The production of aluminum alloy doors and windows is through a series of strict tests, reaching the specified performance indicators before delivery and installation. What are the main properties of aluminum doors and windows?
1、 Sealing design
First of all, the sealing design of unit doors and windows is the most important. The main structure of sealing is the sealing between the unit and the protection frame, and between the cells and the protection box. The sealing between two or more seals and between the holes should be used for continuous rubber sealing; The protection frame of sealing structure design and the hole shall be designed according to a different structure in the form of a target design, so that the protection between the frames and usually should be kept independent of the entrance waterproof mortar sealing. The waterproof silica gel can be used to protect the frame and then seal the window opening between the internal and external finishes.
2、 Waterproof design
Waterproof design is one of the highlights of doors and windows. Modular waterproof design can be done in the door, double waterproof design, waterproof design of the equipment itself. In the second layer of the shielding box, according to the setting of drainage holes and units, in addition to protection, the drainage holes are also opened at the position where the main body of the unit is connected with the next frame. Rain water or condensed water is directly discharged from the drainage outlet to the body under normal conditions. If the cell body and the rain water seepage or leakage caused by the poor internal drainage of the unit body and the cavity profile condensate are not tightly sealed, the protection box can be discharged smoothly through the second layer of the waterproof protection box.
Third, energy saving design
The width of thermal insulation structure can be adjusted according to the requirements of energy saving target. Due to the unit door and window interface design and single cavity plug structure, the front door and window unit can be easily connected to one side of the elastic insulation material (extruded polystyrene material or polyurethane material), which can effectively block the air flow inside the cavity of the splicing unit. The energy-saving effect is far better than other similar energy-saving windows, and it also has the effect of sound insulation and noise reduction.
4、 Seismic design
The unit door and window is a special structure suitable for installation, which can enhance the displacement capacity of the main structure of the window, and can effectively absorb the earthquake action, temperature change and interlayer displacement. It is more suitable for the seismic requirements of different regions than the traditional door.
