aluminum windows manufacturer 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. You can't miss it. 1. Sealing strip There will be a ring of sealing rings around the doors and windows. The sealing rings are generally rubber, with good elasticity and toughness, and play a sealing role. They can also play a certain buffer effect on the door and window accessories. The seals are bright in color, uniform in thickness, moderate in hardness, and can be used for three or four years, and they will be broken after a year and a half of poor quality. 2. Sound insulation strip There will be a certain gap between the door and the floor, and a small gap has a greater impact on the sound insulation of the door. In fact, the bottom of the door can be nailed with a sound insulation layer, some made of fiber cloth, and some made of plastic brush. The sound insulation material is thin, but it is enough to fill the gap and will not affect the opening and closing of the door. 3. Track rubber strip The sliding doors and sliding windows are embedded in the track or frame, and the window frame and the outer frame are made of metal. Even if the doors and windows are closed tightly, there is still a certain gap between the two. Good doors and windows have a layer of rubber strips on the frame and track, which can play a sealing role and prevent the doors and windows from falling off. Of course, there is no sharp metal friction when opening and closing doors and windows. 4. Cushion pad We used too much force when opening doors or sliding windows. When the doors and windows hit the door frame or window frame, there would be "vibration or noise". A long time learning will affect the life of the doors and windows, and may even shatter the glass . An important cushion rubber pad can be installed at the corner of the frame of the door and window system to reduce the effort of enterprise cushion management. 5. Rubber cap for drainage hole The lower layer of the door and window frame is provided with multiple drainage holes to facilitate the drainage of rainwater accumulated on the frame track. 6. Glass layering After the door and window glass is installed, the glass rod should be sealed once. In addition to increasing the seal, it is more important to increase the firmness of the glass to avoid falling off due to strong wind or other external forces. Most of the glass rods are rubber strips, but some will be replaced by silica gel. Although silica gel can be sealed, it is easy to fall off in the sun for a long time. awning windows vs sliding windows how to make external bifold doors how much is a sliding glass door cost farmhouse front door with privacy glass
