When we are hot, we dream of coolness, and in the coldwe strive for warmth. Therefore, the appearance of a material such as a heat-reflecting film was due to a person's desire to create comfortable living conditions in hot weather and in cold weather. Today we will consider what it is.
Applications
Heat-reflecting film is used in many stages of construction:
- Roofing. In this case, depending on the species, it can not only retain heat, but also serve as a waterproofing.
- For insulation of walls. It can be used both for external wall finishing and for interior decoration.
- For the floor. In this case, the heat-reflecting film for the floor is used with both the conventional device and the installation of the "warm floor" system.
- For windows. There are two types of reflector. The first is energy saving, the second is the reflector of the thermal effect (keeping the cool in the heat).
- Another function is the use in horticulture for greenhouses.
- Glasses of cars and public transport.
As can be seen, this protection can be used both for the preservation of heat and for the reflection of thermal effects.
Indications for use
Almost any room has windows.They serve as a source of light and natural ventilation. As a rule, they occupy 25-30% of the wall area. And if it was made the insulation of the floor, walls, ceiling, then what are the windows? And through them it takes up to 60% of the heat in winter. Therefore, a number of technologies were developed:
- An ancient way of winter protection is all the joints betweenthe window and the frame were sealed with cotton wool and sealed with special paper. Everyone remembers that with such winter warming it was problematic to ventilate the premises.
- Instead of wooden windows, they came up with plastic with a tight fit that saved drafts.
But even this did not save us from heat loss.Because the main source of inconvenience is the glass itself. The first thing you came to is to cover the windows with curtains and blinds in the heat. Then they began to glue in all possible ways foil sheets, which acted as reflectors. This eliminated heat and natural light, which also caused a number of inconveniences.
Characteristics
With the development of nanotechnology, metallized films began to be replaced by new, polymer ones. The main difference is improved performance, durability.
Due to what this type of heat reflector was receivedpopularity? First of all due to its external characteristics. Such films do not change the appearance of buildings, so another name for them is architectural. And the main thing is that they let visible light and delay up to 75% of the thermal radiation in the summer. And in the winter they work in the other direction - they reflect the internal heat back into the room, while allowing visible light to come from outside.
Advantages and disadvantages
The window film heatreflecting possesses a number of indisputable advantages:
- Ease of installation and dismantling. Easy to paste allows you to do the installation yourself.
- Durability. The density of the film allows it to be washed and operated as a regular double-glazed unit.
- In the summer, savings on air conditioning, and therefore, less electricity consumption.
- In winter, savings on heating, which will also reduce the cost of electricity.
- Aesthetic appearance. The film has a light grayish or blue outflow. Can be used for buildings of historical value.
- Ease of care. Cleaned like normal windows.
- Maximum protection from ultraviolet radiation and infrared radiation, while passing visible rays, which creates comfort for human eyes.
- Security. If glass breaks, then it remains fastened with a film, i.e. it does not shatter into small pieces.
- Noise isolation, reduce noise.
- Affordable price. The average cost per square meter is 550 rubles.
- The ability to use the window at any time of year as a source of natural ventilation and light.
The disadvantages include a ban on washingcleaning powders and the use of hard sponges. It is recommended to use soft cloths and rubber wipers. As can be seen, the heat-reflecting film, in addition to its main function, is a means of saving energy consumption costs.
Installation and operation
As mentioned earlier, the installation of the film is nottakes a lot of time and does not require professional hands. First you need to thoroughly clean the windows and degrease their surface. Sticker film is made from the inside. The protective coating itself has an adhesive backing covered with a protective film. If the size of the glass and film does not match, it should be cut to size. Next, you need to remove the protective layer and glue on the glass, smoothing the surface with a soft cloth. For convenience, you can remove the protective film not all at once, but gradually, as it is glued, to prevent the formation of bubbles.
Reviews
According to numerous responses, one of the favoritesis an IR Sky Blue heat reflecting film (SRC HP7575). This is due to the aesthetic appearance of the building after the pasting of this protection and its effectiveness. The film itself has a weak grayish or blue outflow. Such protection is also used for car windows, public transport.
Heat-reflecting film has a number of advantages,which make it as attractive as possible. Efficiency, the ability to carry out installation with their own hands allow us to consider this material interesting for consumers.
