The real energy-saving doors and windows, not a single use of partition bridge aluminum profiles or Low-E hollow glass energy-saving materials, it is a perfect combination of the system, the comprehensive results of each link performance, indispensable, to measure the energy conservation of building doors and windows should mainly consider three elements, namely, heat loss (heat exchange), heat convection and heat conduction and radiation; 1. Convection is the circulating flow of hot and cold ai......
Sound Insulation SexWooden door is processed by whole solid wood and become, so its density is high, door plate massiness is heavy, also because of this so wood door has good sound-absorbing sex, can effectively play the role of sound insulation.Aluminum alloy door window basically is formed by aluminum profile structure, glass structure and hardware fittings structure, the sealing requirement when 3 people join is taller, thickness is not enough, jail-cut, sealing quality does not reach the sta......
Aluminum alloy is the most economical and reasonable for building structure. the higher the purity of aluminum is, the lower the strength is, so scientists added other elements to aluminum and invented aluminum alloy to enhance its physical and mechanical properties. Aluminum is rustproof, with a good appearance, and the life of aluminum alloy is the longest. However, aluminum alloy must also be carefully selected, choose a brand of good quality, and there is also a guarantee after sale. If it i......
In the selection and purchase of windows, in addition to the size and style of the windows, we usually pay more attention to the materials of the windows. Even many friends may ask: what kind of window is better? Let's talk about the advantages and disadvantages of windows of different materials, and then we can compare the decoration style of the building, the location of installation and so on to determine which kind of window is more suitable for you. 1. Wooden window: a window made of wooden......
The aluminum window in the balcony position is generally drenched in the sun and rain, of course, it is very easy to oxidize and fade, but if you choose a good spraying process, the chance of fading will be very small. Generally speaking, the quality of aluminum windows and doors?is much better than that of plastic steel windows and doors. The fading of plastic steel is inevitable, the material of plastic steel itself is good, but it is necessary to fade for a long time, to aging, this can not ......
1, Heat Insulation Performance: Its performance is quite good, if the installation is this kind of Windows and doors, then in the summer, the temperature of the house must be lower than the outside of the house, living up is also more comfortable. And in the winter, it stops the heat from escaping.2, Waterproof Performance: Because of its pressure balance, and in the production, the slope control is also better, so do not have to worry about water will accumulate in, the speed of drainage is cer......
Broken bridge aluminum windows?and doors, as the most mainstream windows?and doors?products, has become a widely accepted material for windows?and doors, so how long can they be used? How long is its life? in Germany, we can still see windows?and doors?that have not been changed for 50 years, so how long do the current broken bridge aluminum windows?and doors?last? There are two keys that affect the service life of broken bridge aluminum windows?and doors: one is the quality of aluminum......
As for broken bridge aluminum windows?and doors?or aluminum alloy windows?and doors, people have different opinions. Well, today I would like to analyze for you that there are four main differences between broken bridge aluminum windows?and doors?and aluminum alloy windows?and doors. The details are as follows1. There are some differences in thermal insulation. Aluminum alloy windows?and doors?are not insulated, especially in summer, the surface of aluminum alloy will be very hot under t......
Wood-aluminum doors and windows are very popular nowadays, compared with other doors and windows, aluminum windows and doors can be described as the "aristocracy" of doors and windows. So, what is the difference between wooden aluminum doors and windows and other doors and windows? Why are you so "aristocratic"?1.Energy-saving type (thermal insulation). There is a professional term in the world of doors and windows: heat transfer coefficient K value (also known as conductivity coefficient or ins......
Wooden window, made of wood, has strong water absorption, difficult to switch on rainy days, big cracks in winter, poor sealing, and easy to decay. Now wooden windows are rarely used, and wooden doors are still used by many people. The type of wood determines its price. Aluminum-wood composite doors and windows are made of aluminum alloy, which combines internal and external aluminum alloy through thermal insulation strips to achieve thermal insulation performance, which can not only meet the ne......
Anti-wind pressure strength and water?tightness: Due to the low material strength and steel, plastic steel windows?and door?are strengthened by lining, but their wind pressure resistance and water?tightness are about two grades lower than those of aluminum alloy windows?and door. The standard sample window submitted by the enterprise for inspection is like this, and so is the sampling at the construction site. The average value of "three properties" of aluminum alloy windows?and door?and ......
Aluminum alloy?windows?and doors, refers to the use of aluminum alloy extruded profiles as frames, mullions, fans for the production of windows?and doors?called aluminum alloy windows?and doors?referred to as aluminum windows?and doors.?Aluminum alloy windows?and doors?include aluminum alloy as stress members (members that bear and transfer dead weight and load) and wood-plastic composite windows?and doors, referred to as aluminum-wood composite windows?and doors, aluminum-plastic co......
