narrow bifold closet doors curtains for double sliding glass doors what is mesh door? aluminium sliding door manufacturers melbourne Frequently used, different consumers will consult, what is the difference and difference between plastic steel doors and windows and doors and windows, we need to talk about it in the article before, and we will not talk about it today. Whether it is the difference in learning materials, it is mainly a heat insulation. There are differences in sound insulation, heat preservation and sealing. The key content of today's development tells what is the difference between the sound insulation and sealing problems of plastic steel doors and windows than doors and windows? 1. Sound insulation: Why is the sound insulation of plastic steel doors and windows not as good as doors and windows? Because the performance of the sealing system of plastic steel doors and windows is not as good as that of doors and windows, and the sealing treatment is not good, naturally the sound insulation will be worse than that of doors and windows. Aluminum alloy doors and windows The doors and windows made of aluminum alloy extruded profiles as frames, stiles and fans are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include wood and plastic composite doors and windows that use aluminum alloy as the base material of the force-bearing member (the rod that bears and transfers its own weight and load), referred to as aluminum-wood composite doors and windows, and aluminum-plastic composite doors and windows. The perfect organic combination of a performance system for system doors and windows requires consideration of a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, and operating feel. Considering the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals, all of them are indispensable, and finally high-performance system doors and windows are formed. Broken bridge aluminum doors and windows use thermally insulated broken bridge aluminum profiles and hollow glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof. 2. Airtightness: Plastic steel is worse than doors and windows for sealing. We don't need to talk about it. Why is it so? Because plastic-steel doors and windows are equipped with rubber strips on the window frames, and you can install a buckle after installing a glass. This method of fastening strips with adhesive strips is much worse than applying glass glue between windows and glass companies. When doors and windows are installed, people inside and outside the window and the glass company must apply glue. The second analysis is the difference between the rubber strips on some windows. Take the casement window of plastic steel door and window as an example. The plastic steel casement window mechanism has at most two rubber strips, and the most common 55 series of door and window systems also have problems. Three rubber strips, better door and window design, and ten sealing product series to improve the sealing effect layer by layer, so they can see if the plastic steel door and window project is much worse than the door and window in the sealing performance.
