System door and window cost performance

In recent years, the building doors and Windows market is undergoing profound changes, the system doors and Windows are increasingly concerned by the people, and the system doors and Windows brand in the construction market continues to spring up. Most people think that the purchase of high-quality doors and Windows, pay attention to the obvious parts of the doors and Windows such as aluminum, glass, accessories and other quality can be, and some of the professional performance requirements of doors and Windows do not understand, more attention is the product quality, cost performance and other factors, the initial consumption ideology that high-quality doors and Windows is equal to high-performance doors and Windows.

High quality doors and Windows = high quality profile + glass + accessory strip + processing technology + installation technology +......

High-performance doors and Windows = high-performance profiles × glass × fittings strip × processing technology × installation technology ×......

Therefore: high-quality doors and Windows ≠ high-performance doors and Windows

The real system door and window is an organic combination of performance systems. The industry figuratively compares the difference between system Windows and ordinary Windows to "brand computers" and "assembled computers." System doors and Windows company is different from ordinary doors and Windows manufacturers, system doors and Windows company from the entire door and window industry chain, integration of all doors and Windows technology, materials and equipment, to provide downstream doors and Windows processing enterprises a series of system solutions, and to ensure the quality of the whole window. System doors and Windows are not equal to simple high-performance exterior Windows, it is an organic combination of performance systems, organic combination represents the design and development of the system mature and reliable, low energy consumption in the service life, low repair rate, low cost of use.

A simple comparison can be found that compared with ordinary broken bridge doors and Windows, the incremental cost of the ground construction area aperture of domestic and imported doors and Windows is 68 yuan /m2 and 213 yuan /m2, which is similar to the incremental cost of green building 2 stars and 3 stars, equivalent to 3% and 10% of the cost of ordinary residential ground construction and installation.

How big is the difference between the two types of doors and Windows in the cost of profiles?

• Ordinary broken bridge aluminum doors and Windows: profile unit price = aluminum ingot price + processing fee + heat insulation strip = 12+6+3=21 yuan /kg, according to the case window type content of 10kg/㎡ calculation, equivalent to the cost of the profile per square meter of doors and Windows is 210 yuan /㎡;

• Imported system doors and Windows: the price per square meter is generally 500~700 yuan /㎡, 1.5 times to 2 times more expensive, and the profile content is still about 10kg, the increase is not obvious, temporarily estimated by an increase of 20%, that is, the profile offer for the case data 565 yuan /m2 = 12kg*47 yuan /kg.

That is, the cost difference between the two profiles is 355 yuan /㎡.

System door and window energy saving examples

Example: 100m2 of two rooms and one living room, the window area is about 30m2. The heat insulation performance of system doors and Windows is better than that of ordinary doors and Windows.

Let's calculate the relevant data:

Conditions:

1. Open air conditioning with ordinary doors and Windows every day, and the power consumption is 30°.

2, with the system doors and Windows open the air conditioning every day, the power consumption is 25°.

3, the electricity charge is calculated at 1 yuan/hour. System window 1200 yuan/square meter, ordinary doors and Windows 800 yuan/square meter.

From this, it is calculated that 12000÷1825≈6.5 years!

Cost difference of doors and Windows: cost of system doors and Windows - cost of ordinary doors and Windows = 30* 1200-30 *800 =12000 yuan.

From this, it is calculated that 12000÷1825≈6.5 years!

The general design life of building housing is 70 years, we can recover the cost of building Windows in only 6 years, and the system doors and Windows make the building energy saving and efficiency for 64 years!

It seems that you are valuable in the tangible cost of profiles, hardware, etc., but the essence is intangible, and you are valuable in many aspects such as "research and development design, late service, and comprehensive performance". "R & D design" and other costs guarantee "comprehensive performance", so the supply price not only contains the visible cost of "comprehensive performance", but also carries the intangible cost of R & D design.

System doors and Windows have a longer average actual service life. According to the research of system Windows and doors abroad, "the average actual service life of system Windows is 15 to 30 years, while the actual service life of ordinary doors and Windows is 5 to 15 years", which shows the huge gap between system Windows and ordinary Windows.

The overall cost of system doors and Windows is lower. The construction cost of system doors and Windows is high, and the use cost is low; The construction cost of ordinary doors and Windows is low, and the use cost is high. The construction cost of system doors and Windows is more than 2 times that of ordinary doors and Windows, and the construction cost is a one-time input cost, which is relatively lower than the reduction of energy saving costs after amortization throughout the use period.

In summary, it can be seen that the system doors and Windows integrate all aspects of the door and window industry chain, and need to consider a series of important functions such as watertightness, air tightness, wind pressure resistance, mechanical and mechanical strength, heat insulation, sound insulation, anti-theft, shading, weather resistance, operation feel, etc., but also consider the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose and seals. The result is a high-performance system door and window. From the design to the final after-sales have the participation of the system window manufacturers, the system window has a higher cost performance than the traditional doors and Windows: good system stability, five characteristics of high requirements, high reliability, high average service life, low repair rate, low comprehensive cost.
