The quality of doors and windows directly affects the safety of the house. In recent years, more and more brands of aluminum alloy doors and windows have led to uneven quality of doors and windows. How to choose high-quality aluminum alloy doors and windows is a bit confusing for consumers who are not knowledgeable. How to distinguish the pros and cons of aluminum alloy doors and windows? Look clearly at these six points and don't be afraid of getting into the pit.
1. Aluminum material Aluminum material is equivalent to the human skeleton. The aluminum material is used to distinguish the quality of doors and windows. 1. It depends on whether the profile is made of virgin material or recycled material. 2. It depends on the frame width and wall thickness of the profile. Good quality doors and windows They are all processed with virgin aluminum. The load-bearing wall thickness of the profile is above 80 series. The surface of the good profile looks brighter. 2. Why is the insulation strip called broken bridge aluminum doors and windows? It uses insulation strips to separate the profiles. The small but very effective insulation strip is equivalent to the bone connecting the bones and the bones. It connects the two aluminum materials inside and outside. , Here is a non-broken bridge, the heat insulation strips on the market are generally nylon pa66, pvc material is easy to crack in the wind and sun, and PA66 is resistant to high temperatures of 300 degrees, so it is obvious whether it is good or bad.
3. Glass The largest window area is not the profile, but the glass. Therefore, whether the window is energy-saving and safe is the glass. The glass should be selected according to the size of the window and the appropriate thickness. The glass and the hollow layer of the glass must be at least 12a or more. There must be a 3C certification mark. The aluminum strip between the glass and the glass must be filled with molecular sieve. The aluminum strip must be bent in one piece, and the lap type must not be selected. The hollow layer of the glass must be filled with a press. 4. Hardware windows are not safe to use or not. Hardware is very important. Hardware is also called the heart of the door and window system. It can be divided into closing parts, load-bearing parts, operating parts, and auxiliary parts. Through the collocation and integration of the system, it serves Subsystem of door and window system. No matter how good the window is, if the hardware is not good, it will affect the sealing, thermal insulation and even basic safety. High-quality doors and windows must have a perfect hardware system.
Five. Adhesive strips It is the key to ensure the airtightness of doors and windows. EPDM rubber strips must be used. Excessive manufacturers use inferior recycled rubber strips to reduce costs, which will seriously affect the life and quality of doors and windows. High-quality rubber strips are calculated by the meter. , And the inferior quality is calculated by ton, the price of this kind of rubber strip is two or three times different, and the high-quality rubber strip has less harmful ingredients. Six. Glassglue If you want windows to last longer, use good glass glue. Big brands will make a scientific ratio based on the performance of each link to reduce shortcomings. And a high-quality system door and window must have the above points, each part of the error will affect the door and window
