DOK glass is made of a very tough polymer film in the center. When the glass is broken by a violent impact, the composite film absorbs a large amount of impact energy and attenuates it rapidly, making it very difficult to penetrate the glass as a whole. In this way, when the building is hit by storms, earthquakes and other violent attacks, even if the glass is broken, it can still be kept intact within the frame of the windows and doors, avoiding damage to the interior caused by wind and rain and other foreign objects. At the same time, people inside and outside the building are protected from flying glass shards. When DOK glass is used in the lighting canopy, skylight, ceiling and elevated floor, even if the glass is broken, there is no fear of falling and injuring people.
Anti-theft: Because it is impossible to use a glass cutter to effectively cut the installed DOK glass. And normal people with other tools to penetrate the DOK glass time-consuming, loud, so by cutting or breaking the DOK glass into the room is very difficult and easy to be detected. DOK glass for malicious damage, theft and violent intrusion has a strong role in resisting.
Hurricane and Earthquake Resistance: DOK glass is a popular building material in hurricane and earthquake zones due to its ability to keep the pieces in place during and after breakage.
Durability: It is resistant to light, water, humidity, high temperature, etc.; and it does not absorb water.

Selection of Plastic Steel Profile (to meet the requirements of the international GB/T 8814-2004)
Affect the quality of Plastic Steel Profile several technical requirements:
①High Strength At least the thickness of the profile to ensure that the strength of the wind resistance to wind compression of the high hit 5000N/m3. (The wind pressure strength of the profile to ensure that the wind pressure strength of the high hit 5000N/m3. m3. (According to GB/T 7106-2002)
② good airtightness airtightness GB/T 7107-2002 up to the level of 5
③ watertightness watertightness GB/T 7108-2002 up to the level of 4
④ aging aging experiments of more than 5000 hours, equivalent to the standard of several decades of non-fading color?
From the actual small and medium-sized customers to choose plastic profiles, generally speaking, as long as the selection of authentic brand-name products, such as real, conch can be, do not be greedy for cheap, the selection of fake and shoddy products, the use of a period of time will be quality problems.
Hardware selection
Generally speaking, the selection of hardware will not affect the sound insulation performance, but the selection of good hardware to ensure that the product life.

Ventilator selection
Different ventilators use different anechoic principles, but there are contradictions in the principle of sound insulation and ventilation, the choice of ventilators generally sacrifice part of the acoustic performance in the noise environment is more harsh, low-frequency noise in the region of the high sound-sensitive people are advised not to install the window on the Ventilator.
Sealing tape
Sealing tape is good or bad directly affects the sound insulation performance of the window, the choice of sealing tape is mainly considered: ① the flexibility of the material itself, ② the elasticity of the material, ③ the material's aging resistance, ④ the material's thermal and acoustic
Commonly available on the market a few kinds of materials: ① ordinary PVC material, cheap, poor performance, ② modified PVC material, slightly better flexibility, poor elasticity, poor performance, ② the material of modified PVC, the material of modified PVC, the material of modified PVC, the material of modified PVC, the material of modified PVC. Softness is slightly better, poor elasticity, poor aging resistance, ③ EPDM material, softness, elasticity, aging resistance can be, often used in large-scale projects, ④ foam type EPDM material, with optimized performance. Our company specializes in the use of such materials as sealing tape.
The main function of the sealing tape is to seal, play the role of the window does not leak sound. Of course, it is impossible to rely on the adhesive tape to improve the sound insulation of the window.
In order to prevent soundproof windows from leaking due to gaps, the sealing tape is a closed, four corners should not leave gaps, if there are gaps will also cause sound leakage, affecting the sound insulation performance of the entire window.

Climate zoning
The transfer of energy is achieved through three forms of radiative transfer, convective transfer and heat transfer. Radiative transfer of energy includes visible light, infrared light and ultraviolet rays in the form of radiation. Convective transfer is due to the existence of a temperature difference between the two sides of the glass, causing the air to fall on the cold side and rise on the hot side, resulting in convection of air, resulting in the exchange of energy. Conduction transfer is achieved through the movement of the molecules of an object, driving the energy for movement. For different climatic conditions, the south and the north, the requirements for indoor heat insulation and thermal insulation are different, the cold northern regions require temperature collection and heat preservation, while the south requires heat insulation and cooling.

Energy-saving principle
In real life, people feel that the sunlight coming into the room from the window and the transportation equipment is too harsh, and the heat radiated into the room is too much, resulting in the energy consumption of air-conditioning equipment
How to effectively reduce the intensity of the sunlight transmitting into the room and the transportation vehicles, so that the incoming light is soft and comfortable, and to reduce the rate of transmittance of the sun's radiant energy as well as to reduce the energy consumption of air-conditioning, DOK thermal and acoustic glass is specially designed to solve this problem, which is the most important factor for energy saving. DOK insulated acoustic glazing is designed to solve this problem: solar control - saving energy and enjoying
Sunlight. As architectural design tends to use large glass surfaces in commercial and residential buildings, and as the accumulation of solar heat entering the room through the window glass increases, air conditioning and cooling become more demanding, DOK significantly reduces the energy consumption of air conditioning and cooling and ensures that the room is as comfortable as it would be under direct sunlight. In addition, the high degree of transparency allows us to fully utilize the visible part of the sunlight, which significantly reduces indoor lighting energy consumption. Combining high insulation with high light transmission
DOK's top-of-the-line products can block up to 90% of infrared light while maintaining nearly 70% of visible light transmission. By blocking 70% of the total solar energy from entering the room, it successfully reduces air-conditioning power consumption, saving energy usage and expenses. The abundance of natural light means that daylight can be "adopted", thus greatly reducing the need for artificial lighting.
Analysis of energy saving
The use of special radiation sensors to record the solar radiation through ordinary glass and DOK glass after the comparison of radiant heat: ordinary glass DOK glass Morning 100w/m 4w/m Noon (13:30) 780w/m 226w/m The above shows that, as a result of the use of DOK glass, so that the indoor heat of the solar radiation reduced by more than 71%, the radiant heat entering the day 71% or more, the whole day into the radiant heat and the cumulative value for the transparent glass for 3000 wh / m, while the DOK glass is only 870 wh / m, a reduction of 71%
