More than number of screens naturally use a lot of profiles, the track is literal meaning, two rails or three rails, sliding door necessary. Three rails is larger than double track push-pull in opening area! But aluminum alloy usage is large!
The three doors of three rails can open one piece, and the three doors of two tracks can only open one door. The opening area of double-track profiles can reach up to 50%, and three rails profiles can reach 66%! This is the main difference! Other differences include stability, number of Open fans, and aesthetics! According to the balcony area, the open space is different. Three doors of three rails can open one piece, and three doors of two tracks can only open one door.
Three rails sliding window has these three advantages:
Advantage 1
Three rails sliding window compared with ordinary dual-track sliding window, the difference is on the track. Three rails is suitable for three or more windows. It can overlap all Casement on one Casement through slide rails, so that two thirds of the space can be opened at once, in this way, better ventilation conditions can be obtained indoors to ensure smooth circulation of indoor air.
Advantage 2
Because it is three tracks, the upper and lower two sets of pulleys play a guiding role, in which the internal bearings and aluminum blocks can make the pulleys slide stably, and the opening or closing are smooth and silent, without noise, and the switch is convenient.
Advantage 3
The sliding door of the three tracks has good sealing performance, and it is difficult for dust and moisture to enter the room, and the sound insulation and heat insulation effect are very good.
But as a decoration and material selection Xiao Bai, I don't know how to choose a good quality three track sliding window? Fortunately, my friend was kind enough and patiently told me three things to pay attention to when buying it:
The first and most important thing is quality. The material of three track sliding window on the market is made of aluminum alloy (aluminum magnesium) or recycled aluminum. You must choose aluminum alloy (aluminum magnesium) material with a thickness of 1.4mm. When purchasing, you need to check the cross section and sample of the material. If it is found to be coated, it is the commercial household recycled aluminum that is painted with color to deceive consumers!
Secondly, when purchasing three rails sliding window, you must choose a track with positioning function, so that there will be no gap when closing, preventing dust and moisture from entering the room; the surface of the track is better to choose the shape of the flat plate, so it is much easier to clean up in the future, and there is no need to worry about hiding dirt.
Finally, in the choice of window glass, it is better to choose tempered glass with good quality, which can ensure the safety of windows and family members. Even if it breaks when using, it will not hurt people and has a high safety factor.
After listening, according to the purchase method mentioned by my friend, I finally chose three rails sliding window. I don't know if everyone knows three rails sliding window?
What are the disadvantages of three sliding door fans? Our family has been using sliding door for a long time. Personally, I think there are the following problems:
1. Sliding door mainly uses pulleys and tracks, and the friction and loss during pulling are very large.
2. Although it is beautiful, the sealing is not very good.
3. From the perspective of cleaning and sanitation, sliding door need to install long tracks on the ground, which is easy to accumulate garbage and sundries and is not easy to take care of for a long time.
Disadvantages of triple sliding door:
1. The price is relatively expensive, and the cost is mainly on hardware. Wall cupboard doors have high requirements on track hardware. For example, the price of rail doors with super house frame in my home is about 1200/square meters on the market, however, the two fans bought on Taobao at I am have a total of 6,000 (excluding installation) and need to have sufficient control over the size and workmanship. If you are not professional, don't try it easily, if it is finished, it will be troublesome if it cannot be installed.
2. The tightness is not as good as that of the track door, because the ceiling door does not touch the ground and there will be gaps, which will affect the air conditioning effect but not very large.
3. High construction technology requirements.
4. The service life and maintenance comfort level are not as good as the track door. The rail door is not completely unserviceable, but relatively troublesome. I saw someone saying that the hanging rail door would shake, in fact, it was because there was a roller on the ground that limited shaking was not installed properly. After installation, the shaking will be greatly reduced.
5. The effect of constant temperature is relatively bad, but its overall performance is relatively reliable.
6. The quality of pulley and slide rail is unreliable, and problems such as deformation of door panel, poor push and pull, and severe noise occur from time to time.
