First, clarify the needs and budget. Before starting to replace doors and Windows, think carefully about your own actual needs. If you live in a noisy street, the sound insulation performance must be the first consideration, you need to choose double or multi-layer insulating glass, sealing rubber strip quality door and window products; If the house is located on a high floor, strong wind and pressure resistance doors and Windows are indispensable. At the same time, in combination with the family economic situation to develop a reasonable budget, avoid blindly pursuing high-end and overspending, but also to prevent cheap choice of poor quality products, resulting in frequent follow-up maintenance.
Second, material selection is the key second point. Today, there are a variety of door and window materials on the market, common aluminum alloy, plastic steel, broken bridge aluminum and solid wood. Aluminum alloy is durable, not easy to deformation, suitable for a variety of climate environment; The thermal insulation performance of plastic steel is excellent, the price is relatively close to the people, but the strength is slightly inferior; The comprehensive performance of broken bridge aluminum is superior, both heat and sound insulation and high strength, but the cost is high; Solid wood doors and Windows have warm texture, natural environmental protection, but they need to be carefully maintained to prevent moisture deformation. Choose the most suitable material according to the needs, budget and climate of the area.
Third, dimensional accurate measurement can not be ignored. Even if the quality of the doors and Windows is superior, if the size is not suitable, there will be problems after installation, such as air leakage, rain leakage and even unable to switch normally. Professional surveying personnel should come to the door twice, the first preliminary measurement, and then review after the completion of the basic works such as walls and floors to ensure that the data is accurate to millimeters. When measuring, we should consider the installation position of the doors and Windows, the connection with the surrounding wall, and reserve enough installation space.
Fourth, the installation process directly determines the final use of doors and Windows, which is the fourth point. Hiring an experienced and skilled installation team is critical. They are familiar with the installation process of all kinds of doors and Windows, and can properly handle the key links such as sealing, waterproof and fixing. During the installation process, it is necessary to supervise the use of high-quality sealant, expansion bolts and other accessories to ensure that the doors and Windows are firmly installed and sealed, and effectively prevent wind and rain invasion and noise introduction.
Fifth, after-sales protection is often overlooked but very important. Doors and Windows in the use of the process will inevitably appear hardware wear, sealant aging and other problems, quality brands usually provide several years of warranty service, after-sales response in a timely manner, can quickly solve the fault. Be sure to understand the merchant's after-sales terms before purchase, ask for warranty vouchers, and eat "reassurance" for future use.
The replacement of doors and Windows firmly grasp these five key points, from the demand budget, material selection, size measurement, installation control to after-sales protection one by one, you can make the new doors and Windows perfect into the home environment, add color to life, open a comfortable and secure day.
