Nowadays, most people want to purchase high quality Windows. They pay more attention to the quality of Windows accessories, such as the profiles, glass, hardwares. They think the windows will be high performance if all the accessories are good. White high quality doors and Windows ≠ high-performance doors and Windows. Then what is the standard of high performance windows.
The real system door and window is a perfect organic combination of performance system, which needs to consider a series of important aspects such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance and operation feel. The function, but also consider the comprehensive results of the performance of equipment, profiles, accessories, glass, adhesives, seals, all indispensable, and ultimately form high-performance system doors and windows.
What is the main purpose of using the system windows?
Protect the health of the occupants by creating a healthy and comfortable environment;
2. Protect the building structure and decoration structure from condensed water or rainwater naturally occurring in the air;
3. Reduce the energy consumption of heating and air conditioning;
4. Reduce maintenance and operating costs.
Let’s calculate the relevant data:
Example: 100m2 two-bedroom, the window area is about 30m2. System door and window insulation performance is better than ordinary doors and windows.
1. Turn on the air conditioner every day with ordinary doors and windows, and the power consumption is 30°.
2. Use the system door and window to open the air conditioner every day, and the power consumption is 25°.
3. The electricity fee is calculated at 1 yuan/hour. System window 1200 yuan / square meter, ordinary doors and windows 800 yuan / square meter.
The cost of air conditioning is reduced every year: (30°-25°)*365*1=1825 yuan.
Door and window cost difference: system door and window cost – ordinary door and window cost = 30 * 1200 -30 * 800 = 12,000 yuan.
Thus, the calculation is 12000 ÷ 1825 ≈ 6.5 years!
The general design life of a building is 70 years. We can recover the cost of building windows in only 6 years. The system doors and windows make the building energy-saving and efficiency increase for 64 years!
