics are used in difficult conditions, they must have the ability to resist bacterial growth and rot.
• Waterproof . Most often, awnings are used precisely to provide protection from precipitation and water.
• UV resistance . The alternation of moisture and the aggressive action of ultraviolet radiation has a detrimental effect on many materials and very quickly leads to their wear.

Tourist tents

Much more complex and varied are tourist tents - tents. Structurally, it is a rectangular or polygonal tent-tent stretched over a rigid frame. The fabric part of the awning can occupy only the upper part of the structure, protecting only from rain and sun. It can cover the walls, or part of them, together with the roof.

They can be with or without a windproof skirt around the perimeter. The rigid frame of such awning tents can be completely disassembled into its component elements, or it can be a complex technological structure that is not collapsible, but when folded, occupying a minimum of space. In cheap tents, the frame is made of steel or aluminum tubes (aluminum alloys). In expensive structures, this may be a complex fiberglass frame. Complex automatic or semi-automatic quick-assembled tents allow the installation of these monumental structures in a matter of minutes.

Various fabrics and materials are used to make tourist tents. Cheap awnings use impregnated cotton fabric or high-strength polyethylene. The same polyester .

Canvas group

Tarpaulin is one of the most common materials for making awnings. Despite the abundance of new materials, tarpaulin is still not losing its position in many industries where awnings or external protection may be needed.

Tarpaulin is a rough, dense fabric made from natural fibers.

Naturalness is the main difference from other awning materials that are made on the basis of polymers. By the way, this very quality can be considered an insignificant drawback, since in natural fiber, over time, favorable conditions are created for the development of putrefactive bacteria.

Special properties

Tarpaulin has a number of properties that are indispensable for awning fabrics.

• Wear resistance . Successfully withstands most types of mechanical loads - torsion, compression, bending, stretching, friction and so on.
• Durability . In addition to wear resistance, it also withstands chemicals well, which greatly increases its service life.
• Air permeability . Thanks to the ability of tarpaulin to pass air under pressure, it is possible to create a favorable microclimate. This is important for many industries, including agriculture.
• Low hygroscopicity . The fabric does not absorb water vapor from the air and the environment; accordingly, the covered materials remain dry.
• High density . The value of this parameter for tarpaulin ranges from 300 to 600 g/m2, which is ensured by the thickness of the threads and the tightness of their fit to each other.

The main color of this fabric is khaki. However, the color range has been expanded by its numerous shades - camouflage, light green, sand, etc.

Usage

In addition to various household, private needs and tourism, awnings made from tarpaulin fabrics are often used in industries such as construction and agriculture. With their help, temporary building structures (scaffolding), buildings for workers, unfinished and unfinished buildings, building materials, etc. are protected.

In agriculture, there is a need to shelter the harvested crop, machinery, equipment and other equipment that cannot be delivered to the garage and is stored outdoors.

Production

The basis for creating tarpaulin is cotton and linen . jute is also added to the weaving . It contains a large amount of lingin, an element responsible for fiber stiffness.

The ratio of linen and cotton fabric composition can be different for different manufacturers - 40 to 60, 50 to 50 or 60 to 40 percentage. Sometimes 100% of a particular material is used.

All kinds of impregnations that are used for processing significantly improve the existing properties of the fabric and give it additional characteristics.

• VO - waterproof . For use in areas characterized by high humidity. Special types of such impregnations can also be used - SKPV (light-resistant, combined fabric with increased water resistance), PV (increased water resistance).
• OP – fire retardant . This property helps to withstand high temperatures and even open fire for a certain period of time. By analogy with the previous type of impregnation, there is also a special light-resistant combined impregnation SKOP.
• PP – anti-putrefactive . Since tarpaulin is a natural material, it needs protection from the harmful effects of all kinds of microorganisms that cause decay processes. Variety - SKPP.

The cost of tarpaulin in relation to modern fabrics is low. Depending on the composition, impregnation and some other factors, the price per linear meter ranges from 55 to 200 rubles .

Tarpaulin

Tarpaulin is a synthetic material on a PVC fabric base, laminated on both sides with a light-stabilizing film. The edges of the canvas are sealed, there are eyelets (rings) along the entire perimeter, which allow you to attach the awning where necessary. The eyelets are installed one meter apart from each other, and a polymer cord runs along the edge.

It is lighter and cheaper than tarpaulin, has high strength, due to its plasticity it can take the shape of an object, does not allow moisture to pass through, protects from ultraviolet radiation, is resistant to sudden temperature fluctuations, does not conduct electric current, and is resistant to damage to the canvas structure by fungi.

Areas of application:

• road construction work;

• shelter for all types of transport: land, water, air, rail;

• tourism and travel;

• construction (sheltering of erected structures and houses, building materials, roofs;

• protection of swimming pools and artificial reservoirs, lining the bottom of the pond;

• sheltering vegetable and fruit crops, insulating crops at low temperatures;

An awning made of any material is suitable for protection from wind, sun, frost, snow, hail, and rain. All of them can withstand a wide range of temperatures. In addition, they are quite durable. Only a canopy made of tarpaulin with fire-resistant impregnation will provide the best protection from fire. However, it protects against fire for a short time, and then begins to melt. Thus, a construction awning can be made from various materials that will provide the greatest efficiency in the cases for which they are intended.

PVC group

Such fabrics are a material based on a fairly dense woven polyester mesh, which is covered on both sides with a thin and durable layer of polyvinyl chloride (PVC).

Properties

Due to their composition, PVC fabrics are very resistant to tearing and stretching. In addition, the material is able to retain its shape even under the most difficult operating conditions. This property is much more pronounced than, for example, that of the tarpaulin group of fabrics.

In addition, PVC awning materials have the following characteristics:

• resistance to UV rays and no fading;
• repel water;
• insensitive to aggressive environments, therefore durable;
• there are no changes with frequent and strong changes in ambient temperatures (from -30 to +70°C);
• prevents dirt and stains;
• service life is about 5–7 years.

The average cost of such awning fabrics is slightly higher than textile ones, but is also not too high. The price of one square meter of fabric for PVC awnings ranges from 160 to 320 rubles .

Selection of awnings by size and type

If you need an awning for a hike or a tourist outing, you should consider not only the comfort of placing each person under it, but also the weight of the bag with the awning. This often becomes a problem for hiking trips.

For hiking you need compact tents made of lightweight materials. But if you plan to go outdoors by car and install an awning , then you can neglect the compactness and purchase a large, full-fledged canopy, which will provide you with the following advantages:

• high level of protection from weather conditions;
• the ability to create maximum comfort under the awning;
• high-quality material from which the canopy is made;
• Possibility of closing the sides if necessary.

Modern awnings and awnings offer many features. Each addition to the standard equipment will cost you some money, but will also give you unique comfort in nature.

Rubberized group

One of the most popular methods of protection against water is rubberized fabric. The basis can be almost any natural, synthetic or combined material.

Thanks to rubber, which is applied to the base in various ways, in addition to the ability to retain water, the advantages of such fabrics also include special resistance to a variety of household chemicals, elasticity and great strength.

The only drawback of such materials is that they are not very puncture resistant. However, special additives and the latest production methods practically eliminate this disadvantage, so rubberized fabrics remain one of the main materials for creating awnings.

Production

Depending on the final characteristics required (including gas-tightness), rubberization can be done on one or both sides. There may also be different varieties of rubber applied, which may simply have general or special properties.

There are several ways to produce such awning fabrics.

• Rubberization by impregnation with a special adhesive composition made on the basis of rubber (rubber). This composition contains volatile substances that evaporate during the drying process. As a result, the rubber is tightly attached to the fibers of the base material.
• Coating on a calender (a special machine with rollers for continuous passage of sheet materials).
• Calender lining.
• Rubberization with vulcanization or impregnation with photopolymer is possible.

Rubberized awning fabrics, depending on the quality and final characteristics, can have different prices. The price range is quite wide - from 80 to 300 rubles per linear meter .

This material is sold in rolls 90–100 cm wide. The cost also depends on the strength, which can range from 150 to 750 g/m2.

Acrylic group

Like any fabric, acrylic is made from fibers. Continuous acrylic filaments are obtained from acrylonitrile, a special petrochemical product.

Key Features and Benefits

• Very high resistance to direct exposure to ultraviolet rays.
• Waterproof and also moisture repellent.
• No burnout. This is ensured by the fact that the fibers are dyed in their “raw” form, before the fabric is made.
• Excellent strength characteristics and no deformation during long-term use.
• Protected from dirt and wrinkle formation.
• Low thermal conductivity, which allows you to maintain a certain microclimate for covered materials.
• Wide temperature range for use – from -35 to +55°C.
• The fabric does not interact with most household chemicals.
• Acrylic fibers resist the formation of mold and mildew, and are also inedible to moths and parasites.

Example - materials from Sunbrella

This American company has been producing synthetic fabrics for awnings, awnings, covers and much more for about half a century. One of the most popular names is Sunbrella Plus fabric, which is made from 100% high quality acrylic.

Among its distinctive properties is the presence of both good breathability and the ability to repel water . That is why conditions are created inside the tent that do not allow bacteria to develop and mold to appear, since there is enough air there, but there is no dampness.

If you buy a Tarpaulin awning, you don’t have to worry about its quality - it will last quite a long time. Are you the owner of sliding gates? Know that a spare set of rollers for them will never be superfluous.
