How to choose aluminum alloy doors and windows?Learn about aluminum doors and windows in one article.
Introduction to door and window materials: In short, the material composition of doors and windows is: profiles, glass, hardware, window screens, and auxiliary materials: ① According to surface treatment, there are: powder spraying, fluorocarbon spraying, acrylic spraying, surface oxidation, surface electrophoresis, surface composite film (including wood grain), etc. ② According to energy-saving requirements, profiles are divided into: aluminum alloy windows can be mainly divided into ordinary aluminum alloy windows and broken bridge aluminum alloys. ③ Profiles are divided into width series according to the longitudinal width of the door and window frames. For example, if the longitudinal width of the window frame is 50mm, the window is called the 50 series. Speaking of broken bridge aluminum, are you confused if you are a novice in decoration? Don't worry, Huahua will discuss it with you! The "bridge" in the name of "broken bridge aluminum" refers to the "cold and hot bridge" in the sense of materials science, and the word "break" means action, that is, "break the cold and hot bridge". Specifically, because aluminum alloy is a metal and conducts heat quickly, when the indoor and outdoor temperatures differ greatly, aluminum alloy can become a "bridge" to transfer heat. Such materials are made into doors and windows, and their thermal insulation performance is not good. Broken bridge aluminum is to break the aluminum alloy in the middle, and it uses hard plastic to connect the broken aluminum alloy into one. We know that plastic conducts heat significantly slower than metal, so it is not easy for heat to pass through the entire material, and the thermal insulation performance of the material becomes better. This is the origin of the name "broken bridge aluminum (alloy)". Broken bridge aluminum alloy windows are improved windows launched on the basis of ordinary aluminum alloy windows to improve the thermal insulation performance of windows. The aluminum alloy profile is divided into two parts, inner and outer, by reinforcing nylon spacers. Partially blocks the heat conduction of aluminum. The thermal insulation of the broken bridge aluminum alloy window is excellent, which completely solves the problem of fast heat conduction and poor thermal insulation of ordinary aluminum alloy windows. Profiles Generally speaking, as long as the aluminum alloy doors and windows produced by regular aluminum alloy door and window manufacturers are made of high-quality aluminum ingots, they have good tensile strength and yield strength, and the thickness of the profiles strictly implements the "national standard" (reaching a wall thickness of 1.2mm) The wall thickness of the main profiles of aluminum alloy doors and windows should be determined by calculation or experiment. Except for the profiles that require elastic assembly such as pressure strips and buckles, the main stress-bearing parts of the main profiles for doors have a smaller cross-section of the substrate and the actual measured wall thickness should not be less than 1.6mm. The main stress-bearing parts of the main profiles for windows have a smaller cross-section of the substrate and the actual measured wall thickness should not be less than 1.2mm. The wall thickness of high-rise windows is required to be no less than 1.4mm, and the wall thickness of low-rise or multi-story windows is required to be no less than 1.2mm. However, the current profile wall thickness is above 1.4mm. The wall thickness of the door material is generally above 1.6mm, but some netizens may think that the kitchen door is lighter and easier to push, so they will choose 1.2 or 1.4 aluminum. However, if you want to install a balcony door, you need to resist wind pressure. It is recommended to choose a heavy sliding door, 1.6mm or more. The most common choice on the Internet is Fenglu, but Fenglu is generally used for windows. If you want to make sliding doors, you have to choose other brands of aluminum. Window thickness The size of aluminum alloy doors and windows x series refers to the width of the main frame of the aluminum alloy profile x centimeters! For example 70 series means the width of the main frame of the aluminum alloy profile is 70 cm. (But it must be said here that the width of the main frame here is different for each merchant, and the measurement location is also different. For example, some measure the bottom of the frame (Fuxuan Doors and Windows), some measure the side frame (Rongtang Doors and Windows), and some measure the width of the sash (Shengmilan Doors and Windows). This depends on how the merchant determines it. The model is also different for different merchants, but the most important thing for aluminum alloy windows is the thickness of the aluminum and the width of the main frame.) Aluminum alloy door and window size series There are two types of aluminum alloy sliding doors: 70 series and 90 series. The aluminum alloy sliding doors inside the house can use the 70 series. The basic door opening heights are 2100, 2400, 2700, and 3000mm, and the basic door opening widths are 1500, 1800, 2100, 2700, 3000, 3300, and 3600mm. The sliding aluminum alloy windows are 55 series, 60 series, 70 series, 80 series, 90 series, and 90-I series. The series selection should be based on the size of the window opening and the local wind pressure value. The aluminum alloy sliding window used for enclosed balconies should not be less than the 70 series. The basic window opening heights are 900, 1200, 1400, 1500, 1800, and 2100mm; The basic window opening widths are 1200, 1500, 1800, 2100, 2400, 2700, and 3000mm. Aluminum alloy casement doors include 50 series, 55 series, and 70 series. The basic door opening heights are 2100, 2400, and 2700mm, and the basic door opening widths are 800, 900, 1200, 1500, and 1800mm. Aluminum alloy casement windows include 40 series, 50 series, and 70 series. The basic window opening heights are 600, 900, 1200, 1400, 1500, 1800, and 2100mm; The basic window opening widths are 600, 900, 1200, 1500, 1800, and 2100mm.
