Many people living in tier building are preferring to choose thermal break aluminum casement windows when replacing windows. This kind of window has a larger opening, better ventilation, sealing and thermal insulation. However, people who live in high-rise building (7th floor or above) are not recommended if they want to choose a thermally broken casement window with outer opening method. A responsible window sales will tell you some restrictions on the national standard of architectural windows. For residents living in the high-rise floors, if you plan to replace window, please choose sliding window.

National Regulations:

In residential buildings, 1-3 layers are low-rise, 4-6 floors are multi-layer, 7-9 floors are middle and high-rise, 10 floors are high-rise, and over 100 meters are super high-rise. According to the regulations, 7 floors and above are not allowed to install casement window with outer openning method.

High-rise building windows must consider its safety and wind pressure resistance. The reason why the high-rise buildings must choose to sliding window is because the outer-opening casement window has the danger of falling down of the window sash, and when the weather is high windy, the high-rise building glazing of being blown off by the wind is not uncommon every year, even if the window with the best quality and installed correctly. This not only causes inconvenience to the life of the high-rise tenants, but once the fallen window sash hurts others, the consequences are unimaginable. And this happens every year.

In addition, the high-rise community generally emphasizes the overall sense of the building’s shape, so the facade is generally required to be consistent. So the sliding window is the first and best choice for different layers.

UPVC or ALUMINIUM For Sliding Window?

The sliding window in the market is mainly divided into plastic UPVC sliding window and aluminum alloy sliding window. Plastic UPVC sliding windows are economical and practical, occupying most of the market, but some defects in their own make more people choose aluminum alloy materials when replacing windows. Ordinary plastic UPVC sliding windows generally find one thing.Everyone knows that when push and pull a plastic UPVC sliding window, it is easy to appear stuck. In fact, this is caused by sliding rails and pulleys. Because the hardness of plastic UPVC is not high, it is easy to generate friction when pushing and pulling. However, the aluminum alloy sliding window is selected with high-quality pulleys, and the sliding rail movement is specially researched and designed to customize the corresponding movement track, so that the window is pushed and pulled smoothly, and the problem of the stuck is not easy to occur. Due to the low hardness of plastic UPVC windows, it is easy to age and deform after a long period of use, which largely affects the performance of windows. Therefore, aluminum alloy material is a better choice.

What Series Do I Choose For Aluminum Sliding Window?

Aluminum alloy sliding windows are available in 55 series, 60 series, 70 series, 80 series, 90 series and so on. The selection of the series should be based on the size of the window and the local wind pressure. The aluminum alloy sliding window used in balcony should be no less than the 70 series. Many people do not understand 60, 70, 80 series aluminum alloy windows in the process of selecting doors and windows for home decoration. So what is the difference between them? How to choose a most suitable one for your home?

The difference between the 60, 70, and 80 series is the section of width of the profile, which is 60MM, 70MM, and 80MM. The wall thickness of the aluminum alloy profiles used is 1.4MM. Due to the different widths, the 80 series uses more aluminium alloy materials and has better wind pressure resistance, of course, the price is also more expensive. Comparing with 60 and 70 series windows, the 80 series window frame width is wider, which means that the 80 series has more free space than other series, the sealing strips and tops will be correspondingly thickened, and the window sash hollow glass (commonly 5MM+9MM+5MM), so the sound insulation effect is relatively good. However, the practice of selecting the window model is still a detailed analysis of the detailed problems, and comprehensive consideration of its own balcony area. The larger the model, the larger the area of the window sill.

In general, the functions of the 60, 70, and 80 series windows are the same, and there is no good or bad, just choose the most suitable one for your home will be fine. In the process of selecting the window, not only consider the anti-wind pressure and safety performance, but also the price and window sill area.

How To Check The Quality of An Aluminium Sliding Window?

▹Aluminium Profile Section

You can ask the window sales to display the section of the aluminium frame profile to understand the material and structure.

▹Pulley Movement

The skating of the balcony sliding window is very important. The good skating structure is relatively complicated. The inner bearing has an aluminum block to fix the two wheels, so that the orientation is smoothly slid and there is no noise. Generally, high-quality sliding windows should have a certain weight when sliding, smooth and without vibration.

▹Safety Glass

The national standard suggest tempered glass for architectural windows. Tempered glass can be processed into single-layer glass, insulating glass, laminated glass, strength, impact resistance, excellent thermal insulation performance, and is a good choice for balcony glazing.
