[China Glass Net] Doors and windows are divided into envelope members or partition members according to their location. Different design requirements have the functions of heat preservation, heat insulation, sound insulation, waterproof and fire prevention. The new requirements are energy saving and cold. The heat lost in the area by the gap between the doors and windows accounts for about 25% of the total heating consumption. The requirements for the tightness of doors and windows are an important part of energy-saving design. Doors and windows are an important part of the building envelope system. The installation of doors and windows seems to be a simple job in the home decoration. In fact, it is not as simple as imagined.

Door and window frame overall stiffness difference
Phenomenon: Pushing or opening or closing doors and windows or encountering windy weather, the door and window frame shaking.
Reasons: 1. The profile is not properly selected, the section is small, and the strength is not enough. The prevention of aluminum alloy door and window materials does not meet the requirements. The quality of plastic steel door and window materials is unqualified.
2. The steel lining steel of the steel doors and windows does not meet the standard. (General steel lining should use 1.20, but it cannot be seen by the owner because of the installation. Many merchants use unqualified installation for the owner.) The steel wall is thin and the strength is poor. The lining steel is inserted in sections, and the shape does not form an integral strengthening effect; the lining steel and the plastic profile are not firmly connected.
3. The installation node is not in accordance with the specifications.
4. There is no different fixing method according to different walls.
Measures: 1. The specifications and quantity of door and window frame profiles conform to national standards. The outer frame wall thickness of the aluminum alloy profile shall not be less than 2.4 mm. The thickness of plastic window material shall not be less than 2.5 mm.
2. Check the appearance of plastic profiles. The qualified profiles should be blue-white or ivory white, clean and smooth. A good quality film should be provided.
3. According to the size of the door and window opening and the installation height, select the section of the profile. The casement window is not less than 55 series, and the sliding window is not less than 75 series.
4. Strictly install according to the regulations to ensure firm and stable.
Door and window leakage problem
Phenomenon: 1. Leakage of the door and window frame and the surrounding wall.
2. The sliding window slid into the trough and penetrates into the window.
Reasons: 1. The door and window frame and the wall are caulked with cement mortar.
2, the glue between the door and window frame and the wall is not strict, there are gaps.
3. The door and window process is unqualified, and the combination between the window frame and the window sash is not strict.
4. The installation of the sash seal is unqualified, and the water penetrates into the glass sash of the window sash.
5. There is no drainage hole in the window frame.
Measures: 1. Door and window frame and wall shall not be caulked with cement mortar. It should be elastically connected and sealed with a sealant without gaps.
2. Check whether the doors and windows are qualified before installation, whether the combination between the window frame and the window sash is strict, and whether the sash seal is installed.
3. The gap between the window frame and the hole is more than 50 mm, so that the window sill can be used as a running water slope.
4. Drain holes should be drilled in the lower frame of the outer frame and the root of the track.
Door and window color difference is obvious
Phenomenon: Adjacent doors and windows or window frames do not match the fan color.
Reason: Materials are not the same factory product, or the same batch of products, or products of different material grades.
Measures: 1. The purchased products should be made of the same manufacturer and be prepared at one time.
2. Pay attention to the color of the ingredients before cutting, and avoid the materials with large color difference on the same door and window.
Precautions when installing doors and windows
During the installation process, the horizontal and vertical alignment of the doors and windows should be supervised. The squeegee is filled between the window frame and the wall, and the inner and outer sides of the window frame must be sealed with silicone copper or sealant to prevent water seepage. After the installation is completed, the protective film must be removed, otherwise the life of the doors and windows will be reduced. It should also be noted that after installing the window sash, check whether the amount of overlap of the window sash contained in the window frame meets the standard requirements. If there are quality and safety hazards, all must be reworked.
