The Purchase of Aluminum Alloy Doors and Windows Must Be Accurate to These Four Characteristics So That They Will Not Suffer Losses.

Many users often take a fancy to the price when purchasing aluminum alloy doors and windows. If the price can be felt good, but: However, the performance of aluminum alloy doors and windows also affects the service life and purchase price, so what basic characteristics must we know when choosing aluminum alloy doors and windows? I. Sealing design Sealing design the sealing of unit doors and windows is relatively critical, the main structure of the seal is that the cell and protection box between the unit and the protective frame seal and the protective frame rack and between cells should use the seal between two or more seals and between the holes continuous rubber seal; different structures according to the form of a target design should be carried out between the protective frame frame of the seal structure design and the said hole, make the protection between frames and usually keep the independent entrance waterproof mortar hole sealing treatment after use, you can use waterproof silicone protective frame and then seal the window opening between the interior and exterior finishes. II. Waterproof design Waterproof design is a highlight of doors and windows. You can make waterproof modular design and double waterproof design on the doors. The waterproof design of the equipment itself, the doors and windows on the second floor of the shielding box, according to the setting of drainage holes and units, in addition to protection, the drain hole is also opened at the location where the next frame is connected to the unit body. Rainwater or condensed water is directly discharged from the drainage outlet to the body under normal conditions. If the cell body and the protective box between the cell body and the rainwater infiltration or leakage seal caused by the poor internal drainage of the unit body and the condensate of the cavity profile are not tightly sealed, it can pass through the second layer which is smoothly discharged by waterproof protective case. III. Energy saving design Not only protective box, bridge thermal profile window unit (wear bar or distribution type can be used), insulation structure width 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 elastic insulation material (extruded polystyrene material or polyurethane material), it can effectively hinder the internal air circulation of the cavity of the splicing unit, and the energy-saving effect is far more than other similar energy-saving windows, and it also has the effects of sound insulation and noise reduction. IV. Seismic design Unit doors and windows a special plug-in installation suitable structure enhances the displacement capacity of the main structure of the window, which can effectively absorb earthquake, temperature changes, interlayer displacement, it is more suitable for earthquake resistance requirements in different regions than traditional doors.
