The secret of the external sunshade rolling window is popular for a century

Outside the sun shutter window has the following important advantages:
1. thermal insulation performance can greatly save the energy of refrigeration and heating
The window is the main channel of lighting in the room during the day, it saves the energy needed for lighting, and it is also the channel for people's sight to contact with nature. However, it also brings a lot of trouble. In winter, especially in the northern region, it loses valuable indoor heat to the outdoor; In summer, the outside heat is transferred to the indoor, so that people need to use a lot of electricity (air conditioning, etc.) to balance the indoor temperature.
Although modern technology has brought about multi-layer glass, expensive window frame structure and joint sealing technology, as a weak point of building thermal insulation, its thermal conductivity (K value) is rarely lower than 2W/m2K. An external wall with good thermal insulation has a thermal conductivity of only about 0.5W/m2K, that is to say, the heat loss through a thermal insulation glass window is almost 7 times that of the external wall.
A properly installed outer roller blind in front of a window or door can reduce the heat loss through the window by more than 40%. In order to maximize the thermal insulation efficiency, the shutter window must be installed on the outside of the window, while ensuring that there is an air layer between the glass window and the shutter window. In order to obtain the ideal thermal insulation effect, the use of external shading roller shutter window should pay attention to the following points:
1. Closure of roller shutter plate;
2. The tightness of the contact part between the roller shutter plate and the roller shutter cover;
3. Tightness of guide rail;
4. The tightness of the combination of the guide rail and the wall;
5. Closure of rolling window seat and window sill;
6. The thermal insulation performance of the roller shutter cover.
2. sound insulation performance
Usually people want to have a quiet room, especially near the street, road room. The use of fully closed, mounted on the outside of the glass window outside the sun shutter window can greatly improve the sound insulation effect of the window. Through research, it is found that the greater the distance between the shutter window and the glass window, the better the noise reduction effect. The closed rolling window itself can reduce the noise by 18dB. If it is combined with the insulation glass window (4/12/4mm), a comprehensive sound insulation effect of 37dB can be obtained.
3. sun protection performance
In winter, people hope to warm their rooms through the sunshine through the glass windows, but the scorching sun in summer is the last thing people want. At this time, only a small part of the light is reflected by the glass windows, and most of it is shot through the glass to the room. Therefore, people put forward the requirement of sun protection. Although there are various sunshade and sunscreen methods, the external sunshade roller shutter window installed outside the glass window is one of the most ideal solutions to this problem, because first, the external sunshade roller shutter window can reflect most of the sunlight. Second, the external sunshade roller shutter window can also steplessly adjust the sunlight entering the room; third, its use basically does not occupy space. By reducing the amount of heat entering the room, one can save a lot of electrical energy for the air conditioner.
If you choose a light-colored roller shutter profile, you will be able to better improve the reflection of sunlight.
4. weather resistance
The outer sunshade rolling window has the ability to resist wind, rain and snow and sand. A protective barrier was added to the doors and windows of the building.
5. anti-theft performance
The outer sunshade rolling window is also a beautiful protective device. The completely closed rolling window can prevent the glass window from being damaged by bricks and balls, and can also prevent the invasion of thieves. In terms of anti-theft, taking certain measures will greatly improve the anti-theft performance of rolling shutters, such:
1. Reinforced roller shutter surface materials, such as double-layer steel filled polyurethane profiles, double-layer aluminum alloy profiles filled with super-hard polyurethane, etc;
2, the use of reinforced guide rail, increase the depth of the guide rail;
3. Strengthen the connection reliability of each fixed part;
4. Adopt locking or anti-pushing mechanism;
5. Adopt the form of concealed installation on the building (that is, roller shutter guide rail and cover are placed inside the wall)
