China's modern building doors and windows industry has been developing since the early 1980s. It has gone through 30 years of market baptism and evolution. The poor performance of ordinary doors and windows has always dominated the market in China, and the building doors and windows are still the major energy-consuming households in China.
Europe developed high-performance system doors and windows in the 1980s, and entered the Chinese market in the late 1990s. Its energy consumption is only about 1/4 of the energy consumption of building doors and windows in China.
With the goal of building a well-off society in an all-round way in the 13th Five-Year Plan has entered the decisive stage and the victory is in sight, the living standard of our people and the energy-saving standard of buildings are increasing day by day, and the attention of the society to the external window system has gradually developed from the five-character requirement of doors and windows to the comprehensive performance indicators of paying more attention to durability and comfort. Traditional doors and windows are becoming increasingly difficult to meet the high-quality needs and adapt to the development of green buildings. Systematic doors and windows will meet the development period.
This article will explain the concept, advantages, cost analysis and selection of system doors and windows in detail.
Where is it?
System doors and windows are better than ordinary doors and windows.
Higher reliability and cost performance
The definition of system Windows given in the Technical Guidelines for Doors and Windows of Building Systems (RISN-TG026-2016) is:
The door and window system is designed, manufactured and installed in accordance with strict procedures based on different climatic environment and functional requirements. It has high reliability and cost-effective building doors and windows.
1. System doors and windows are an organic combination of performance systems. The industry compares the difference between system windows and energy-saving windows vividly as "brand computers" and "assembled computers". Systematic doors and windows company is different from ordinary doors and windows manufacturer. Systematic doors and windows company integrates all technology, materials and equipment of doors and windows from the whole industry chain, provides a series of system solutions to downstream doors and windows processing enterprises, and guarantees the quality of the whole window. System doors and windows are not the same as simple high-performance 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 service life, low repair rate, low use cost.
2. The system doors and windows have longer average actual service life. According to the research of foreign system windows and doors, the average actual service life of system windows is 15-30 years, while that of ordinary doors and windows is 5-15 years. This shows that there is a huge gap between system windows and ordinary windows.
3. System doors and windows are divided into two categories: closed system and semi-closed system. Closed system doors and windows have unique door and window system technology, its hardware matching slots are special fittings slots, poor versatility, hardware fittings have no selectivity, must use its special matching products; semi-closed system because of its openness, hardware fittings will have a variety of combinations.
4. The comprehensive cost of system doors and windows is lower. The construction cost of the system doors and windows is high and the use cost is low. The construction cost of the ordinary doors and windows is low and the use cost is high. The construction cost of system doors and windows is more than twice that of ordinary doors and windows, while the construction cost is a one-time investment cost, which is relatively lower than the reduction of energy-saving cost after amortization to the whole use period.
In conclusion, the system windows and doors integrate all aspects of the industry chain. From design to the final after-sale, the manufacturers of the system windows are involved. The system windows have higher cost-performance ratio than the traditional windows and doors: good system stability, high five-sex requirements, high reliability, high average service life, low repair rate and low comprehensive cost. So, as an excellent product portfolio, how to make the right choice?
Where are you?
Profiles, Glass, Hardware Accessories, Sealant Strips, Frames
All of them are the key factors influencing the cost analysis of system doors and windows.
System windows are more expensive than our ordinary energy-saving windows because of many reasons:
1. R&D design: The design and development of system windows need a period of 2-3 years, and then it will take 2-3 years to test and test the system windows before they can be put into the market. The R&D test of system windows is more complex than that of ordinary windows, and the cost of R&D and design of system windows is higher than that of energy-saving windows.
2. Post-service: System window manufacturers are involved in the design, construction and post-service, and provide system solutions. Their human and financial investment is large, and their costs are high.
3. Comprehensive performance: The performance of the system window should be considered in a series of performances, such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance and operation feel, which determines that the composition of its doors and windows is much higher than that of ordinary windows in terms of product performance and quality index.
