Nice garage- warm garage. Even the most economical car enthusiasts will not argue with this. It is impossible to keep the gates closed all the time, and when you open them, cold air from the street rushes into the room. This problem is solved by thermal curtains, which separate the cold air outside from the stable, comfortable atmosphere inside with an air stream.
Curtains, like gates, come in different types and are installed not only in garages. This material is devoted to calculating the optimal thermal curtain for gates.
To choose a reliable and durable gate, to select a curtain for the room, you should consider the following parameters:
- The dimensions of the curtain are in accordance with the width and height of the opening.
- Curtain power (temperature of blown air).
- Air flow speed (air capacity).
They also take into account the type of coolant of the thermal curtain, installation diagram and method of controlling the device. In general, if you want to save time, it is better to entrust the calculation of a thermal curtain for gates to warehouses, industrial premises or car washes to professionals. You will only need to fill out a questionnaire, based on which the designers will calculate in detail the required power and size of the air curtain.
What if the gate is wide?
For a curtain to be effective, there is a simple rule: the width of the curtain (at horizontal installation) must be greater than the width of the opening. If necessary, install several curtains side by side to completely cover the width of the opening. It is better to choose a larger curtain than a smaller one - you won’t be able to save on this parameter.
The installation height directly depends on the air flow speed. The stronger the flow rate, the higher the curtain can be hung. The flow rate is indicated in the device passport, as well as the recommended installation height. The flow speed always decreases towards the bottom of the opening, this must be taken into account.
In addition, when choosing a curtain for a gate, allowances are made for the strength of the wind outside, which blows away the air flow of the curtain, and for the air temperature outside.. Such conditions in Russia are almost fantastic.
There are many programs for calculating air curtain flow. The maximum effect is achieved when professionals take part.
Calculation example

Let us give an approximate calculation for installing a thermal air curtain for a gate 1 m wide and 2.5 m high. A prerequisite is the presence of a vestibule.
For the given parameters, a curtain with a capacity of 900-1000 m³/h is required. According to the equipment data sheet of most modern air curtains, the flow velocity at the outlet will be 8-10 m/s, and on the opposite side of the opening (at the bottom when installed horizontally, and on the side when installed vertically) it will be 2.5-3 m/s. The width of the curtain is at least 1 m.
Please note that the equipment passport always provides the recommended installation height.
The power of the curtain at the given parameters must be at least 3 kW. Power is calculated based on the required 0.1 kW per 1 m² unheated room with minimal heat loss.
Gates in workshops and warehouses are equipped with PVC curtains in order to ensure long-term storage of products, safe work workers, convenient movement. Silicone curtains can achieve great benefits, which is why they are widely used in industry. Along with such canopies, they serve as an effective addition and directly replace gates in the warm season.
You can order PVC curtains for gates right now from the World of MSK Curtains and find out the full cost using. But first, we invite you to familiarize yourself with all the advantages of these products, which have proven themselves on the market as the most practical and inexpensive way to solve many industrial and warehouse problems.
Advantages of PVC curtains for warehouses
Thermal curtains arranged above the gate. The silicone strips are arranged vertically close to one another. There are several ways to manufacture and install thermal curtains over gates. The choice depends on the width, intensity and nature of the opening; climatic features.
The PVC curtain mounted on the gate can be reinforced using special installation. Silicone curtains with protective coating from insects, ultraviolet, infrared lighting; to add wear resistance. However, we will consider the main advantages that distinguish PVC curtains installed on gates below:
- . Canopies effectively support temperature regime And set level humidity, which allows you to conveniently store products of various types of consumption. Due to their high density, PVC curtains on gates effectively resist any drafts.
- Noise insulation. Mounted curtain for warehouse gates correct installation muffles noise well.
- Durability. Canopies are distinguished long term services. In case of wear, the strips can be swapped or replaced with new ones individually.
- Versatility. PVC curtains for warehouses are suitable for covering openings of absolutely any width and height.
- Ease of use. Curtains do not obstruct the movement of vehicles. Natural light penetrates intensely through the thermal curtains. The curtains are easy to install and dismantle; if you wish, you can remove or replace the strips yourself.
- Easy to maintain. Simply wipe the curtains with a damp cloth to make them clean. No need to open and close manually.
- Safety of use. The use of canopies meets the technical standards, labor protection and safety rules established for workshops and warehouses. The plastic used is non-toxic and absolutely harmless to environment and human health.
Industrial curtains and drapes are economical!
Installing a PVC curtain on a gate can significantly reduce costs. Let's name the main points on which you can regularly save decent money using silicone curtains.
PVC strip curtains - effective way maintain the desired temperature (warm or cold) in the room: PVC curtains are what you need for your warehouse, workshop, store or production!
At many enterprises, the problem of energy saving arises due to constantly open doorways through which people pass. vehicles and the staff passes by. Equipping openings with doors would be too inconvenient, especially since there is an excellent alternative - PVC curtains made of durable material.
Many enterprises and warehouse complexes are faced with the problem of maintaining a comfortable temperature inside production and storage facilities, shops.
With the constant opening of doors and gates for the passage of personnel or the passage of equipment, an exchange of air occurs between the room and the street. IN winter time cold air enters the room and heating devices“they warm the street”, and in the summer heat air conditioners do not cope with their tasks.
PVC curtains for gates. Thermal curtains
PVC curtains for gates – perfect solution For entrance gate. PVC gate curtains are installed for workshop gates, warehouse gates and garage doors. Silicone curtains for gates are safe and resistant to loads during the passage of small to small vehicles. PVC curtains for gates open only part of the opening, according to the size of the passing person or the cargo being moved. PVC curtains for gates do not require the driver to exit: the equipment simply drives through the PVC curtains, and the curtains on the gates almost instantly return to their original, vertical position and hermetically close the opening.
As practice has shown, strip curtains ( plastic pvc curtains, thermal curtains) can significantly save on energy consumption.
PVC strip curtains can be selected based on the following rule - the higher the opening, the greater the overlap (overlap of strips) and the width of the strip should be.
The price of PVC curtains depends on their type and width. You can order and buy PVC curtains from our company.
Strip curtains are divided by type into smooth and corrugated, and by width: 200x2 (mm), 300x3 (mm) and 400x4 (mm).
Types of PVC curtains
Depending on the type and purpose, PVC strip curtains are:
- smooth
- corrugated
- non-flammable
- with special impregnation that repels insects
— frost-resistant curtains for refrigeration chambers
Smooth strip PVC strip curtains are used for refrigeration chambers, doorways of shops and enterprises, separating work areas in enterprises - a transparent “wall” of curtains successfully performs the task of eliminating drafts, maintaining the necessary thermal conditions, sound insulation, and protects from dust, leaves and insects , transmits a sufficient amount of light. At the same time, it does not interfere with the free passage of personnel.
Corrugated PVC curtains have special stiffening ribs; they are recommended to be installed in the gate openings of enterprises and warehouses with a large flow of loading equipment. The ribs of the curtains are designed to eliminate the moment of “sticking” to the parts of forklifts and equipment, which happens with conventional curtains. The sliding resistance of such curtains, thanks to the longitudinal “ribs,” is minimal. The ribs of the curtains reduce the contact area, thereby significantly reducing friction. In addition, the ribs of the curtains take the entire load on themselves, which allows the main part of the curtain to remain for a long time clean and without scratches. At the same time, such curtains quickly return to their original vertical position, closing and closing the opening.
PVC curtains for refrigeration and freezers
Frost-resistant PVC strip curtains for refrigerators and freezers with temperature differences from -40 C° to +25 C°: PVC curtain for the refrigeration chamber (Silicone curtain) is designed to protect refrigeration chambers from loss of cold/heat. Frost-resistant PVC curtains for refrigeration chambers contain a high percentage of special plasticizers, so such curtains retain the elasticity of the material and do not break under conditions low temperatures. You can buy frost-resistant PVC curtains for refrigerators in Moscow at prices from the manufacturer.
PVC strip curtains
Non-flammable PVC strip curtains (non-flammable) are used in places with increased fire hazard - warehouses with flammable substances, paper, paint. In the event of a fire, PVC curtains prevent the spread of fire throughout the warehouse or enterprise. Such curtains can be used in welding areas - they prevent the scattering of sparks during welding or metal processing. Strip curtains for welding work are produced with a special coating that acts as a filter to protect personnel from glare from the welding arc.
Curtains with special impregnation have chemical composition repels flying and crawling insects - flies, wasps, mosquitoes, horse flies, cockroaches, ants. The use of such curtains in catering establishments has shown their high efficiency.
Installation of PVC curtains
The device of fastening combs allows you to fasten PVC plastic curtains in any opening of a door or gate. The length of the comb must correspond to the width of the opening. Installation of strip curtains is simple, can be done in a short time independently, and in the case of large volumes or complex configurations of openings, it is better to contact our specialist installers. For self-installation silicone curtain, you need to mark the bottom line of installation of the comb with a marker. The comb must be installed strictly horizontally. The comb is installed on self-tapping screws, anchors, dowels, depending on the wall material and installation location. Required quantity fasteners depend on the strength and material of the wall. The length of the strip curtains should be such that there is 2-3 cm left from the bottom to the floor.

The thermal curtain for the gate to the workshop belongs to industrial type equipment. But the main function of such technology is similar to that implemented by other analogues - creating an air barrier for mixing cold air from the street and warm air from the room.
There is quite large selection such devices, which allows you to install them on any side of the gate: on the side, above it, along the bottom.
What are they used for and where can they be used?
A thermal curtain is installed in a production workshop to reduce heat loss in rooms where most of the time doorways are not protected from penetration through them. air environment from the street. This happens during loading/unloading and frequent entry of vehicles. But in addition to production facilities, such equipment is often installed privately - in garages. Another area of application is civil facilities, such as car repair shops.
Watch the video, how it works:
Thermal air curtain for the gate to the workshop allows you to significantly save energy, which is explained by the absence of the need to intensively warm up the room after each opening of the gate. However, the effectiveness of such technology is also affected by the location.
For example, in a garage or car workshop, where a picture is often observed when vehicles stop directly in the opening itself, it is highly recommended to use the lower airflow option, since the upper airflow warm air it simply will not block the flow of cold air due to a car standing in the opening.
What types of curtains are there, their design and operating features
Electric curtains
There are two types of equipment used today with unidirectional supply of heated air:
- Industrial thermal air curtains for gates are adjustable - they are equipped with a heater, through which the device warms up the air to a certain temperature;
- Mixing - operate on the principle of intake of outside air.
Similar equipment is also distinguished by operating mode: on a permanent or periodic basis. There is also a classification based on the direction of the supplied air flow:
- The flow moves from bottom to top. IN in this case devices are installed under the gates. As mentioned above, this method is not always effective, but only when cars often stop at the gate. However, there are also disadvantages to this solution - it clogs the mechanism too quickly, which is why maintenance is required an order of magnitude more often.
- Air movement from top to bottom. This classic way location of such equipment. The equipment is installed directly above the gate.
- The directed flow moves in a horizontal plane, which is realized by placing devices on the side of the gate.
By design, other groups are also distinguished:
- Thermal air curtains for water gates - operate on the basis of an existing heating system or hot water supply, which allows you to mainly warm up the air with the direct participation of the coolant;
- Electric - unlike the first option, they can be used almost everywhere if the site has a dedicated power source for connecting it, while water installations are used where there must be heating system or hot pipeline.
The principle of operation of such equipment is similar for all versions: air is pumped through a powerful fan built into the device body. His exit can be arranged in different ways, it all depends on the type of installation. But in any case, the design will provide a gap of a certain size through which air is supplied to the boundary of the object and the external environment.
Thermal air curtain for a garage or workshop is selected taking into account a number of parameters:
When choosing diesel or gas heat gun for a garage or a device for a workshop, in both cases it is important to correctly determine the thermal power of such equipment, which will allow the air to be heated at the required height and at a sufficient speed.
Watch the video, selection criteria:
When choosing a unit with the required power, it is necessary to take into account the volume of the room, as well as the level of its thermal insulation and the average temperature outside and inside the facility.
How to calculate thermal power and air flow
To calculate sufficient performance, it is necessary to approximately know at what speed air enters a room of a certain volume. To do this, multiply the value of the air flow speed and the volume of the room. The resulting value (L pr) is used to obtain the value of the required air flow using the following technique:
Lzav=Lpr/j(B/b+1),
where j is the coefficient that determines the strength of the flow created by the device, corresponds to a value of 0.45;
B, b – parameters of the slot through which the air flow will be supplied.
Calculation of the power of a thermal curtain for a gate:
Qset = 0.24Lstart (tstart – tstart),
where t h, t initial are the values of the average temperatures of the air curtain itself and the external environment, respectively.
Features of installation and operation
Such equipment is installed as close to the opening as possible. This achieves highest degree effectiveness in organizing a protective air stream. It is also important to ensure that the length of the device matches the width of the opening if the installation option above the gate is chosen. In the case when a vertical installation is mounted, then it is necessary to select its length based on the height of the gate.
All installation work on such equipment is carried out exclusively with inside premises. Another important nuance– monitoring the operation of air conditioning and ventilation systems to avoid additional impact on the operation of the device. If the gate is too wide, then several installations can be used. Their connection to each other in this case is realized through a special connecting kit.
Watch the video, installation and installation:
Depending on the type of device selected, the mechanism can be equipped with fastening elements: for wall or ceiling mounting. Control of such equipment is also carried out in accordance with the type of device. When installing a curtain, it is necessary to select anchors taking into account not only the main weight of the structure itself, but also the likely load in the event of vibration waves, which is especially important in repair shops and production shops.
Thus, selection and installation special equipment creating air curtains is somewhat more complicated than purchasing equipment such as a diesel heat gun for a garage. Although before purchasing industrial device Thermal power, air flow rate and operating efficiency are taken into account. But to these parameters is also added the need to choose an installation method (ceiling, wall, floor), assessing the load on the fastening elements and, of course, the dimensions of the equipment itself, which will allow you to create an air curtain across the entire width of the doorway or gate.
The Termomir store offers customers a wide range of thermal air curtains. Heat curtains are sold wholesale and retail on the official website.
One of the most effective options protection from the penetration of cold air into the room is a thermal curtain. Wide by air flow The device separates the heated room from cold air from the street, protects against dust and insects, provides a comfortable microclimate in the entrance area, saves energy resources for heating, and in summer keeps air-conditioned rooms cool.
Air curtains are installed at the entrance groups of buildings with a large number of visitors: in shopping and entertainment centers, metro lobbies, cafes and restaurants, large offices, banks, clinics, etc.
Curtains come with heating - electric and water (on hot water), and also without heating - air.
Electric thermal curtains operate from the mains, can be used for both household and industrial purposes, usually have several operating modes with power switching and can operate without heating ( summer mode). Air curtains with a power of up to 5 kW operate at a network voltage of 220 V, and from 5 and above - 380 V. Household air curtains are actively used for doors in country houses and dachas.
Water thermal curtains differ from electric ones in much greater power, therefore they are actively used for large objects - doorways and gates of large warehouses, shops, workshops, hangars, etc. Such curtains have a permanent installation, are connected to the main hot water and are characterized by high efficiency and air performance.
Air curtains without heating are used where it is necessary to separate the zone of heat and cold without additional heating. These devices are not equipped heating elements, but work as large fans, allowing you to separate refrigeration chambers, zones or warehouses with chilled products from heated rooms, to prevent smoke and dust from entering other rooms, for example, in working workshops and workshops, etc.
Thermal air curtains have the main technical specifications: power, air capacity and installation height. Based on these parameters, the calculation and selection of heat curtains is carried out. Dimensions are also important, or rather the width of the curtain - it should be sufficient to cover the entire doorway, providing complete protection.
Thermal curtains are most often produced in horizontal version and are placed above the door or gate on the wall or ceiling. Vertical installation curtains are placed on the side of the doorway and have important characteristic no longer width, but height. Sometimes, at high doorways, several such curtains are used, installed one above the other. There are also universal installation models that are connected from the side or from above at the user’s request. Thermal curtains quite often come with a remote control remote control– keyboard, wired or wireless. This device greatly facilitates the use of the curtain and increases comfort. Large assortment thermal curtains are presented below on the page and in the site menu. If you find it difficult to make a choice, contact our specialists for advice.
