What is the roller shutter window
Rolling shutter
English: rollershutter
Rolling shutters originated in Europe, roller blind products have been more than 150 years old, it evolved from wooden louver, although through the wood, plastic, steel, hollow aluminum alloy until today's popular double-layer aluminum alloy Different periods of polyurethane foam fillers, however, it always combines the technology of the time to reflect the human living space. The German industrial standard DIN 19073 defines the roller blind as follows: "The roller shutter is a retractable spacer that is additionally used as a hole." The roller shutter is usually mounted on the outside of the glazing, its main components are It is made of aluminum alloy, so it has a long service life. The common driving method is indoor belt manual, crank rocker manual or electric.
Rolling shutters have several important advantages:
(1) Insulation performance - can greatly save energy for cooling and heating
The window is the main channel for daylighting in the living room. It saves the energy needed for lighting and is the channel through which people's sights come into contact with nature. However, it also brings a lot of troubles. For example, in the winter, especially in the north, it loses valuable indoor heat to the outside; in the summer, it transfers excess heat to the room, making people need a lot of electricity ( Air conditioning, etc.) to balance the temperature inside the room.
In order to obtain the desired insulation effect, the following points should be noted for the roller shutter:
1. The tightness of the closing of the rolling shutter;
2. The sealing property of the contact portion between the roller shutter and the roller blind cover;
3. Airtightness at the rail;
4. The tightness of the combination of the guide rail and the wall;
5. The sealing of the roller window strip and the window sill;
6. Thermal insulation performance of the rolling cover
(2) Sound insulation performance
Usually people want a quiet living room, especially close to the street and the road. The sound insulation of the window can be greatly improved by using a fully closed shutter window mounted on the outside of the glass window. Through research, it has been found that the greater the distance between the roller shutter window and the glass window, the better the noise reduction effect. The closed roller shutter window itself can reduce the noise by 18dB. If combined with the insulating glass window (4/12/4mm), it can achieve a comprehensive sound insulation of 37dB.
In order to achieve the desired sound insulation, the following points should be noted:
1. The tightness of the closing of the rolling shutter;
2. Airtightness at the rail;
3. The sealing of the roller window strip and the window sill;
4. The roller blind cover has sufficient insulation to avoid the formation of a sound bridge.
(3) sun protection, shading performance
In the winter, people hope to warm the room through the sunlight through the glass window. The hot sun in the summer is the last thing people want. At this time, only a small part of the light is reflected by the glass window, and most of them are shot through the glass window. When I arrived indoors, people asked for a sunshade.
Although there are various sunshade methods, the roller shutters installed on the outside of the glass window are one of the most ideal solutions to solve the problem, because one of them, the roller shutter can reflect most of the sunlight; Second, the roller shutter window can also arbitrarily adjust the sunlight/light entering the room; thirdly, its use basically does not occupy space. By reducing the amount of heat entering the room, one can save a lot of power for the air conditioner.
If you choose a light-colored roller blind profile, you will be better able to improve the reflection of sunlight.
(4) Weather resistance
Roller shutters are resistant to wind, rain and snow. Add a protective barrier to the doors and windows of the building.
(5) Anti-theft performance
The roller shutter window is also an attractive protective device. The fully closed roller shutter window can prevent the glass window from being damaged by bricks and balls, and can also prevent the thief from invading. The understanding of the aluminum alloy roller shutter in the anti-theft is that it can prevent the invasion of the thief to a certain extent. Taking certain measures will greatly improve the anti-theft performance of the roller shutter, such as:
1. Reinforced roller blinds, such as double-layer steel-filled polyurethane profiles, double-layer aluminum profiles filled with super-hard polyurethane;
2. Use reinforcing rails to increase the depth of the guide rails;
3. Strengthen the connection reliability of each fixed part;
4. Using a locking or anti-pushing mechanism;
5. In the form of concealed on the building (ie the roller blind guide, the cover is placed inside the wall)
(6) occlusion of sight
A closed roller window can be used instead of a curtain to block the line of sight from the outside.
In addition, as an ideal product to replace the current anti-theft iron fence, it has the following advantages:
(1) completely changed the drawbacks of the iron fence to isolate people from nature;
(2) While adding a tranquility to the living room, it also retains the passage with the outside world; it avoids the problem of the iron fence in an emergency, such as a fire, blocking escape and rescue passage;
(3) While blocking the entry of the thief, since the roller blind can be borrowed as a climbing device unlike the iron fence, this will change the condition of the whole building closed by the iron fence;
(4) It will greatly change the facade effect of the building and beautify the city.
