The doors and windows of my home were made by a shop at the door of the community. It has been used for five years. Now I can only shake my head and sigh. The window leaks and can't be pushed at the same time

Xiaobian believes that the current situation of the door and window market shows that the product quality is uneven. Most of the low-quality aluminum alloy doors and windows blindly choose aluminum profile series and specifications, and the processing is rough. They use sawing instead of milling, and do not install as required. The sealing performance is poor, and the doors and windows cannot be opened and closed freely. Not only do they leak air and rain, and the glass bursts, but also encounter strong winds and external forces, It is easy to scrape or bump the sliding part or glass. The doors and windows of Xiaobian's friend's house were made by a shop at the door of the community. It has been used for five years. Now I can only shake my head and sigh. The window leaks and can't be pushed at the same time

first of all, the doors and windows of the system must be high-quality and high-performance doors and windows, which are the perfect combination of all performance systems. It is not only necessary to consider a series of important functions, such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, theft prevention, sun shading, weather resistance, operating feel, but also the comprehensive factors of the performance of equipment, profiles, accessories, glass, viscose, seals, auxiliary accessories and supporting screens, All of them are indispensable. With the technical support of the system and the after-sales service of the system, high-performance system doors and windows will finally be formed

the purpose of selecting system doors and windows

1. Protect the health of residents by creating a healthy and comfortable environment

2. Protect the building structure and decoration structure from the damage of condensate or rainwater naturally occurring in the air

3. Reduce the energy consumption of heating and air conditioning

4. Reduce maintenance and operation costs

are the system doors and windows expensive

take the product price of youzhiya door and window brand as an example. The price of system doors and windows ranges from 850 yuan/square to 1400 yuan/square, and the price of ordinary doors and windows ranges from 350 yuan/square to 800 yuan/square. Its price is only about 500 yuan to 600 yuan per square meter higher than that of high-quality ordinary doors and windows

energy saving analysis of system doors and windows

for the house type with an area of less than 120 ㎡, the window area is about 30 ㎡. Take the 24kw boiler as an example, and open it for 30 days, including domestic water. The boiler is used for 6 hours every day, and the rest of the time is in the thermal insulation standby state. The system doors and windows save 30% energy consumption compared with ordinary doors and windows (60% energy saving after glass upgrading)

conditions:

1. Open the floor heating with ordinary doors and windows every day, and the consumption of gas is 2.6 cubic meters

2. Open the floor heating with system doors and windows every day, and the consumption of gas is 1.8 cubic meters

3. The gas fee is calculated at 4.6 yuan/cubic meter (the highest price of the gas ladder in Hangzhou at present). System windows are 1490 yuan/month, and ordinary doors and windows are 2152 yuan/month. (gas consumption × 30 (days) × 6 (hours) × 4.6 yuan)

cost savings from annual heating: (2152-1490) × 4 = 2648 yuan. (ground heating for 4 months a year)

cost difference of doors and windows: cost of system doors and windows - cost of ordinary doors and windows = 42000 - 24000 =18000 yuan

therefore, 18000 ÷ 2648 ≈ 6.8 years is calculated

the general design life of buildings and residences is 70 years, and we can recover the excess cost of architectural windows in only 7 years ~
