Comparison of different exterior wall insulation systems 02 High efficiency door and window system and construction technology the external window insulation system includes three parts: Bridge broken aluminum alloy window frame, insulating glass, and Bridge broken node treatment technology for the connection between window frame and window opening.
In addition, light and temperature sensing elements and electric actuators can be further installed to realize intelligent full-automatic control.
Therefore, in the design and construction, certain thermal insulation methods should be adopted for positions such as window openings, balcony plates, protruding ring beams and structural columns to block their thermal bridges, so as to achieve better thermal insulation and energy-saving effect and increase comfort.
Therefore, external thermal insulation and facing dry hanging technology are the best external thermal insulation methods, whether from the perspective of thermal insulation effect or the firmness and safety of external facing installation.
Compared with the traditional partition drainage system, the drainage system on the same floor has the following advantages: sound insulation: the false wall can play the role of sound insulation and enhance the visual effect by adopting the installation mode in front of the wall.
05 At present, there are mainly two kinds of residential power ventilation systems used in Europe.
The form of external thermal insulation can effectively form the building thermal insulation system, achieve good thermal insulation effect and reduce the generation of thermal bridge.
Drainage on the same floor: the drainage branch pipe and the main drainage branch pipe on the same floor do not pass through the floor, and are connected to the main drainage riser on the same floor.
Independence: in the toilet, the pipeline does not pass through the floor and enjoys real property independence.
At present, the more advanced is the external shading system composed of tempered glass (ice glass).
Using high-performance doors and windows, the performance of glass is very important.
Effectively adjust the indoor air humidity, keep the room dry and comfortable at all times, and have a strong dehumidification effect on the humid air in Dalian in summer.
Compared with the external sunshade, the internal sunshade has a weak shielding effect on solar radiation, but it is necessary for residential buildings, whether from the perspective of privacy or anti glare.
The thermal insulation performance of high-performance glass products is one to several times higher than that of ordinary insulating glass.
Water saving: HDPE pipe with smooth inner surface and unique water tank design are adopted to improve the drainage effect of the system and realize the real water-saving function.
A sound insulation pad is added under the floor cushion to prevent indoor noise from being transmitted from upstairs.
Expel harmful gases that may exist for a long time caused by interior decoration.
Thermal bridge blocking technology has excellent technology and wide application abroad, such as eliminating the cold bridge structure of balcony floor, and Germany has very mature products, such as “embedded parts of reinforcement / insulating materials”.
When the sunshine is strong in summer, the roller shutter can be put down to effectively block the sun.
Reliable connection: the selected PE pipe adopts hot-melt connection, which not only has high connection strength, but also eliminates leakage and ensures safe use for 50 years.
12mm thick sliding translucent toughened glass push-pull sunshade inlaid panel air layer exterior wall coating, thermal insulation and the matching benefit of toughened glass and insulating glass of external window system of external sunshade system structure (from outside to inside).
The drainage noise treatment system drainage noise system – Drainage on the same floor.
Fresh air two degrees below room temperature forms a new wind tide on the ground, superimposes layer by layer, rises slowly, takes away the dirty gas in the human body, and finally is discharged through the exhaust hole.
The system consists of HDPE pipe system, concealed system installation components and sanitary ware trap matched with drainage on the same floor.
Economy: the same floor drainage technology is adopted to greatly reduce the number of force pipes, branch pipes and accessories of the system, with less materials and construction and high cost performance.
Secondly, the air layer between the thermal insulation layer and the external finish can form effective natural ventilation to reduce the temperature of air conditioning materials.
The same floor drainage system comes from Europe and has a history of 40 to 50 years.
Vanke project solution: the external sunshade system and external window system can effectively block outdoor noise.
For example, the thermal conductivity of single-sided coated Low-E insulating glass is about 1.7w / m2.
06 Drainage noise treatment system generally has the following types of indoor noise: outdoor noise is transmitted indoors through exterior walls and windows; The noise from upstairs activities is transmitted into the downstairs room through the floor; The noise generated by the impact of sewer water on the pipe wall.
It can be seen from the above schematic diagram of shading and noise prevention effects of different glass structures that the combined use of ice glass and insulating glass can not only have a good shading effect, but also minimize the impact of outdoor noise.
This product is embedded in the concrete floor during construction, which is simple and effective.
The combination of tempered glass and insulating glass insulates most of the sunshine and heat outdoors in summer to solve the problem of western sun exposure.
Combined with the architectural form, a certain form of adjustable external sunshade is installed in the South and west direction, which can be adjusted according to the use situation, so as to meet the requirements of sunshade in summer and not affect the requirements of daylighting and sunshine in winter.
Even if it is repaired, it does not need cross floor repair.
07 Central dust removal system the concept of central dust removal system is to separate the main machine from the dust collection area and discharge the filtered air outdoors, which not only solves the poor indoor hygiene, but also eliminates the secondary pollution after dust removal..
Although the system has not entered the Chinese market for a long time, it has developed rapidly and is widely used in Beijing, Shanghai and Guangdong.
It directly blocks 80% of the solar radiation heat outdoors, effectively reduces the air conditioning load and saves energy.
Freedom: the room type design and indoor space layout are more flexible.
Fresh air can be obtained without opening windows, reducing indoor heat loss and saving energy.
Working principle and function: fresh air from high altitude is continuously sent out from the air supply outlet at the bottom of the room at a low speed of 0.3m per second through filtration, dust removal, sterilization, heating / cooling, humidification / dehumidification and other treatment processes.
Performance comparison of different profiles 03 Thermal bridge blocking construction technology thermal bridge is a shortcut to heat transfer, which not only causes considerable cold and heat loss, but also local condensation.
The other is the ventilation system of external wall air inlet equipment + toilet air outlet + roof exhaust fan, which not only filters the air and reduces the noise, but also scientifically and reasonably ensures the indoor ventilation, discharges the humid and dirty air in the toilet, and has little noise interference.
