High-tech air curtain
The thermal curtain on the front door is a piece of equipment that protects against cold air currents from the street inside the building. The device operates from a powerful fan, which is built into the curtain and creates a high-speed flow of heated air. This contributes to the formation of an invisible obstacle that does not allow warm air to leave the room, and cold vortices to get inside..

One of the main concerns of the owners is a comfortable stay in the house, but, unfortunately, the efforts spent on wall insulation, improvement of heating systems may be in vain if warm air flows freely through the cracks of window openings and doors.

By its design, the equipment can be electrical and water, and depending on the method of installation – horizontal or vertical.
The most common electrical version of the devices. In comparison with water, they have a number of advantages: affordable cost and easy installation; there is a possibility of mounting anywhere in the room; protect against the ingress of dust and gases from the street.
Original design of the thermal curtain
The main difference between the water system is the absence of electricity consumption. However, the price significantly exceeds the price of electrical devices, and the possibility of installation is due to the presence of a nearby heating system or hot water supply.

Often there are options for horizontal installation above the doorway, but sometimes vertical placement of the thermal curtain is used. With this option, it should be much longer, and the flow will be directed in the horizontal plane..
Vertical air curtain for wide doorways
The heat fan is set based on the type as well as the type of model. To this end, it is necessary to determine the indicators for the width and height of the doorway, where then such a device and the speed mode of the air flow created by it will be installed. The following rule applies: the lower the location of the opening, the lower the speed should be. The installation of the thermal curtain should be carried out as close to the door as possible due to the fact that the device needs to cover the entire doorway.
The lower the doorway is, the lower the air flow rate should be.
It is recommended to mount several curtains with a wide door opening. In this case, the devices will be installed side by side, one after another, and, as a result, a single system will be created that will cover the entire room. The thermal curtain on the front door, the price of which will be increased in this way, guarantees its efficient use. You also need to take into account the speed of the draft that occurs inside the building – this applies mainly to rooms with a large area, which have several doors.
With the correct installation of the air curtain, the heated air flow enters the middle of the room even with the doors open and thus provides the room with additional heating
Advantages of using a thermal curtain:
- High degree of protection against polluted air, fine dust, exhaust gases, as well as various insects in the warm season.
Practical, convenient device for protection from external adverse factors
- Economical in energy consumption. Even taking into account that the device itself is a consumer of electricity, its use is of great benefit. It has been practically proven that the use of an air heating curtain, with its correct selection and installation, makes it possible to save up to 30 percent on energy consumption, which is spent on heating a building in winter and cooling in summer..
The thermal curtain provides thermal comfort in the room
This process takes place as follows: warm air masses are lighter than cold ones, in this regard, they rise up, and, as a result, “heavy” cold air accumulates near the floor – thus a gradient is formed. Due to the fact that warm air masses move to the floor from the curtain, the temperature difference in the vertical direction is significantly reduced. As a result, the process of adjusting degrees in the middle position in the rooms in which people are located takes place..
The principle of operation of the air-thermal curtain
- Comfort. The heat curtain helps to neutralize drafts that have arisen in the room, thus reducing the likelihood of colds. In summer, thanks to this device, a comfortable coolness is provided due to the prevention of dust and hot air flows into the room..
With proper installation of the thermal device, it is possible to provide additional heating, and in summer maximum comfort and air purity are achieved.
The heat curtain creates a barrier between two different-temperature flows
The area of use of thermal curtains for entrance doors is very wide: cafes, office premises, catering establishments, restaurants, shops – places where people gather. Thermal curtains for entrance doors are widely used in equipped houses, thereby eliminating drafts. Many users are mistakenly believed that using the device requires high energy costs..
Thanks to a well-developed market, each customer will be able to choose a thermal curtain for a shop, private house, workshop, office or garage.
Manufacturers of thermal curtains for entrance doors have created a lineup that consumes a minimum of electricity, while having characteristics that allow you to create a comfortable temperature in the institution. The most effective option would be to buy equipment that has a thermostat. This device is completely automated and when the set temperature regime is raised or lowered in the room, it turns off by itself.
If the door is wide, it is recommended to install several curtains in a row.
Such devices are classified as follows:
- Mini. Installation takes place in a doorway of small dimensions (kiosks, cash desks, etc.). The maximum window width should be 80 centimeters, 150 centimeters high.
- Medium sized curtains. Installation is carried out in doorways from 2.5 to 3.5 meters in height.
- Large equipment. Mainly applicable in industry; openings can reach a height of 7 meters.

How to choose thermal curtains for entrance doors? When choosing the type of device, first of all, you need to focus on the length of the blowing nozzle. It should be remembered that in the case of vertical installation, it is 3⁄4 of the value of the door height, and for horizontal installation it is calculated based on the formula: ten centimeters are added to the width of the door, which will completely cover the entire entrance space. The performance of the air curtain is calculated according to the formula for the amount of possible pumped air per unit of time (1 hour).

All devices used to stabilize the room temperature have a power button and power control. Some have switches that change the intensity of the warm air mass. High-power devices are equipped with remote controls. It is also possible to install a thermostat, with the help of which the device is turned off if the set temperature is reached..

The price of such devices is calculated depending on a number of factors, and the main ones are the company that manufactures the device, its length and power characteristics:
- The type of heating element and its power indicators. The price of the device is determined in proportion to the installed power of the equipment.
- Heat source. The water appliance is several times more expensive than electric models.
- Controllability. The presence of a remote control leads to an increase in the price of the thermal curtain.
A kind of air-thermal curtain
Such devices are equipped with a high performance control system. They will easily fit into any type of design due to their inconspicuousness.
It is possible to use thermal curtains in large transport complexes, trading floors, industrial areas and other areas of business.
Installation of air curtains on revolving doors can be either concealed or conventional installation
The built-in curtain control system automatically controls the operation of the electric heating device, taking into account the frequency of use of the door. Consequently, the heat curtain will be fully activated when the door starts to rotate. But when the rotation stops, the device will work at reduced speeds, and if there is no need for it, it will turn off altogether (the temperature regime of the institution will correspond to the set norm).
Air curtain installation above revolving doors
If it is impossible to use an ordinary curtain, the so-called hidden installation method is used. The installation of the device is carried out behind a suspended ceiling, due to which only the lower part with a grate through which warm air flows exit will be visible. Due to this installation method, the equipment becomes almost invisible. The operation of the unit is fully automated, as with a revolving door: when the door is open, it is carried out at full power, in case of non-use – low-speed mode, and when the set temperature is reached – shutdown. This work allows you to achieve an energy-saving mode of consumption of heat and electricity..
Concealed installation of a thermal curtain
When installing the curtain in the ceiling, it should be borne in mind that, depending on the type of heating element, this will increase the fire hazard level in the building.
