There are two major factors to consider when it comes to whether you are suitable or not.
Surrounding environment and policies and regulations
1) Environmental factors
The largest environmental impact around should be regional differences, the temperature difference between the north and the south is large, the north focuses on thermal insulation and air tightness, and some areas in the south have more rainwater, so more attention is paid to water tightness, that is, waterproof performance. For example, in some areas, there is more wind and sand, and the requirements for air tightness are higher.
In addition to the impact of the general environment on people, more is the impact of the surrounding small environment, such as the floor height of the residence, whether it is located near the downtown area, whether there is a traffic main road, the rain and wind level of the city, whether there is an anti-theft demand, and even whether there is a square dance troupe around.
These influencing factors are actually considered around thermal insulation performance, sound insulation performance, wind pressure resistance, water tightness, and air tightness.
2) Policies and regulations
After considering the environmental aspects, it is also necessary to pay attention to the impact of local policies and regulations.
In the guidelines of the National Technical Measures for Civil Construction Engineering Design 2009 Planning, Architecture and Landscape, this is the case
Multi-storey residential buildings (less than or equal to 6 floors) often use outward casement or sliding windows; High-rise buildings should not have casement windows. When using sliding windows or external windows, there should be measures to strengthen the sash and prevent falling off.
In the General Principles for the Design of Civil Buildings GB 50352-2005, the definition of high-rise buildings is as follows
1~3 floors are low-rise, 4~6 floors are multi-storey, 7~9 floors are medium and high-rise, and 10 floors and above are high-rise residences
It should be noted that different regions and even different communities have different regulations for window installation, and the specific plan given by the local should be referred to.
To judge whether casement windows or sliding windows are suitable for themselves, it is necessary to combine the above influencing factors to judge their different demand ratios for thermal insulation performance, sound insulation performance, wind pressure resistance, water tightness, and air tightness, so as to choose the type of aluminum alloy window.
