What is 4SG glass

4SG glass, also known as K ö dispace 4SG insulated glass system, is the new darling of the door and window market. Judging from its name, it is indeed confusing. Below, we will provide a detailed analysis for everyone. 4SG and TPS are inseparable, and it has been upgraded and developed from TPS dual channel sealing technology.

First, let's learn about the previous generation technology TPS, which stands for Thermo Plastic Spacer in English, translated as thermoplastic spacer. The new warm edge insulating glass system developed by TPS technology is made of special butyl rubber as an auxiliary material, filled with thermoplastic spacers of molecular sieves. Due to the uniform heat dissipation between the edges and surfaces of this insulated glass system, it is called a warm edge insulated glass system. The first insulating glass using TPS technology was invented and put into commercial use by the German Kemelin Group in 1974.

And 4SG is an upgraded version of the TPS flexible sealing spacer strip by the German company Kemering in 2005, which added other material ratios and upgraded it to a super sealing spacer strip. There are two main upgrades: one is to add integrated desiccants to improve the strength of the flexible sealant, solving the problem of unstable pressure and strength of the flexible spacer strip caused by oversized glass; Secondly, stronger adhesive materials have been added to ensure long-lasting strength and sealing. Compared to TPS products, it has higher bonding strength with glass and second sealant, better elastic recovery, and can maintain the same advantageous sealing performance. According to the report, the sealing system of 4SG+silicone structural adhesive is not only the sealing system that can maintain the excellent performance of insulating glass, but also the structural sealing system with the lowest argon gas leakage rate.

Advantages of 4SG Glass

(1） Thermal insulation

4SG glass uses special butyl rubber strips instead of traditional aluminum strips, greatly reducing thermal conductivity, effectively reducing thermal radiation and convection, and improving the thermal insulation of the glass edge. In the hot summer, the high temperature outside is difficult to pass through 4SG glass into the indoor environment, which helps to better maintain the cooling effect of indoor air conditioning and reduce its energy consumption; In the cold winter, indoor heat is not easily dissipated to the outside through glass, reducing the frequency and duration of heating equipment use, thereby reducing energy consumption and achieving energy conservation. For some households in northern regions, after installing 4SG glass, the indoor temperature significantly increases in winter and heating costs are also reduced significantly. It can also prevent condensation and mold from forming on doors and windows, improve the insulation performance of windows, reduce the "cold air effect" at the window edges, and maintain a stable and comfortable temperature indoors.

（2） Long term sealing

The special sealing process of 4SG glass is one of its highlights. It uses special butyl rubber mixed with molecular sieves for direct extrusion molding, greatly improving the consistency of the sealing material. At the same time, stronger adhesive materials have been added, in addition to physical bonding, chemical bonding has also been added, making the bonding more firm. This special process can effectively prevent gas leakage and water vapor infiltration. Experiments have shown that after 30 years of use, the comprehensive leakage rate of argon gas is only about 3%, and the water vapor/gas permeability far exceeds the national standard GB/T11944 by more than five times. The glass cavity is not easy to fog and condense, and can achieve long-term sealing effect, greatly improving the service life of the glass.

（3） Sound insulation and noise reduction

In terms of sound insulation and noise reduction, 4SG glass performs well. It adopts a sealing system of 4SG+silicone structural adhesive, which can retain the inert gas in the hollow glass for a long time, ensuring the retention of inert gas and achieving comprehensive sound insulation and noise reduction effect. When noise passes through glass, the glass enhances the reverse sound waves through unequal cavity widths, effectively resisting sound wave resonance and reducing the disturbance of noise to the living environment. For example, in houses next to urban main roads, installing 4SG glass significantly reduces indoor noise, effectively isolating external traffic noise, construction noise, and creating a quiet and comfortable living environment for people. Data shows that 4SG glass can reduce external noise by more than 30 decibels, making you feel like you are in a peaceful paradise

（4） Beautiful and durable

The appearance of 4SG glass is also outstanding, with a black matte surface. Most common door and window products on the market are compatible with black flexible spacers, which can achieve a unified visual effect, beautiful and coordinated appearance, and do not affect the style design of doors and windows. Whether it is modern minimalist style or European classical style decoration, 4SG glass can be perfectly matched. In terms of durability, 4SG glass has excellent anti-aging and corrosion resistance, can withstand the test of time and environment, and maintain good performance and appearance for a long time without frequent replacement, saving you cost and energy.

Application scenarios of 4SG glass

（1） Residential doors and windows

4SG glass is widely used in residential doors and windows, bringing many benefits to residents. In terms of thermal insulation, it can effectively block outdoor heat from entering the room, reduce indoor heat loss in cold winter, and maintain indoor warmth. Like Mr. Li's house in Beijing, which originally used ordinary glass, the indoor temperature is lower in winter and the heating cost is higher. After replacing with 4SG glass, the indoor temperature significantly increased, and the heating cost decreased significantly. Family members can also feel warm and comfortable indoors.

In terms of sound insulation and noise reduction, 4SG glass can effectively isolate external noise, allowing residents to enjoy a quiet living environment. Ms. Wang from Shanghai lives in a bustling urban area with high traffic noise. After installing 4SG glass, the indoor noise was significantly reduced, allowing her to work and rest in a quiet environment, greatly improving her quality of life. Moreover, the long-term sealing performance of 4SG glass can effectively prevent water vapor from entering, avoid glass fogging and condensation, ensure the clarity and aesthetics of the glass, extend the service life of doors and windows, and reduce the cost of replacing doors and windows in the later stage.

Residential units of different layouts can benefit from the application of 4SG glass. For small-sized residential units, the energy-saving properties of 4SG glass can reduce energy consumption, lower electricity bills, and allow small spaces to maintain comfortable temperatures. For large residential units, their sound insulation, noise reduction, and thermal insulation performance are more important, as they can create a quiet and comfortable environment for each room and enhance the comfort of living.

（2） Commercial buildings

In the field of commercial architecture, 4SG glass also performs well. Commercial buildings such as shopping malls and office buildings have high performance requirements for glass, and 4SG glass perfectly meets these needs. In shopping malls, the thermal insulation performance of 4SG glass can reduce the energy consumption of air conditioning systems and lower operating costs. Meanwhile, its excellent sound insulation and noise reduction performance can create a quiet and comfortable shopping environment for customers, enhancing their shopping experience. For example, in a large shopping mall, after installing 4SG glass, the indoor temperature was effectively controlled, the noise was significantly reduced, and customer satisfaction was greatly improved.

The use of 4SG glass in office buildings not only enhances the overall image of the building, but also provides a quiet and comfortable working environment for office personnel, improving work efficiency. Like some office buildings located in the city center with high surrounding noise, the installation of 4SG glass effectively isolates external noise, allowing office workers to focus on their work. Moreover, the aesthetic durability of 4SG glass enables office buildings to maintain a good appearance even after prolonged use, showcasing the strength and image of the enterprise.

How to choose 4SG glass

After understanding the advantages and application scenarios of 4SG glass, the next step is how to choose high-quality 4SG glass. When choosing 4SG glass, multiple factors need to be considered comprehensively to ensure that the purchased product meets the requirements and has reliable quality.

（1） Check brand and certification

Priority should be given to choosing 4SG glass from well-known brands, as well-known brands usually have better guarantees in terms of product quality, production technology, and after-sales service. For example, as the developer of 4SG glass, the German company Kemelin's products have a high level of popularity and good reputation in the market. Consumers can view the brand logo and relevant certifications of the product when making a choice, ensuring the source and quality of the product.

Common certifications for 4SG glass include CE certification, energy-saving certification, etc. CE certification is a mandatory certification in the EU market, indicating that the product complies with the requirements of relevant EU directives and coordinated standards; Energy saving certification reflects the performance advantages of products in terms of energy conservation. When purchasing, carefully check whether the product has these certification marks and the authenticity of the certification marks. You can check and verify through the official websites of relevant certification agencies to avoid purchasing counterfeit and inferior products. For example, some unscrupulous merchants may forge certification labels and sell ordinary glass as 4SG glass. If consumers do not carefully distinguish, they are easily deceived. Therefore, it is necessary to search for certification information through formal channels to ensure the authenticity and quality of the product.

（2） Check product quality

When checking the quality of 4SG glass, the first step is to observe its appearance. The surface of high-quality 4SG glass should be flat and smooth, without defects such as bubbles, impurities, scratches, etc., and the edges should be neat and undamaged. You can place the glass in a well lit area and observe the surface of the glass from different angles to see if there are any defects. If obvious bubbles or impurities are found on the surface of the glass, it may affect the performance and aesthetics of the glass, and it is not recommended to purchase.

Secondly, check the sealing performance. The sealing performance of 4SG glass is one of its key properties, which can be judged by checking the integrity and bonding condition of the sealing strip. The sealing strip should be uniform, continuous, and tightly bonded to the edge of the glass without cracking or peeling. You can gently press the sealing strip with your hand to feel its elasticity and bonding strength. If the elasticity of the sealing strip is insufficient or the bonding is not firm, it may cause gas leakage and water vapor infiltration, affecting the service life of the glass.

You can also check the insulation and sound insulation performance of the glass. Although precise testing may not be possible at the purchase site, preliminary judgments can be made through some simple methods. For example, touching the surface of glass with your hand to feel its temperature transfer, glass with good insulation performance will not have a significant increase in surface temperature when the external temperature is high; For sound insulation performance, it is possible to place the ear close to the glass in a noisy environment and listen to the size of external sounds. Glass with good sound insulation can effectively reduce the input of external noise.

（3）Make clear the prices and after-sales service

The price of 4SG glass will be affected by factors such as brand, specifications, and quality. Generally speaking, 4SG glass from well-known brands is relatively expensive, but its quality and performance are more guaranteed; The larger the specifications and the better the quality of the glass, the higher the price will be. When purchasing, choose products with high cost-effectiveness based on your budget and needs. The price range of 4SG glass from different brands may vary, so when choosing, don't just focus on the price and ignore the quality and performance of the product. You can consult several merchants to understand the market situation, compare the prices and performance of products of different brands and specifications, and make a reasonable choice.

After sales service is also very important. Choose a merchant or manufacturer that provides comprehensive after-sales service, so that when there are quality problems with the product, it can be repaired or replaced in a timely manner. To understand the after-sales service commitments of merchants or manufacturers, including warranty period, after-sales service response time, repair methods, etc. For example, some manufacturers offer a 30-year warranty period. During the warranty period, if the glass has problems such as sealing failure or fogging, the manufacturer will provide free repair or replacement; However, some merchants have a longer response time for after-sales service, which may affect consumers' user experience. Therefore, it is important to understand the relevant content of after-sales service before purchasing to ensure that one's rights are protected.
