Insulated GlassesBecause of its excellent thermal insulation, sound insulation, energy saving and other properties, it is widely used in architectural doors, windows, curtain walls and other fields. However, different application scenarios have different performance requirements for Insulated Glasses. Choosing the appropriate Insulated Glasses not only affects the comfort, energy efficiency and safety of the building, but also directly affects the balance of cost and performance. This article aims to help dealers, traders, door and window manufacturers and engineering projects make informed decisions when purchasing Insulated Glasses from the aspects of Insulated Glasses classification, its performance characteristics, applicable scenarios, customization suggestions and costs.
1. Classification of Insulated Glasses
Insulated Glasses can be divided into the following five categories according to structure and function:
1. Ordinary Insulated Glasses: Two or three pieces of glass, filled with dry air or inert gas (such as argon and krypton gas), suitable for general building doors and windows.
2. Low-EInsulated Glasses: Plated low-radiation film to reduce heat radiation and improve energy-saving effects. It is suitable for energy-saving buildings.
3. Laminated Insulating Glass: The outer layer is laminated glass, and the inner layer is a hollow structure, which is both safe and sound insulation, and is suitable for high-rise buildings, curtain walls, etc.
4. Vacuum glass: There is a vacuum layer between the two glasses, which has good thermal insulation performance, but is cost-effective, and is suitable for high-end buildings.
5. Intelligent dimming Insulated Glasses: adjustable light transmittance, suitable for high-end commercial buildings, sunrooms, etc.
2. Analysis of key parameters of Insulated Glasses
parameter | illustrate | Influence |
Glass thickness | Single-layer glass thickness (5~19mm) | Affect strength, sound insulation, cost |
Hollow layer thickness | 6A, 9A, 12A, 16A, etc. (A represents the air layer) | Affects the heat insulation and sound insulation effect |
Gas filling | Air, argon, krypton, etc. | Argon gas has lower thermal conductivity than air and has better energy saving effect |
Low-E film layer | Single silver, double silver, three silver Low-E | Energy-saving performance increases in turn, cost increases |
Spacer bar | Aluminum spacer strips, warm edge spacer strips | Warm edge spacing strips reduce thermal bridge effect and improve energy saving |
Sealant | Butyl glue + silicone glue/polysulfide glue | Influences the sealing and service life of Insulated Glasses |
Therefore, when selecting Insulated Glasses, you need to pay attention to the following main parameters:
① Glass thickness: The thickness of the glass affects its strength and sound insulation performance. Common thicknesses include 5mm, 6mm, etc. Thick glass has better sound insulation, but also increases costs.
② Hollow layer thickness: The thickness of the hollow layer is usually between 6mm and 20mm. The larger the thickness, the better the thermal insulation performance. But an overly thick hollow layer may cause the overall thickness of the glass, increasing the weight and cost of the doors and windows.
③ Gas filling type: Inert gases (such as argon and krypton) have better thermal insulation properties than air, so they are preferred in buildings that require higher energy efficiency.
Glass surface treatment: Some Insulated Glasses surfaces will be coated, such as low-emission (Low-E) glass, which can effectively improve the thermal insulation performance of the glass.
3. Performance characteristics of Insulated Glasses
① Thermal insulation performance: Insulated Glasses can effectively prevent external heat from being transferred into the room and keep the indoor temperature stable. Especially Insulated Glasses filled with argon, its thermal insulation performance is more outstanding.
② Sound insulation performance: Insulated Glasses can reduce the incoming of external noise, especially in urban or noisy environments. The use of thicker glass and wider hollow layers can significantly improve the sound insulation effect.
③ Safety: Insulated Glasses usually uses Toughened Glass or laminated glass as the substrate, which has high impact resistance. Toughened Glass is broken and becomes granular, preventing sharp debris from damaging the human body.
④ UV protection function: Some Insulated Glasses surfaces will be equipped with Low-E coating, which can effectively block UV rays and protect indoor furniture and floors from UV damage.
Comparison of performance characteristics of various types of glass
type | Thermal insulation | Sound insulation | Security | Applicable scenarios |
Normal Insulated Glasses | generally | better | generally | Ordinary residence, office |
Low-EInsulated Glasses | 优 | better | generally | Energy-saving buildings, cold/hot areas |
Laminated Insulating Glass | better | 优 | 高 | High-rise buildings, curtain walls, schools |
Vacuum glass | Extremely excellent | Extremely excellent | generally | High-end buildings, laboratories |
Smart dimming glass | 优 | better | generally | Commercial buildings, sunrooms |
4. Applicable scenarios and customization suggestions for Insulated Glasses
When customizing Insulated Glasses, it is recommended to consider the following aspects:
a. Climate conditions: Choose the appropriate Insulated Glasses type according to the climatic conditions of the region (temperature, humidity, etc.). For example, three layers of Insulated Glasses should be selected in cold areas, while glass with moisture-proof function can be selected in the southern humid and hot areas.
b. Architectural design: The size and shape of Insulated Glasses can be customized according to the architectural design, especially large-area glass windows and special-shaped glass curtain walls, which need to ensure sealing and stability during installation.
c. Safety requirements: If the building is located in a high-risk area, it is more appropriate to choose explosion-proof glass or high safety Insulated Glasses
The following Insulated Glasses configurations are recommended according to different scenarios:
1. Residential doors and windows
Recommended configuration: 5+12A+5 Low-EInsulated Glasses (argon filled)
Advantages: Energy saving, sound insulation, high cost performance
Customization suggestions: Double silver Low-E can be used in the northern region, and single silver Low-E can be used in the southern region.
2. Commercial buildings/curtain walls

5. If there are high requirements for energy-saving performance, please refer to the following for customization suggestions:
l Low-E film layer: Single silver Low-E can reduce heat loss by 30%, and double silver/three silver is better.
l Gas filling: Argon gas saves about 10% energy than air, krypton gas has better effect but higher cost.
l Warm edge spacing strip: reduces edge heat conduction and improves energy saving in the entire window.
6. If there are high requirements for sound insulation performance, please refer to the following for customization suggestions:
l Hollow layer thickness: 12A~16A good sound insulation effect.
l Laminated layer: PVB laminated glass can effectively reduce low-frequency noise (such as traffic noise).
l Asymmetric glass thickness: such as 6+12A+5, it can reduce resonance and improve sound insulation.
7. If safety is required, the following customization suggestions can be considered:
l Toughened Glass: Strong impact resistance, it becomes granular after crushing, reducing damage.
l Laminated glass: Even if it is broken, it will still be glued together to prevent falling.
l Explosion-proof glass: suitable for high-risk places such as banks and airports.
5. The cost of Insulated Glasses
Cost is an important consideration when choosing Insulated Glasses. The prices of different types of Insulated Glasses vary greatly. Generally speaking:
① Double floor Insulated Glasses is relatively cheap and suitable for ordinary residential and low-rise buildings.
② The cost of three floors Insulated Glasses is relatively high, but the thermal and sound insulation performance is better, making it suitable for buildings with high requirements for energy efficiency.
③ Special customized glass (such as explosion-proof, vacuum glass, etc.) will significantly increase costs, but can provide higher safety and performance.
