Europe is the birthplace of system doors and windows. Since 1983, European doors and windows brands have entered China one after another, and so far there have been nearly two decades. Everyone knows that system doors and windows are good and expensive, but where is the good thing about system doors and windows? Today, let's share those things about system doors and windows!
Doors and windows system & ne; System doors and windows
First of all, these are two concepts. The door and window system is a big whole, and the system door and window are only the products in this big whole. No matter design, production, sales, after-sales and many other links are part of this door and window system. That is, system doors and windows are doors and windows products that can effectively guarantee the building performance produced strictly according to the standards of doors and windows system.
Where are the system doors and windows?
1 A series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, Operation feel and so on are comprehensively considered. At the same time, equipment, comprehensive results of the performance of profiles, accessories, glass, viscose and seals, and make a clear commitment to the performance, quality and after-sales indicators of the products.
2 it has good advantages such as low energy consumption, safety, comfort, noise reduction and high sealing performance, which not only meets users' pursuit of quality life, but also maximizes the benefits of energy saving and consumption reduction.
3 Strong stability, system doors and windows are mature products launched after a long period of deliberation and research and development, comprehensive testing of materials, performance and quality of the entire doors and windows, and reaching the expected standards.
Selection of system doors and windows in material, craft and price system
Material
Profile:
Different profiles have different properties, mainly because heat-conduction coefficient determines the energy consumption of doors and windows, so the section design of profiles is very important.
Glass:
The loss of energy is mainly caused by convection, conduction and radiation. System doors and windows will be selected according to different regions. For example, the southern region belongs to the hot summer and warm winter region. Glass with low heat reflection should be selected to meet different building needs in different regions, select glass with corresponding heat transfer coefficient and shading coefficient.
Hardware accessories:
Hardware accessories play a very important role in energy-saving doors and windows. They are not only closely related to the air tightness, water tightness and wind pressure resistance of doors and windows, but also play a very important role in safety and other performance.
Craft
Angle setting process:
Most of the corner connections of system doors and windows are made of special cast aluminum corner codes with hollow stainless steel pin glue injection, and a grooved stainless steel or aluminum alloy clamp unit is installed at the thin edge splicing of the profile, it can completely guarantee the sealing of the splicing place.
Sealant strip:
The corners of the glue strip of the system doors and windows are continuous, and the breakpoint is in the middle position of the upper part that is not easy to enter water. The L-type glue angle connection is used to fundamentally solve the problem of water seepage of the glue strip.
Price
System doors and windows seem to be expensive in tangible costs such as profiles and hardware, but in essence, they are expensive in "research and development design, post-service, comprehensive performance" and other aspects. Cost investment such as R & D and design ensures comprehensive performance. Therefore, the price not only includes the visible cost of comprehensive performance, but also bears intangible costs such as R & D and design.
The construction cost of system doors and windows is high, 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 twice that of ordinary doors and windows, while the construction cost is one-time input cost, which is relatively lower than the reduction of energy-saving cost after Amortization to the whole use period.
System doors and windows cannot be simply equal to energy saving and high performance painting. System doors and windows are a perfect organic combination of performance systems. With the continuous expansion of the domestic construction market, the voices of low carbon, building energy conservation and living environment are rising day by day, and the wide application of high-performance system doors and windows still has a long way to go.
