LOW EInsulated Glasses type
1. Single silver/double silver/three silver LOW-E, the more coated layers, the stronger the insulation performance and the higher the cost.
2. High-transparency type (such as CEB11), suitable for cold northern areas
3. Sunshade type (such as SEB12), suitable for hot southern areas.
4. If the hollow structure is filled with argon, it can further improve the thermal insulation effect.
LOW EInsulated Glasses Common combination methods
LOW-EInsulated Glasses is a high-performance glass that combines low-radiation coating and hollow structure.
1. Single silver LOW-EInsulated Glasses, cost-effective and suitable for most climates.
Common combinations such as: 6mmToughened Glass (outer layer) + 12mm hollow layer (argon) + 6mm LOW-E glass (inner layer), or 5mm glass (outer layer) + 9A hollow layer + 5mm LOW-E glass (inner layer)
2. Double silver LOW-EInsulated Glasses has stronger thermal insulation performance and higher visible light transmittance, which is suitable for buildings with high energy conservation and lighting requirements. Common combinations such as: 6mmToughened Glass (outer layer) + 12A argon + 6mm double silver LOW-E glass (inner layer)
3. Sanyin LOW-EInsulated Glasses, with extreme heat insulation and light transmission, suitable for ultra-low energy consumption buildings or glass curtain walls. Common combinations such as: 6mm glass (outer layer) + 16A hollow layer + 6mm three-silver LOW-E glass (inner layer)
4. Combined with sunlight control glass, it can reflect some solar radiation, reduce glare, and is suitable for hot areas. Common combinations such as: 6mm heat reflective glass (outer layer) + 12A + 6mm LOW-E glass (inner layer)
5. The laminate + LOW-E hollow combination, the laminate layer can prevent explosions and improve safety. At the same time, the hollow layer can enhance heat insulation, and is suitable for curtain walls or high-rise buildings. Common combinations such as: 6mm laminated glass (outer layer) + 12A + 6mm LOW-E glass (inner layer)
6. Three-glass and two-cavity structure has double hollow layers, so it has better thermal insulation performance and is suitable for severe cold or high-noise environments. Common combinations such as: 5mm glass (outer layer) + 6A + 5mm LOW-E glass (middle layer) + 6A + 5mm glass (inner layer)
Our factory's LOW EInsulated Glasses processing and production specifications
Glass type can be selected as float glass, ultra-white glass, Toughened Glass, etc.
Maximum size 3300mm×7000mm.
The thickness of glass is usually 5~19mm.
Single-layer LOW-E glass is usually 4-6mm.
Insulated GlassesTotal thickness (two pieces of glass + spacer layer) is commonly found in 12mm, 16mm, 20mm, 24mm, etc. For example: 5mm glass + 12mm spacer layer + 5mm glass = total thickness 22mm. The thickness of the hollow layer is recommended by our factory. Too thin affects heat insulation, and too thick may increase weight and cost.
Hollow combination: such as '5mm+12A+5mm' (glass thickness + spacer layer thickness + glass thickness).
The thickness of the spacer layer can be selected from 6A, 9A, 12A, and 16A (A is the air layer, 1A=1mm). Among them, 12A and 16A have the best thermal insulation effect, and excessive thickness may reduce performance due to gas convection.
Inert gas filling can be selected for inert gases such as argon (Ar) and krypton (Kr), which can improve thermal insulation performance (the U value is reduced by about 15%).
The spacer material can be made of aluminum spacer (traditional) or warm edge spacer (such as TPS, stainless steel, which can reduce edge thermal bridges).

Our factory LOW EInsulated Glasses performance indicators
Low eInsulated Glasses specifications need to be comprehensively determined based on building needs, energy-saving standards and production processes. Therefore, the processing and production specifications of LOW-EInsulated Glasses involve multiple key parameters and technical requirements. The specific specifications need to be adjusted in combination with the project climate (such as lower U value in severe cold areas), building orientation (such as low SC value in high sunshine areas) and design specifications (such as green construction standards). Low eInsulated Glasses Our factory can provide customized services. Before production, our factory can provide customers with samples for actual performance measurement to ensure that they meet design requirements.
Heat transfer coefficient (U value): Single silver LOW-EInsulated Glasses is 1.1-1.6 W/(m²·K); double silver LOW-E+argon can be as low as 0.9-1.1 W/(m²·K).
The sunshade coefficient (SC) is 0.2-0.7. The more complex the film system, the lower the SC (the better the sunshade effect).
Visible light transmission ratio (VLT): 30%-70%, selected according to building lighting needs.

Our factory's LOW EInsulated Glasses processing process
LOW-EInsulated Glasses is an energy-saving glass. Its processing technology combines coating technology with Insulated Glasses manufacturing technology. The core lies in plating a low-emissivity film layer on the surface of the glass, and then improving thermal and sound insulation performance through a hollow structure.
1. According to the order requirements, accurately cut the original glass into the specified size, clean and dry it through high-pressure spraying and brush.
2. If safety performance is required, temper the original sheet or interlayer treatment before coating.
3. Low-E film plating and detection
4. Pair the coated glass with another piece of normal glass or Toughened Glass
5. Install warm edge spacer strips or traditional aluminum spacer strips, and fill them with 3A molecular sieve desiccant
6. Coat hot melt butyl glue on the contact surface of the spacer strip and glass (primary seal)
7. Coat polysulfide glue or silicone glue (two-component sealant) on the edge of the glass
8. Fill the hollow layer with argon (Ar) or krypton gas (Kr) and detect the airtightness
9. After completion of low eInsulated Glasses, curing under constant temperature and humidity environment
10. Detection performance, including dew point test, ultraviolet irradiation and anti-condensation test, etc.
11. Our factory adopts vertical packaging, with edges protected by angle protection to avoid scratches on the membrane layer, and then stored in a dry and ventilated warehouse to stay away from acid and alkali corrosive substances.
Quality standards of our factory

Our factory LOW EInsulated Glasses core features
1. Excellent thermal insulation performance, LOW-E coating can reflect more than 80% of far-infrared thermal radiation (such as heat in summer sunshine or indoor heating heat in winter), reducing heat transfer. The hollow layer (usually filled with inert gas such as argon) works synergistically with the LOW-E film, which can greatly reduce the U value of the heat transfer coefficient of the glass and improve the insulation effect.
2. High efficiency and energy saving. It can reduce the outflow of indoor heat in winter, block the entry of outdoor heat radiation in summer, reduce the energy consumption of air conditioning and heating, and the energy saving rate can reach 30%-50%. It is warm in winter and cool in summer. Comply with green building standards and is very suitable for passive houses, LEED certified buildings, etc.
3. Selective light transmission, where high visible light transmittance can allow sufficient natural light to enter (visible light transmittance can reach 40%-70%), reducing lighting needs. Secondly, it can block ultraviolet rays, filter more than 90% of ultraviolet rays, and protect indoor furniture, floors, etc. from fading and aging.
4. Sound insulation and noise reduction, where the hollow structure can absorb sound waves, and the double-layer or multi-layer glass + air/gas layer can effectively reduce noise, with a noise reduction of about 30-40 decibels, especially for high-frequency noises, such as traffic sounds.
5. Anti-condensation, because the hollow layer causes the temperature on the inner side of the glass to be close to room temperature, it is not easy to condensate in cold weather, and can maintain a clear field of view.
6. With diversified design, the film layer position can be adjusted, and the LOW-E film can be plated on different surfaces of Insulated Glasses (such as the second and third sides), so it can adapt to different climate needs (such as the south focusing on sunshade and the north focusing on thermal insulation). At the same time, it can also combine other technologies (such as double silver/three silver LOW-E, laminated glass, colored glazed glass, etc.) to meet the needs of light transmission, privacy, and beauty, and flexibly match.
7. Long service life, and the hollow layer sealing process (such as warm edge spacer strips, butyl glue) ensures stable long-term performance. Therefore, the LOW-E film is located in the sealed layer and is not easy to oxidize.
