Broken bridge aluminum windows + hollow glass K value of about 2.7-3.0;
Ordinary aluminum doors and windows + hollow glass K value of about 3.5-5.0;
System aluminum doors and windows + hollow glass K value of about 2.0-2.5;
5. What is safety glass? When to use safety glass?
After the glass is treated with high temperature, the quality has changed and the strength of the glass has been enhanced. Even if the glass breaks into small particles, it does not hurt.
In the following cases, aluminum alloy doors and windows must be made of safety glass: 1. Glass for floor spring door 2. Area of ​​glass for single window is more than 1.5m2, and area of ​​single glass for framed door is more than 0.5m2; 3.

Doors for kindergartens or other children's activities; 7. Tilted windows, sunroofs; open windows on floors 8, 7 and above.
6. What is LOW-E glass? What is its advantage?
LOW-E glass, also known as low-emissivity heat-reflective glass, is a layer of film coated on the surface of the glass to shield the outside from ultraviolet rays and increase or decrease the temperature inside and outside the room, which is a protective effect on the human body.
7. What is a hollow 100-page glass? What is the material of the sheet? What is the useful life?
In the hollow glass, aluminum foil is installed and controlled by magnetic force. It can be used 20,000 times for about 20 years. The advantages are cleanliness, hygiene and no cleaning.
8. What are the advantages and disadvantages of insulating glass, LOW-E glass and hollow louvered glass?
Insulating glass is good for energy saving; LOW-E glass is UV resistant; hollow 100-sheet glass is convenient, direct sunlight is prevented, and privacy is increased.
9. What is the wall thickness of the aluminum alloy window profile? What is the wall thickness of the aluminum alloy door profile?
The wall thickness of the main section of the window profile shall not be less than 1.4mm, the upper layer shall be more than 20 layers, and the thickness of the profile may be increased; the wall thickness of the main profile of the door profile shall not be less than 2.0mm, which is the requirement of the national standard to meet the wind pressure resistance. Single doors and windows more than 3-4 square can be thickened, over-sized columns can be added.
10, what is the system door and window? Its origin?
The system doors and windows originated in Europe. Through many years of use, the airtightness and energy-saving effect of doors and windows were taken into consideration during design. The system doors and windows are adopted by the system company as a solution to the overall door and window system and make a clear commitment to the performance and quality indicators of the product. Watertightness, airtightness, wind pressure, mechanical strength, heat insulation, sound insulation, security, and sunshading need to be considered. A series of important functions such as weatherability, handling, etc., also consider the comprehensive results of the performance of the equipment, profiles, accessories, glass, viscose, and seals.
11. What is the warranty period for insulating glass? What is the scope of the warranty and what is not covered by the warranty?
The national standard for the warranty period of insulating glass is 15 years; the service life is 15-20 years, and there are examples in Europe.
If glass is broken due to improper use of human factors, it is not covered by the warranty.
12, what is the heat transfer coefficient? What is the ordinary aluminum alloy door and window heat transfer coefficient? What is the heat transfer coefficient of broken aluminum alloy doors and windows? What is the heat transfer coefficient of aluminum alloy doors and windows?
It is during the test that internal heating takes time to look at the speed at which the internal temperature is conducted outward, and the heat transfer value is obtained at the passing time and temperature.
Ordinary aluminum alloy doors and windows heat transfer coefficient of about 3.5-5.0;
Broken bridge aluminum alloy doors and windows heat transfer coefficient of about 2.5-3.0;
The heat transfer coefficient of aluminum alloy doors and windows is about 2.0-2.5.
13. What is a sliding window? What is a flat door? What is the top window? What is inside the window? What is a fixed window?
