Anti-theft: Because it is impossible to effectively cut the installed DOK glass with glass cutter. Moreover, it takes a long time for normal people to break DOK glass with other tools, and the noise is loud, so it is difficult and easy to find cutting or breaking DOK glass into the room. DOK glass has strong resistance to vandalism, theft and violent invasion.
Hurricane and earthquake prevention: DOK glass is a building material that people are willing to use in hurricane and earthquake areas because it can keep the debris in place when it is broken or after it is broken.
Durability: light resistance, water resistance, moisture resistance, high temperature resistance, etc. And does not absorb water.

Selection of plastic-steel profiles (in line with the requirements of international GB/T 88 14-2004)
Several technical requirements affecting the quality of plastic-steel profiles;
① The strength is high, at least the profile thickness is guaranteed, and the high wind pressure is 5000N/m3 (according to GB/T 7 106-2002).
② Good air tightness. The air tightness of GB/T 7 107-2002 reaches Grade 5.
③ Good water tightness. The water tightness of GB/T 7 108-2002 reaches Grade 4.
(4) The anti-aging experiment lasts for more than 5,000 hours, which is equivalent to reaching the standard of colorfastness for decades.
Judging from the actual selection of plastic steel profiles by small and medium-sized customers, generally speaking, as long as you choose authentic brand-name products, such as Shide and Conch, you must not be greedy for small and cheap, and choose fake and shoddy products, which will lead to quality problems after a period of use.
Selection of hardware
Generally speaking, the choice of hardware will not affect the sound insulation performance, but the choice of good hardware can ensure the service life of the product.

Selection of ventilator
Different ventilators adopt different noise elimination principles, but there are contradictions in sound insulation and ventilation principles. Generally, some sound insulation performance will be sacrificed when choosing a ventilator. People who are sensitive to sound in areas with harsh noise environment and high low-frequency noise suggest that it is not appropriate to install ventilation fans on windows.
Sealing seam strip
The quality of sealant tape directly affects the sound insulation performance of windows. The selection of sealant tape mainly considers: ① the flexibility of the material itself, ② the elasticity of the material, ③ the aging resistance of the material, and ④ the heat insulation and sound insulation of the material.
Several common materials in the market: ① ordinary PVC material with low price and poor performance; ② Modified PVC material with better flexibility has poor elasticity and aging resistance; ③ EPDM material has good flexibility, elasticity and aging resistance, and is often used in large-scale projects; ④ The foamed EPDM material with the best performance. Our company specially uses this material as sealing tape.
The main function of sealing strip is to seal and play a role in not leaking window sound. Of course, rubber strip can't improve the sound insulation effect of windows.
In order to prevent the sound insulation window from leaking due to gaps, the sealing rubber strip is closed, and there should be no gaps at the four corners. If there is a gap, it will also cause sound leakage and affect the sound insulation performance of the whole window.

Climate zoning
Energy transfer is realized by radiation transfer, convection transfer and heat transfer. The energy transmitted by radiation includes visible light, infrared light and ultraviolet light in the form of radiation. Convection transfer is due to the temperature difference between the two sides of the glass, which makes the air fall on the cold side and rise on the hot side, resulting in air convection and energy exchange. Conductive transmission is to achieve the goal by driving energy movement through the movement of object molecules. For different climatic conditions, the requirements for indoor thermal insulation in the north and south are different. The cold area in the north requires temperature collection and heat preservation, and the south requires heat insulation and refrigeration.
The urban climate distribution in Design Standard for Energy Efficiency of Public Buildings (GB 50 189-2005) is as follows:
Climate zoning represents cities.

Energy saving principle
In real life, people think that the sunlight coming from the window is too dazzling, and too much heat radiates to indoor and transportation equipment, resulting in air conditioning equipment.
DOK thermal insulation sound insulation glass is specially designed to solve this problem: how to effectively reduce the intensity of sunlight entering indoor and traffic vehicles, make the incoming light soft and comfortable, reduce the transmittance of solar radiation energy, and reduce the energy consumption of air conditioners; how to control sunlight-save energy and enjoy it.
Sunshine. Architectural design tends to use large glass surfaces in commercial and residential buildings. When the accumulation of sunlight and heat entering the room from the window glass increases, higher requirements are put forward for air conditioning and refrigeration. DOK can significantly reduce the energy consumption of air conditioning and refrigeration, and ensure that the room is equally comfortable in direct sunlight. Moreover, high transparency enables us to make full use of the visible part of sunlight, thus significantly reducing indoor lighting energy consumption. Give consideration to high thermal insulation rate and high air permeability.
In terms of optics, DOK's top products can isolate up to 90% infrared rays while maintaining nearly 70% visible light transmittance. By preventing 70% of the total solar energy from entering the room, the electricity consumption of air conditioning is successfully reduced, and energy consumption and expenses are saved. Adequate natural light means that sunlight can be "adopted", thus greatly reducing the requirements for artificial lighting equipment.
Energy saving analysis
The comparison of solar radiation passing through ordinary glass and DOK glass was recorded with a special radiation sensor: the ordinary glass DOK glass was over 780 W/M226 W/m at noon 100w/m 4w/m (13: 30), indicating that the solar radiation heat entering the room was reduced by 71due to the adoption of DOK glass.
